Detect or prevent if user uses fake location

Question

I will block a user from using my app if they fake the location. So I use isFromMockProvider to check if the location is fake (follow here). But isFromMo

Answer 1

I use this method in my projects and it work perfectly till now:

for api < 18

//returns true if mock location enabled, false if not enabled.
public static boolean isMockLocationOn(Context context) {
    if (Settings.Secure.getString(context.getContentResolver(), Settings.Secure.ALLOW_MOCK_LOCATION).equals("0"))
        return false;
    else
        return true;
}

For api >= 18 you should use

location.isFromMockProvider();

The point is location.isFromMockProvider is buggy and some times it will show a mocked location as its OK !!! There is a workaround in this link with full detail Location on Android: Stop Mocking Me!

the approach is :

• Remember the most recent location labeled as a mock

• If a new “non-mock” reading is within 1km of the last mock, reject it.

• Only clear the last mock location after 20 consecutive “non-mock” readings.
