同样代码在，PC Chrome里面运行是OK的。
在Android 4.4.4 webview中运行，报错：
Request has been terminated
Possible causes: the network is offline, Origin is not allowed by Access-Control-Allow-Origin, the page is being unloaded, etc.

运行到

realtime.createIMClient(clientid).then(function(clientObj) {
		client = clientObj;
		clientReady = true;
		ClientMsgHander();
	}).catch(error)
