(go) Launch a third-party apk app from an android apk

Launch a third-party apk app from Android apk

We are in the development, often encounter in an apk to run another apk, just like our windows, to make a shortcut like, how to do it?

The core of the problem is that we have to get the third-party APK package name and class name, both of which are critical! For example, I do test QQ apk,package name is Com.tencent.pad.qq,class name is com.tencent.pad.qq.login.QQLoginActivity. Booting from one apk to another apk, of course, is also done by sending intent. Here are a few simple steps:

1, in order to intuitive or build an icon is better. ImageButton controls are available on Android. It is defined in XML as follows:

[HTML]View Plaincopy

1. <ImageButton android:id="@+id/startqq"
2. android:layout_width="85dip"
3. android:layout_height="54dip"
4. android:layout_margintop="20dip" />

2, register the message processing function. That is, when you click on the icon, what to do to respond. The registration code is as follows:

[Java]View Plaincopy

1. private ImageButton Mstartqqbutton;
4. Mstartqqbutton = (ImageButton) Findviewbyid (R.ID.STARTQQ);
5. Mstartqqbutton.setonclicklistener (Mstartqqlistener);

3, prepare intent, send intent. The code is as follows:

[Java]View Plaincopy

2. Private View.onclicklistener Mstartqqlistener = new View.onclicklistener () {
4. public void OnClick (View v) {
6. if (localService = = null) return;
8. Localservice.reqmusicexit ();
12. Intent mintent = new Intent ();
14. ComponentName comp = new ComponentName ("Com.tencent.pad.qq", "com.tencent.pad.qq.login.QQLoginActivity"  );
16. Mintent.setcomponent (comp);
18. Mintent.setaction ("Android.intent.action.VIEW");
20. StartActivity (mintent);
22. Finish ();
24. }
26. };

This is just an example, mastered this method, we can develop a similar Windows shortcut icon bar, it can be arbitrary, to develop products that customers like. By the way, I would like to say, this approach must be in the code of the APK application to customize, such as in the launcher, or the development of their own apk.
