SMSが将来送信されるAndroidアプリケーションを開発しようとしています。将来の日付は、ユーザーからの入力として取得されます。ここでの問題は、カウント ダウン タイマーを数日や数時間などの長期間にわたって使用する方法です。

参考のために、この回答を投稿しています。時間遅延を使用して通知を送信したため、変更して使用できるため、これから助けを得ることができます 

public class AutoNotification extends Activity {
    private Timer refresh = null;
    private final long refreshDelay = 5 * 1000;//this delay will be your time that the user will provide you
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        //setContentView(R.layout.activity_auto_notification);

        sensSMSThread = new sensSMSRequest();
        sensSMSThread.start();

    }
    class sensSMSRequest extends Thread {
        boolean sendHttpRequest;
        public sensSMSRequest() {

            sendHttpRequest = true;
        }

        public void stopSendingHttpRequest() {
            sendHttpRequest = false;
        }

        protected void onStop() {
            sensSMSThread.stopSendingHttpRequest();
            super.stop();
        }

        @Override
        public void run() {
            while (sendHttpRequest) {
                sendSms();


                SystemClock.sleep(refreshDelay);
            }
        }
    }
}

どういうわけかそれがあなたを助けることを願っています

インテント フィルタを作成します。

 static {
    s_intentFilter = new IntentFilter();
    s_intentFilter.addAction(Intent.ACTION_TIME_TICK);
    s_intentFilter.addAction(Intent.ACTION_TIMEZONE_CHANGED);
    s_intentFilter.addAction(Intent.ACTION_TIME_CHANGED);
}

および放送受信機:

private final BroadcastReceiver m_timeChangedReceiver = new BroadcastReceiver() {
    @Override
    public void onReceive(Context context, Intent intent) {
        final String action = intent.getAction();

        if (action.equals(Intent.ACTION_TIME_CHANGED) ||
            action.equals(Intent.ACTION_TIMEZONE_CHANGED))
        {
           //if(current time == sechduled time)  doyourWork();
        }
    }
};

受信者をサービスに登録します。

 public void onCreate() {
    super.onCreate();
    registerReceiver(m_timeChangedReceiver, s_intentFilter);     
}

注 :デバイスの再起動後にサービスを再度開始することを忘れないでください。
