Starting navigation in Waze with Android's Intents

Starting navigation in Waze with Android's Intents - android

I have a simple Android app which should be able to allow navigation between 2 GeoPoint's.
I can easily display a GeoPoint on Waze, writing this small piece of code:
String uri = "waze://?ll=40.761043, -73.980545&z=10";
startActivity(new Intent(android.content.Intent.ACTION_VIEW, Uri.parse(uri)));
But, what I really need is a way to display navigation directions between 2 points.
I've tried to locate the correct BroadcastReciever in the Waze source, but I stopped follow when it got to native calls (JNI) because I have no idea where the actual call is... I reached only to the URIHandler signature, with no success finding the implementation...
Any ideas?
Thanks.

Fix you uri to:
String uri = "waze://?ll=40.761043, -73.980545&navigate=yes";
(added navigate=yes) and you should be good.

If this is still relevant you can use this:
String uri = "geo: latitude,longtitude";
startActivity(new Intent(android.content.Intent.ACTION_VIEW,
Uri.parse(uri)));

Today's Waze base url is https://waze.com/ul so to navigate you have to use
https://waze.com/ul?ll=45.6906304,-120.810983&navigate=yes

You can do [kotlin]:
fun openWaze(latitude: Double, longitude: Double) {
packageManager?.let {
val url = "waze://?ll=$latitude,$longitude&navigate=yes"
val intent = Intent(Intent.ACTION_VIEW, Uri.parse(url))
intent.resolveActivity(it)?.let {
startActivity(intent)
} ?: run {
Toast.makeText(context, R.string.noWazeAppFound, Toast.LENGTH_SHORT).show()
}
}
}

According to Google doc about working with Waze you can use code below to open waze from your android app:
try {
// Launch Waze to look for Hawaii:
String url = "https://waze.com/ul?ll=40.761043,-73.980545&navigate=yes";
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
startActivity(intent);
} catch (ActivityNotFoundException ex) {
// If Waze is not installed, open it in Google Play:
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse("market://details?id=com.waze"));
startActivity(intent);
}

How to open Google play store app directly without chooser intent [duplicate]

I have open the Google Play store using the following code
Intent i = new Intent(android.content.Intent.ACTION_VIEW);
i.setData(Uri.parse("https://play.google.com/store/apps/details?id=my packagename "));
startActivity(i);.
But it shows me a Complete Action View as to select the option (browser/play store). I need to open the application in Play Store directly.

You can do this using the market:// prefix.
Java
final String appPackageName = getPackageName(); // getPackageName() from Context or Activity object
try {
startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("market://details?id=" + appPackageName)));
} catch (android.content.ActivityNotFoundException anfe) {
startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("https://play.google.com/store/apps/details?id=" + appPackageName)));
}
Kotlin
try {
startActivity(Intent(Intent.ACTION_VIEW, Uri.parse("market://details?id=$packageName")))
} catch (e: ActivityNotFoundException) {
startActivity(Intent(Intent.ACTION_VIEW, Uri.parse("https://play.google.com/store/apps/details?id=$packageName")))
}
We use a try/catch block here because an Exception will be thrown if the Play Store is not installed on the target device.
NOTE: Any app can register as capable of handling the market://details?id=<appId> URI. If you want to specifically target Google Play, the solution in Berťák's answer is a good alternative.

Many answers here suggest to use Uri.parse("market://details?id=" + appPackageName)) to open Google Play, but I think it is insufficient in fact:
Some third-party applications can use its own intent-filters with "market://" scheme defined, thus they can process supplied Uri instead of Google Play (I experienced this situation with e.g.SnapPea application). The question is "How to open the Google Play Store?", so I assume, that you do not want to open any other application. Please also note, that e.g. app rating is only relevant in GP Store app etc...
To open Google Play AND ONLY Google Play I use this method:
public static void openAppRating(Context context) {
// you can also use BuildConfig.APPLICATION_ID
String appId = context.getPackageName();
Intent rateIntent = new Intent(Intent.ACTION_VIEW,
Uri.parse("market://details?id=" + appId));
boolean marketFound = false;
// find all applications able to handle our rateIntent
final List<ResolveInfo> otherApps = context.getPackageManager()
.queryIntentActivities(rateIntent, 0);
for (ResolveInfo otherApp: otherApps) {
// look for Google Play application
if (otherApp.activityInfo.applicationInfo.packageName
.equals("com.android.vending")) {
ActivityInfo otherAppActivity = otherApp.activityInfo;
ComponentName componentName = new ComponentName(
otherAppActivity.applicationInfo.packageName,
otherAppActivity.name
);
// make sure it does NOT open in the stack of your activity
rateIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
// task reparenting if needed
rateIntent.addFlags(Intent.FLAG_ACTIVITY_RESET_TASK_IF_NEEDED);
// if the Google Play was already open in a search result
// this make sure it still go to the app page you requested
rateIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
// this make sure only the Google Play app is allowed to
// intercept the intent
rateIntent.setComponent(componentName);
context.startActivity(rateIntent);
marketFound = true;
break;
}
}
// if GP not present on device, open web browser
if (!marketFound) {
Intent webIntent = new Intent(Intent.ACTION_VIEW,
Uri.parse("https://play.google.com/store/apps/details?id="+appId));
context.startActivity(webIntent);
}
}
The point is that when more applications beside Google Play can open our intent, app-chooser dialog is skipped and GP app is started directly.
UPDATE:
Sometimes it seems that it opens GP app only, without opening the app's profile. As TrevorWiley suggested in his comment, Intent.FLAG_ACTIVITY_CLEAR_TOP could fix the problem. (I didn't test it myself yet...)
See this answer for understanding what Intent.FLAG_ACTIVITY_RESET_TASK_IF_NEEDED does.

