java - Android kitkat API 19，Intent.ACTION_VIEW 不起作用

Question

我使用这行代码在手机默认浏览器中打开URL

startActivity(new Intent(Intent.ACTION_VIEW).setData(Uri.parse("http://www.myurl.com")));

现在在 Android KitKat 上，使用 GoogleApi 19 在模拟器设备上运行我的项目，屏幕变黑并出现“浏览器停止工作”错误...

这个新版本和我的代码有什么问题？

这是日志

Answer 1

对我有用

 public static void openBrowser(final Context context, String url)
    {
        if (!url.startsWith("http://") && !url.startsWith("https://"))
        {
            url = "http://" + url;
        }

        Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
        context.startActivity(Intent.createChooser(intent, "Chose browser"));
    }
