Android - What is the best way to do something every time the time changes?

Question

I want a do something every time a minute passes, for example when the time changes from 10:38 to 10:39 i want to do something.

What is the best way to do this?

If you want to do something even if the app is stopped you should use services. Otherwise you can create a timer and map it to the clock time — Ispas Claudiu, Mar 16 '17 at 09:42

You need to listen for TIME_TICK via broadcast receiver

IntentFilter timeTickIntentFilter = new IntentFilter(Intent.ACTION_TIME_TICK);
registerReceiver(YourReceiver, timeTickIntentFilter);

Use AlarmManager for this.

void startSchedulerAlarm() {
    int oneMinute = 1 * (60 * 1000); //Trigger Every 1 Minute
    AlarmManager alarmManager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
    Intent intent = new Intent(context, AlarmReceiver.class);
    intent.setAction(AlarmReceiver.alaramIntent);
    PendingIntent alarmIntent = PendingIntent.getBroadcast(context, AlarmReceiver.alarmIntentCode, intent, PendingIntent.FLAG_UPDATE_CURRENT);
    alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, System.currentTimeMillis(), oneMinute, alarmIntent);

}

void stopSchedulerAlarm() {
    AlarmManager alarmManager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
    Intent intent = new Intent(context, AlarmReceiver.class);
    intent.setAction(AlarmReceiver.alaramIntent);
    PendingIntent alarmIntent = PendingIntent.getBroadcast(context, AlarmReceiver.alarmIntentCode, intent, PendingIntent.FLAG_UPDATE_CURRENT);
    alarmManager.cancel(alarmIntent);
}

Create a receiver for your Alarm in Manifest:

    <receiver       
        android:name="{YOUR_PACKAGE_NAME}.AlarmReceiver"
        android:enabled="true"
        android:process=":remote">
        <intent-filter>
            <action android:name="{YOUR_PACKAGE_NAME}.alarmIntent"/>
        </intent-filter>
    </receiver>

public class AlarmReceiver extends BroadcastReceiver {

public static final String alaramIntent = "{YOUR_PACKAGE_NAME}.alarmIntent";
public static final int alarmIntentCode = 000054310;

private String TAG = AlarmReceiver.class.getSimpleName();

   @Override
   public void onReceive(Context context, Intent intent) {
        //Do something Here
   }
}

Keep a Service running in the background that keeps on checking for a specidied time, Say you want to do turn the phone to silent mode when it's 10:00 PM. So the service should keep on checking if the time is 10:00 PM and when it is, execute the code to turn the phone to silent mode
