I am using below code to get directions to a particular lat & lng using google api. But I have not used the api key. This app which I am making will soon be pushed to playstore. I just want to make sure what I am doing here is correct or will it cause any problem for me ?
Thanks in advance :)
if (pc.getLatitude() != null && pc.getLongitude() != null) {
double latitude = Double.parseDouble(pc.getLatitude());
double longitude = Double.parseDouble(pc.getLongitude());
String uri = String.format(Locale.ENGLISH, "http://maps.google.com/maps?daddr=%f,%f (%s)", latitude, longitude, "Location");
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(uri));
intent.setClassName("com.google.android.apps.maps", "com.google.android.maps.MapsActivity");
if (intent.resolveActivity(mContext.getPackageManager()) != null) {
Toast.makeText(mContext, R.string.toast_opening_google_maps, Toast.LENGTH_SHORT).show();
mContext.startActivity(intent);
} else {
Toast.makeText(mContext, R.string.toast_no_google_maps_warning, Toast.LENGTH_SHORT).show();
}
} else {
Toast.makeText(mContext, R.string.toast_no_ll_warning, Toast.LENGTH_LONG).show();
}
This is one more example of my api usage
String distanceUrl = "http://maps.googleapis.com/maps/api/distancematrix/json?" +
"origins=" + mOriginLatLng.latitude + "," + mOriginLatLng.longitude +
"&destinations=" + destination.latitude + "," + destination.longitude +
"&mode=driving&language=en-EN&sensor=false";
According to the documentation, you don't need an API key to launch Google Maps using an Intent.
According to the documentation, you will need an API key to use the Distance Matrix API.

I am developing an android app where a customer requests a worker for pickuplocation, so i am using google direction library to show routes between the customer and worker but direction API keeps throwing error saying that you must use an API key to make requests to google cloud platform, already i have created a project in google cloud console and generated my key.
Here is what i have done;
First of all i started my project without a billing account, then in the process of my project i was required to create a billing account in order to make direction request so i linked my project what
What i did;
i added my API key to manifest
i have already enabled places API and direction API
in the direction part i am using google direction library, this one
i added it to app build-gradle
compile 'com.github.jd-alexander:library:1.1.0'
and here is a sample of code in my activity for direction request since i am using the above library i dont know whether it is because i created the project then billing account, what might be the problem?
Even places API does not function properly
private void getRouteToMarker(LatLng customerpickuplocation) {
Routing routing = new Routing.Builder()
.travelMode(AbstractRouting.TravelMode.DRIVING)
.withListener(this)
.alternativeRoutes(false)
.waypoints(new LatLng(lat, lng), customerpickuplocation)
.build();
routing.execute();
}
#Override
public void onRoutingFailure(RouteException e) {
if (e != null) {
Toast.makeText(this, "Error: " + e.getMessage(), Toast.LENGTH_LONG).show();
} else {
Toast.makeText(this, "Something went wrong, Try again", Toast.LENGTH_SHORT).show();
}
}
#Override
public void onRoutingSuccess(ArrayList<Route> route, int shortestRouteIndex) {
if (polylines.size() > 0) {
for (Polyline poly : polylines) {
poly.remove();
}
}
polylines = new ArrayList<>();
//add route(s) to the map.
for (int i = 0; i < route.size(); i++) {
//In case of more than 5 alternative routes
int colorIndex = i % COLORS.length;
PolylineOptions polyOptions = new PolylineOptions();
polyOptions.color(getResources().getColor(COLORS[colorIndex]));
polyOptions.width(10 + i * 3);
polyOptions.addAll(route.get(i).getPoints());
Polyline polyline = mMap.addPolyline(polyOptions);
polylines.add(polyline);
Toast.makeText(getApplicationContext(), "Route " + (i + 1) + ": distance - " + route.get(i).getDistanceValue() + ": duration - " + route.get(i).getDurationValue(), Toast.LENGTH_SHORT).show();
}
}
i have come up with a solution but not a good security measure, by adding key to getRouteToMarker() method
private void getRouteToMarker(LatLng customerpickuplocation) {
Routing routing = new Routing.Builder()
.travelMode(AbstractRouting.TravelMode.DRIVING)
.withListener(this)
.alternativeRoutes(false)
.waypoints(new LatLng(lat, lng), customerpickuplocation)
.key("your api key")
.build();
routing.execute();
}
I am working on android application in which i am using a logic to find the direction of a person from coordinated. Everything is working fine but i got error at console: : "Dead Code". My code is given below, please explain me this thing.
private void direction() {
String userLocation = mLatitude + ","
+ mLongitude ;
if(userLocation!=null){
String distLocation = Constants.sMY_LOCATION.getLatitude() + ","
+ Constants.sMY_LOCATION.getLongitude();
String url = "https://maps.google.com/maps?f=d&saddr=" + userLocation
+ "&daddr=" + distLocation;
Intent i = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
startActivity(i);
}else{ // Getting Dead Code Yellow error here
finish();
Toast.makeText(getBaseContext(), "Please check your internet and try again!", Toast.LENGTH_SHORT).show();
}
}
It's because your else can't be reached
String userLocation = mLatitude + ","
+ mLongitude ;
if(userLocation!=null){
...
}else{
...
}
userLocation will never be null
The code in your else{} will never be reached because your string userLocation is initialized before the if statement, meaning it will never be null.
So the code in you else is effectively dead code.
You should check mLatitude and mLongitude for being null instead of whole String.
