I have an app, a single activity app with fragments in it. The usual use case for this app is, that you start it and put the phone away and every now and then, you get back to the phone and insert some data...

(Most of the time this is not the case, but every now and then this happens...). My app sometimes starts a service, even this service is killed in this case... This means, that the system has

I am creating a tabs list with several fragments.

And if I want to update data, how do I put it in onResume()? Mr.Sandy Any Activity that restarts has its onResume() method executed first. To use this method, do this: @Override public void onResume(){ super.onResume(); // put your code here... } Viswanath Lekshmanan Restarting the app will call OnCreate() . Continuing the app when it is paused will call OnResume() . From the official docs at https:/

From android doc here http://developer.android.com/reference/android/app/Activity.html , it said 'Activity comes into foreground' will call onPause() , and 'Activity is no longer visible' will call onStop() . Isn't 'Activity comes into foreground' same as 'Activity is no longer visible'? Can you please tell me what is the difference between them? No, if some activity comes into foreground, that doesn't necessarily mean that the other activity is completely invisible. Consider the following case: Here we see both activities at the same time. The first activity with the fields is obscured by
