当我从Sender应用程序连接到CC设备时,自定义接收器通常无法正常启动。
它会加载,但永远不会处于就绪状态。
这是logcat的输出:

如果我在Sender应用程序中断开连接,然后重新连接,Receiver将进入就绪状态,我可以投射内容。
是什么导致这种行为? (它发生的次数多于没有发生,而且非常麻烦!)
一些代码:
(媒体路由初始化)
mMediaRouter = MediaRouter.getInstance(getApplicationContext());
mMediaRouteSelector = new MediaRouteSelector.Builder()
.addControlCategory(
CastMediaControlIntent.categoryForCast(getResources()
.getString(R.string.app_id))).build();
mMediaRouterCallback = new MyMediaRouterCallback();
mDataCastManager = DataCastManager.initialize(this, getResources().getString(R.string.app_id), getResources().getString(R.string.namespace));
mDataCastManager.reconnectSessionIfPossible(this, true, 20);
媒体路径按钮
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.main, menu);
MenuItem mediaRouteMenuItem = menu.findItem(R.id.media_route_menu_item);
MediaRouteActionProvider mediaRouteActionProvider = (MediaRouteActionProvider) MenuItemCompat.getActionProvider(mediaRouteMenuItem);
mediaRouteActionProvider.setRouteSelector(mMediaRouteSelector);
return super.onCreateOptionsMenu(menu);
}
回呼
private class MyMediaRouterCallback extends MediaRouter.Callback {
@Override
public void onRouteSelected(MediaRouter router, MediaRouter.RouteInfo info) {
Log.d(TAG, "onRouteSelected");
// Handle the user route selection.
mSelectedDevice = CastDevice.getFromBundle(info.getExtras());
launchReceiver();
}
@Override
public void onRouteUnselected(MediaRouter router, MediaRouter.RouteInfo info) {
Log.d(TAG, "onRouteUnselected: info=" + info);
teardown();
mSelectedDevice = null;
}
}
如您所见,我的大部分实现来自CastHelloText Android示例应用程序。我已在CCL库中添加了允许轻松进行会话管理的功能,但我认为这是造成此问题的原因。
连接CC设备进行投射时,注释掉DataCastManager似乎会提供更好的结果。
最佳答案
如果使用的是CCL,请停止管理媒体路由器按钮,来自媒体路由器的直接回调,启动接收器等,因为这些都是由CCL处理的。如果您想自己做这些事情,请停止使用CCL。您当前正在以错误的方式混合两种不同的事物。阅读有关CCL的文档可能会有所帮助。
