scheduled alarm to repeat every minute of the clock android

Question

I have an app which requires a code to be executed every minute. But the issue is that the code has to be executed at every minute change of the clock. Which means,

If its 12:34 then the code will execute at 12:35 and goes on. But my current code works but it includes the seconds. Meaning,

If its 12:34:30 and the alarm starts, the code is executed. But the code is then executed at 12:35:30.

I want the code to be executed each minute according to the clock of the phone. Below is the current code.

 Intent intent2 = new Intent(MainActivity.this, MyABService.class);
                PendingIntent pintent = PendingIntent.getService(MainActivity.this, 0, intent2, 0);
                AlarmManager alarm_manager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
                alarm_manager.setRepeating(AlarmManager.RTC, c.getTimeInMillis(), 1 * 1000, pintent);

Im making it execute every second so that the effect takes place at the exact time. Instead of having it every second i need it to repeat itself at every minute change of the clock (every minute)

How do i go about this

Answer 1

Use Intent.ACTION_TIME_TICK This is a broadcast intent fired every minute by the Android OS. Register to it as you would register to a normal system broadcast in code (doesn't work from manifest)

tickReceiver=new BroadcastReceiver(){
    @Override
    public void onReceive(Context context, Intent intent) {
    if(intent.getAction().compareTo(Intent.ACTION_TIME_TICK)==0)
    {
      //do something
    }
  };

  //Register the broadcast receiver to receive TIME_TICK
  registerReceiver(tickReceiver, new IntentFilter(Intent.ACTION_TIME_TICK));
