I want to launch an installed package from my Android application. I assume that it is possible using intents, but I didn't find a way of doing it. Is there a link, where to find the information?
If you don't know the main activity, then the package name can be used to launch the application.
Intent launchIntent = getPackageManager().getLaunchIntentForPackage("com.package.address");
if (launchIntent != null) {
startActivity(launchIntent);//null pointer check in case package name was not found
}
I know this has been answered but here is how I implemented something similar:
Intent intent = getPackageManager().getLaunchIntentForPackage("com.package.name");
if (intent != null) {
// We found the activity now start the activity
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);
} else {
// Bring user to the market or let them choose an app?
intent = new Intent(Intent.ACTION_VIEW);
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent.setData(Uri.parse("market://details?id=" + "com.package.name"));
startActivity(intent);
}
Even better, here is the method:
public void startNewActivity(Context context, String packageName) {
Intent intent = context.getPackageManager().getLaunchIntentForPackage(packageName);
if (intent != null) {
// We found the activity now start the activity
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(intent);
} else {
// Bring user to the market or let them choose an app?
intent = new Intent(Intent.ACTION_VIEW);
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent.setData(Uri.parse("market://details?id=" + packageName));
context.startActivity(intent);
}
}
Removed duplicate code:
public void startNewActivity(Context context, String packageName) {
Intent intent = context.getPackageManager().getLaunchIntentForPackage(packageName);
if (intent == null) {
// Bring user to the market or let them choose an app?
intent = new Intent(Intent.ACTION_VIEW);
intent.setData(Uri.parse("market://details?id=" + packageName));
}
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(intent);
}
I found the solution. In the manifest file of the application I found the package name: com.package.address and the name of the main activity which I want to launch: MainActivity
The following code starts this application:
Intent intent = new Intent(Intent.ACTION_MAIN);
intent.setComponent(new ComponentName("com.package.address","com.package.address.MainActivity"));
startActivity(intent);
// in onCreate method
String appName = "Gmail";
String packageName = "com.google.android.gm";
openApp(context, appName, packageName);
public static void openApp(Context context, String appName, String packageName) {
if (isAppInstalled(context, packageName))
if (isAppEnabled(context, packageName))
context.startActivity(context.getPackageManager().getLaunchIntentForPackage(packageName));
else Toast.makeText(context, appName + " app is not enabled.", Toast.LENGTH_SHORT).show();
else Toast.makeText(context, appName + " app is not installed.", Toast.LENGTH_SHORT).show();
}
private static boolean isAppInstalled(Context context, String packageName) {
PackageManager pm = context.getPackageManager();
try {
pm.getPackageInfo(packageName, PackageManager.GET_ACTIVITIES);
return true;
} catch (PackageManager.NameNotFoundException ignored) {
}
return false;
}
private static boolean isAppEnabled(Context context, String packageName) {
boolean appStatus = false;
try {
ApplicationInfo ai = context.getPackageManager().getApplicationInfo(packageName, 0);
if (ai != null) {
appStatus = ai.enabled;
}
} catch (PackageManager.NameNotFoundException e) {
e.printStackTrace();
}
return appStatus;
}
Edit depending on comment
In some versions - as suggested in comments - the exception thrown may be different.
Thus the solution below is slightly modified
Intent launchIntent = null;
try{
launchIntent = getPackageManager().getLaunchIntentForPackage("applicationId");
} catch (Exception ignored) {}
if(launchIntent == null){
startActivity(new Intent(Intent.ACTION_VIEW).setData(Uri.parse("https://play.google.com/store/apps/details?id=" + "applicationId")));
} else {
startActivity(launchIntent);
}
Original Answer
Although answered well, there is a pretty simple implementation that handles if the app is not installed. I do it like this
try{
startActivity(getPackageManager().getLaunchIntentForPackage("applicationId"));
} catch (PackageManager.NameNotFoundException e) {
startActivity(new Intent(Intent.ACTION_VIEW).setData(Uri.parse("https://play.google.com/store/apps/details?id=" + "applicationId")));
}
Replace "applicationId" with the package that you want to open such as com.google.maps, etc.
