Question

This is my short description about my widget and main application. Sorry because of my English (English is not my mother tongue)

I have a music player widget. When this widget enabled, I need bind to a music player service (A) of main application. Because we cannot bind a service in AppWidgetProvider so I start a local service (B) in AppWidgetProvider and bind to that music player service (A) from here. Furthermore, I also have a service C to do widget’s button function.

Everything seems to be working fine but when my main app with service A all forced stop (they will be restating a moment later) I must rebind to A from widget. Problem is when main app was forced stop, I cannot rebind to A because context(I stored Context as a global variable in AppWidgetProvider whenever I receive context from onEnabled, onUpdate) is NULL.

My question is how about my above widget structure? Should service B stoped when bind to A done? How can i bind to service A again when main app and service a was forced stop (but they will automatically restart a moment later).

Thanks you!

Answer my own question

1. First, We can bind Service from widget, using context.getApplicationContext().bindService(..)
2. When main application was forced stop, to bind service again on onUpdate() use application context MyMainApplication.Instance().getApplicationContext().bindService(..)
