Android growth Diary-app signature and packaging

The meaning of the signature:

1. To ensure that each application developer is legally

2. Prevent some people from using the same package name to confuse the replacement of the installed program, resulting in some malicious tampering

3. Guarantee the consistency of each version we release

(such as Automatic Updates will not be installed because of inconsistent versions)

--

Way:

(There will be an operation to add a signature to the program in next operation.)

Ps: A signature file and APK will be generated at the end of the signature, and the next time the program is upgraded, the signature file can be used