Here is my example of launching bar/QR code scanner from my app if someone finds it useful
Intent intent = new Intent("com.google.zxing.client.android.SCAN");
intent.setPackage("com.google.zxing.client.android");
try
{
startActivityForResult(intent, SCAN_REQUEST_CODE);
}
catch (ActivityNotFoundException e)
{
//implement prompt dialog asking user to download the package
AlertDialog.Builder downloadDialog = new AlertDialog.Builder(this);
downloadDialog.setTitle(stringTitle);
downloadDialog.setMessage(stringMessage);
downloadDialog.setPositiveButton("yes",
new DialogInterface.OnClickListener()
{
public void onClick(DialogInterface dialogInterface, int i)
{
Uri uri = Uri.parse("market://search?q=pname:com.google.zxing.client.android");
Intent intent = new Intent(Intent.ACTION_VIEW, uri);
try
{
myActivity.this.startActivity(intent);
}
catch (ActivityNotFoundException e)
{
Dialogs.this.showAlert("ERROR", "Google Play Market not found!");
}
}
});
downloadDialog.setNegativeButton("no",
new DialogInterface.OnClickListener()
{
public void onClick(DialogInterface dialog, int i)
{
dialog.dismiss();
}
});
downloadDialog.show();
}
If you want to open specific activity of another application we can use this.
Intent intent = new Intent(Intent.ACTION_MAIN, null);
intent.addCategory(Intent.CATEGORY_LAUNCHER);
final ComponentName cn = new ComponentName("com.android.settings", "com.android.settings.fuelgauge.PowerUsageSummary");
intent.setComponent(cn);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
try
{
startActivity(intent)
}catch(ActivityNotFoundException e){
Toast.makeText(context,"Activity Not Found",Toast.LENGTH_SHORT).show()
}
If you must need other application, instead of showing Toast you can show a dialog. Using dialog you can bring the user to Play-Store to download required application.
Check for the app, avoiding any crashes. If the app exists in the phone then it will be launched, otherwise it will search in Google Play. If no Google Play app installed in the phone, it will search in the Google Play Store via browser:
public void onLunchAnotherApp() {
final String appPackageName = getApplicationContext().getPackageName();
Intent intent = getPackageManager().getLaunchIntentForPackage(appPackageName);
if (intent != null) {
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);
} else {
onGoToAnotherInAppStore(intent, appPackageName);
}
}
public void onGoToAnotherInAppStore(Intent intent, String appPackageName) {
try {
intent = new Intent(Intent.ACTION_VIEW);
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent.setData(Uri.parse("market://details?id=" + appPackageName));
startActivity(intent);
} catch (android.content.ActivityNotFoundException anfe) {
intent = new Intent(Intent.ACTION_VIEW);
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent.setData(Uri.parse("http://play.google.com/store/apps/details?id=" + appPackageName));
startActivity(intent);
}
}
Starting from API 30 (Android 11) you can receive nullpointerexception with launchIntentForPackage
val launchIntent: Intent? = activity.packageManager.getLaunchIntentForPackage("com.google.android.gm")
startActivity(launchIntent)
To avoid this you need to add the needed package to the manifest
<queries>
<package android:name="com.google.android.gm" />
</queries>
Here is documentation
https://developer.android.com/training/package-visibility
And the medium article
https://medium.com/androiddevelopers/package-visibility-in-android-11-cc857f221cd9
It is possible to start an app's activity by using Intent.setClassName according to the docs.
An example:
val activityName = "com.google.android.apps.muzei.MuzeiActivity" // target activity name
val packageName = "net.nurik.roman.muzei" // target package's name
val intent = Intent().setClassName(packageName, activityName)
startActivity(intent)
To open it outside the current app, add this flag before starting the intent.
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK)
A related answer here
If you know the data and the action the installed package react on, you simply should add these information to your intent instance before starting it.
If you have access to the AndroidManifest of the other app, you can see all needed information there.
