作者判断时候是判断X.0版本号的（X为1-9），而新机（如 华为mate20）安卓版本号为9，并非9.0，故判断不到，所以导致生成不了二维码。故将n方法里改为如下图代码即可

改一下版本号的正则表达式不是更简单吗？
var aMat = sAgent.toString().match(/android ([0-9].[0-9])/i);
这句话改为
var aMat = sAgent.toString().match(/android (([0-9]).?[0-9]?)/i);

@xiaoxiaoyisheng 当时没管那么多。🤔

@zc422 是的，就安卓9就不行，其他都行，二维码是正常生成了的，之前也是正常，升级了系统就凉了

@XuZpeng 方便发代码来看下吗

js:
new QRCode($('.qrcode')[0], {
text: "https://xcx.hexiaoxiang.com/cup_race?refer_id=" + refer_id + "&record_id=" + record_id,
width: 128,
height: 128
});

html:

@zc422
function _getAndroid() {
var android = false;
var sAgent = navigator.userAgent;

	if (/android/i.test(sAgent)) { // android
		android = true;
		var aMat = sAgent.toString().match(/android ([0-9].?[0-9]?)/i);
		
		if (aMat && aMat[1]) {
			android = parseFloat(aMat[1]);
		}
	}
	
	return android;
}

源码我都试了还是不行。。

作者为啥不把修复过的代码添加到仓库里，我看仓库里的代码还是旧的。

@XuZpeng 作者应该没有维护了，你的图片是放在画布里还是ing里

@blue7cat 估计是布局问题，你可以试下长按你步骤图片的左上角会出来识别二维码。然后百度查下微信识别二维码的机制调整下就好了

如果将来有 Android 10 的话这个正则就失效了，建议使用 /android ([0-9]+\.?[0-9]?)/i

安卓10和10以上无法画出二维码，因为作者的正则过时了，当时作者写表达式匹配的时候手机还没有出道安卓10以上
qrcode.js _getAndroid 方法里面的正则判断改为：var aMat = sAgent.toString().match(/([aA])ndroid ([0-9.]*)/i);
