以下是我的代码在主要活动
public class MainActivity extends ActionBarActivity{
private MediaRouteButton mMediaRouteButton;
private MediaRouteSelector mMediaRouteSelector;
private MediaRouter mMediaRouter;
private CastDevice mSelectedDevice;
private MyMediaRouterCallback mMediaRouterCallback;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
if(this.checkGooglePlaySevices(this))
Log.v("cc5zhenhua","googleplayservice okay");
else
{
Log.v("cc5zhenhua","googleplayservice not ok");
//GooglePlayServicesUtil.getErrorDialog(0, this, 0).show();
}
//initialize media cast objects
mMediaRouter=MediaRouter.getInstance(getApplicationContext());
mMediaRouteSelector=new MediaRouteSelector.Builder()
.addControlCategory(CastMediaControlIntent.CATEGORY_CAST).build();
mMediaRouterCallback= new MyMediaRouterCallback();
mMediaRouter.addCallback(mMediaRouteSelector, mMediaRouterCallback);
}
public void onStart() {
super.onStart();
mMediaRouter.addCallback(mMediaRouteSelector, mMediaRouterCallback
);
MediaRouter.RouteInfo route = mMediaRouter.updateSelectedRoute(mMediaRouteSelector);
// do something with the route...
}
@Override
protected void onResume()
{
super.onResume();
mMediaRouter.addCallback(mMediaRouteSelector, mMediaRouterCallback);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
super.onCreateOptionsMenu(menu);
//mMediaRouteButton.setRouteSelector(mMediaRouteSelector);
return true;
}
@Override
public boolean onPrepareOptionsMenu(Menu menu){
getMenuInflater().inflate(R.menu.main, menu);
MenuItem mediaRouteItem = menu.findItem( R.id.action_mediaroute01 );
MediaRouteActionProvider mediaRouteActionProvider =
(MediaRouteActionProvider)MenuItemCompat.getActionProvider(
mediaRouteItem);
mediaRouteActionProvider.setRouteSelector(mMediaRouteSelector);
mMediaRouteButton = (MediaRouteButton) mediaRouteItem.getActionView();
return true;}
public boolean checkGooglePlaySevices(final Activity activity) {
final int googlePlayServicesCheck = GooglePlayServicesUtil.isGooglePlayServicesAvailable(
activity);
switch (googlePlayServicesCheck) {
case ConnectionResult.SUCCESS:
return true;
default:
Log.v("cc5zhenhua","test"); }
return false;
}
private class MyMediaRouterCallback extends MediaRouter.Callback
{
@Override
public void onRouteSelected(MediaRouter router, RouteInfo info) {
mSelectedDevice = CastDevice.getFromBundle(info.getExtras());
String routeId = info.getId();
Log.v("cc5zhenhua", "MainActivity.onRouteSelected");

}
有没有生成错误。 然而，当我运行的主要活动，媒体路线按钮不能在所有的点击。 请指教任何地方我错过了什么？ 谢谢！
发布新的SDK之前，我的Chromecast列入白名单临时用户与APPID。 我不能使用APPID为控制类别要么，它抛出不valida的appid例外。
我投设备也可用于在我的电脑Chromecast扩充。