Go on Android Developer official link as tutorial step by step see and got the code for your application package from play store if exists or play store apps not exists then open application from web browser.
Android Developer official link
https://developer.android.com/distribute/tools/promote/linking.html
Linking to a Application Page
From a web site: https://play.google.com/store/apps/details?id=<package_name>
From an Android app: market://details?id=<package_name>
Linking to a Product List
From a web site: https://play.google.com/store/search?q=pub:<publisher_name>
From an Android app: market://search?q=pub:<publisher_name>
Linking to a Search Result
From a web site: https://play.google.com/store/search?q=<search_query>&c=apps
From an Android app: market://search?q=<seach_query>&c=apps

While Eric's answer is correct and Berťák's code also works. I think this combines both more elegantly.
try {
Intent appStoreIntent = new Intent(Intent.ACTION_VIEW, Uri.parse("market://details?id=" + appPackageName));
appStoreIntent.setPackage("com.android.vending");
startActivity(appStoreIntent);
} catch (android.content.ActivityNotFoundException exception) {
startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("https://play.google.com/store/apps/details?id=" + appPackageName)));
}
By using setPackage, you force the device to use the Play Store. If there is no Play Store installed, the Exception will be caught.

try this
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setData(Uri.parse("market://details?id=com.example.android"));
startActivity(intent);

All of the above answers open Google Play in a new view of the same app, if you actually want to open Google Play (or any other app) independently:
Intent launchIntent = getPackageManager().getLaunchIntentForPackage("com.android.vending");
// package name and activity
ComponentName comp = new ComponentName("com.android.vending",
"com.google.android.finsky.activities.LaunchUrlHandlerActivity");
launchIntent.setComponent(comp);
// sample to open facebook app
launchIntent.setData(Uri.parse("market://details?id=com.facebook.katana"));
startActivity(launchIntent);
The important part is that actually opens google play or any other app independently.
Most of what I have seen uses the approach of the other answers and it was not what I needed hopefully this helps somebody.
Regards.

You can check if the Google Play Store app is installed and, if this is the case, you can use the "market://" protocol.
final String my_package_name = "........." // <- HERE YOUR PACKAGE NAME!!
String url = "";
try {
//Check whether Google Play store is installed or not:
this.getPackageManager().getPackageInfo("com.android.vending", 0);
url = "market://details?id=" + my_package_name;
} catch ( final Exception e ) {
url = "https://play.google.com/store/apps/details?id=" + my_package_name;
}
//Open the app page in Google Play store:
final Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_WHEN_TASK_RESET);
startActivity(intent);

use market://
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse("market://details?id=" + my_packagename));

As the official docs use https:// instead of market://, this combines Eric's and M3-n50's answer with code reuse (don't repeat yourself):
Intent intent = new Intent(Intent.ACTION_VIEW)
.setData(Uri.parse("https://play.google.com/store/apps/details?id=" + getPackageName()));
try {
startActivity(new Intent(intent)
.setPackage("com.android.vending"));
} catch (android.content.ActivityNotFoundException exception) {
startActivity(intent);
}
It tries to open with the GPlay app if it exists and falls back to default.

Some of the answers to this question are outdated.
What worked for me (in 2020) was to explicitly tell the intent to skip the chooser and directly open the play store app, according to this link:
"If you want to link to your products from an Android app, create an
Intent that opens a URL. As you configure this intent, pass
"com.android.vending" into Intent.setPackage() so that users see your
app's details in the Google Play Store app instead of a chooser."
This is the Kotlin code I used to direct users to viewing the app containing the package name com.google.android.apps.maps in Google Play:
val intent = Intent(Intent.ACTION_VIEW).apply {
data = Uri.parse("http://play.google.com/store/apps/details?id=com.google.android.apps.maps")
setPackage("com.android.vending")
}
startActivity(intent)
I hope that helps someone!

Kotlin:
Extension:
fun Activity.openAppInGooglePlay(){
val appId = BuildConfig.APPLICATION_ID
try {
this.startActivity(Intent(Intent.ACTION_VIEW, Uri.parse("market://details?id=$appId")))
} catch (anfe: ActivityNotFoundException) {
this.startActivity(
Intent(
Intent.ACTION_VIEW,
Uri.parse("https://play.google.com/store/apps/details?id=$appId")
)
)
}}
Method:
fun openAppInGooglePlay(activity:Activity){
val appId = BuildConfig.APPLICATION_ID
try {
activity.startActivity(Intent(Intent.ACTION_VIEW, Uri.parse("market://details?id=$appId")))
} catch (anfe: ActivityNotFoundException) {
activity.startActivity(
Intent(
Intent.ACTION_VIEW,
Uri.parse("https://play.google.com/store/apps/details?id=$appId")
)
)
}
}

You can do:
final Uri marketUri = Uri.parse("market://details?id=" + packageName);
startActivity(new Intent(Intent.ACTION_VIEW, marketUri));
get Reference here:
You can also try the approach described in the accepted answer of this question:
Cannot determine whether Google play store is installed or not on Android device

Very late in the party Official docs are here. And code described is
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setData(Uri.parse(
"https://play.google.com/store/apps/details?id=com.example.android"));
intent.setPackage("com.android.vending");
startActivity(intent);
As you configure this intent, pass "com.android.vending" into Intent.setPackage() so that users see your app's details in the Google Play Store app instead of a chooser.
for KOTLIN
val intent = Intent(Intent.ACTION_VIEW).apply {
data = Uri.parse(
"https://play.google.com/store/apps/details?id=com.example.android")
setPackage("com.android.vending")
}
startActivity(intent)
If you have published an instant app using Google Play Instant, you can launch the app as follows:
Intent intent = new Intent(Intent.ACTION_VIEW);
Uri.Builder uriBuilder = Uri.parse("https://play.google.com/store/apps/details")
.buildUpon()
.appendQueryParameter("id", "com.example.android")
.appendQueryParameter("launch", "true");
// Optional parameters, such as referrer, are passed onto the launched
// instant app. You can retrieve these parameters using
// Activity.getIntent().getData().
uriBuilder.appendQueryParameter("referrer", "exampleCampaignId");
intent.setData(uriBuilder.build());
intent.setPackage("com.android.vending");
startActivity(intent);
For KOTLIN
val uriBuilder = Uri.parse("https://play.google.com/store/apps/details")
.buildUpon()
.appendQueryParameter("id", "com.example.android")
.appendQueryParameter("launch", "true")
// Optional parameters, such as referrer, are passed onto the launched
// instant app. You can retrieve these parameters using Activity.intent.data.
uriBuilder.appendQueryParameter("referrer", "exampleCampaignId")
val intent = Intent(Intent.ACTION_VIEW).apply {
data = uriBuilder.build()
setPackage("com.android.vending")
}
startActivity(intent)

Ready-to-use solution:
public class GoogleServicesUtils {
public static void openAppInGooglePlay(Context context) {
final String appPackageName = context.getPackageName();
try {
context.startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("market://details?id=" + appPackageName)));
} catch (android.content.ActivityNotFoundException e) { // if there is no Google Play on device
context.startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("https://play.google.com/store/apps/details?id=" + appPackageName)));
}
}
}
Based on Eric's answer.

