微信android分享開發

1、等到微信開放平臺上申請Android應用，

2、在應用中設置包名與簽名

注意：這裏的簽名必有要去掉冒號後再保存

準備工作完成後就是編碼了

		IWXAPI msgApi = WXAPIFactory.createWXAPI(paraentActivity,
				Constants.APP_ID, true);
		msgApi.registerApp(Constants.APP_ID);
		WXWebpageObject webpage = new WXWebpageObject();
		webpage.webpageUrl = "http://feq.vanmicro.com/UI/html/tip.html";
		WXMediaMessage msg = new WXMediaMessage(webpage);
		msg.title = "歡迎加入芙恩祺";
		msg.description = "歡迎加入芙恩祺";
		// 這裏替換一張自己工程裏的圖片資源
		msg.setThumbImage(thumb);

		SendMessageToWX.Req req = new SendMessageToWX.Req();
		req.transaction = String.valueOf(System.currentTimeMillis());
		req.message = msg;
		req.scene = flag == 0 ? SendMessageToWX.Req.WXSceneSession
				: SendMessageToWX.Req.WXSceneTimeline;
		msgApi.sendReq(req);
