I am trying to update my app from Nougat API level 26 to Android Pie, API level 28. I set my targetSdkVersion to 28, and compileSdkVersion to 28. I have also updated all my support library versions to latest (which is also 28). Here is my app's gradle build file:
The build works fine and I have tested it out on a API level 28 virtual device, Nexus 5X API 28 and Pixel 2 XL API 28.
However, when I upload it to Google Play Console it shows this:
I know that this will mean that there won't be any changes to which devices are compatible (because the previous version was also up to API level 26).
I have tried searching online but I could not find an answer. Most of the search results tell you to update your targetSdkVersion, support library versions and compileSdkVersion to 28, which I have already done. The other half are about the difference between minSdkVersion and targetSdkVersion.
What am I doing wrong here?
