onBackPressed（）但活动完成（），然后是onCreate（）和onResume（）。 无法退出应用

Question

Android 2.3.6
Steps to reproduce. Goto activity.
Restart Phone. Click Back Button. Nothing happens. Actually activity recreated again, then resume called() so cannot exit app. It just stays on. What could cause this. I have selected the app as default app launcher, so maybe this has something to do with it.

Question is how can this possibly not close the activity? I'm doing on back pressed, and I'm also doing a finish(). I have log statements in onResume(), so I don't think its being restarted. What is it about restarting the phone that does this. It works otherwise.

 @Override
 public void onBackPressed() {
        super.onBackPressed();
        finish();


    }
}

UPDATE: What happens is the activity is immediately recreated. onCreate(), onResume(). So the activity is stopped, but for some reason it does not leave. Here is activity intent filters in manifest:

       <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.DEFAULT" />
            <category android:name="android.intent.category.HOME" />
        </intent-filter>

Is there something about this that keeps me from exiting the app?
