1.2: the manifest. XML is as follows: (note contains android. The intent. The category. The LAUNCHER)

1.3: After running the effect, you can see the screen shot of the phone (you can see there is a launcher (CP3))

2: we can’t see with android. Intent. The category. The effect of the project after the operation the LAUNCHER
2.1: project name as

2.2: the manifest. XML is as follows: (note that there is no android. The intent. The category. The LAUNCHER)
