如何从内置web浏览器而不是应用程序中的代码打开URL？
我试过了：
try {
Intent myIntent = new Intent(Intent.ACTION_VIEW, Uri.parse(download_link));
startActivity(myIntent);
} catch (ActivityNotFoundException e) {
Toast.makeText(this, "No application can handle this request."
+ " Please install a webbrowser", Toast.LENGTH_LONG).show();
e.printStackTrace();
}
但我有个例外：
No activity found to handle Intent{action=android.intent.action.VIEW data =www.google.com

短代码版本。。。
if (!strUrl.startsWith("http://") && !strUrl.startsWith("https://")){
strUrl= "http://" + strUrl;
}
startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse(strUrl)));

检查您的url是否正确。对我来说，url前面有一个不需要的空格。
Kotlin开发人员可以使用
var webpage = Uri.parse(url)
if (!url.startsWith("http://") && !url.startsWith("https://")) {
webpage = Uri.parse("http://$url")
}
val intent = Intent(Intent.ACTION_VIEW, webpage)
if (intent.resolveActivity(packageManager) != null) {
startActivity(intent)
}
在try块中，粘贴以下代码，AndroidIntent直接使用URI（统一资源标识符）大括号中的链接来标识链接的位置。
你可以试试这个：
Intent myIntent = new Intent(Intent.ACTION_VIEW, Uri.parse("http://www.google.com"));
startActivity(myIntent);
String url = "http://www.example.com";
Intent i = new Intent(Intent.ACTION_VIEW);
i.setData(Uri.parse(url));
startActivity(i);
在Android 11中打开URL链接的新的更好方法。
try {
val intent = Intent(ACTION_VIEW, Uri.parse(url)).apply {
// The URL should either launch directly in a non-browser app
// (if it’s the default), or in the disambiguation dialog
addCategory(CATEGORY_BROWSABLE)
flags = FLAG_ACTIVITY_NEW_TASK or FLAG_ACTIVITY_REQUIRE_NON_BROWSER or
FLAG_ACTIVITY_REQUIRE_DEFAULT
}
startActivity(intent)
} catch (e: ActivityNotFoundException) {
// Only browser apps are available, or a browser is the default app for this intent
// This code executes in one of the following cases:
// 1. Only browser apps can handle the intent.
// 2. The user has set a browser app as the default app.
// 3. The user hasn't set any app as the default for handling this URL.
openInCustomTabs(url)
}
