The error was created by android.content.pm.PackageParser , which compares the android:minSdkVersion and android:targetSdkVersion attributes of the uses-sdk element of AndroidManifest.xml in the APK file against the SDK version of the device or emulator. The SDK version on the device has to be greater than that required by android:minSdkVersion .
In my case, since I built the package with AOSP, the target emulator has to be AOSP also. This is the relavant section in AndroidManifest.xml :
<uses-sdk android:minSdkVersion="AOSP"

And the relevant section in android.content.pm.PackageParser :
