こんにちは、特定の時間にサウンドを再生する最初のAndroid アプリを作成しました。コードをうまく実行し、サウンドが再生される日時のリストを追加しました。モバイルがアラームとしてロックされたときにサウンドを再生する方法についてさらに検索したとき。最後に、アラームマネージャーを使用する必要があることに到達しました。できなかったので誰か助けてください。再生中のサウンドの下に追加した特定の時間を必要に応じて。

注：インターフェイスクラスを使用して、call htmlファイルをAndroid に呼び出します

public class WebAppInterface    {
Context mContext;
public  MediaPlayer mp = null;
 public static boolean checked = false;
/** Instantiate the interface and set the context */
WebAppInterface(Context c) {
    mContext = c;
    mp = MediaPlayer.create(mContext,R.raw.sound);

}


@JavascriptInterface
public void playsound(String value  ) throws ParseException {


   //get current date time with Date()

    String dateStr = "0, 3, 11, 9, 7, 2013"; 

    SimpleDateFormat dateFormat = new SimpleDateFormat("ss,hh,mm,yyyy,MM,dd"); 
    Time time = new Time();
    System.out.println(dateFormat.format(time));

    //1day
     time.set(0, 3, 11, 9, 7, 2013);
     time.set(0, 3, 18, 9, 7, 2013);
     time.set(0, 5, 0, 9, 7, 2013);
     time.set(0, 12, 1, 9, 7, 2013);
     time.set(0, 3, 37, 9, 7, 2013);
     time.set(0, 7, 0, 9, 7, 2013);
     time.set(0, 8, 32, 9, 7, 2013);
     //2day
     time.set(0, 3, 11, 10, 7, 2013);
     time.set(0, 3, 18, 10, 7, 2013);
     time.set(0, 5, 0, 10, 7, 2013);
     time.set(0, 12, 1, 10, 7, 2013);
     time.set(0, 3, 37, 10, 7, 2013);
     time.set(0, 7, 0, 10, 7, 2013);
     time.set(0, 8, 31, 10, 7, 2013);

first you need to create a class that extends BroadcastReceiver:

public class AlarmManagerBroadcastReciever extends BroadcastReceiver {

@Override
public void onReceive(Context context, Intent intent) {
    PowerManager pm = (PowerManager) context
            .getSystemService(Context.POWER_SERVICE);
    PowerManager.WakeLock wl = pm.newWakeLock(
            PowerManager.PARTIAL_WAKE_LOCK, "YOUR TAG");
    // Acquire the lock
    wl.acquire();
    MediaPlayer mp=MediaPlayer.create(context,R.raw.<your audio>);
    mp.start();
    // Release the lock
    /// do your playing sound here
    wl.release();
}

public void SetAlarm(Context con, int id, int hour, int min) {
    AlarmManager am = (AlarmManager) con
            .getSystemService(Context.ALARM_SERVICE);
    Calendar cal = Calendar.getInstance();
    cal.set(cal.get(Calendar.YEAR), cal.get(Calendar.MONTH),
            cal.get(Calendar.DAY_OF_MONTH), hour, min);
    Intent intent = new Intent(con, AlarmManagerBroadcastReciever.class);

    PendingIntent sender = PendingIntent.getBroadcast(con, id, intent,
            PendingIntent.FLAG_UPDATE_CURRENT);
    am.set(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), sender);
}

public void CancelAlarm(Context context, int size) {
            // canceling all alarms 
    for (int i = 0; i < size; i++) {
        Intent intent = new Intent(context,
                AlarmManagerBroadcastReciever.class);
        PendingIntent sender = PendingIntent.getBroadcast(context, i,
                intent, 0);
        AlarmManager alarmManager = (AlarmManager) context
                .getSystemService(Context.ALARM_SERVICE);
        alarmManager.cancel(sender);
    }
}

}

in your MainActivity make an object of this class:

AlarmManagerBroadcastReciever alarm = new AlarmManagerBroadcastReciever();

and add methods below:

public void startTimer(int hour, int min, int id) {
    Context context = this.getApplicationContext();
    if (alarm != null) {
        alarm.SetAlarm(context, id, hour, min);
    } else {
        Toast.makeText(context, "Alarm is null", Toast.LENGTH_SHORT).show();
    }
}

public void cancelTimer() {
    Context context = this.getApplicationContext();
    if (alarm != null) {
        alarm.CancelAlarm(context, <number of alarms>);
    } else {
        Toast.makeText(context, "Alarm is null", Toast.LENGTH_SHORT).show();
    }
}

use startTimer() to set specific alarm and in onRecieve() of broadcastReciever do your things.Don't forget to add your broadcastReciever to manifest file:

<receiver android:name="<package name>.AlarmManagerBroadcastReciever"
        >
    </receiver>

good luck ;)
