Things to keep in mind when developing new versions of Android projects

Perhaps before the project is outsourced to do, now need to re-develop a new version, data structure, the interface effect is very different, the novice small white you need to pay attention to a few points.

• Use the same package name and signature. This allows the application to overwrite the installation, and the application on the market can be overwritten.

In the said mobile app overlay installation conditions: 1, the same package name, 2, the same signature, 3, version (Versioncode) is greater than or equal to the overridden application.

• Logins are encrypted in the same way.
• The first version checks the updated interface to submit a new application version.