Kotlin
fun openAppInPlayStore(appPackageName: String) {
try {
startActivity(Intent(Intent.ACTION_VIEW, Uri.parse("market://details?id=$appPackageName")))
} catch (exception: android.content.ActivityNotFoundException) {
startActivity(Intent(Intent.ACTION_VIEW, Uri.parse("https://play.google.com/store/apps/details?id=$appPackageName")))
}
}

This link will open the app automatically in market:// if you are on Android and in browser if you are on PC.
https://play.app.goo.gl/?link=https://play.google.com/store/apps/details?id=com.app.id&ddl=1&pcampaignid=web_ddl_1

If you want to open Google Play store from your app then use this command directy: market://details?gotohome=com.yourAppName, it will open your app's Google Play store pages.
Web: http://play.google.com/store/apps/details?id=
App: market://details?id=
Show all apps by a specific publisher
Web: http://play.google.com/store/search?q=pub:
App: market://search?q=pub:
Search for apps that using the Query on its title or description
Web: http://play.google.com/store/search?q=
App: market://search?q=
Reference: https://tricklio.com/market-details-gotohome-1/

Here is the final code from the answers above that first attempts to open the app using the Google play store app and specifically play store, if it fails, it will start the action view using the web version:
Credits to #Eric, #Jonathan Caballero
public void goToPlayStore() {
String playStoreMarketUrl = "market://details?id=";
String playStoreWebUrl = "https://play.google.com/store/apps/details?id=";
String packageName = getActivity().getPackageName();
try {
Intent intent = getActivity()
.getPackageManager()
.getLaunchIntentForPackage("com.android.vending");
if (intent != null) {
ComponentName androidComponent = new ComponentName("com.android.vending",
"com.google.android.finsky.activities.LaunchUrlHandlerActivity");
intent.setComponent(androidComponent);
intent.setData(Uri.parse(playStoreMarketUrl + packageName));
} else {
intent = new Intent(Intent.ACTION_VIEW, Uri.parse(playStoreMarketUrl + packageName));
}
startActivity(intent);
} catch (ActivityNotFoundException e) {
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(playStoreWebUrl + packageName));
startActivity(intent);
}
}

I have combined both Berťák and Stefano Munarini answer to creating a hybrid solution which handles both Rate this App and Show More App scenario.
/**
* This method checks if GooglePlay is installed or not on the device and accordingly handle
* Intents to view for rate App or Publisher's Profile
*
* #param showPublisherProfile pass true if you want to open Publisher Page else pass false to open APp page
* #param publisherID pass Dev ID if you have passed PublisherProfile true
*/
public void openPlayStore(boolean showPublisherProfile, String publisherID) {
//Error Handling
if (publisherID == null || !publisherID.isEmpty()) {
publisherID = "";
//Log and continue
Log.w("openPlayStore Method", "publisherID is invalid");
}
Intent openPlayStoreIntent;
boolean isGooglePlayInstalled = false;
if (showPublisherProfile) {
//Open Publishers Profile on PlayStore
openPlayStoreIntent = new Intent(Intent.ACTION_VIEW,
Uri.parse("market://search?q=pub:" + publisherID));
} else {
//Open this App on PlayStore
openPlayStoreIntent = new Intent(Intent.ACTION_VIEW,
Uri.parse("market://details?id=" + getPackageName()));
}
// find all applications who can handle openPlayStoreIntent
final List<ResolveInfo> otherApps = getPackageManager()
.queryIntentActivities(openPlayStoreIntent, 0);
for (ResolveInfo otherApp : otherApps) {
// look for Google Play application
if (otherApp.activityInfo.applicationInfo.packageName.equals("com.android.vending")) {
ActivityInfo otherAppActivity = otherApp.activityInfo;
ComponentName componentName = new ComponentName(
otherAppActivity.applicationInfo.packageName,
otherAppActivity.name
);
// make sure it does NOT open in the stack of your activity
openPlayStoreIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
// task reparenting if needed
openPlayStoreIntent.addFlags(Intent.FLAG_ACTIVITY_RESET_TASK_IF_NEEDED);
// if the Google Play was already open in a search result
// this make sure it still go to the app page you requested
openPlayStoreIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
// this make sure only the Google Play app is allowed to
// intercept the intent
openPlayStoreIntent.setComponent(componentName);
startActivity(openPlayStoreIntent);
isGooglePlayInstalled = true;
break;
}
}
// if Google Play is not Installed on the device, open web browser
if (!isGooglePlayInstalled) {
Intent webIntent;
if (showPublisherProfile) {
//Open Publishers Profile on web browser
webIntent = new Intent(Intent.ACTION_VIEW,
Uri.parse("http://play.google.com/store/search?q=pub:" + getPackageName()));
} else {
//Open this App on web browser
webIntent = new Intent(Intent.ACTION_VIEW,
Uri.parse("https://play.google.com/store/apps/details?id=" + getPackageName()));
}
startActivity(webIntent);
}
}
Usage
To Open Publishers Profile
#OnClick(R.id.ll_more_apps)
public void showMoreApps() {
openPlayStore(true, "Hitesh Sahu");
}
To Open App Page on PlayStore
#OnClick(R.id.ll_rate_this_app)
public void openAppInPlayStore() {
openPlayStore(false, "");
}

public void launchPlayStore(Context context, String packageName) {
Intent intent = null;
try {
intent = new Intent(Intent.ACTION_VIEW);
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent.setData(Uri.parse("market://details?id=" + packageName));
context.startActivity(intent);
} catch (android.content.ActivityNotFoundException anfe) {
startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("https://play.google.com/store/apps/details?id=" + packageName)));
}
}

My kotlin entension function for this purpose
fun Context.canPerformIntent(intent: Intent): Boolean {
val mgr = this.packageManager
val list = mgr.queryIntentActivities(intent, PackageManager.MATCH_DEFAULT_ONLY)
return list.size > 0
}
And in your activity
val uri = if (canPerformIntent(Intent(Intent.ACTION_VIEW, Uri.parse("market://")))) {
Uri.parse("market://details?id=" + appPackageName)
} else {
Uri.parse("https://play.google.com/store/apps/details?id=" + appPackageName)
}
startActivity(Intent(Intent.ACTION_VIEW, uri))

KOTLIN :
create extension in context.
fun Context.openPlayStoreApp(pkgName:String?){
if(!pkgName.isNullOrEmpty()) {
try {
startActivity(Intent(Intent.ACTION_VIEW, Uri.parse("market://details?id=$pkgName")))
} catch (e: ActivityNotFoundException) {
startActivity(
Intent(
Intent.ACTION_VIEW,
Uri.parse("https://play.google.com/store/apps/details?id=$pkgName")
)
)
}
}
}
Hope it should work.

