gps – 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));

You can provide criteria in the LocationMamager.requestLocationUpdates. As criteria you can provide one of the following values to select the accuracy needed.

Constants
int ACCURACY_COARSE A constant indicating an approximate accuracy requirement
int ACCURACY_FINE   A constant indicating a finer location accuracy requirement
int ACCURACY_HIGH   a constant indicating a high accuracy requirement - may be used for horizontal, altitude, speed or bearing accuracy.
int ACCURACY_LOW    A constant indicating a low location accuracy requirement - may be used for horizontal, altitude, speed or bearing accuracy.
int ACCURACY_MEDIUM A constant indicating a medium accuracy requirement - currently used only for horizontal accuracy.

See
http://developer.android.com/reference/android/location/LocationManager.html#requestLocationUpdates(long, float, android.location.Criteria, android.app.PendingIntent)

Since API level 28, you should use LocationManager.isProviderEnabled() to find out if a specific provider is enabled or not.

Changing the setting programmatically from your app is unfortunately not possible.
