• I have google-services.json in "platforms\android\ " path.
• I have installed latest “Google Play Service”, “Google Repository” & “Android Support Repository” in Android SDK.
• I have tried using :

     compile 'com.google.android.gms:play-services:9.0.0'

and

     compile 'com.google.android.gms:play-services:9.2.0'

then, I get issues like:

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':processF0F1F2F3F4F5F6F7DebugGoogleServices'.
> Please fix the version conflict either by updating the version of the google-services plugin (information about the latest version is available at https://bintray.com/android/android-tools/com.google.gms.google-services/) or updating the version of com.google.android.gms to 9.2.0.

What solved for me was look which version the nativescript-plugin-firebase and set the same for the file app/App_Resources/Android/app.gradle

1. Click here and then follow the “this version” link; there you’ll see something like this: def firebaseVersion = "11.4.2" 2)Now, open app/App_Resources/Android/app.gradle and put this inside defaultConfig: project.ext { googlePlayServicesVersion = "11.4.2" }

Hope that helps!

What I’m reading all over the interwebs is that one should (unfortunately) avoid using + in the compile .. play-services command.

Armed with that bit of information I just verified this works with both plugins installed:

First remove/add the platform folder:

• tns platform remove android
• tns platform add android
• Re-add the google-services.json and alter the build.gradle script (see this plugin’s readme)

Alter the Maps plugin to include the same version as the Firebase plugin:

• Open node_modules/nativescript-google-maps-sdk/platforms/android/
• Replace that + by 9.2.0

That should build nicely. If so I will alter the readme and refer to this issue.