Peoples, dont forget that you could actually get something more from it. I mean UTM tracking for example. https://developers.google.com/analytics/devguides/collection/android/v4/campaigns
public static final String MODULE_ICON_PACK_FREE = "com.example.iconpack_free";
public static final String APP_STORE_URI =
"market://details?id=%s&referrer=utm_source=%s&utm_medium=app&utm_campaign=plugin";
public static final String APP_STORE_GENERIC_URI =
"https://play.google.com/store/apps/details?id=%s&referrer=utm_source=%s&utm_medium=app&utm_campaign=plugin";
try {
startActivity(new Intent(
Intent.ACTION_VIEW,
Uri.parse(String.format(Locale.US,
APP_STORE_URI,
MODULE_ICON_PACK_FREE,
getPackageName()))).addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP));
} catch (android.content.ActivityNotFoundException anfe) {
startActivity(new Intent(
Intent.ACTION_VIEW,
Uri.parse(String.format(Locale.US,
APP_STORE_GENERIC_URI,
MODULE_ICON_PACK_FREE,
getPackageName()))).addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP));
}

A kotlin verison with fallback and current syntax
fun openAppInPlayStore() {
val uri = Uri.parse("market://details?id=" + context.packageName)
val goToMarketIntent = Intent(Intent.ACTION_VIEW, uri)
var flags = Intent.FLAG_ACTIVITY_NO_HISTORY or Intent.FLAG_ACTIVITY_MULTIPLE_TASK or Intent.FLAG_ACTIVITY_NEW_TASK
flags = if (Build.VERSION.SDK_INT >= 21) {
flags or Intent.FLAG_ACTIVITY_NEW_DOCUMENT
} else {
flags or Intent.FLAG_ACTIVITY_CLEAR_TASK
}
goToMarketIntent.addFlags(flags)
try {
startActivity(context, goToMarketIntent, null)
} catch (e: ActivityNotFoundException) {
val intent = Intent(Intent.ACTION_VIEW,
Uri.parse("http://play.google.com/store/apps/details?id=" + context.packageName))
startActivity(context, intent, null)
}
}

Tested. This should work fine.
val context = LocalContext.current
val onOpenPlayStore: () -> Unit = {
try {
LOG.d(tag, "onOpenPlayStore ${context.packageName}")
val intent = Intent(Intent.ACTION_VIEW, Uri.parse("market://details?id=${context.packageName}"))
startActivity(context, intent, null)
} catch (e: ActivityNotFoundException) {
var intent = Intent(Intent.ACTION_VIEW, Uri.parse("https://play.google.com/store/apps/details?id=${context.packageName}"))
startActivity(context, intent, null)
}
}

For Rate Application: Redirect to Playstore.
In Flutter, you can do it through a Platform channel Like this
Flutter Part:-
static const platform = const MethodChannel('rateApp'); // initialize
onTap: platform.invokeMethod('urls', {'android_id': 'com.xyz'}),
Now Android Native Part(Java):
private static final String RATEAPP = "rateApp"; // initialize variable
// Now in ConfigureFlutterEngine funtion:
new MethodChannel(flutterEngine.getDartExecutor().getBinaryMessenger(), RATEAPP)
.setMethodCallHandler(
(call, result) -> {
if (call.method.equals("urls") && call.hasArgument("android_id")) {
String id = call.argument("android_id").toString();
try {
startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("$uri" + id)));
} catch (android.content.ActivityNotFoundException anfe) {
startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("https://play.google.com/store/apps/details?id=" + id)));
}
result.success("Done");
} else {
result.notImplemented();
}
}
);

How can i Search any web sites without typing http:// or www. (like other android browser's)

try {
ourBrowser.loadUrl("http://google.com");
} catch (Exception e) {
e.printStackTrace();
}
this code is ok i know but how can i search any site without using Http or www ... like other android browser's . example sometime we type Hello and Google give us all hello worlds with link's....... i m new in android world so please developer's help me out....?
i m also tried this method = ourBrowser.loadUrl("http://google.com"+url);

https://www.google.cz/search?q=search+term
is the thing you want or use it as intent:
Uri uri = Uri.parse("http://www.google.com/#q=fish");
Intent intent = new Intent(Intent.ACTION_VIEW, uri);
startActivity(intent);

Maybe it's what you need ?
public void launchUrl(String URL){
Intent browserIntent = new Intent(Intent.ACTION_VIEW,
Uri.parse("https://www.google.fr/webhp?sourceid=chrome-instant&ion=1&espv=2&ie=UTF-8#q="+URL));
startActivity(browserIntent);
}
And you will call it with
launchUrl("MysearchExample");

how to implement Rate Us in android

I have made an application now i want to implement Rate Us feature in it. so for that i have added this code in my app
i = new Intent(Intent.ACTION_VIEW , Uri.parse("market://details?id=com.bet.compny"));
startActivity(i);
break;
but when i click on the button for rate us getting force close. here is my log cat output.
android.content.ActivityNotFoundException: No Activity found to handle Intent {
act=android.intent.action.VIEW dat=market://details?id=com.bet.compny }
Any help would be appretiated.

Idk why you get the Error, but this should actually work. I also do it like this:
startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("market://details?id=" + APP_PNAME)));
But keep in mind that this would crash, if you are testing it on an Emulator/ a device without a play store. So I would suggest you to wrap it in a try and catch

This error occurs when running on a device without the Google PlayStore.
I guess you might be running this on a emulator device which doesn't have Playstore and hence the error.
Implement using try catch as follows:
try{
startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("market://details?id="+getPackageName())));
}
catch (ActivityNotFoundException e){
startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("https://play.google.com/store/apps/details?id="+getPackageName())));
}

I am always using below code which is useful for us:
Intent rateIntent = new Intent(Intent.ACTION_VIEW, Uri.parse("market://details?id=" + context.getPackageName()));
startActivity(rateIntent);
In think it will help full for you.

