I am developing an application and using Mobile Vision Api for text recognizing.I noticed that its not working in some devices.After searched I understand that one reason is because of google play service version that is installed on user device.So I know that I can get the version that is installed on user device like this :
int v = getPackageManager().getPackageInfo("com.google.android.gms", 0 ).versionCode;
but what is the minimum version that i have to check on user device to notice to the user to update the google play service on device(if necessary)?
