Convert android files to base64 and Base64 files

File Transfer is required in the project. The best way to facilitate transmission is to convert the file into a base64 string, and then convert the base64 string into a byte stream and save it in the file. However, this method is simple, but it still needs to be selected based on actual needs. The disadvantage is that it cannot be converted into too many files. Too many files will cause efficiency problems. I did not do any in-depth research or practical tests. If you are interested, you can perform in-depth research and testing on your own.