This is the best way to do it;
Appirater is an android library based off the original Appirater By
Arash Payan Appirater iPhone. The goal is to create a cleanly designed
App Rating prompt that you can drop into any android app that will
help remind your users to review your app on the android Market.
https://github.com/sbstrm/appirater-android

try {
Uri marketUri = Uri.parse("market://details?id=" + getPackageName());
Intent marketIntent = new Intent(Intent.ACTION_VIEW, marketUri);
startActivity(marketIntent);
}catch(ActivityNotFoundException e) {
Uri marketUri = Uri.parse("https://play.google.com/store/apps/details?id=" + getPackageName());
Intent marketIntent = new Intent(Intent.ACTION_VIEW, marketUri);
startActivity(marketIntent);
}

Best and Simple Code
private final String mStoreLink;
Without Activity need context/activity
this.mStoreLink = "market://details?id=" + activity.getPackageName();
Creat a method like this.
public void rateUsOnGooglePlay() {
final Uri marketUri = Uri.parse(mStoreLink);
try {
activity.startActivity(new Intent(Intent.ACTION_VIEW, marketUri));
} catch (android.content.ActivityNotFoundException ex) {
Toast.makeText(activity, "Couldn't find PlayStore on this device", Toast.LENGTH_SHORT).show();
}
}

This commonly happens on a device without the Google Play Store

i think u have test this code in emulator, and emulator have no plastore application, so this error came.
I have implement this and my code is like this.
startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("market://details?id=applicationID of play sotre")));
please put try catch in bellow code.
and try this code in android device.

Uri marketUri = Uri.parse("market://details?id=" + packageName);
Intent marketIntent = new Intent(Intent.ACTION_VIEW, marketUri);
startActivity(marketIntent);

in my case, I wanted the user to click on "MORE BY US" and he would be redirected
to my playstore homepage, but the app was crashing. The reason was simple. I added extra spaces and lines to the link something like below:
<string name = "more_app_link">
playstore.link...............
</string>
then I removed extra lines and spaces like this:
<string name = "more_app_link">playstore.link...............</string>
and it worked very well.

How to open the Google Play Store directly from my Android application?

I have open the Google Play store using the following code
Intent i = new Intent(android.content.Intent.ACTION_VIEW);
i.setData(Uri.parse("https://play.google.com/store/apps/details?id=my packagename "));
startActivity(i);.
But it shows me a Complete Action View as to select the option (browser/play store). I need to open the application in Play Store directly.

You can do this using the market:// prefix.
Java
final String appPackageName = getPackageName(); // getPackageName() from Context or Activity object
try {
startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("market://details?id=" + appPackageName)));
} catch (android.content.ActivityNotFoundException anfe) {
startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("https://play.google.com/store/apps/details?id=" + appPackageName)));
}
Kotlin
try {
startActivity(Intent(Intent.ACTION_VIEW, Uri.parse("market://details?id=$packageName")))
} catch (e: ActivityNotFoundException) {
startActivity(Intent(Intent.ACTION_VIEW, Uri.parse("https://play.google.com/store/apps/details?id=$packageName")))
}
We use a try/catch block here because an Exception will be thrown if the Play Store is not installed on the target device.
NOTE: Any app can register as capable of handling the market://details?id=<appId> URI. If you want to specifically target Google Play, the solution in Berťák's answer is a good alternative.

Many answers here suggest to use Uri.parse("market://details?id=" + appPackageName)) to open Google Play, but I think it is insufficient in fact:
Some third-party applications can use its own intent-filters with "market://" scheme defined, thus they can process supplied Uri instead of Google Play (I experienced this situation with e.g.SnapPea application). The question is "How to open the Google Play Store?", so I assume, that you do not want to open any other application. Please also note, that e.g. app rating is only relevant in GP Store app etc...
To open Google Play AND ONLY Google Play I use this method:
public static void openAppRating(Context context) {
// you can also use BuildConfig.APPLICATION_ID
String appId = context.getPackageName();
Intent rateIntent = new Intent(Intent.ACTION_VIEW,
Uri.parse("market://details?id=" + appId));
boolean marketFound = false;
// find all applications able to handle our rateIntent
final List<ResolveInfo> otherApps = context.getPackageManager()
.queryIntentActivities(rateIntent, 0);
for (ResolveInfo otherApp: otherApps) {
// look for Google Play application
if (otherApp.activityInfo.applicationInfo.packageName
.equals("com.android.vending")) {
ActivityInfo otherAppActivity = otherApp.activityInfo;
ComponentName componentName = new ComponentName(
otherAppActivity.applicationInfo.packageName,
otherAppActivity.name
);
// make sure it does NOT open in the stack of your activity
rateIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
// task reparenting if needed
rateIntent.addFlags(Intent.FLAG_ACTIVITY_RESET_TASK_IF_NEEDED);
// if the Google Play was already open in a search result
// this make sure it still go to the app page you requested
rateIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
// this make sure only the Google Play app is allowed to
// intercept the intent
rateIntent.setComponent(componentName);
context.startActivity(rateIntent);
marketFound = true;
break;
}
}
// if GP not present on device, open web browser
if (!marketFound) {
Intent webIntent = new Intent(Intent.ACTION_VIEW,
Uri.parse("https://play.google.com/store/apps/details?id="+appId));
context.startActivity(webIntent);
}
}
The point is that when more applications beside Google Play can open our intent, app-chooser dialog is skipped and GP app is started directly.
UPDATE:
Sometimes it seems that it opens GP app only, without opening the app's profile. As TrevorWiley suggested in his comment, Intent.FLAG_ACTIVITY_CLEAR_TOP could fix the problem. (I didn't test it myself yet...)
See this answer for understanding what Intent.FLAG_ACTIVITY_RESET_TASK_IF_NEEDED does.

