Google Workspace Mobile APIs for Android and iOS

Although we recommended that you call Google Workspace APIs from a server using server-side authentication, these APIs can also be called using the Android or iOS SDKs.

Follow the following guides to setup an Android or iOS project with a Google Workspace API.

Android

Android devices can call Google Workspace APIs using the Google API Client Library for Java.

Prerequisites

Prepare the Project

In your Android project, include a build.gradle file with dependencies such as these:

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:25.0.1'
    compile 'com.google.android.gms:play-services-auth:15.0.1'
    compile 'pub.devrel:easypermissions:0.3.0'
    compile('com.google.api-client:google-api-client-android:1.23.0') {
        exclude group: 'org.apache.httpcomponents'
    }
    compile('com.google.apis:google-api-services-<API>-<VERSION>') {
        exclude group: 'org.apache.httpcomponents'
    }
}

Be sure to replace the API and VERSION with the Google Workspace API and version. For example, the Google Slides API would have the target compile 'com.google.apis:google-api-services-slides:v1-rev294-1.23.0'.

Once the service is authenticated, executing the API call is the same as shown in any of the Google Workspace Java quickstarts.

iOS

iOS devices can call Google Workspace APIs using the Google APIs Client Library for Objective-C for REST.

Prerequisites

To use Google Workspace APIs with the iOS Client Library for Objective-C, you'll need:

  • A Google account.
  • Xcode 8.0 or greater.
  • CocoaPods dependency manager.

Prepare the Project

Create a Podfile for an Xcode project would be something like this:

platform :ios, '8.0'
target 'QuickstartApp' do
    pod 'GoogleAPIClientForREST/Sheets', '~> 1.2.1'
    pod 'GoogleSignIn', '~> 4.1.1'
end

In this example we used Sheets, but the API could be any of the services listed in the Google API Objective-C Client for REST.

Full examples of using the Calendar API and Drive API can be found in the Google APIs Objective-C Client repo's Examples folder.
