Hi, Kai- We cannot tell from what you posted what is going on. Please take a look at how and when you create the Application, the BroadcastReceiver and the Service. Are they all in the same process? Recall that, for example, if you create the BroadcastReceiver using the <receiver> tag in the Manifest, if you specify no flags, it defaults to running in the same process as the Application (http://developer.android.com/reference/android/R.styleable.html#AndroidManifestReceiver_process).
But if, for example, the process 'hosting' the BroadcastReceiver has no other component, then when the BroadcastReceiver is done, the OS will aggressively kill the hosting process. The simplest approach is to use the same process for all three: Application, Service & BroadcastReceiver. Then the process will stick around until all three are backgrounded or killed (except under "conditions of extreme memory pressure"). See http://developer.android.com/guide/topics/processes/process-lifecycle.html for details on what is liable to be killed under what circumstances.
