How to enable Location access programmatically in android?

Question

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?

Answer 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();
}

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();
        }
    }
}

You can see the documentation here: https://developer.android.com/training/location/change-location-settings

Answer 3

You can try these methods below:

To check if GPS and network provider is enabled:

public boolean canGetLocation() {
    boolean result = true;
    LocationManager lm;
    boolean gpsEnabled = false;
    boolean networkEnabled = false;

    lm = (LocationManager) getSystemService(Context.LOCATION_SERVICE);

    // exceptions will be thrown if provider is not permitted.
    try {
        gpsEnabled = lm.isProviderEnabled(LocationManager.GPS_PROVIDER);
    } catch (Exception ex) {
    }

    try {
        networkEnabled = lm
                .isProviderEnabled(LocationManager.NETWORK_PROVIDER);
    } catch (Exception ex) {
    }

    return gpsEnabled && networkEnabled;
}

Alert Dialog if the above code returns false:

public void showSettingsAlert() {
    AlertDialog.Builder alertDialog = new AlertDialog.Builder(this);

    // Setting Dialog Title
    alertDialog.setTitle("Error!");

    // Setting Dialog Message
    alertDialog.setMessage("Please ");

    // On pressing Settings button
    alertDialog.setPositiveButton(
            getResources().getString(R.string.button_ok),
            new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int which) {
                    Intent intent = new Intent(
                            Settings.ACTION_LOCATION_SOURCE_SETTINGS);
                    startActivity(intent);
                }
            });

    alertDialog.show();
}

How to use the two methods above:

if (canGetLocation()) {     
    //DO SOMETHING USEFUL HERE. ALL GPS PROVIDERS ARE CURRENTLY ENABLED                 
} else {
    //SHOW OUR SETTINGS ALERT, AND LET THE USE TURN ON ALL THE GPS PROVIDERS                                
    showSettingsAlert();
}

Answer 4

just checkout the following thread: How to check if Location Services are enabled? It provides a pretty good example of how to check whether the location service was enabled or not.

Answer 5

private ActivityResultLauncher<IntentSenderRequest> resolutionForResult;

resolutionForResult = registerForActivityResult(new ActivityResultContracts.StartIntentSenderForResult(), result -> {
        if(result.getResultCode() == RESULT_OK){
            //Granted
        }else {
            //Not Granted
        }
    });

    private void enableLocationSettings() {
    LocationRequest locationRequest = LocationRequest.create()
            .setInterval(10 * 1000)
            .setFastestInterval(2 * 1000)
            .setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);

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

    LocationServices
            .getSettingsClient(requireActivity())
            .checkLocationSettings(builder.build())
            .addOnSuccessListener(requireActivity(), (LocationSettingsResponse response) -> {
                // startUpdatingLocation(...);
            })
            .addOnFailureListener(requireActivity(), ex -> {
                if (ex instanceof ResolvableApiException) {
                    try{
                        IntentSenderRequest intentSenderRequest = new IntentSenderRequest.Builder(((ResolvableApiException) ex).getResolution()).build();
                        resolutionForResult.launch(intentSenderRequest);
                    }catch (Exception exception){
                        Log.d(TAG, "enableLocationSettings: "+exception);
                    }
                }
            });
}

Answer 6

With recent Marshmallow update, even when the Location setting is turned on, your app will require to explicitly ask for permission. The recommended way to do this is to show the Permissions section of your app wherein the user can toggle the permission as required. The code snippet for doing this is as below:

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
    
    if (this.checkSelfPermission(Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
    
        final AlertDialog.Builder builder = new AlertDialog.Builder(this);
        builder.setTitle("Location Permission");
        builder.setMessage("The app needs location permissions. Please grant this permission to continue using the features of the app.");
        builder.setPositiveButton(android.R.string.yes, new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialogInterface, int i) {
                requestPermissions(new String[]{Manifest.permission.ACCESS_COARSE_LOCATION}, PERMISSION_REQUEST_COARSE_LOCATION);
    
            }
        });
        builder.setNegativeButton(android.R.string.no, null);
        builder.show();
    }
} else {
    LocationManager locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
    boolean isGpsProviderEnabled, isNetworkProviderEnabled;
    isGpsProviderEnabled = locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER);
    isNetworkProviderEnabled = locationManager.isProviderEnabled(LocationManager.NETWORK_PROVIDER);

    if(!isGpsProviderEnabled && !isNetworkProviderEnabled) {
        final AlertDialog.Builder builder = new AlertDialog.Builder(this);
        builder.setTitle("Location Permission");
        builder.setMessage("The app needs location permissions. Please grant this permission to continue using the features of the app.");
        builder.setPositiveButton(android.R.string.yes, new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialogInterface, int i) {
                Intent intent = new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS);
                startActivity(intent);
            }
        });
        builder.setNegativeButton(android.R.string.no, null);
        builder.show();
    }
}

And override the onRequestPermissionsResult method as below:

@Override
public void onRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults) {
    switch (requestCode) {
        case PERMISSION_REQUEST_COARSE_LOCATION: {
            if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                Log.d(TAG, "coarse location permission granted");
            } else {
                Intent intent = new Intent();
                intent.setAction(Settings.ACTION_APPLICATION_DETAILS_SETTINGS);
                Uri uri = Uri.fromParts("package", getPackageName(), null);
                intent.setData(uri);
                startActivity(intent);
            }
        }
    }
}

Another approach is you can also use the SettingsApi to inquire which location provider(s) are enabled. If none is enabled, you can prompt a dialog to change the setting from within the app.

Answer 7

Taking the answer above and converting it to Kotlin

fun isLocationEnabled(): Boolean {
    val lm = getSystemService(LOCATION_SERVICE) as LocationManager
    // exceptions will be thrown if provider is not permitted.
    val gpsEnabled = try {
        lm.isProviderEnabled(LocationManager.GPS_PROVIDER)
    } catch (ex: java.lang.Exception) {
        false
    }
    val networkEnabled = try {
        lm.isProviderEnabled(LocationManager.NETWORK_PROVIDER)
    } catch (ex: java.lang.Exception) {
        false
    }
    return gpsEnabled && networkEnabled
}
