Android Internal launch other apps, as well as open the designated QQ chat interface

There are several ways to open a third-party app in your own app, here's an example:

To open as an example, if you need to know the Open app package name, generally a release version of the application, the package name will not easily change, but, open QQ will pay attention to, after all, QQ release version has not less than 4 versions.
Intent Intent = Getpackagemanager (). Getlaunchintentforpackage ("com.tencent.mm");  StartActivity (Intent);    

　　

you can jump from a third-party app to QQ interface, and can enter the specified QQ number of the chat interface (can be a stranger QQ number).

Android:

String url= "mqqwpa://im/chat?chat_type=wpa&uin=1642084864"; StartActivity (new Intent (Intent.action_view, Uri.parse (URL)));
the specified  QQ number only needs to modify   the value after UIn. 

Ios:

UIWebView *webview = [[UIWebView alloc] Initwithframe:cgrectzero]; Nsurl *url = [Nsurl urlwithstring:@ "Mqq://im/chat?chat_type=wpa&uin=123456&version=1&src_type=web"]; Nsurlrequest *request = [Nsurlrequest requestwithurl:url];webview.delegate = self; [WebView Loadrequest:request]; [Self.view Addsubview:webview];
