getting " 'android:icon' attribute: attribute is not a string value” error while uploading an APK to the play store

Question

Background

After so many hours of my free time, I\'m ready to publish my very first app to the play store, but sadly I\'m having difficulties uploading the signed app.

Answer 1

In my case, the issue was simply that one of my app's dependencies had declared one of their activities to use android:icon="@color/black" in their manifest, instead of using a drawable. You don't get any compilation errors, and the apps works just fine. Only the aapt tool reports the error (or uploading to the Playstore). Note, libraries don't even need android:icon to be declared (they're not an installable app!) but AndroidStudio appears to default all projects to declare one in the manifest.
