Question

这个主题有时会弹出，但是我无法正常工作。我的应用程序曾经用于处理媒体按钮，但是Android 5.0之后的API发生了变化，它需要使该应用程序适应“捕获”蓝牙按钮并以“我的方式”处理它们。

我做了很多搜索，发现：

        final MediaSession session = new MediaSession(this, "spy tag");

    session.setCallback(new MediaSession.Callback() {
        @Override
        public boolean onMediaButtonEvent(final Intent mediaButtonIntent) {
            Toast.makeText(me, "on media button event", Toast.LENGTH_SHORT);
            Log.i("TAG", "GOT EVENT");
            return super.onMediaButtonEvent(mediaButtonIntent);
        }

    });

    session.setFlags(MediaSession.FLAG_HANDLES_MEDIA_BUTTONS |
            MediaSession.FLAG_HANDLES_TRANSPORT_CONTROLS);

    PlaybackState state = new PlaybackState.Builder()
            .setActions(
                    PlaybackState.ACTION_PLAY | PlaybackState.ACTION_PLAY_PAUSE |
                            PlaybackState.ACTION_PLAY_FROM_MEDIA_ID | PlaybackState.ACTION_PAUSE |
                            PlaybackState.ACTION_SKIP_TO_NEXT | PlaybackState.ACTION_SKIP_TO_PREVIOUS)
            .setState(PlaybackState.STATE_PLAYING, 0, 1)
            .build();
    session.setPlaybackState(state);

    session.setActive(true);

但是...仍然不起作用。每当我按下任何媒体按钮时，我都会在Logcat中得到它：

，我的应用程序未收到任何回调。我想念什么？
