I'll try my best to convey what my problem is, but I am having issues updating a clients application that is currently in the Play Store. The old version of the app was created by different developers.
The previous version of the app by the looks of things was created using Adobde Air, I don't have any experience at all with Adobe Air, so not too sure about the signing process with the APKs.
My new version is a new project (with same package name) created in Android Studio.
I obviously need to sign the release APK with the same certificate as the previous version. Can I do this via Android Studio using the Build > Generate Signed APK?
Will the previous developers have to provide a .keystore or .jks file? as I said i'm not sure how the signing process works when using Adobe Air.
Any help would be appreciated.
Thanks.
If you can build an apk and have the original keystore file you can sign it via the command line.
Take a look here:
You uploaded an APK that is not zip aligned error
You'll need to do the jarsigner step first, then the zipalign on the resulting file. 4 works for me as the alignment value.
