Change Location Mode to High Accuracy Programmatically Android

It is possible to get the device’s current location mode since API level 19 (Kitkat):

public int getLocationMode(Context context) {
    return Settings.Secure.getInt(activityUnderTest.getContentResolver(), Settings.Secure.LOCATION_MODE);
}

These are the possible return values (see here):

0 = LOCATION_MODE_OFF  
1 = LOCATION_MODE_SENSORS_ONLY  
2 = LOCATION_MODE_BATTERY_SAVING  
3 = LOCATION_MODE_HIGH_ACCURACY

So you want something like

if(getLocationMode(context) == 3) {
    // do stuff
}

Unfortunately you can’t set the location mode programmatically but you can send the user directly to the settings screen where he can do that:

startActivity(new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS));