Steps to launch new activity as follows:
1.Get intent for package
2.If intent is null redirect user to playstore
3.If intent is not null open activity
public void launchNewActivity(Context context, String packageName) {
Intent intent = null;
if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.CUPCAKE) {
intent = context.getPackageManager().getLaunchIntentForPackage(packageName);
}
if (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)));
}
} else {
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(intent);
}
}
private fun openOtherApp() {
val sendIntent = packageManager.getLaunchIntentForPackage("org.mab.dhyanaqrscanner")
startActivity(sendIntent)
finishAffinity()
}
This will cover all scenarios
1.Get intent for package
2.If intent is null redirect user to playstore
3.If there is an issue with open playstore, then it opens on the default browser.
var intent = activity!!.packageManager.getLaunchIntentForPackage("com.google.android.youtube")
if (intent == null) {
if (intent == null) {
intent = try {
Intent(Intent.ACTION_VIEW, Uri.parse("market://details?id=com.google.android.youtube"))
} catch (e: Exception) {
Intent(Intent.ACTION_VIEW, Uri.parse("https://play.google.com/store/apps/details?id=com.google.android.youtube"))
}
}
startActivity(intent)
For Android 11 (API level 30) or higher, in AndroidManifest.xml,
<queries>
<package android:name="com.google.android.youtube" />
<package android:name="com.example.app" />
</queries>
Or simply we can allow for all packages (not recommended)
<uses-permission android:name="android.permission.QUERY_ALL_PACKAGES" tools:ignore="QueryAllPackagesPermission" />

Pass the package name and the message you want to show if package isn't installed ;-)
void openApp(String appPackageName,String message){
Intent launchIntent = getPackageManager().getLaunchIntentForPackage(appPackageName);
if (launchIntent != null) {
startActivity(launchIntent);

Since kotlin is becoming very popular these days, I think it's appropriate to provide a simple solution in Kotlin as well.
var launchIntent: Intent? = null
try {
launchIntent = packageManager.getLaunchIntentForPackage("applicationId")
} catch (ignored: Exception) {

I want to open the MiFit app, in the Google Fit Syncronize, but i'm getting erros. How can i open clicking in a button?
Here is my code:
#OnClick(R.id.div_mi_band)
public void miBandIntegration() {
Intent intent = new Intent();
intent.setComponent(new ComponentName("com.xiaomi.hm.health.thirdbind",".thirdbind.ThirdBindActivity"));

Try this.
Intent launchIntent = getPackageManager().getLaunchIntentForPackage("com.xiaomi.hm.health.thirdbind");
if (launchIntent != null) {
startActivity(launchIntent);//null pointer check in case package name was not found
}
Try below:
try{
boolean isAppInstalled = isPackageInstalled(MainActivity.this,"com.xiaomi.hm.health");
if (isAppInstalled) {
Intent navigationIntent = new Intent();
navigationIntent.setPackage("com.xiaomi.hm.health");
startActivity(navigationIntent);
}else{
Toast.makeText(MainActivity.this,"MI Fit is not currently installed",Toast.LENGTH_SHORT).show();
}
}catch (Exception e){
Toast.makeText(MainActivity.this,"MI Fit Application is not currently installed",Toast.LENGTH_SHORT).show();
e.printStackTrace();
}
To Check App is installed or not:
public static boolean isPackageInstalled(Context context, String packageName) {
final PackageManager packageManager = context.getPackageManager();
Intent intent = packageManager.getLaunchIntentForPackage(packageName);
if (intent == null) {
return false;
}
List <ResolveInfo> list = packageManager.queryIntentActivities(intent, PackageManager.MATCH_DEFAULT_ONLY);
return !list.isEmpty();

Change Package name according to need.

