How to turn on GPS sensor and get location from a service in Android M?

Question

I am new to a service. I want to turn on my GPS sensor and get the lat and long coordinate of GPS. I am using Android M, I provided the permission for my app. However, I cannot enable and get coordinate. Could you help me?

code :

//Enable gps
String provider = Settings.Secure.getString(getContentResolver(), Settings.Secure.LOCATION_PROVIDERS_ALLOWED);
if(!provider.contains("gps")) {
    new Handler(getMainLooper()).post(new Runnable() {
        @Override
        public void run() {
            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);
        }
    });
}

Why are you using a handler, a looper and a runnable to start an intent? — greenapps, Mar 04 '17 at 11:48
Because I am in BroadcastReceiver of a service. Without using Handler, I got error — John, Mar 04 '17 at 11:50
You should answer all questions. Especially you should tell what your code does. — greenapps, Mar 04 '17 at 11:51
Sorry. I have deleted the runnable and it still worked. The code does not have error but the GPS sensor cannot enable. — John, Mar 04 '17 at 11:52

@CommonsWare: Thanks. It means we cannot turn on the GPS sensor from code if it is turn off. Is it right? Note that, I am using normal phone without root — John, Mar 04 '17 at 12:02

You can not switch on or switch off GPS programatically in android. Could you clearify your question more, whether you are getting trouble in switching GPS on and off or in getting lat long` if the problem is switching it on and off then you can guide the user to setting screen and ask them to switch on user when ever you need , here is code

`final LocationManager manager = (LocationManager) getSystemService(Context.LOCATION_SERVICE );
if ( !manager.isProviderEnabled( LocationManager.GPS_PROVIDER ) ) {
 new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS);
 startActivity(intent);
}`

Yes. First. My GPS is turn off now. I want to use programmatically to turn on it. Then. I want to get the coordinate value from the sensor. Thanks – John Mar 04 '17 at 11:59
The one which you used is an exploit , it might not work for your device – Navneet Kumar Mar 04 '17 at 12:20
Thanks. SO could you give me the way to get coordinate with simple way? Assume that GPS is on now – John Mar 04 '17 at 15:04

first you need run time permission for location in marshmallow android version

add your main activity

in oncreate() method

 if (ActivityCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
        Log.d("PLAYGROUND", "Permission is not granted, requesting");
        ActivityCompat.requestPermissions(this, new String[]{android.Manifest.permission.ACCESS_FINE_LOCATION}, 123);

    } else {
        Log.d("PLAYGROUND", "Permission is granted");
    }

below oncreate() method

@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
    if (requestCode == 123) {
        if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
            Log.d("PLAYGROUND", "Permission has been granted");

        } else {
            Log.d("PLAYGROUND", "Permission has been denied or request cancelled");
            finish();
        }
    }
}

and then as usual your stuff

It is not permission issue. It is turn on GS issue – John Mar 05 '17 at 01:51 — John, Mar 05 '17 at 01:51
