Java – date change listener

My task is to trigger a method to refresh or reset my application every 12 o'clock I tried to search the Internet for answers, but I couldn't find anything Can I use any method and / or listener in Android? Or any method?

Solution

Yes, you can listen to date / time changes on Android To do this, please explicitly register the broadcastreceiver of the following intention filter in the activity:

android.intent.action.ACTION_TIME_TICK

This intent is sent every minute You cannot receive this information through the component declared in the manifest, but only through context Registerreceiver() explicitly registers it

Your receiver (internal) course:

private final MyDateChangeReceiver mDateReceiver = new MyDateChangeReceiver();

public class MyDateChangeReceiver extends BroadcastReceiver{

    @Override
    public void onReceive(final Context context,Intent intent) {

        // compare current time and decide if it's 12 AM
        Log.d("MyDateChangeReceiver","Time changed");

    }
}

Register it in the onresume method:

registerReceiver(mDateReceiver,new IntentFilter(Intent.ACTION_TIME_TICK));

And don't forget to unregister in the onpause method:

unregisterReceiver(mDateReceiver);
