I know that the question about turning on/off GPS programatically on android has been discussed many times, and the answer is always the same:
"You can't for security/privacy reasons, you have to forward to location preferences screen and let the user enable/disable it."
I understand that, however I recently bought Tasker from the market and, among many other things that you can accomplish with it, you can set rules to auto-enable GPS on entering pre-determined applications and disable it on exit (see here for the tutorial on how to do it, and it just works!) and this app can't be signed with the firmware signing key as it works on many android versions and different devices and you don't even need to be rooted.
I would like to do this in my app. Of course, I don't want to blow up the users privacy, so I would first ask the user if he wants to turn it on automatically with the typical "remember my decision" checkbox and if he answers yes, enable it.
Does anybody have any idea or clue on how Tasker achieves this?
The answer is
An answer was developed in another question, but it was closed, and I'd like the community to try it out as well.
boolean gpsStatus = locmanager.isProviderEnabled(LocationManager.GPS_PROVIDER);
if (!gpsStatus) {
Settings.Secure.putString(getContentResolver(), Settings.Secure.LOCATION_PROVIDERS_ALLOWED, "network,gps");
}
See this comment
This solution would require the WRITE_SETTINGS and WRITE_SECURE_SETTINGS permissions.
Maybe with reflection tricks around the class android.server.LocationManagerService.
Also, there is a method (since API 8) android.provider.Settings.Secure.setLocationProviderEnabled
To turn GPS on or off programatically you need 'root' access and BusyBox installed. Even with those, the task is not trivial.
Sample's here: Google Drive, Github, Sourceforge
Tested with 2.3.5 and 4.1.2 Androids.
Things have changed since this question was posted, now with new Google Services API, you can prompt users to enable GPS:
https://developers.google.com/places/android-api/current-place
You will need to request ACCESS_FINE_LOCATION permission in your manifest:
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
Also watch this video:
This is a more statble code for all Android versions and possibly for new ones
void checkGPS() {
LocationRequest locationRequest = LocationRequest.create();
LocationSettingsRequest.Builder builder = new LocationSettingsRequest.Builder().addLocationRequest(locationRequest);
SettingsClient settingsClient = LocationServices.getSettingsClient(this);
Task<LocationSettingsResponse> task = settingsClient.checkLocationSettings(builder.build());
task.addOnSuccessListener(this, new OnSuccessListener<LocationSettingsResponse>() {
@Override
public void onSuccess(LocationSettingsResponse locationSettingsResponse) {
Log.d("GPS_main", "OnSuccess");
// GPS is ON
}
});
task.addOnFailureListener(this, new OnFailureListener() {
@Override
public void onFailure(@NonNull final Exception e) {
Log.d("GPS_main", "GPS off");
// GPS off
if (e instanceof ResolvableApiException) {
ResolvableApiException resolvable = (ResolvableApiException) e;
try {
resolvable.startResolutionForResult(ActivityMain.this, REQUESTCODE_TURNON_GPS);
} catch (IntentSender.SendIntentException e1) {
e1.printStackTrace();
}
}
}
});
}
And you can handle the GPS state changes here
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if(requestCode == Static_AppVariables.REQUESTCODE_TURNON_GPS) {
switch (resultCode) {
case Activity.RESULT_OK:
// GPS was turned on;
break;
case Activity.RESULT_CANCELED:
// User rejected turning on the GPS
break;
default:
break;
}
}
}
Use This code Simple and Easy to Access:
Permissions:
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
Follow this Code to access the GPS programmatically:
LocationManager locationManager ;
boolean GpsStatus ;
GPSStatus();
if(GpsStatus == true)
{
textview.setText("Your Location Services Is Enabled");
}else
{textview.setText("Your Location Services Is Disabled");}
Intent intent = new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS);
startActivity(intent);
public void GPSStatus(){
locationManager = (LocationManager)context.getSystemService(Context.LOCATION_SERVICE);
GpsStatus = locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER);
}
This code works on ROOTED phones if the app is moved to /system/aps, and they have the following permissions in the manifest:
<uses-permission android:name="android.permission.WRITE_SETTINGS"/>
