Copying this answer from this Github issue comment from Trent Gardner, since anything else didn't work for me:

Fix for the Facebook plugin was to force the Facebook SDK to version 4.25.0.

cordova plugin add cordova-plugin-platform-replace

Then add to your config.xml

<platform name="android">
  <replace-string file="project.properties" find="regex:com\.facebook\.android\:facebook-android-sdk\:[\+0-9\.]+" replace="com.facebook.android:facebook-android-sdk:4.25.0" />
</platform>

Finally run cordova prepare android

Works with the latest 1.9.1 version of cordova-facebook-plugin4

Above commands didn't fix my problem.

I change the following line in project.properties in platforms folder

com.google.android.gms:play-services-analytics:11.0.1

to 

com.google.android.gms:play-services-analytics:+

and it's fixed

I have the same issue

(Unable to merge dex Ionic)

when I created the Ionic app. When I run the app the

BUILD FAILED in 11s 37 actionable tasks: 3 executed

error occurred. First I use the following solution but it doesn't work for me but it work for the other I guess.

configurations.all {
    resolutionStrategy {
       force 'com.android.support:support-v4:26.1.0'
    } 
}

Finally this is what helped me to overcome the issue of failing to build the app.

cordova clean android
ionic cordova build android
ionic cordova run android (To re-launch the app)

I did struggle with this issue for 2 days after i used google maps plugin inside my app and i suppose it is because of google-play-service conflicts and i resolved it by install the latest grade release by using this command. Hope it helps anyone else facing this issue
