Simulate Android killing and restarting a service

Question

I want to simulate killing Android and restart my service to check what happens when I get zero meaning and what I need to do with cleanup / restore. Is it possible?

public MyService extends Service { @Override public void onCreate() { //Do stuff } @Override public void onStartCommand(Intent intent, int flags, int startId) { if (intent == null) { //Do stuff for restart } else { //Do stuff for normal start return START_STICKY; } } @Override public void onDestroy() { //Cleanup that may never be called! } } 

Note. I am reading how-to-simulate-android-killing-my-process . The answers are very helpful! But I think my use case is a little different.

You can use the same method to simulate kill and restart the service.

Launched the service ( onStartCommand returns START_STICKY ), logcat shows:

 08-13 11:55:38.649 24159-24159/? D/TAG: onCreate() 08-13 11:55:38.650 24159-24159/? D/TAG: onStartCommand: intent is null? false; flags=0; startId=1 

At this point, the following command to kill the process:

 adb shell ps | grep <package name> | awk '{print $2}' | xargs adb shell run-as <package name again> kill 

The service was restarted immediately (note the new process identifier and the fact that the target is zero):

 08-13 11:55:43.742 24236-24236/? D/TAG: onCreate() 08-13 11:55:43.743 24236-24236/? D/TAG: onStartCommand: intent is null? true; flags=0; startId=2