<uses-permission android:name="android.permission.WRITE_SECURE_SETTINGS"/>
Code
private void turnGpsOn (Context context) {
beforeEnable = Settings.Secure.getString (context.getContentResolver(),
Settings.Secure.LOCATION_PROVIDERS_ALLOWED);
String newSet = String.format ("%s,%s",
beforeEnable,
LocationManager.GPS_PROVIDER);
try {
Settings.Secure.putString (context.getContentResolver(),
Settings.Secure.LOCATION_PROVIDERS_ALLOWED,
newSet);
} catch(Exception e) {}
}
private void turnGpsOff (Context context) {
if (null == beforeEnable) {
String str = Settings.Secure.getString (context.getContentResolver(),
Settings.Secure.LOCATION_PROVIDERS_ALLOWED);
if (null == str) {
str = "";
} else {
String[] list = str.split (",");
str = "";
int j = 0;
for (int i = 0; i < list.length; i++) {
if (!list[i].equals (LocationManager.GPS_PROVIDER)) {
if (j > 0) {
str += ",";
}
str += list[i];
j++;
}
}
beforeEnable = str;
}
}
try {
Settings.Secure.putString (context.getContentResolver(),
Settings.Secure.LOCATION_PROVIDERS_ALLOWED,
beforeEnable);
} catch(Exception e) {}
}
This one works for me.
It is simpler then Rj0078's answer in this question (https://stackoverflow.com/a/42556648/11211963), but that one is worked as well.
It shows a dialog like this:
(Written in Kotlin)
googleApiClient = GoogleApiClient.Builder(context!!)
.addApi(LocationServices.API).build()
googleApiClient!!.connect()
locationRequest = LocationRequest.create()
locationRequest!!.priority = LocationRequest.PRIORITY_HIGH_ACCURACY
locationRequest!!.interval = 30 * 1000.toLong()
locationRequest!!.fastestInterval = 5 * 1000.toLong()
val builder = LocationSettingsRequest.Builder()
.addLocationRequest(locationRequest!!)
builder.setAlwaysShow(true)
result =
LocationServices.SettingsApi.checkLocationSettings(googleApiClient, builder.build())
result!!.setResultCallback { result ->
val status: Status = result.status
when (status.statusCode) {
LocationSettingsStatusCodes.SUCCESS -> {
// Do something
}
LocationSettingsStatusCodes.RESOLUTION_REQUIRED ->
try {
startResolutionForResult(),
status.startResolutionForResult(
activity,
REQUEST_LOCATION
)
} catch (e: SendIntentException) {
}
LocationSettingsStatusCodes.SETTINGS_CHANGE_UNAVAILABLE -> {
// Do something
}
}
}
Above correct answer is very old it needs something new so Here is answer
As in last update we have androidx support so first include dependency in your app level build.gradle file
implementation 'com.google.android.gms:play-services-location:17.0.0'
then add in your manifest file:
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
don't forget to take user consent for these permissions if you are releasing
now here is code just use it
protected void createLocationRequest() {
LocationRequest locationRequest = LocationRequest.create();
locationRequest.setInterval(10000);
locationRequest.setFastestInterval(5000);
locationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
LocationSettingsRequest.Builder builder = new LocationSettingsRequest.Builder()
.addLocationRequest(locationRequest);
SettingsClient client = LocationServices.getSettingsClient(this);
Task<LocationSettingsResponse> task = client.checkLocationSettings(builder.build());
task.addOnSuccessListener(this, new OnSuccessListener<LocationSettingsResponse>() {
@Override
public void onSuccess(LocationSettingsResponse locationSettingsResponse) {
// All location settings are satisfied. The client can initialize
// location requests here.
// ...
Toast.makeText(MainActivity.this, "Gps already open",
Toast.LENGTH_LONG).show();
Log.d("location settings",locationSettingsResponse.toString());
}
});
task.addOnFailureListener(this, new OnFailureListener() {
@Override
public void onFailure(@NonNull Exception e) {
if (e 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) e;
resolvable.startResolutionForResult(MainActivity.this,
REQUEST_CHECK_SETTINGS);
} catch (IntentSender.SendIntentException sendEx) {
// Ignore the error.
}
}
}
});
}
@Override
protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if(requestCode==REQUEST_CHECK_SETTINGS){
if(resultCode==RESULT_OK){
Toast.makeText(this, "Gps opened", Toast.LENGTH_SHORT).show();
//if user allows to open gps
Log.d("result ok",data.toString());
}else if(resultCode==RESULT_CANCELED){
Toast.makeText(this, "refused to open gps",
Toast.LENGTH_SHORT).show();
// in case user back press or refuses to open gps
Log.d("result cancelled",data.toString());
}
}
}

