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);	}
