Я не могу отменить будильник Android, когда он запустился ⇐ Android

[Anonymous]

Я неоднократно пытался добавить функции, которые могли бы позволить пользователям отключать будильник Android, который объявляет текущее время с помощью механизма преобразования текста в речь Android в течение десяти минут, но отменить это не удалось.
Будильник вибрирует один раз, а затем непрерывно сообщает текущее время в течение десяти минут. Теперь я хочу добавить кнопку остановки, которую можно использовать для отмены будильника при нажатии, но все мои попытки не увенчались успехом. Ниже мой код
public class AlarmReceiver extends BroadcastReceiver {
private TextToSpeech textToSpeech;
private Handler handler;
private PendingIntent pendingIntent;
private Context appContext;
private final int totalDuration = 10 * 60 * 1000; // 10 minutes
private long startTime;
private boolean isAlarmStopped = false; // Alarm stopped flag

@Override
public void onReceive(Context context, Intent intent) {
Log.d("AlarmReceiver", "onReceive() called");

appContext = context;

// Check if the alarm should be stopped
if (intent.getBooleanExtra("STOP_ALARM", false)) {
stopAnnouncements();
return; // Immediately exit to prevent further execution
}

if (isAlarmStopped) {
Log.d("AlarmReceiver", "Alarm already stopped.");
return;
}

Log.d("AlarmReceiver", "Starting alarm sequence.");

// Vibrate the device
Vibrator vibrator = (Vibrator) context.getSystemService(Context.VIBRATOR_SERVICE);
if (vibrator != null) {
vibrator.vibrate(2000); // Vibrate for 2 seconds
}

// Initialize Text-to-Speech only once
if (textToSpeech == null) {
textToSpeech = new TextToSpeech(context, status -> {
if (status == TextToSpeech.SUCCESS) {
textToSpeech.setLanguage(Locale.getDefault());
startTime = System.currentTimeMillis();
startAnnouncingTime();
}
});
} else {
startAnnouncingTime();
}
}

private void startAnnouncingTime() {
handler = new Handler(Looper.getMainLooper());
Runnable timeAnnouncer = new Runnable() {
@Override
public void run() {
// Check if the alarm was stopped
if (isAlarmStopped) {
Log.d("AlarmReceiver", "Stopping announcements due to stop flag.");
return; // Exit without rescheduling
}

// Announce current time
Calendar calendar = Calendar.getInstance();
String timeText = String.format(Locale.getDefault(), "The current time is %d:%02d",
calendar.get(Calendar.HOUR_OF_DAY), calendar.get(Calendar.MINUTE));

if (textToSpeech != null && !isAlarmStopped) {
String utteranceId = "TTS_Alarm"; // Use a unique identifier for announcements
textToSpeech.speak(timeText, TextToSpeech.QUEUE_FLUSH, null, utteranceId);
}

// Reschedule if not stopped
if (!isAlarmStopped) {
handler.postDelayed(this, 5000); // Reschedule after 5 seconds
}
}
};

handler.post(timeAnnouncer);

Log.d("AlarmReceiver", "Running timeAnnouncer, isAlarmStopped: " + isAlarmStopped);
}

private void stopAnnouncements() {
Log.d("AlarmReceiver", "Stopping alarm and announcements.");

// Set the stop flag
isAlarmStopped = true;

// Stop handler tasks immediately
if (handler != null) {
handler.removeCallbacksAndMessages(null);
Log.d("AlarmReceiver", "Handler callbacks removed.");
}

// Stop TextToSpeech if initialized
if (textToSpeech != null) {
Log.d("AlarmReceiver", "Stopping TextToSpeech.");
textToSpeech.stop(); // Stops all ongoing speech
textToSpeech.shutdown(); // Full shutdown
Log.d("AlarmReceiver", "TextToSpeech successfully stopped and shutdown.");
}

textToSpeech = null; // Ensure nullification occurs here

// Stop vibration
if (appContext != null) {
Vibrator vibrator = (Vibrator) appContext.getSystemService(Context.VIBRATOR_SERVICE);
if (vibrator != null) {
vibrator.cancel();
Log.d("AlarmReceiver", "Vibration canceled.");
}
}

Log.d("AlarmReceiver", "Alarm completely stopped.");
}
}
