FAQ

What is this for?
This process is required if your app is on Google Play and signed with the Google Play signature. To upload your app on Catappult, your app’s signature has to be the same on Google Play and on our platform.

I have my app on Google Play but I use my own signature, do I need to do this?
No. If your app is on Google Play but you have your own signature, you do not need to do this process. You can upload your package’s files directly onto our platform. This is only needed if you use the Google Play signature.

Why do I download the .apk for 4 different devices only?
The specific devices mentioned above (OPPO Find X2, Xiaomi MI 9 SE, Samsung Galaxy A10, Samsung Galaxy Tab A7) are enough for you to cover all device-specific APKs you may need. You don’t have to download all the available devices and you can use different devices if you would like to. This is just our recommendation.

My app does not have splits, do I have to download a different APK for each device?
No. The process is the same either you have .obb files or not. However, if your app does not have any splits, instead of downloading each device-specific APK, you download the “Distribution APK” in the Assets section.

My app has .obb files, do I need to do anything to them?
No. There is no need to do anything.

My app has IAPs, how do I sign and use the One-Step Payment (OSP) billing method?
If your app has In-App purchases, you have to follow the OSP procedure before uploading your file in the Google Play Console. The file you upload on Google Play to get the Google Play signature has to already have OSP billing method integrated.
