Servant: Serving you GoogleApiClients so you don't have to worry about them

Servant will create and manage GoogleApiClient from Google Play Services for you so you can focus on the important actions and requests you want to perform with them.

Servant is especially useful if you want to use the GoogleApiClients in a reactive manner with RxJava.


To use Servant in your project, add the library as a dependency in your build.gradle file:

dependencies {
    compile 'com.mtramin.servant2:servant:'

To make it easier to recognize which version of Google Play Services is used Servants version number will always begin with the used Google Play Services version. It is recommended to always use the version of Servant that matches the version of the Google Play Services you use in your application.


This libraries minSdkVersion is 15.


Depending on your usage of the GoogleApiClients you might also have to declare some permissions in your AndroidManifest.xml. Remember that from Android Marshmallow (API 23) you will have to support runtime permissions for those

Using Servant

Servant serves you GoogleApiClients in multiple formats:

  • With Actions as callbacks
  • Observable
  • Single
  • Completable

With action Callbacks:

Servant.actions(this, LocationServices.API,
        googleApiClient -> Log.e("Servant", "have action client"),
        throwable -> Log.e("Servant", "error in action client", throwable)

Observable client:

Servant.observable(this, LocationServices.API)
                googleApiClient -> Log.e("Servant", "have observable client"),
                throwable -> Log.e("Servant", "error in observable client", throwable)

To use Servant to serve you GoogleApiClients as Single or Completable, simply call

Servant.single(/* implement GoogleApiClientSingle */)
Servant.completable(/* implement GoogleApiClientCompletable */)


![Method count]( count-core: 130 | deps: 21733-e91e63.svg)

Servant brings the following dependencies:

  • RxJava (v2.x)
  • Google Play Services (base) which provides GoogleApiClient

Due to the Google Play Services dependency also the method count of the library seems quite high. However since you will include Google Play Services in your application either way this does not really affect your method count. Servant only relies on the Google Play Services base package to have as little impact as possible.

In total Servant itself has a method count of below 150 methods.
