(Android™) Upload Media for Google Photos

Demonstrates how to upload a media file (such as a JPG image) that will be placed in a Google Photos album. Uploading is a two-step process:

1. Upload the raw bytes to a Google Server. This doesn't result in any media items being created in the user’s Google Photos account. Instead, it returns an upload token which identifies the uploaded bytes.
2. Use the upload token to create the media item in the user’s Google Photos account. You can choose whether the media should be also added to a specific album.

This example shows step 1.
