Answer 1

快点去看看。

final Intent intent = new Intent(Intent.ACTION_VIEW).setData(Uri.parse(url));
activity.startActivity(intent);

或..

Uri uriUrl = Uri.parse("http://www.google.com/");   
Intent launchBrowser = new Intent(Intent.ACTION_VIEW, uriUrl);
startActivity(launchBrowser);

Answer 2

我觉得AndroidManifest.xml中的活动缺失如下：

<activity
            android:name="dev.socialnet.server.Server"
            android:label="@string/app_name">

        </activity>

Answer 3

我设法通过从intent中删除包含classname的额外内容来解决问题。就我而言，它是“clazz = com.example.ExampleActivity”。为了删除额外的内容，我在my活动的startActivity方法中执行了此操作。

@Override
public void startActivity( final Intent intent, final Bundle options )
{
    intent.removeExtra( "clazz" );
    super.startActivity( intent, options );
}

仅供参考：我通过覆盖WebViewClient的shouldOverrideUrlLoading从webview打开链接（mailto和http）时遇到了问题。

希望这有助于某人（花了我2.5小时才找到解决方案）。
