Google Photos Reactive API Client

Reactive (RxJava2) API client for Google Photos (formerly known as Picasa)

based on work done at android-picasa-client by Daniel Ciao.

Dependency

Add this in your root build.gradle file (not your module build.gradle file):

allprojects {
	repositories {
		maven { url "https://jitpack.io" }
	}
}

Add this to your module's build.gradle file:

dependencies {
    compile 'com.github.yosriz:RxGooglePhotos:{latest-version}'	
}

Usage

• construct GooglePhotosClient object, and delegate onActivityResult event :

  @Override
  protected void onActivityResult(int requestCode, int resultCode, Intent data) {
      super.onActivityResult(requestCode, resultCode, data);
  
      googlePhotosClient.onActivityResult(requestCode, resultCode, data);
  }

• GooglePhotosClient relies on Google Sign-In mechanism to get access to user photos. use GooglePhotosClient object to create a service, either sliently (if already signed in), or non-sliently (to display account selection and permission dialogs) :

  googlePhotosClient.createServiceSilently(activity)
               .observeOn(AndroidSchedulers.mainThread())
               .subscribe(googlePhotosService -> {
                   //use googlePhotosService to perform queries
               }

• createServiceSilently/createServiceWithSignIn methods will return GooglePhotosService with proper authorization on success, GooglePhotosService is the API gate to perform Google Photos queries.

• for switching user/sign out, use GooglePhotosClient.signout().

Sample

see Sample project for full demo.

Create Google API OAuth credential

In order to be able to sign in using Google credentials, an app must be registered through Google Dev Console, using key store that app was signed with. see this SO answer for required steps.

Note

This library using Picasa Web Albums Data API, as Google stated that Picasa is retiring, any breaking changes can be happen in the future.