I have an app in which i want to redirect user to app link in play store which is working fine, but if play store is not installed in device then i have to redirect user to app link in browser.How can I archive this issue.
code:-
private void startNewActivity(Context context, String packageName) {
Intent intent = context.getPackageManager().getLaunchIntentForPackage(packageName);
if (intent == null) {
// Bring user to the market or let them choose an app?
intent = new Intent(Intent.ACTION_VIEW);
intent.setData(Uri.parse("market://details?id=" + packageName));
Log.e(TAG,"Package name::"+packageName);
}
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(intent);
}
and calling this method in onclick
startNewActivity(mContext, "market://details?id=com.example.something"));
private void startNewActivity(String packageName) {
try {
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setData(Uri.parse("market://details?id=packageName"));
startActivity(intent);
} catch (Exception e) { //google play app is not installed
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setData(Uri.parse("https://play.google.com/store/apps/details?id=packageName"));
startActivity(intent);
}
}
Or you can try like this.
Below mentioned check if app is installed or not.
private boolean appInstalledOrNot(String uri) {
PackageManager pm = getPackageManager();
boolean app_installed;
try {
pm.getPackageInfo(uri, PackageManager.GET_ACTIVITIES);
app_installed = true;
}
catch (PackageManager.NameNotFoundException e) {
app_installed = false;
}
return app_installed;
}
Now check and use alternatives like this.
boolean installed = appInstalledOrNot("Your_Package_Name");
if(installed) {
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setData(Uri.parse("market://details?id=packageName"));
startActivity(intent);
System.out.println("App is already installed on your phone");
} else {
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setData(Uri.parse("https://play.google.com/store/apps/details?id=packageName"));
startActivity(intent);
System.out.println("App is not currently installed on your phone");
}
Here is my function ... just copy and paste ... pass the package you need as parameter
public Intent getShareIntent(String applicationName, #Nullable Uri localImageUri, #Nullable Uri contentToShare, String textToShare) {
Intent intent = new Intent(Intent.ACTION_SEND);
boolean haveTheApp = false;
if(localImageUri != null){
intent.setType("image/*");
}else{
intent.setType("text/plain");
}
List<ResolveInfo> matches = context.getPackageManager().queryIntentActivities(intent, 0);
for (ResolveInfo info : matches) {
if (info.activityInfo.packageName.toLowerCase().contains(applicationName)) {
intent.setPackage(info.activityInfo.packageName);
intent.setClassName(info.activityInfo.packageName, info.activityInfo.name);
if(contentToShare != null){
intent.putExtra(Intent.EXTRA_TEXT, textToShare + ": " + contentToShare.toString());
}else{
intent.putExtra(Intent.EXTRA_TEXT, textToShare + " #App");
}
if(localImageUri != null){
intent.putExtra(Intent.EXTRA_STREAM, localImageUri);
}
haveTheApp = true;
break;
}
}
if(!haveTheApp){
intent = new Intent(Intent.ACTION_VIEW, Uri.parse("market://search?q=" + applicationName));
}
return intent;
}
I want to launch an installed package from my Android application. I assume that it is possible using intents, but I didn't find a way of doing it. Is there a link, where to find the information?
If you don't know the main activity, then the package name can be used to launch the application.
Intent launchIntent = getPackageManager().getLaunchIntentForPackage("com.package.address");
if (launchIntent != null) {
startActivity(launchIntent);//null pointer check in case package name was not found
}
I know this has been answered but here is how I implemented something similar:
Intent intent = getPackageManager().getLaunchIntentForPackage("com.package.name");
if (intent != null) {
// We found the activity now start the activity
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);
} else {
// Bring user to the market or let them choose an app?
intent = new Intent(Intent.ACTION_VIEW);
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent.setData(Uri.parse("market://details?id=" + "com.package.name"));
startActivity(intent);
}
Even better, here is the method:
public void startNewActivity(Context context, String packageName) {
Intent intent = context.getPackageManager().getLaunchIntentForPackage(packageName);
if (intent != null) {
// We found the activity now start the activity
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(intent);
} else {
// Bring user to the market or let them choose an app?
