Does anyone know what could be the problem? I have set my directories properly as well.

[pundirsumit]

Okey i've fixed the issue by changing the line in build.gradle file present at extern/UnifiedNlp/unifiednlp-compat/build.gradle:

compileClasspath += project.rootProject.files("$sdkDir/platforms/android-25/android.jar") to
compileClasspath += project.rootProject.files("$sdkDir/platforms/android-27/android.jar").

Thanks heaps! Solved my build issue.

For reference, this appears to have been fixed in https://github.com/microg/android_packages_apps_UnifiedNlp/pull/159.

It seems that this fix is not being applied because the git submodule was never updated when the above PR was merged in. I have opened the PR https://github.com/microg/android_packages_apps_GmsCore/pull/568 to fix this.