This is the best solution provided by Google Developers. Simply call this method in onResume of onCreate after initializing GoogleApiClient.

// Get the businesses and other points of interest located
// nearest to the device's current location.

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);
LocationSettingsRequest.Builder builder = new LocationSettingsRequest
.Builder()
.addLocationRequest(mLocationRequest);
PendingResult<LocationSettingsResult> resultPendingResult = LocationServices
.SettingsApi
.checkLocationSettings(mGoogleApiClient, builder.build());
resultPendingResult.setResultCallback(new ResultCallback<LocationSettingsResult>() {
@Override
public void onResult(@NonNull LocationSettingsResult locationSettingsResult) {
final Status status = locationSettingsResult.getStatus();
final LocationSettingsStates locationSettingsStates = locationSettingsResult.getLocationSettingsStates();
switch (status.getStatusCode()) {
case LocationSettingsStatusCodes.SUCCESS:
// All location settings are satisfied. The client can
// initialize location requests here.
break;
case LocationSettingsStatusCodes.RESOLUTION_REQUIRED:

} catch (IntentSender.SendIntentException e) {
// Ignore the error.
}
break;
case LocationSettingsStatusCodes.SETTINGS_CHANGE_UNAVAILABLE:
// Location settings are not satisfied. However, we have no way

break;
}
}
});

Here is how OLA Cabs and other such apps are doing it.
Add this in your onCreate
if (googleApiClient == null) {
googleApiClient = new GoogleApiClient.Builder(this)
.addApi(LocationServices.API).addConnectionCallbacks(this)
.addOnConnectionFailedListener(Login.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()) {

public void onConnected(Bundle arg0) {
// TODO Auto-generated method stub
}
@Override
public void onConnectionSuspended(int arg0) {
// TODO Auto-generated method stub
}
@Override
public void onConnectionFailed(ConnectionResult arg0) {
// TODO Auto-generated method stub

Edit: Adding Irfan Raza's comment for more help.
@Override protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == 1000) {
if(resultCode == Activity.RESULT_OK){
String result=data.getStringExtra("result");
} if (resultCode == Activity.RESULT_CANCELED) {
//Write your code if there's no result
}
}
}
Instead of using intent Settings.ACTION_LOCATION_SOURCE_SETTINGS you can directly able to show pop up in your app like Google Map & on Gps on click of ok button their is no need to redirect to setting simply you need to use my code as

This code works on ROOTED phones:
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
String[] cmds = {"cd /system/bin" ,"settings put secure location_providers_allowed +gps"};
try {
Process p = Runtime.getRuntime().exec("su");
DataOutputStream os = new DataOutputStream(p.getOutputStream());
for (String tmpCmd : cmds) {
os.writeBytes(tmpCmd + "\n");
}
os.writeBytes("exit\n");
os.flush();
}
catch (IOException e){
e.printStackTrace();
}
}
}
For turning off GPS you can use this command instead
settings put secure location_providers_allowed -gps
You can also toggle network accuracy using the following commands: for turning on use:
settings put secure location_providers_allowed +network
and for turning off you can use:
settings put secure location_providers_allowed -network
Since Android version 4.4, you can't enable/disable gps programatically. If you try the code proposed on this answer, an exception will be fired.
java.lang.SecurityException: Permission Denial: not allowed to send broadcast android.location.GPS_ENABLED_CHANGE
You just need to remove the LocationListener from LocationManager
manager.removeUpdates(listener);
ENABLE GPS:
Intent intent=new Intent("android.location.GPS_ENABLED_CHANGE");
intent.putExtra("enabled", true);
sendBroadcast(intent);
DISABLE GPS:
Intent intent = new Intent("android.location.GPS_ENABLED_CHANGE");
intent.putExtra("enabled", false);
sendBroadcast(intent);
