这是微信分享的一个重要文件，必须放在“工程全名.wxapi”的目录下面。例如工程名为org.cocos2dx.lua，则WXEntryActivity.java就必须建立在org.cocos2dx.lua.wxapi的目录。

2. 用法代码
private static IWXAPI api = null;
private void sendWeixinImage(int mode,String bigPng){
if(api == null)
{
api = WXAPIFactory.createWXAPI(this,WXEntryActivity.APP_ID);
api.registerApp(WXEntryActivity.APP_ID);
}
WXEntryActivity.sendImageWithAPI(api,this,mode,smallPng,bigPng);
}
private void sendWeixinURL(String png,String desc,int mode){
if(api == null)
{
api = WXAPIFactory.createWXAPI(this,WXEntryActivity.APP_ID);
api.registerApp(WXEntryActivity.APP_ID);
}
WXEntryActivity.sendURLWithAPI(api,png,title,desc,url,mode);
}
