Dianne, here's the reproduction step on Froyo:
[1] Run on Froyo - start ApiDemos, start the RemoveService sample. You
will now see two processes
com.example.android.apis
com.example.android.apis:remote
[2] You will notice that "Sample Remote Service" appears on status
bar.
[3] write an app with KILL_BACKGROUND_PROCESSES permission. Call
ActivityManager.killBackgroundProcesses("com.example.android.apis");
[4] Both processes created at step [1] are killed.
[5] RemoveService is never restarted, even though you see something
like
W/ActivityManager( 2426): Scheduling restart of crashed service
com.example.android.apis/.app.RemoteService in 20000ms
[6] "Sample Remote Service" message still stays on status bar. This is
because StatusBarService expects a ACTION_PACKAGE_RESTARTED broadcast,
but
this braodcast is never delivered.
What's the best way to handle this -- we need to clean up some
resources if
the app process is killed.
Thanks!
