Error after adding meta data in android manifest


I just installed google maps sdk and added

            android:value="@string/nativescript_google_maps_api_key" />

to androidmanifest and after that i can’t build app.
error is:
FAILURE: Build failed with an exception.

  • What went wrong:
    Execution failed for task ‘:app:processDebugResources’.

Failed to execute aapt

in google map sdk readme i saw this line :
Then, in your AndroidManifest.xml located at app/App_Resources/Android/src/main/AndroidManifest.xml insert into your application tags

but AndroidManifest.xml is in Android folder not in /Android/src/main