Go on Android Developer official link as tutorial step by step see and got the code for your application package from play store if exists or play store apps not exists then open application from web browser.
Android Developer official link
https://developer.android.com/distribute/tools/promote/linking.html
Linking to a Application Page
From a web site: https://play.google.com/store/apps/details?id=<package_name>
From an Android app: market://details?id=<package_name>
Linking to a Product List
From a web site: https://play.google.com/store/search?q=pub:<publisher_name>
From an Android app: market://search?q=pub:<publisher_name>
Linking to a Search Result
From a web site: https://play.google.com/store/search?q=<search_query>&c=apps
From an Android app: market://search?q=<seach_query>&c=apps

While Eric's answer is correct and Berťák's code also works. I think this combines both more elegantly.
try {
Intent appStoreIntent = new Intent(Intent.ACTION_VIEW, Uri.parse("market://details?id=" + appPackageName));
appStoreIntent.setPackage("com.android.vending");
startActivity(appStoreIntent);
} catch (android.content.ActivityNotFoundException exception) {
startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("https://play.google.com/store/apps/details?id=" + appPackageName)));
}
By using setPackage, you force the device to use the Play Store. If there is no Play Store installed, the Exception will be caught.

try this
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setData(Uri.parse("market://details?id=com.example.android"));
startActivity(intent);

All of the above answers open Google Play in a new view of the same app, if you actually want to open Google Play (or any other app) independently:
Intent launchIntent = getPackageManager().getLaunchIntentForPackage("com.android.vending");
// package name and activity
ComponentName comp = new ComponentName("com.android.vending",
"com.google.android.finsky.activities.LaunchUrlHandlerActivity");
launchIntent.setComponent(comp);
// sample to open facebook app
launchIntent.setData(Uri.parse("market://details?id=com.facebook.katana"));
startActivity(launchIntent);
The important part is that actually opens google play or any other app independently.
Most of what I have seen uses the approach of the other answers and it was not what I needed hopefully this helps somebody.
Regards.

You can check if the Google Play Store app is installed and, if this is the case, you can use the "market://" protocol.
final String my_package_name = "........." // <- HERE YOUR PACKAGE NAME!!
String url = "";
try {
//Check whether Google Play store is installed or not:
this.getPackageManager().getPackageInfo("com.android.vending", 0);
url = "market://details?id=" + my_package_name;
} catch ( final Exception e ) {
url = "https://play.google.com/store/apps/details?id=" + my_package_name;
}
//Open the app page in Google Play store:
final Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_WHEN_TASK_RESET);
startActivity(intent);

use market://
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse("market://details?id=" + my_packagename));

As the official docs use https:// instead of market://, this combines Eric's and M3-n50's answer with code reuse (don't repeat yourself):
Intent intent = new Intent(Intent.ACTION_VIEW)
.setData(Uri.parse("https://play.google.com/store/apps/details?id=" + getPackageName()));
try {
startActivity(new Intent(intent)
.setPackage("com.android.vending"));
} catch (android.content.ActivityNotFoundException exception) {
startActivity(intent);
}
It tries to open with the GPlay app if it exists and falls back to default.

Some of the answers to this question are outdated.
What worked for me (in 2020) was to explicitly tell the intent to skip the chooser and directly open the play store app, according to this link:
"If you want to link to your products from an Android app, create an
Intent that opens a URL. As you configure this intent, pass
"com.android.vending" into Intent.setPackage() so that users see your
app's details in the Google Play Store app instead of a chooser."
This is the Kotlin code I used to direct users to viewing the app containing the package name com.google.android.apps.maps in Google Play:
val intent = Intent(Intent.ACTION_VIEW).apply {
data = Uri.parse("http://play.google.com/store/apps/details?id=com.google.android.apps.maps")
setPackage("com.android.vending")
}
startActivity(intent)
I hope that helps someone!

Kotlin:
Extension:
fun Activity.openAppInGooglePlay(){
val appId = BuildConfig.APPLICATION_ID
try {
this.startActivity(Intent(Intent.ACTION_VIEW, Uri.parse("market://details?id=$appId")))
} catch (anfe: ActivityNotFoundException) {
this.startActivity(
Intent(
Intent.ACTION_VIEW,
Uri.parse("https://play.google.com/store/apps/details?id=$appId")
)
)
}}
Method:
fun openAppInGooglePlay(activity:Activity){
val appId = BuildConfig.APPLICATION_ID
try {
activity.startActivity(Intent(Intent.ACTION_VIEW, Uri.parse("market://details?id=$appId")))
} catch (anfe: ActivityNotFoundException) {
activity.startActivity(
Intent(
Intent.ACTION_VIEW,
Uri.parse("https://play.google.com/store/apps/details?id=$appId")
)
)
}
}

You can do:
final Uri marketUri = Uri.parse("market://details?id=" + packageName);
startActivity(new Intent(Intent.ACTION_VIEW, marketUri));
get Reference here:
You can also try the approach described in the accepted answer of this question:
Cannot determine whether Google play store is installed or not on Android device

Very late in the party Official docs are here. And code described is
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setData(Uri.parse(
"https://play.google.com/store/apps/details?id=com.example.android"));
intent.setPackage("com.android.vending");
startActivity(intent);
As you configure this intent, pass "com.android.vending" into Intent.setPackage() so that users see your app's details in the Google Play Store app instead of a chooser.
for KOTLIN
val intent = Intent(Intent.ACTION_VIEW).apply {
data = Uri.parse(
"https://play.google.com/store/apps/details?id=com.example.android")
setPackage("com.android.vending")
}
startActivity(intent)
If you have published an instant app using Google Play Instant, you can launch the app as follows:
Intent intent = new Intent(Intent.ACTION_VIEW);
Uri.Builder uriBuilder = Uri.parse("https://play.google.com/store/apps/details")
.buildUpon()
.appendQueryParameter("id", "com.example.android")
.appendQueryParameter("launch", "true");
// Optional parameters, such as referrer, are passed onto the launched
// instant app. You can retrieve these parameters using
// Activity.getIntent().getData().
uriBuilder.appendQueryParameter("referrer", "exampleCampaignId");
intent.setData(uriBuilder.build());
intent.setPackage("com.android.vending");
startActivity(intent);
For KOTLIN
val uriBuilder = Uri.parse("https://play.google.com/store/apps/details")
.buildUpon()
.appendQueryParameter("id", "com.example.android")
.appendQueryParameter("launch", "true")
// Optional parameters, such as referrer, are passed onto the launched
// instant app. You can retrieve these parameters using Activity.intent.data.
uriBuilder.appendQueryParameter("referrer", "exampleCampaignId")
val intent = Intent(Intent.ACTION_VIEW).apply {
data = uriBuilder.build()
setPackage("com.android.vending")
}
startActivity(intent)

Ready-to-use solution:
public class GoogleServicesUtils {
public static void openAppInGooglePlay(Context context) {
final String appPackageName = context.getPackageName();
try {
context.startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("market://details?id=" + appPackageName)));
} catch (android.content.ActivityNotFoundException e) { // if there is no Google Play on device
context.startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("https://play.google.com/store/apps/details?id=" + appPackageName)));
}
}
}
Based on Eric's answer.