intent = new Intent(Intent.ACTION_VIEW);
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent.setData(Uri.parse("market://details?id=" + packageName));
context.startActivity(intent);
}
}
Removed duplicate code:
public void startNewActivity(Context context, String packageName) {
Intent intent = context.getPackageManager().getLaunchIntentForPackage(packageName);
if (intent == null) {
// Bring user to the market or let them choose an app?
intent = new Intent(Intent.ACTION_VIEW);
intent.setData(Uri.parse("market://details?id=" + packageName));
}
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(intent);
}
I found the solution. In the manifest file of the application I found the package name: com.package.address and the name of the main activity which I want to launch: MainActivity
The following code starts this application:
Intent intent = new Intent(Intent.ACTION_MAIN);
intent.setComponent(new ComponentName("com.package.address","com.package.address.MainActivity"));
startActivity(intent);
// in onCreate method
String appName = "Gmail";
String packageName = "com.google.android.gm";
openApp(context, appName, packageName);
public static void openApp(Context context, String appName, String packageName) {
if (isAppInstalled(context, packageName))
if (isAppEnabled(context, packageName))
context.startActivity(context.getPackageManager().getLaunchIntentForPackage(packageName));
else Toast.makeText(context, appName + " app is not enabled.", Toast.LENGTH_SHORT).show();
else Toast.makeText(context, appName + " app is not installed.", Toast.LENGTH_SHORT).show();
}
private static boolean isAppInstalled(Context context, String packageName) {
PackageManager pm = context.getPackageManager();
try {
pm.getPackageInfo(packageName, PackageManager.GET_ACTIVITIES);
return true;
} catch (PackageManager.NameNotFoundException ignored) {
}
return false;
}
private static boolean isAppEnabled(Context context, String packageName) {
boolean appStatus = false;
try {
ApplicationInfo ai = context.getPackageManager().getApplicationInfo(packageName, 0);
if (ai != null) {
appStatus = ai.enabled;
}
} catch (PackageManager.NameNotFoundException e) {
e.printStackTrace();
}
return appStatus;
}
Edit depending on comment
In some versions - as suggested in comments - the exception thrown may be different.
Thus the solution below is slightly modified
Intent launchIntent = null;
try{
launchIntent = getPackageManager().getLaunchIntentForPackage("applicationId");
} catch (Exception ignored) {}
if(launchIntent == null){
startActivity(new Intent(Intent.ACTION_VIEW).setData(Uri.parse("https://play.google.com/store/apps/details?id=" + "applicationId")));
} else {
startActivity(launchIntent);
}
Original Answer
Although answered well, there is a pretty simple implementation that handles if the app is not installed. I do it like this
try{
startActivity(getPackageManager().getLaunchIntentForPackage("applicationId"));
} catch (PackageManager.NameNotFoundException e) {
startActivity(new Intent(Intent.ACTION_VIEW).setData(Uri.parse("https://play.google.com/store/apps/details?id=" + "applicationId")));
}
Replace "applicationId" with the package that you want to open such as com.google.maps, etc.
Here is my example of launching bar/QR code scanner from my app if someone finds it useful
Intent intent = new Intent("com.google.zxing.client.android.SCAN");
intent.setPackage("com.google.zxing.client.android");
try
{
startActivityForResult(intent, SCAN_REQUEST_CODE);
}
catch (ActivityNotFoundException e)
{
//implement prompt dialog asking user to download the package
AlertDialog.Builder downloadDialog = new AlertDialog.Builder(this);
downloadDialog.setTitle(stringTitle);
downloadDialog.setMessage(stringMessage);
downloadDialog.setPositiveButton("yes",
new DialogInterface.OnClickListener()
{
public void onClick(DialogInterface dialogInterface, int i)
{
Uri uri = Uri.parse("market://search?q=pname:com.google.zxing.client.android");
Intent intent = new Intent(Intent.ACTION_VIEW, uri);
try
{
myActivity.this.startActivity(intent);
}
catch (ActivityNotFoundException e)
{
Dialogs.this.showAlert("ERROR", "Google Play Market not found!");
}
}
});
downloadDialog.setNegativeButton("no",
new DialogInterface.OnClickListener()
{
public void onClick(DialogInterface dialog, int i)
{
dialog.dismiss();
}
});
downloadDialog.show();
}
If you want to open specific activity of another application we can use this.
