How to ask user to enable GPS at the launch of application?
Solution 1
If you want something as shown in below image, follow along.
-
Add the following dependencies in your app
build.gradle
implementation 'com.google.android.gms:play-services-location:16.0.0'
-
Create the type of location request you want, we want high accuracy for GPS
LocationRequest locationRequest = LocationRequest.create(); locationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY); LocationSettingsRequest.Builder builder = new LocationSettingsRequest.Builder() .addLocationRequest(locationRequest);
-
Now we need to check current state of GPS. For this, we have to use
LocationServices.getSettingsClient(getActivity()).checkLocationSettings(builder.build())
This will return aTask
which needs to handled asynchronously. In RESOLUTION_REQUIRED case, we ask user to give permissions, this is where we show the user prompt to enable GPS.Task<LocationSettingsResponse> result = LocationServices.getSettingsClient(getActivity()).checkLocationSettings(builder.build()); result.addOnCompleteListener(new OnCompleteListener<LocationSettingsResponse>() { @Override public void onComplete(@NonNull Task<LocationSettingsResponse> task) { try { LocationSettingsResponse response = task.getResult(ApiException.class); // All location settings are satisfied. The client can initialize location // requests here. } catch (ApiException exception) { switch (exception.getStatusCode()) { case LocationSettingsStatusCodes.RESOLUTION_REQUIRED: // Location settings are not satisfied. But could be fixed by showing the // user a dialog. try { // Cast to a resolvable exception. ResolvableApiException resolvable = (ResolvableApiException) exception; // Show the dialog by calling startResolutionForResult(), // and check the result in onActivityResult(). resolvable.startResolutionForResult( getActivity(), LocationRequest.PRIORITY_HIGH_ACCURACY); } catch (IntentSender.SendIntentException e) { // Ignore the error. } catch (ClassCastException e) { // Ignore, should be an impossible error. } break; case LocationSettingsStatusCodes.SETTINGS_CHANGE_UNAVAILABLE: // Location settings are not satisfied. However, we have no way to fix the // settings so we won't show the dialog. break; } } } });
-
Now that we have asked user to turn on GPS, we need to check whether user allowed it or ignored it. For this, override onActivityResult. Please note that, if you're implementing above code in a fragment, result will be received in the enclosing Activity. So override onActivityResult in the Activity class.
@Override public void onActivityResult(int requestCode, int resultCode, Intent data) { switch (requestCode) { case LocationRequest.PRIORITY_HIGH_ACCURACY: switch (resultCode) { case Activity.RESULT_OK: // All required changes were successfully made Log.i(TAG, "onActivityResult: GPS Enabled by user"); break; case Activity.RESULT_CANCELED: // The user was asked to change settings, but chose not to Log.i(TAG, "onActivityResult: User rejected GPS request"); break; default: break; } break; } }
Solution 2
This is the kotlin implementation of @Ananth answer
private fun showLocationPrompt() {
val locationRequest = LocationRequest.create()
locationRequest.priority = LocationRequest.PRIORITY_HIGH_ACCURACY
val builder = LocationSettingsRequest.Builder().addLocationRequest(locationRequest)
val result: Task<LocationSettingsResponse> = LocationServices.getSettingsClient(activity).checkLocationSettings(builder.build())
result.addOnCompleteListener { task ->
try {
val response = task.getResult(ApiException::class.java)
// All location settings are satisfied. The client can initialize location
// requests here.
} catch (exception: ApiException) {
when (exception.statusCode) {
LocationSettingsStatusCodes.RESOLUTION_REQUIRED -> {
try {
// Cast to a resolvable exception.
val resolvable: ResolvableApiException = exception as ResolvableApiException
// Show the dialog by calling startResolutionForResult(),
// and check the result in onActivityResult().
resolvable.startResolutionForResult(
activity, LocationRequest.PRIORITY_HIGH_ACCURACY
)
} catch (e: IntentSender.SendIntentException) {
// Ignore the error.
} catch (e: ClassCastException) {
// Ignore, should be an impossible error.
}
}
LocationSettingsStatusCodes.SETTINGS_CHANGE_UNAVAILABLE -> {
// Location settings are not satisfied. But could be fixed by showing the
// user a dialog.
// Location settings are not satisfied. However, we have no way to fix the
// settings so we won't show the dialog.
}
}
}
}
}
override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
super.onActivityResult(requestCode, resultCode, data)
when (requestCode) {
LocationRequest.PRIORITY_HIGH_ACCURACY -> {
if (resultCode == Activity.RESULT_OK) {
Log.e("Status: ","On")
} else {
Log.e("Status: ","Off")
}
}
}
}

use SettingsApi if you not want to force user to go settings page to enable gps. here the link of how to use SettingsApi SettingsApi

private void turnGPSOn(){ String provider = Settings.Secure.getString(getContentResolver(), Settings.Secure.LOCATION_PROVIDERS_ALLOWED); if(!provider.contains("gps")){ //if gps is disabled final Intent poke = new Intent(); poke.setClassName("com.android.settings", "com.android.settings.widget.SettingsAppWidgetProvider"); poke.addCategory(Intent.CATEGORY_ALTERNATIVE); poke.setData(Uri.parse("3")); sendBroadcast(poke); } }

I tried many other option like package manager, location manager, etc but not able to do what I want. I want that at the launch application user will be prompted to enable the GPS. I don't want user to go inside the settings.
And that I wanted for the API level >=19.
Please help me to solve my problem......... Thanks

CommonsWare about 7 yearsThe question has 'I don't want user to go inside the settings."
-
Arsalan Khan about 7 yearsNo, final decision rely on user either GPS on or off
-
Arsalan Khan about 7 yearsyou prompt this dialog until GPS on

Ananth about 5 yearsThis has been deprecated.
