I am wrapping a Lib which used a Service. It crashes when i try to connect in the Lib.
In the connect the lib starts the Service.
Inside the Service there is a Method which uses getBaseContext() but it crashes at this line in the Service:
private void LoadPreferences(Boolean NotifyOfChanges) {
SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(getBaseContext());
The
seems to be from the Android Activity or so. don´t know exactly.
maybe android.content.ContextWrapper

The Source of the Service is attached.
Any hints how i can change the Service to get the right reference to the b4a Activity?
