public class GetRoundStroe {
    private Store[] stores;
    private Context mContext;

    public GetRoundStroe(Context mContext) {
        this.mContext = mContext;
    }

    public Store[] getStores() {
        if (ComCommand.haveInternet(mContext)) {
            start_am_normal();
        } else {
            start_am_silence();
        }
        return stores;
    }

    public Store[] start_am_silence() {


        long firstTime = SystemClock.elapsedRealtime();

        AlarmManager am = (AlarmManager) mContext.getSystemService(Context.ALARM_SERVICE);

        if (AlarmHolder.mAlarmNormal != null) {
            am.cancel(AlarmHolder.mAlarmNormal);

        }

        am.setRepeating(AlarmManager.ELAPSED_REALTIME_WAKEUP,
                firstTime, TestSwitch.getInstance().getSilence_time(), AlarmHolder.mAlarmSilence);


        return null;


    }

    public Store[] start_am_normal() {


        long firstTime = SystemClock.elapsedRealtime();

        AlarmManager am = (AlarmManager) mContext.getSystemService(Context.ALARM_SERVICE);

        if (AlarmHolder.mAlarmSilence != null) {
            MyLog.e(GetRoundStroe.class,"AlarmHolder.mAlarmSilence"+AlarmHolder.mAlarmSilence+"");
            am.cancel(AlarmHolder.mAlarmSilence);
        }
        am.setRepeating(AlarmManager.ELAPSED_REALTIME_WAKEUP,
                firstTime, TestSwitch.getInstance().getNormal_time(), AlarmHolder.mAlarmNormal);

        return null;
    }

    private static final class AlarmHolder {
        static final PendingIntent mAlarmSilence = PendingIntent.getService(ApplicationContext.getInstance(),
                0,
                new Intent(ApplicationContext.getInstance(), GetRoundSilenceService.class),
                0);

        static final PendingIntent mAlarmNormal = PendingIntent.getService(ApplicationContext.getInstance(),
                0, new
                Intent(ApplicationContext.getInstance(), GetRoundNormalService.class),
                0);

    }
}

GetRoundSilenceService and GerRoundNormalService invoke start_am_normal() or start_am_silence; Anyone could help me? thanks

Answer 1

   myIntent = new Intent(SetActivity.this, AlarmActivity.class);
   pendingIntent = PendingIntent.getActivity(CellManageAddShowActivity.this,
       id, myIntent, PendingIntent.FLAG_UPDATE_CURRENT);
   pendingIntent.cancel();
   alarmManager.cancel(pendingIntent);

These lines of code surely can help you remove/cancel the pending intent and alarm.

The main thing that you will need is:

1. Create pending intent with the same id and appropriate intent FLAG.
2. Cancel that pending intent.
3. Cancel the alarm using alarm manager.
