Android silent mode enables in depth analysis of bulk installation and uninstallation applications

Some time ago, I made a small application to install and uninstall the application in batch. Because the part of API of the uninstall and uninstall application is hidden, I must download the Android system source code under ubuntu, and compile it to generate APK files using MM command. In fact, it is also difficult.
The idea is that there is an PackageInstaller application in the XX/packages/apps directory, and this application does the installation and uninstallation on the Android machine. However, it does not have the function of batch installation and uninstallation. If you want to add the function of batch installation and uninstallation in your own application, it is actually very simple, just refer to the installation and uninstallation code in PakcageInstaller and add a loop. However, it is important to note that the Android.mk file in PackageInstaller must be copied during compilation and changed to the project directory name.
Well, without further ado, here's the key code
1. Android.mk
2. PakcageInstaller.java file (key code)
3. Don't forget to add permissions
The above code was compiled in SDK of Android2.1 and installed and uninstalled the application in the correct batch
