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
当前回答
dataWebView.setWebViewClient(new VbLinksWebClient() {
@Override
public void onPageFinished(WebView webView, String url) {
super.onPageFinished(webView, url);
}
});
public class VbLinksWebClient extends WebViewClient
{
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url)
{
view.getContext().startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse(url.trim())));
return true;
}
}

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
}
}
String url = "http://www.example.com";
Intent i = new Intent(Intent.ACTION_VIEW);
i.setData(Uri.parse(url));
startActivity(i);
Kotlin溶液
所有答案都是在该url的默认应用程序中打开该url。我想总是在浏览器中打开任何url。我需要一些kotlin的解决方案，并实现了下面的代码。
fun getPackageNameForUrl(context: Context, url: String): String? {
val intent = Intent(Intent.ACTION_VIEW, Uri.parse(url))
val resolveInfo = context.packageManager.resolveActivity(intent, PackageManager.MATCH_DEFAULT_ONLY)
return resolveInfo?.activityInfo?.packageName
}
fun openInBrowser(context: Context, url: String) {
val intent = Intent(Intent.ACTION_VIEW, Uri.parse(url))
val packageName = getPackageNameForUrl(context, "http://")
packageName?.takeIf {
it == "android"
}?.let { intent.setPackage(defaultBrowserPackageName); }
startActivity(context, intent, null)
}
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)
}

简单和最佳实践
方法1：
String intentUrl="www.google.com";
Intent webIntent = new Intent(Intent.ACTION_VIEW, Uri.parse(intentUrl));
if(webIntent.resolveActivity(getPackageManager())!=null){
startActivity(webIntent);
}else{
/*show Error Toast
or
Open play store to download browser*/
}
方法2：
try{
String intentUrl="www.google.com";
Intent webIntent = new Intent(Intent.ACTION_VIEW, Uri.parse(intentUrl));
startActivity(webIntent);
}catch (ActivityNotFoundException e){
/*show Error Toast
or
Open play store to download browser*/
}
