Реализация звукового уведомления приложения в Android

0 голосов
/ 27 декабря 2018

Целью приложения является воспроизведение некоторых радиостанций с помощью потоковой передачи URL с использованием exoplayer.Возникла проблема в том, что, когда приложение работает и запускается уведомление, есть 2 разных потока, воспроизводимых одним нажатием моей кнопки из интерфейса радио и одним уведомлением.

Мой вопрос заключается в том, как сделать так, чтобы при нажатии кнопки на пользовательском интерфейсе он также изменял поток в проигрывателе уведомлений.

PS Я попытался импортировать один проигрыватель, однакодоказано из mainactivity.java, назовем его статическим, однако это приводит к утечке памяти и остановке потока в службе переднего плана.

Я использовал здесь messagesPlayerManager (exoplayer): https://www.youtube.com/watch?v=svdq1BWl4r8

После некоторых исследований я нашел ответ.Для всех, кто хочет привязать основное действие к сервису.

В этом процессе я использовал этот метод для привязки игрока к сервису: 

public SimpleExoPlayer getPlayer1()
{
    return player1;
}

Затем вызовите его в своем основном:

player = myServices.player1;
...
