问题
I have developed three different versions(as different projects) of an app(large,normal,small). How can I upload them as a single app with multiple apk's. Do I need to change package names? How about Keystore? Do I need to use same keystore or different keystores for different versions. And what about version number? Do the names of apk's matter?
回答1:
Rules for multiple APKs see the rules
All APKs you publish for the same application must have the same package name and be signed with the same certificate key.
see also other rules as well ......
To publish multiple APKs for the same application, you must enable Advanced mode in your application's APK files tab (as discussed in the previous section). Once in advanced mode, you can upload, activate, then publish multiple APKs for the same application.
