I have a problem with my app. I have 2 button Start and Stop, when I click start notification is created and updated in every tick of countdown timer, but I want to close notification when Stop button is pressed. I used notificationmanager.cancel(id) but notification is closed and re opened again. What wrong I did? Here is my code:
private void startButtonClick() {
try {
time = Integer.parseInt(timeInMinutes.getText().toString());
if (time == 0) {
throw new NumberFormatException("Time can't be lower than 1");
}
startButton.setVisibility(View.INVISIBLE);
pauseButton.setVisibility(View.VISIBLE);
timeInMinutes.setVisibility(View.INVISIBLE);
countDownTextView.setVisibility(View.VISIBLE);
final NotificationCompat.Builder mBuilder =
new NotificationCompat.Builder(this)
.setSmallIcon(R.mipmap.ic_launcher)
.setLargeIcon(BitmapFactory.decodeResource(getApplicationContext().getResources(), R.mipmap.ic_launcher))
.setContentTitle("Timer")
.setContentText("12312312");
notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
new CountDownTimer(time * 60000, 500) {
public void onTick(long millisUntilFinished) {
if (isCanceled) {
cancel();
buttonsVisibility();
isCanceled = false;
}
int minutes = (int) (millisUntilFinished / 1000) / 60;
int seconds = (int) (millisUntilFinished / 1000) % 60;
countDownTextView.setText("Time left: " + String.format(Locale.getDefault(), "%02d:%02d", minutes, seconds));
mBuilder.setContentText("Time left: " + String.format(Locale.getDefault(), "%02d:%02d", minutes, seconds));
notificationManager.notify(3, mBuilder.build());
}
public void onFinish() {
turnOffBluetooth();
turnOffWiFi();
turnOffAudio();
turnOnSilentMode();
buttonsVisibility();
notificationManager.cancel(3);
}
}.start();
}
catch (NumberFormatException e){
Toast.makeText(getApplicationContext(), "Enter time. Only numbers!", Toast.LENGTH_SHORT).show();
}
}
private void pauseButtonClick() {
Toast.makeText(getApplicationContext(), "Timer off", Toast.LENGTH_LONG).show();
startButton.setVisibility(View.VISIBLE);
pauseButton.setVisibility(View.INVISIBLE);
isCanceled = true;
NotificationManager notificationManager = (NotificationManager)getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.cancel(3);
}
Even though you have canceled the timer you haven't finished the method so it will continue execution to avoid that you can try this
if (isCanceled) {
cancel();
isCanceled = false;
} else {
int minutes = (int) (millisUntilFinished / 1000) / 60;
int seconds = (int) (millisUntilFinished / 1000) % 60;
mBuilder.setContentText(
"Time left: " + String.format(Locale.getDefault(), "%02d:%02d", minutes, seconds));
notificationManager.notify(3, mBuilder.build());
}
