Title Body

I'm currently working on an Android app. I would like to use the app icon in the action bar to navigate to the "home" activity. I read on this page that all that needs to be done is to add an onOptionsItemSelected and look for the id android.R.id.home . This is the code that I have implemented in my activity where I want to press the app icon to return to HomeActivity . @Override public boolean onOptionsItemSelected(MenuItem item) { switch(item.getItemId()) { case android.R.id.home: Intent intent = new Intent(this, HomeActivity.class); intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP); startActivity(intent); return true; default: return super.onOptionsItemSelected(item); } } However, nothing happens. When debugging, I can see that clicking the icon doesn't trigger the onOptionsItemSelected() at all. Do I have to do something with the icon somewhere? As of now, it's all default, just this in the AndroidManifest.xml <application android:icon="@drawable/ic_launcher" android:label="@string/app_name" >
