How to ask user to enable GPS at the launch of application?

Question

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);
}
}

see the Logcat

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

If you are willing to use Google Play Services, `SettingsApi` has some options for prompting the user to enable locations. [This sample app](https://github.com/commonsguy/cw-omnibus/tree/v8.5/Location/FusedPeriodic) demonstrates the technique. Otherwise, what you want is not possible. — CommonsWare, Apr 20 '17 at 11:45

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 a Task 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;
    } 
}

This is the kotlin implementation of @Ananth answer

Image of GPS permission like Google Maps

If you want to ask permission like shown in the above link, you can refer to my answer: https://stackoverflow.com/a/64757407/10618364

Code is written with GoogleApi and SettingsClient API, not with deprecated GoogleClientApi and SettingsApi.

It is also compatible with Android 11. ;)