Intent intent = new Intent(Intent.ACTION_MAIN, null);
intent.addCategory(Intent.CATEGORY_LAUNCHER);
final ComponentName cn = new ComponentName("com.android.settings", "com.android.settings.fuelgauge.PowerUsageSummary");
intent.setComponent(cn);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
try
{
startActivity(intent)
}catch(ActivityNotFoundException e){
Toast.makeText(context,"Activity Not Found",Toast.LENGTH_SHORT).show()
}
If you must need other application, instead of showing Toast you can show a dialog. Using dialog you can bring the user to Play-Store to download required application.
Check for the app, avoiding any crashes. If the app exists in the phone then it will be launched, otherwise it will search in Google Play. If no Google Play app installed in the phone, it will search in the Google Play Store via browser:
public void onLunchAnotherApp() {
final String appPackageName = getApplicationContext().getPackageName();
Intent intent = getPackageManager().getLaunchIntentForPackage(appPackageName);
if (intent != null) {
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);
} else {
onGoToAnotherInAppStore(intent, appPackageName);
}
}
public void onGoToAnotherInAppStore(Intent intent, String appPackageName) {
try {
intent = new Intent(Intent.ACTION_VIEW);
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent.setData(Uri.parse("market://details?id=" + appPackageName));
startActivity(intent);
} catch (android.content.ActivityNotFoundException anfe) {
intent = new Intent(Intent.ACTION_VIEW);
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent.setData(Uri.parse("http://play.google.com/store/apps/details?id=" + appPackageName));
startActivity(intent);
}
}
Starting from API 30 (Android 11) you can receive nullpointerexception with launchIntentForPackage
val launchIntent: Intent? = activity.packageManager.getLaunchIntentForPackage("com.google.android.gm")
startActivity(launchIntent)
To avoid this you need to add the needed package to the manifest
<queries>
<package android:name="com.google.android.gm" />
</queries>
Here is documentation
https://developer.android.com/training/package-visibility
And the medium article
https://medium.com/androiddevelopers/package-visibility-in-android-11-cc857f221cd9
It is possible to start an app's activity by using Intent.setClassName according to the docs.
An example:
val activityName = "com.google.android.apps.muzei.MuzeiActivity" // target activity name
val packageName = "net.nurik.roman.muzei" // target package's name
val intent = Intent().setClassName(packageName, activityName)
startActivity(intent)
To open it outside the current app, add this flag before starting the intent.
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK)
A related answer here
If you know the data and the action the installed package react on, you simply should add these information to your intent instance before starting it.
If you have access to the AndroidManifest of the other app, you can see all needed information there.
Steps to launch new activity as follows:
1.Get intent for package
2.If intent is null redirect user to playstore
3.If intent is not null open activity
public void launchNewActivity(Context context, String packageName) {
Intent intent = null;
if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.CUPCAKE) {
intent = context.getPackageManager().getLaunchIntentForPackage(packageName);
}
if (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)));
}
} else {
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(intent);
}
}
private fun openOtherApp() {
val sendIntent = packageManager.getLaunchIntentForPackage("org.mab.dhyanaqrscanner")
startActivity(sendIntent)
finishAffinity()
}
This will cover all scenarios
1.Get intent for package
2.If intent is null redirect user to playstore
3.If there is an issue with open playstore, then it opens on the default browser.
