У меня есть приложение для записи экрана, оно не работает на android версии 10. Насколько я понимаю, это связано с изменениями конфиденциальности, действующими в Android 10. Я добавил разрешение <uses-permission android:name="android.permission.FOREGROUND_SERVICE" /> в в моем файле манифеста добавлен тег android:foregroundServiceType="mediaProjection" в службу и вызывается метод startForeground()
Notification.Builder builder = new Notification.Builder(getApplicationContext(), "333")
.setContentTitle(getString(R.string.app_name))
.setContentText("Record")
.setAutoCancel(true);
Notification notification = builder.build();
startForeground(123, notification);
перед вызовом метода .getMediaProjection(), но мое приложение по-прежнему выдает ошибку точно
