为什么运行起来后，可以检索到设备，选中设备后也无法跨设备调度成功，我有同账号，跟在同一个局域网中，也有打开多设备协同，也给了权限，为什么不管第二个设备有没有安装，就是无法调度起来。是怎么回事，log中也没有看出报什么错，请尽快处理，至少官方demo要跑的起来啊。 06-03 16:54:11.792 19946-19946/com.huawei.maildemo_my W wei.maildemo_m: Can't mmap dex file /data/app/com.huawei.maildemo_my-SyWv_ptJvxLSv_Jon7-G0A==/base.apk!classes.dex directly; please zipalign to 4 bytes.

In the official doc of this codelab Phase 6, it mentioned a challenge to add multiple animations to the img-mixes. But it seems that it was not completed in this repository.
鸿蒙手机优酷App视频流转到鸿蒙pad成功，但是运行DistributedVideoCodelab流转失败。
提示错误为 transmit failed!Please try again later
对应代码为 boolean connectFlag = connectAbility(intent, new IAbilityConnection() { @Override public void onAbilityConnectDone(ElementName elementName, IRemoteObject remoteObject, int extra) { implVideoMigration = VideoMigrationStub.asInterface(remoteObject); try { implVideoMigration.flyIn(startMillisecond); } catch (RemoteException e) { LogUtil.error(TAG, "connect successful,but have remote exception"); } }
@Override
public void onAbilityDisconnectDone(ElementName elementName, int extra) {
disconnectAbility(this);
}
});
if (connectFlag) {
Toast.toast(this, "transmit successful！", TOAST_DURATION);
remoteController.show();
startMillisecond = player.getCurrentPosition();
player.release();
} else {
Toast.toast(this, "transmit failed!Please try again later.", TOAST_DURATION);
}
一个bool值提供的错误信息太少了，如何判断为什么流转失败
