#### 开发xmpp中发现,flutter 有限功能还是无法实现的,就需要原生功能的实现 ####

    import io.flutter.plugins.GeneratedPluginRegistrant;
    
    import static com.example.wechat.VideoUtils.getLocalVideoThumbnail;
    import static com.example.wechat.VideoUtils.getVideoThumbnail;
    
    
    public class MainActivity extends FlutterActivity {
    
        //通讯名称,回到手机桌面
        private final String CHANNEL_DESKTOP = "android/back/desktop";
        //通讯名称,回到手机桌面
        private final String CHANNEL_VIDEO = "video/img";
    
        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            GeneratedPluginRegistrant.registerWith(this);
            new MethodChannel(getFlutterView(), CHANNEL_DESKTOP).setMethodCallHandler(
                    (methodCall, result) -> {
                        if (methodCall.method.equals("backDesktop")) {
                            result.success(true);
                            moveTaskToBack(false);

                } else {

                }
    
            });
        }
