DETAILS:

1. Couchbase on Android by Hod Greeley

Couchbase has a mobile NoSQL database stack that's easy to use, yet addresses tough problems to help you build always available apps that sync. This will be a short overview and a tiny bit of code to get you introduced to Couchbase on Android.

Second Presentation:

2. An introduction to Exoplayer by Martin Bonnin

While playing a simple video is quite an easy task with Android builtin Mediaplayer, things can become quite more complicated when looking into the details. Adaptive streaming, fine-grained buffering, offline caching, nice UI transitions, battery usage, etc are all extremely important topics and critical to a 5 stars app. In this talk, Martin will explain how Exoplayer ( https://github.com/google/ExoPlayer [1]), an open source project started at Google, can help playing video more efficiently and in a more flexible way. He will also discuss the pitfalls of playing videos on Android, like choosing between SurfaceView and TextureView and what's new in Exoplayer 2.0

Third Presentation:

3. 360 Video on Android by Tony Constantinides

Description: Tony will outline all the technical features for 360 video on Android. He show video clip created with his Nexus 6P and a cheap fisheye lens and his attempt to stitch together video clips using his framework. He will explain how the video is created, the metadata behind it and a sample 360 player that builds on the Facebook implementation. Come and have fun with 360 video on Android!!
