Answer 1

You can use Handler and its postDelayed() to fire Runnable to do the job. Once job its done runnable shall fire itself delayed again. Pseudo code:

Handler mHandler = new Handler();

in code, to start the avalanche:

mHandler.postDelayed( mRunnable, 60*1000 );

and runnable

Runnable mRunnable = new Runnable() {
   public void run() {
      // do your job

      mHandler.postDelayed( this, 60*1000 );
   }
}
