Java implements silent installation of apk
Silent installation is to secretly install an application on the mobile phone, that is, to block the confirmation box, and through reflection
I can only write the main code, which is used in Linux compilation, because the silent installation needs to call system services, and I have been working on it for a long time to compile under the source code
