hotstu opened a new issue #2884: require callbacks when WXSDKEngine.initialize complete
URL: https://github.com/apache/incubator-weex/issues/2884
 
 
   how to reduce: 
   1. init engine in the Applicaiton 
   ```
           InitConfig config = new InitConfig.Builder()
           WXSDKEngine.initialize(this, config);
   ``` 
   it seems the init method above contains async method call :
   ```
   WXBridgeManager.getInstance().post(new Runnable() {
   ...
   }
   ```
   
   so the developer do not know when dit the  `WXSDKEngine` really complete init, if you load page  too quick, you just get an error
   ```
                   mWXSDKInstance.renderByUrl(pageName, bundleUrl, null, null, WXRenderStrategy.APPEND_ASYNC);
   
   ```
   ```
   E/MainActivity: -1001 degradeToH5|createInstance fail|wx_create_instance_error isJSFrameworkInit==false reInitCount == 1
   ```
