How to enable Location access programmatically in android?

I am working on map related android application and I need to check location access enable or not in client side development if location services is not enable show the dialog prompt.

How to enable "Location access" Programmatically in android?

Solution 1:

Use below code to check. If it is disabled, dialog box will be generated

public void statusCheck() {
    final LocationManager manager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);

    if (!manager.isProviderEnabled(LocationManager.GPS_PROVIDER)) {
        buildAlertMessageNoGps();

    }
}

private void buildAlertMessageNoGps() {
    final AlertDialog.Builder builder = new AlertDialog.Builder(this);
    builder.setMessage("Your GPS seems to be disabled, do you want to enable it?")
            .setCancelable(false)
            .setPositiveButton("Yes", new DialogInterface.OnClickListener() {
                public void onClick(final DialogInterface dialog, final int id) {
                    startActivity(new Intent(android.provider.Settings.ACTION_LOCATION_SOURCE_SETTINGS));
                }
            })
            .setNegativeButton("No", new DialogInterface.OnClickListener() {
                public void onClick(final DialogInterface dialog, final int id) {
                    dialog.cancel();
                }
            });
    final AlertDialog alert = builder.create();
    alert.show();
}

Solution 2:

Here is a simple way of programmatically enabling location like Maps app:

protected void enableLocationSettings() {
       LocationRequest locationRequest = LocationRequest.create()
             .setInterval(LOCATION_UPDATE_INTERVAL)
             .setFastestInterval(LOCATION_UPDATE_FASTEST_INTERVAL)
             .setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);

        LocationSettingsRequest.Builder builder = new LocationSettingsRequest.Builder()
                .addLocationRequest(locationRequest);

        LocationServices
                .getSettingsClient(this)
                .checkLocationSettings(builder.build())
                .addOnSuccessListener(this, (LocationSettingsResponse response) -> {
                    // startUpdatingLocation(...);
                })
                .addOnFailureListener(this, ex -> {
                    if (ex instanceof ResolvableApiException) {
                        // Location settings are NOT satisfied,  but this can be fixed  by showing the user a dialog.
                        try {
                            // Show the dialog by calling startResolutionForResult(),  and check the result in onActivityResult().
                            ResolvableApiException resolvable = (ResolvableApiException) ex;
                            resolvable.startResolutionForResult(TrackingListActivity.this, REQUEST_CODE_CHECK_SETTINGS);
                        } catch (IntentSender.SendIntentException sendEx) {
                            // Ignore the error.
                        }
                    }
                });
 }

And onActivityResult:

@Override
protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {
    if (REQUEST_CODE_CHECK_SETTINGS == requestCode) {
        if(Activity.RESULT_OK == resultCode){
            //user clicked OK, you can startUpdatingLocation(...);

        }else{
            //user clicked cancel: informUserImportanceOfLocationAndPresentRequestAgain();
        }
    }
}
