[Solved] Why does AndroidManifest.xml have invalid targetSdkVersion?

by


Finally I solved it by:
removing:

minSdkVersion 15
targetSdkVersion 28

from gradle.
and adding :

<uses-sdk
    android:minSdkVersion="15"
    android:targetSdkVersion="26" />

to manifest!
It seems slideme.org isn’t up to date…
