Amazon Developers Console - Android - Outdated SDK Version of AppInventor?


I upload my android apps, which I have created with AppInventor also on Amazon. The problem is, that I get the following message:

Your App file uses an outdated SDK version that does not include DRM integration. Select DRM preferences below. If you want to add DRM support in your code, use the Appstore SDK.

I would like to use DRM, but it is not possible with my AI android apps. Does someone please know, how I can use a new version of the SDK? I would like to continue to create my apps in AppInventor. I like it. Thank you very much!
