How to Enable Location Access Programmatically in Android

How to enable Location access programmatically in android?

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();
}

How can I enable or disable the GPS programmatically on Android?

the GPS can be toggled by exploiting a bug in the power manager widget. see this xda thread for discussion.

here's some example code i use

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);
    }
}

private void turnGPSOff(){
    String provider = Settings.Secure.getString(getContentResolver(), Settings.Secure.LOCATION_PROVIDERS_ALLOWED);

    if(provider.contains("gps")){ //if gps is enabled
        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);
    }
}

use the following to test if the existing version of the power control widget is one which will allow you to toggle the gps.

private boolean canToggleGPS() {
    PackageManager pacman = getPackageManager();
    PackageInfo pacInfo = null;

    try {
        pacInfo = pacman.getPackageInfo("com.android.settings", PackageManager.GET_RECEIVERS);
    } catch (NameNotFoundException e) {
        return false; //package not found
    }

    if(pacInfo != null){
        for(ActivityInfo actInfo : pacInfo.receivers){
            //test if recevier is exported. if so, we can toggle GPS.
            if(actInfo.name.equals("com.android.settings.widget.SettingsAppWidgetProvider") && actInfo.exported){
                return true;
            }
        }
    }

    return false; //default
}

Turn on location services without navigating to settings page

This dialog is created by LocationSettingsRequest.Builder available in the Google Play Services.

You need to add a dependency to your app build.gradle:

compile 'com.google.android.gms:play-services-location:10.0.1'

Then you can use this minimal example:

private void displayLocationSettingsRequest(Context context) {
    GoogleApiClient googleApiClient = new GoogleApiClient.Builder(context)
            .addApi(LocationServices.API).build();
    googleApiClient.connect();

    LocationRequest locationRequest = LocationRequest.create();
    locationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
    locationRequest.setInterval(10000);
    locationRequest.setFastestInterval(10000 / 2);

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

    PendingResult<LocationSettingsResult> result = LocationServices.SettingsApi.checkLocationSettings(googleApiClient, builder.build());
    result.setResultCallback(new ResultCallback<LocationSettingsResult>() {
        @Override
        public void onResult(LocationSettingsResult result) {
            final Status status = result.getStatus();
            switch (status.getStatusCode()) {
                case LocationSettingsStatusCodes.SUCCESS:
                    Log.i(TAG, "All location settings are satisfied.");
                    break;
                case LocationSettingsStatusCodes.RESOLUTION_REQUIRED:
                    Log.i(TAG, "Location settings are not satisfied. Show the user a dialog to upgrade location settings ");

                    try {
                        // Show the dialog by calling startResolutionForResult(), and check the result
                        // in onActivityResult().
                        status.startResolutionForResult(MainActivity.this, REQUEST_CHECK_SETTINGS);
                    } catch (IntentSender.SendIntentException e) {
                        Log.i(TAG, "PendingIntent unable to execute request.");
                    }
                    break;
                case LocationSettingsStatusCodes.SETTINGS_CHANGE_UNAVAILABLE:
                    Log.i(TAG, "Location settings are inadequate, and cannot be fixed here. Dialog not created.");
                    break;
            }
        }
    });
}

Turn on Location Providers Programmatically in Android

No, it is not,
but you can open the Location services settings window:

context.startActivity(new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS));

How to show enable location dialog like Google maps?

LocationSettingsRequest.Builder has a method setAlwaysShow(boolean show). While the document indicates it's currently doing nothing(updated 2015-07-05: updated Google documentation has removed this wording), setting builder.setAlwaysShow(true); will enable Google Maps behavior:

Here's the code that got it working:

if (googleApiClient == null) {
    googleApiClient = new GoogleApiClient.Builder(getActivity())
            .addApi(LocationServices.API)
            .addConnectionCallbacks(this)
            .addOnConnectionFailedListener(this).build();
    googleApiClient.connect();

    LocationRequest locationRequest = LocationRequest.create();
    locationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
    locationRequest.setInterval(30 * 1000);
    locationRequest.setFastestInterval(5 * 1000);
    LocationSettingsRequest.Builder builder = new LocationSettingsRequest.Builder()
            .addLocationRequest(locationRequest);

    //**************************
    builder.setAlwaysShow(true); //this is the key ingredient
    //**************************

    PendingResult<LocationSettingsResult> result =
            LocationServices.SettingsApi.checkLocationSettings(googleApiClient, builder.build());
    result.setResultCallback(new ResultCallback<LocationSettingsResult>() {
        @Override
        public void onResult(LocationSettingsResult result) {
            final Status status = result.getStatus();
            final LocationSettingsStates state = result.getLocationSettingsStates();
            switch (status.getStatusCode()) {
                case LocationSettingsStatusCodes.SUCCESS:
                    // All location settings are satisfied. The client can initialize location
                    // requests here.
                    break;
                case LocationSettingsStatusCodes.RESOLUTION_REQUIRED:
                    // Location settings are not satisfied. But could be fixed by showing the user
                    // a dialog.
                    try {
                        // Show the dialog by calling startResolutionForResult(),
                        // and check the result in onActivityResult().
                        status.startResolutionForResult(
                                getActivity(), 1000);
                    } catch (IntentSender.SendIntentException e) {
                        // Ignore the 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;
            }
        }
    });
}

Allow all the time location prompt not coming in Android SDK 29

In order to access the location in background on device running Android 10 (API level 29) or higher, you also need to use below permission in the manifest file

 <uses-permission android:name="android.permission.ACCESS_BACKGROUND_LOCATION" />

please refer the below link for more information
