[Android] Don't hard set play services version

[Ehesp]

Hello,

Bear in mind, I'm not to clued up to Android yet...

I keep running into the same issue whereby my build fails due to "Multiple dex files". The cause of this is conflicting play-services versions across multiple libs. This library hard sets the dep to 9.8.0.

Other libs seem to only set it to "whatever is latest", e.g: https://github.com/zo0r/react-native-push-notification/blob/master/android/build.gradle#L44 & https://github.com/idehub/react-native-google-analytics-bridge/blob/master/android/build.gradle#L21

The only way I can fix these errors is by either:

1. Adding this to my own build.gradle:

dependencies {
    compile ('com.google.android.gms:play-services-gcm:9.8.0') {
      force = true;
    }
    ...

2. Going into node_modules, and changing the line to compile 'com.google.android.gms:play-services-base:+'.

Didn't want to make a PR since I'm not sure if this will have any repercussions?

That should be fine. Make a PR when you get a chance. I think that sounds like a great idea.

Actually, what do you think about doing this for all Firestack dependencies?

[Ehesp]

I supposed the only issue is if the lib isn't kept up to date with say the latest firebase SDK, then users are going to have weird issues.

[auser]

Good point. I agree.

Closing as fixed on v3 branch.