Kotlin
fun openAppInPlayStore(appPackageName: String) {
try {
startActivity(Intent(Intent.ACTION_VIEW, Uri.parse("market://details?id=$appPackageName")))
} catch (exception: android.content.ActivityNotFoundException) {
startActivity(Intent(Intent.ACTION_VIEW, Uri.parse("https://play.google.com/store/apps/details?id=$appPackageName")))
}
}

This link will open the app automatically in market:// if you are on Android and in browser if you are on PC.
https://play.app.goo.gl/?link=https://play.google.com/store/apps/details?id=com.app.id&ddl=1&pcampaignid=web_ddl_1

If you want to open Google Play store from your app then use this command directy: market://details?gotohome=com.yourAppName, it will open your app's Google Play store pages.
Web: http://play.google.com/store/apps/details?id=
App: market://details?id=
Show all apps by a specific publisher
Web: http://play.google.com/store/search?q=pub:
App: market://search?q=pub:
Search for apps that using the Query on its title or description
Web: http://play.google.com/store/search?q=
App: market://search?q=
Reference: https://tricklio.com/market-details-gotohome-1/

Here is the final code from the answers above that first attempts to open the app using the Google play store app and specifically play store, if it fails, it will start the action view using the web version:
Credits to #Eric, #Jonathan Caballero
public void goToPlayStore() {
String playStoreMarketUrl = "market://details?id=";
String playStoreWebUrl = "https://play.google.com/store/apps/details?id=";
String packageName = getActivity().getPackageName();
try {
Intent intent = getActivity()
.getPackageManager()
.getLaunchIntentForPackage("com.android.vending");
if (intent != null) {
ComponentName androidComponent = new ComponentName("com.android.vending",
"com.google.android.finsky.activities.LaunchUrlHandlerActivity");
intent.setComponent(androidComponent);
intent.setData(Uri.parse(playStoreMarketUrl + packageName));
} else {
intent = new Intent(Intent.ACTION_VIEW, Uri.parse(playStoreMarketUrl + packageName));
}
startActivity(intent);
} catch (ActivityNotFoundException e) {
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(playStoreWebUrl + packageName));
startActivity(intent);
}
}

I have combined both Berťák and Stefano Munarini answer to creating a hybrid solution which handles both Rate this App and Show More App scenario.
/**
* This method checks if GooglePlay is installed or not on the device and accordingly handle
* Intents to view for rate App or Publisher's Profile
*
* #param showPublisherProfile pass true if you want to open Publisher Page else pass false to open APp page

*/
public void openPlayStore(boolean showPublisherProfile, String publisherID) {
//Error Handling
if (publisherID == null || !publisherID.isEmpty()) {
publisherID = "";
//Log and continue
Log.w("openPlayStore Method", "publisherID is invalid");
}
Intent openPlayStoreIntent;
boolean isGooglePlayInstalled = false;
if (showPublisherProfile) {
//Open Publishers Profile on PlayStore
openPlayStoreIntent = new Intent(Intent.ACTION_VIEW,
Uri.parse("market://search?q=pub:" + publisherID));
} else {
//Open this App on PlayStore
openPlayStoreIntent = new Intent(Intent.ACTION_VIEW,
Uri.parse("market://details?id=" + getPackageName()));
}
// find all applications who can handle openPlayStoreIntent
final List<ResolveInfo> otherApps = getPackageManager()
.queryIntentActivities(openPlayStoreIntent, 0);
for (ResolveInfo otherApp : otherApps) {
// look for Google Play application
if (otherApp.activityInfo.applicationInfo.packageName.equals("com.android.vending")) {
ActivityInfo otherAppActivity = otherApp.activityInfo;
ComponentName componentName = new ComponentName(
otherAppActivity.applicationInfo.packageName,
otherAppActivity.name
);
// make sure it does NOT open in the stack of your activity
openPlayStoreIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
// task reparenting if needed
openPlayStoreIntent.addFlags(Intent.FLAG_ACTIVITY_RESET_TASK_IF_NEEDED);
// if the Google Play was already open in a search result
// this make sure it still go to the app page you requested
openPlayStoreIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
// this make sure only the Google Play app is allowed to
// intercept the intent
openPlayStoreIntent.setComponent(componentName);
startActivity(openPlayStoreIntent);
isGooglePlayInstalled = true;
break;
}
}
// if Google Play is not Installed on the device, open web browser
if (!isGooglePlayInstalled) {
Intent webIntent;
if (showPublisherProfile) {
//Open Publishers Profile on web browser
webIntent = new Intent(Intent.ACTION_VIEW,
Uri.parse("http://play.google.com/store/search?q=pub:" + getPackageName()));
} else {
//Open this App on web browser
webIntent = new Intent(Intent.ACTION_VIEW,
Uri.parse("https://play.google.com/store/apps/details?id=" + getPackageName()));
}
startActivity(webIntent);
}
}
Usage
To Open Publishers Profile
#OnClick(R.id.ll_more_apps)
public void showMoreApps() {
openPlayStore(true, "Hitesh Sahu");
}
To Open App Page on PlayStore
#OnClick(R.id.ll_rate_this_app)
public void openAppInPlayStore() {
openPlayStore(false, "");
}

public void launchPlayStore(Context context, String packageName) {
Intent intent = null;
try {
intent = new Intent(Intent.ACTION_VIEW);
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent.setData(Uri.parse("market://details?id=" + packageName));
context.startActivity(intent);
} catch (android.content.ActivityNotFoundException anfe) {
startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("https://play.google.com/store/apps/details?id=" + packageName)));
}
}

My kotlin entension function for this purpose
fun Context.canPerformIntent(intent: Intent): Boolean {
val mgr = this.packageManager
val list = mgr.queryIntentActivities(intent, PackageManager.MATCH_DEFAULT_ONLY)
return list.size > 0
}
And in your activity
val uri = if (canPerformIntent(Intent(Intent.ACTION_VIEW, Uri.parse("market://")))) {
Uri.parse("market://details?id=" + appPackageName)
} else {
Uri.parse("https://play.google.com/store/apps/details?id=" + appPackageName)
}
startActivity(Intent(Intent.ACTION_VIEW, uri))

KOTLIN :
create extension in context.
fun Context.openPlayStoreApp(pkgName:String?){
if(!pkgName.isNullOrEmpty()) {
try {
startActivity(Intent(Intent.ACTION_VIEW, Uri.parse("market://details?id=$pkgName")))
} catch (e: ActivityNotFoundException) {
startActivity(
Intent(
Intent.ACTION_VIEW,
Uri.parse("https://play.google.com/store/apps/details?id=$pkgName")
)
)
}
}
}
Hope it should work.

