I am trying to upload my app to Google Play using the developer console. As of a week or so ago they have made it so that each app has a unique key string. You have to use the new developer console to get the key for your app. The problem is that there is apparently no way to upload an expansion file, which my app needs, in the new developer console. How then do I get my key, and get my apk with expansion file uploaded to Google Play?
Uploading an expansion file was simple with the old console all you had to do is upload it at the same time you were uploading the apk file.
What is it that I am missing?
This is a known issue of the Google developer console.
You can't add the expansion file to your first APK.
So if you are uploading for the first time, you will need to generate a second APK with a higher versionCode and upload it again. Only then, you will have the option to add your expansion file in the developer console.
From Google documentation:
Note: If you’re uploading a new app, expansion files can’t be added to the first APK file that you upload.
2018 Answer: The upload dialog for your obb file is hidden on the + sign right to your apk.
It is possible to add the expansion pack (the obb file) in the new Google Play.
When you select an application, you need to switch to "Advanced Mode". Once you've uploaded your apk file, an additional field "Expansion File" will become visible. There you have to upload your obb file. (See Screenshot)
You can now upload an expansion file in the new console, you just have to add an initial dummy .apk. In subsequent uploads, it will let you set the expansion file. You don't have to leave the new view at all. Hope that helps
"The following features are not yet supported in the new Developer Console. If you need to use these features, you can click “switch back” at any time to use the old Developer Console.
- •APK Expansion Files
- •Multiple APK support
- •Announcements
- •IE9 support
- •Partner channel
We’re working on adding these features and many more, so stay tuned!"
For anyone using Apportable to port your iOS builds to Android, you'll need to ensure you have "expansion_files" listed in the FEATURES of your config json file.
Without this, you won't be presented with the option to upload your OBB file(s) after uploading your APK to the Google Play Dev Console.
