Wemall App Store source Android Development MD5 Encryption Tool class

Wemall-mobile is based on the Wemall Android App Store, only need to upload the interface file in the original mall directory to complete the server configuration, the client can be customized modification. This article shares the main code of the Android Development MD5 encryption tool class for technician reference learning.