Peoples, dont forget that you could actually get something more from it. I mean UTM tracking for example. https://developers.google.com/analytics/devguides/collection/android/v4/campaigns
public static final String MODULE_ICON_PACK_FREE = "com.example.iconpack_free";
public static final String APP_STORE_URI =
"market://details?id=%s&referrer=utm_source=%s&utm_medium=app&utm_campaign=plugin";
public static final String APP_STORE_GENERIC_URI =
"https://play.google.com/store/apps/details?id=%s&referrer=utm_source=%s&utm_medium=app&utm_campaign=plugin";
try {
startActivity(new Intent(
Intent.ACTION_VIEW,
Uri.parse(String.format(Locale.US,
APP_STORE_URI,
MODULE_ICON_PACK_FREE,
getPackageName()))).addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP));
} catch (android.content.ActivityNotFoundException anfe) {
startActivity(new Intent(
Intent.ACTION_VIEW,
Uri.parse(String.format(Locale.US,
APP_STORE_GENERIC_URI,
MODULE_ICON_PACK_FREE,
getPackageName()))).addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP));
}

A kotlin verison with fallback and current syntax
fun openAppInPlayStore() {
val uri = Uri.parse("market://details?id=" + context.packageName)
val goToMarketIntent = Intent(Intent.ACTION_VIEW, uri)
var flags = Intent.FLAG_ACTIVITY_NO_HISTORY or Intent.FLAG_ACTIVITY_MULTIPLE_TASK or Intent.FLAG_ACTIVITY_NEW_TASK
flags = if (Build.VERSION.SDK_INT >= 21) {
flags or Intent.FLAG_ACTIVITY_NEW_DOCUMENT
} else {
flags or Intent.FLAG_ACTIVITY_CLEAR_TASK
}
goToMarketIntent.addFlags(flags)
try {
startActivity(context, goToMarketIntent, null)
} catch (e: ActivityNotFoundException) {
val intent = Intent(Intent.ACTION_VIEW,
Uri.parse("http://play.google.com/store/apps/details?id=" + context.packageName))
startActivity(context, intent, null)
}
}

Tested. This should work fine.
val context = LocalContext.current
val onOpenPlayStore: () -> Unit = {
try {
LOG.d(tag, "onOpenPlayStore ${context.packageName}")
val intent = Intent(Intent.ACTION_VIEW, Uri.parse("market://details?id=${context.packageName}"))
startActivity(context, intent, null)
} catch (e: ActivityNotFoundException) {
var intent = Intent(Intent.ACTION_VIEW, Uri.parse("https://play.google.com/store/apps/details?id=${context.packageName}"))
startActivity(context, intent, null)
}
}

For Rate Application: Redirect to Playstore.
In Flutter, you can do it through a Platform channel Like this
Flutter Part:-
static const platform = const MethodChannel('rateApp'); // initialize
onTap: platform.invokeMethod('urls', {'android_id': 'com.xyz'}),
Now Android Native Part(Java):
private static final String RATEAPP = "rateApp"; // initialize variable
// Now in ConfigureFlutterEngine funtion:
new MethodChannel(flutterEngine.getDartExecutor().getBinaryMessenger(), RATEAPP)
.setMethodCallHandler(
(call, result) -> {
if (call.method.equals("urls") && call.hasArgument("android_id")) {
String id = call.argument("android_id").toString();
try {
startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("$uri" + id)));
} catch (android.content.ActivityNotFoundException anfe) {
startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("https://play.google.com/store/apps/details?id=" + id)));
}
result.success("Done");
} else {
result.notImplemented();
}
}
);

Start Google search query from activity - Android

I was wondering if there is an easier way (or any way) to start a Browser with a Google search query. For example user can select a certain word or phrase and click a button and the activity will start the browser with the Google search query.
Thank you.

The Intent class defines an action specifically for web searches:
http://developer.android.com/reference/android/content/Intent.html#ACTION_WEB_SEARCH
Here's an example of how to use it:
Intent intent = new Intent(Intent.ACTION_WEB_SEARCH);
intent.putExtra(SearchManager.QUERY, query); // query contains search string
startActivity(intent);

You can do this quite easily with a few lines of code (assuming you want to search Google for 'fish'):
String escapedQuery = URLEncoder.encode(query, "UTF-8");
Uri uri = Uri.parse("http://www.google.com/#q=" + escapedQuery);
Intent intent = new Intent(Intent.ACTION_VIEW, uri);
startActivity(intent);
Otherwise, if you would rather start up your own Activity to handle the browsing, you should be able to do so with a WebView: http://developer.android.com/reference/android/webkit/WebView.html
I think the better answer here is #zen_of_kermit's. It would be nice though, if Android allowed a user to provide the Search engine has an extra though for the ACTION_WEB_SEARCH, rather than just using Google.

the # gave me trouble:
Uri uri = Uri.parse("https://www.google.com/search?q="+query);
Intent gSearchIntent = new Intent(Intent.ACTION_VIEW, uri);
activity.startActivity(gSearchIntent);

I recently tried this. This appears to work fine. If any modifications to be done let me know as I am new to android development.
mEdit = (EditText)findViewById(R.id.editText);
in your click view,
String q = mEdit.getText().toString();
Intent intent = new Intent(Intent.ACTION_WEB_SEARCH );
intent.putExtra(SearchManager.QUERY, q);
startActivity(intent);

String Search= null;
try {
Search= URLEncoder.encode(s, "UTF-8");
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
}
Uri uri = Uri.parse("http://www.google.com/#q=" + Search);
Intent intent = new Intent(Intent.ACTION_VIEW, uri);
startActivity(intent);
}
});

Starting navigation in Waze with Android's Intents - android

Fix you uri to: String uri = "waze://?ll=40.761043, -73.980545&navigate=yes"; (added navigate=yes) and you should be good.

If this is still relevant you can use this: String uri = "geo: latitude,longtitude"; startActivity(new Intent(android.content.Intent.ACTION_VIEW, Uri.parse(uri)));

Today's Waze base url is https://waze.com/ul so to navigate you have to use https://waze.com/ul?ll=45.6906304,-120.810983&navigate=yes
