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

根据Mark B的回答和以下评论：
protected void launchUrl(String url) {
Uri uri = Uri.parse(url);
if (uri.getScheme() == null || uri.getScheme().isEmpty()) {
uri = Uri.parse("http://" + url);
}
Intent browserIntent = new Intent(Intent.ACTION_VIEW, uri);
if (browserIntent.resolveActivity(getPackageManager()) != null) {
startActivity(browserIntent);
}
}

来自Anko库方法
fun Context.browse(url: String, newTask: Boolean = false): Boolean {
try {
val intent = Intent(Intent.ACTION_VIEW)
intent.data = Uri.parse(url)
if (newTask) {
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK)
}
startActivity(intent)
return true
} catch (e: ActivityNotFoundException) {
e.printStackTrace()
return false
}
}
Intent getWebPage = new Intent(Intent.ACTION_VIEW, Uri.parse(MyLink));
startActivity(getWebPage);
其他选项使用Webview在同一应用程序中加载Url
webView = (WebView) findViewById(R.id.webView1);
webView.getSettings().setJavaScriptEnabled(true);
webView.loadUrl("http://www.google.com");
String url = "https://www.thandroid-mania.com/";
if (url.startsWith("https://") || url.startsWith("http://")) {
Uri uri = Uri.parse(url);
Intent intent = new Intent(Intent.ACTION_VIEW, uri);
startActivity(intent);
}else{
Toast.makeText(mContext, "Invalid Url", Toast.LENGTH_SHORT).show();
}
该错误是由于URL无效而发生的，Android OS无法找到数据的操作视图。因此，您必须验证URL是否有效。
试试这个OmegaIntentBuilder
OmegaIntentBuilder.from(context)
.web("Your url here")
.createIntentHandler()
.failToast("You don't have app for open urls")
.startActivity();