var intent = activity!!.packageManager.getLaunchIntentForPackage("com.google.android.youtube")
if (intent == null) {
if (intent == null) {
intent = try {
Intent(Intent.ACTION_VIEW, Uri.parse("market://details?id=com.google.android.youtube"))
} catch (e: Exception) {
Intent(Intent.ACTION_VIEW, Uri.parse("https://play.google.com/store/apps/details?id=com.google.android.youtube"))
}
}
startActivity(intent)
For Android 11 (API level 30) or higher, in AndroidManifest.xml,
<queries>
<package android:name="com.google.android.youtube" />
<package android:name="com.example.app" />
</queries>
Or simply we can allow for all packages (not recommended)
<uses-permission android:name="android.permission.QUERY_ALL_PACKAGES" tools:ignore="QueryAllPackagesPermission" />

Declaring package visibility needs
Try code below:
Intent intent = new Intent(Intent.ACTION_MAIN);
intent.setComponent(new ComponentName("package_name", "Class_name"));
if (intent.resolveActivity(getPackageManager()) != null)
{
startActivity(intent);
}
In Kotlin
fun openApplicationOrMarket(packageName: String) {
var intent = requireContext().packageManager.getLaunchIntentForPackage(packageName)
if (intent == null) {
intent = Intent(Intent.ACTION_VIEW)
intent.data = Uri.parse("market://details?id=$packageName")
}
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK)
requireContext().startActivity(intent)
}
Pass the package name and the message you want to show if package isn't installed ;-)
void openApp(String appPackageName,String message){
Intent launchIntent = getPackageManager().getLaunchIntentForPackage(appPackageName);
if (launchIntent != null) {
startActivity(launchIntent);
} else {
Toast.makeText(MainActivity.this, message, Toast.LENGTH_LONG).show();
startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("https://play.google.com/store/apps/details?id=" + appPackageName)));
}
}
Since kotlin is becoming very popular these days, I think it's appropriate to provide a simple solution in Kotlin as well.
var launchIntent: Intent? = null
try {
launchIntent = packageManager.getLaunchIntentForPackage("applicationId")
} catch (ignored: Exception) {
}
if (launchIntent == null) {
startActivity(Intent(Intent.ACTION_VIEW).setData(Uri.parse("https://play.google.com/store/apps/details?id=" + "applicationId")))
} else {
startActivity(launchIntent)
}
I would like to make android button and able to launch other application if already installed and go to android market if not yet installed.
How to do this?
Regards,
Virak
use below code
String packageName = "app_package_name";
Intent intent = getPackageManager().getLaunchIntentForPackage(packageName);
if(intent == null) {
intent = new Intent(Intent.ACTION_VIEW, Uri.parse("market://details?id="+packageName));
}
startActivity(intent);
Try with this -
Just create one Button in your layout. And, onClick of that button check below condition -
Button calculateButton = (Button) findViewById(R.id.buttonCalculate);
calculateButton.setOnClickListener(new View.OnClickListener() {
public void onClick(View v)
{
if(check() == true)
{
PackageManager pack = this.getPackageManager();
Intent app = pack.getLaunchIntentForPackage(packagename);
startActivity(app);
}else
{
Intent marketIntent = new Intent(Intent.ACTION_VIEW);
marketIntent.setData(Uri.parse("market://details?id=packagename"));
startActivity(marketIntent);
}
}
});
}
public boolean check()
{
try{
ApplicationInfo info = getPackageManager().getApplicationInfo("packagename", 0 );
return true;
} catch( PackageManager.NameNotFoundException e ){
return false;
}
}
Try to call the Application activity from your code using the, other application package name and activity name or by the Intent filters which is belongs to that other application you need to call...
Intent newIntent;
newIntent = new Intent("other application Package name","class name");
startActivity(newIntent);
Check whether it is launched or not.
//If it is launched, don't do anything
//If it isn't, then navigate the UI to Google Play Intent.
Intent googlePlay = new Intent(Intent.ACTION_VIEW);
googlePlay.setData(Uri.parse("market://details?id="+"other application package name"));
startActivity(googlePlay);
inside onclick
#Override
public void onClick(View view){
try{
startActivity(getPackageManager().getLaunchIntentForPackage("applicationId"));
} catch (PackageManager.NameNotFoundException e) {
startActivity(new Intent(Intent.ACTION_VIEW).setData(Uri.parse("https://play.google.com/store/apps/details?id=" + "applicationId")));
}
}
