android视频通话不显示图像

接收方和发起方的各自和对面的图像都没有，
但是通话接通了，声音是可以听到的，就是图像没显示
发起方的代码

private EMLocalSurfaceView localSurface;

    private EMOppositeSurfaceView oppositeSurface ;

    @Override

    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_bo);

        localSurface = (EMLocalSurfaceView) findViewById(R.id.b_localSurface);

        oppositeSurface = (EMOppositeSurfaceView) findViewById(R.id.b_oppositeSurface);



        EMCallManager.EMVideoCallHelper callHelper = EMClient.getInstance().callManager().getVideoCallHelper();

        

        try {

            EMClient.getInstance().callManager().makeVoiceCall("5819bb47a0bb9f00588f339a");

            EMClient.getInstance().callManager().setSurfaceView(localSurface, oppositeSurface);

        } catch (EMServiceNotReadyException e) {

            // TODO Auto-generated catch block

            e.printStackTrace();

            Log.i("immc","e"+e.getErrorCode()+e.toString());

        }

接收方的代码：

localSurface = (EMLocalSurfaceView) findViewById(R.id.localSurface);

        oppositeSurface = (EMOppositeSurfaceView) findViewById(R.id.oppositeSurface);

        EMClient.getInstance().callManager().switchCamera();

        /**

         * 接听通话

         * @throws EMNoActiveCallException

         * @throws EMNetworkUnconnectedException

         */

        try {

            EMClient.getInstance().callManager().answerCall();

        } catch (EMNoActiveCallException e) {

            e.printStackTrace();

        }

        EMClient.getInstance().callManager().setSurfaceView(localSurface, oppositeSurface);
