I have tried updating the config.xml file to include: versionCode="10002"
I've created a 'platforms/android/release-signing.properties' file and ran:
phonegap build --release android --versionCode=10002
Nothing seems to make the versionCode=10002 stick. How can I fix this?
I had tried it with both the "android-" prepended and without. As well as with the parameters on separate lines rather than on the same line.
That did not help.
What did end up resolving it for me was creating a new PhoneGap Build app. That was created fine with the new version and I uploaded to the Google Play Store no problem. It seems to be a bug with PhoneGap's inability to update the version number. Too bad.