Example:
if (mLatitude != null && mLongitude != null) {
// String userLocation = ...
}
else {
// Your else code
}
I am writing a functionality that needs to open a URL either in the another app [if installed in my phone] or else, in the browser.
To open the URL in browser, I can use Titanium.Platefor.openURL();
To open the app I am creating the intent.
var intent = Titanium.Android.createIntent({
packageName : appUrl,
action : Titanium.Android.ACTION_SEND,
data : url
});
intent.addCategory(Titanium.Android.CATEGORY_BROWSABLE);
Titanium.Android.currentActivity.startActivity(intent);
I have stuck in below things:
How to pass the url to other app to open - I tried passing url using url : 'http://someurl' and data: 'http://someurl' - but didn't help. I got the error: No Activity found to handle Intent
How to find out whether the app is install or not? If yes - ask for the application to open, if no - open the url in browser.
Can anyone help?
Thanks in advance!
You can identify app is install or not using URL schema with Titanium.Platefor.openURL(); method in android. (if app is not installed it will return false).
and for ios there is one method for identify Titanium.Platform.canOpenURL().
and also you can passed something value to application for example if you open google map application with source and destination lat long in ios then call like this
var strUrl = "http://maps.google.com/maps?saddr=" + Alloy.Globals.UserLocation.latitude + "," + Alloy.Globals.UserLocation.longitude + "&daddr=" + dLatitude + "," + dLongitude;
if (OS_IOS) {
strUrl = "comgooglemaps://?saddr=" + Alloy.Globals.UserLocation.latitude + "," + Alloy.Globals.UserLocation.longitude + "&daddr=" + dLatitude + "," + dLongitude + "&directionsmode=driving";
if (Titanium.Platform.canOpenURL(strUrl)) {
Ti.Platform.openURL(strUrl);
} else {
strUrl = "http://maps.google.com/maps?saddr=" + Alloy.Globals.UserLocation.latitude + "," + Alloy.Globals.UserLocation.longitude + "&daddr=" + dLatitude + "," + dLongitude;
Ti.Platform.openURL(strUrl);
}
} else {
var result = Ti.Platform.openURL(strUrl);
Ti.API.info('RESULT = ' + result);
}
one more example.. if you want opening whatsApp application with given message text.
var whatsappUrl = encodeURI('whatsapp://send?text=' + msgBody);
if (OS_IOS) {
if (Ti.Platform.canOpenURL(whatsappUrl)) {
Ti.Platform.openURL(whatsappUrl);
} else {
Ti.Platform.openURL("https://itunes.apple.com/ae/app/whatsapp-messenger/id310633997?mt=8");
}
} else {
var isSuccess = Ti.Platform.openURL(whatsappUrl);
if (!isSuccess) {
Ti.Platform.openURL("https://play.google.com/store/apps/details?id=com.whatsapp&hl=en");
}
}
Hop this is helps you.. :)
Thanks
My question is this:
How can I share the location of a marker I place on the map via touch position(Google Maps V2) I have an info window and can see the lat long. I tried and tried to set a button on the map to send the location of the placed marker, and I just can't get it to work.
Please help me to solve this issue.
Here is the code logic I have used:
public void setSendButton(Button sendButton) {
sendButton = (Button) findViewById(R.layout.mymap);}
public void onClick(View v, String Location) {
Context context = getApplicationContext();
SharedPreferences settings = PreferenceManager.getDefaultSharedPreferences(context);
if (googleMap.getMyLocation() != null) {
googleMap.getMyLocation();
}
Intent i = new Intent(android.content.Intent.ACTION_SEND);
Location = location.getLatitude() / 1E6 + "," + location.getLongitude() / 1E6;
i.setType("text/plain");
i.putExtra(Intent.EXTRA_SUBJECT, settings.getString("message_subject", getString(R.string.share_location_subject)));
i.putExtra(Intent.EXTRA_TEXT, settings.getString("message_body", getString(R.string.share_location_body))
+ " http://maps.google.com/maps?q=loc:"
+ location);
try {
startActivity(Intent.createChooser(i, getString(R.string.share_title)));
} catch (android.content.ActivityNotFoundException ex) {
Toast.makeText(context, getString(R.string.no_way_to_share), Toast.LENGTH_LONG).show();
}
Observation and Answer was correct code was just static via misplaced logic. Turns out I did not need a button.
Lesson is just use the objects methods.
Thanks to all.

How to get the location or address from the google map when i am click on a particular address. IS it possible to use map overlay to collect the address from the map view.
Please Use below code for get address.
try {
Geocoder geo = new Geocoder(youractivityclassname.this.getApplicationContext(), Locale.getDefault());
List<Address> addresses = geo.getFromLocation(latitude, longitude, 1);
if (addresses.isEmpty()) {
yourtextfieldname.setText("Waiting for Location");
}
else {
if (addresses.size() > 0) {
yourtextfieldname.setText(addresses.get(0).getFeatureName() + ", " + addresses.get(0).getLocality() +", " + addresses.get(0).getAdminArea() + ", " + addresses.get(0).getCountryName());
//Toast.makeText(getApplicationContext(), "Address:- " + addresses.get(0).getFeatureName() + addresses.get(0).getAdminArea() + addresses.get(0).getLocality(), Toast.LENGTH_LONG).show();
}
}
}
catch (Exception e) {
e.printStackTrace(); // getFromLocation() may sometimes fail
}
And see below link for more information and complete example.
