I m making adapter to adapt my book collection to be visible in list view. Issue is solved if I add super(context, position): public BookAdapter(Context context, int position, List <Book> updatedBooksList) { super(context, position); this.context = context; this.booksList = updatedBooksList ; } However, I want to know why I need this argument (int position) and call superclass constructor? protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); Also, in the broader sense why do we always(?) need to call super.onCreate like here in every onCreate? Aren't we

I have a broadcast receiver registered programatically in a activity. It responds to the PACKAGE_REMOVED intent, that fires when a package gets removed. The problem is, it doesn't get this message. I think this is due to that the intent is fired when I leave the activity and move to another activity to uninstall a app, so the original activity is paused. Could it be that a paused activity (where the receiver is not unregistered in onPause ) also pauses the receiver? When you register a broadcast receiver programatically in an activity, it will NOT get broadcasts when the activity is paused.

I have developed a Count Down Timer and I am not sure how to pause and resume the timer as the textview for the timer is being clicked. Click to start then click again to pause and to resume, click again the timer's text view. This is my code: Timer = (TextView) this.findViewById(R.id.time); //TIMER Timer.setOnClickListener(TimerClickListener); counter = new MyCount(600000, 1000); }//end of create private OnClickListener TimerClickListener = new OnClickListener() { public void onClick(View v) { updateTimeTask(); } private void updateTimeTask() { if (decision == 0) { counter.start(); decision =

When using ViewPager with fragments, our onPause(), onResume() methods are not called when moving between tabs. Is there any way we can figure out in the fragment when we're being made visible or being hidden? Unfortunately I have logic in onResume(), onPause(), like registering with location services, that never get stopped when switching tabs because onPause() never gets called until one exits the whole app. Thanks The ViewPager comes with the OnPageChangeListener interface. By setting some flags for the previous and currently shown pages, you can emulate this behavior. Considering previous

My application gets killed each time that it comes back from the screen-off-state. I fetch all the information that my app does, but I can't find out why it calls onDestroy. It's the first time I'm seeing this behavior in my applications. My main activity extends tabActivity because it contains a tabhost. I've read that it has to extend it or it will FC. I'm not sure if my issue is related to this?! Oh and it implements Observer but this should be no problem.
