AirTube

AirTube is an easy to use networking library for Android and Java creating a distributed peer-to-peer overlay mesh network with service discovery and asynchronous message-oriented end-to-end connectivity. By combining these three main features into a small and dedicated library, AirTube frees application developers from worrying about networking details like topologies, IP addresses and port numbers, and simply lets them discover "services" and receive data from it, be it local, remote or anywhere in the global AirTube overlay mesh "cloud".

Allthough AirTube is a generic networking library for Java, it is optimized for Android mobile devices and the transmission of real-time multimedia data like streaming audio and video.

AirTube is an Open Souce project and licensed under the LGPL.

Key Features

Distributed Service discovery by "name" and JSON description
Distributed Peer-to-peer overlay mesh network independent of IP addresses
Non-blocking asynchronous message-oriented networking optimized for multimedia data
Integration with Computer Vision libraries and algorithms
Efficient and small library (~250KB) for Android and any Java platform

Developments status

AirTube was developed internally over a period of about two years and is now being presented to the public as Open Source. The main features "service discovery", "mesh protocol" and "asynchronous networking" are functional, and some effort has been made to provide a stable API which works well as an Android service and in "pure" Java. We still have ambitious plans to move forward by implementing the following features:

End-to-end encryption
More advanced service matching and lookup
Additional service types, like "Request-Response"
Additional transmission types like "delayed delivery" (store & forward)
...

We welcome contributions and are maintaining the project as open source.

Requirements

Android: Version 4.0.4 or higher
Java: Version 1.6 or higher
No dependency on other libraries

Services integrated with AirTube

AirTube is a general purpose networking library but we have developed it with a focus on multimedia data and computer vision. As such we provide the following "services" as part of AirTube:

Real-time video stream sending (encoding) from Android with H264 codec
Video receiving (decoding) on Android and PC
Real-time audio stream using the Opus codec (optional Speex, G711, AAC) including a Jitter Buffer implementation and echo cancellation
OpenCV processing on the sender and/or receiver side
Face detection
...

DiscreteSeekBar

DiscreteSeekbar is an android implementation of the Discrete Slider component from the Google Material Design Guidelines.

Range Bars

android-material-icons

android-material-icons allows you to include any of the Material Design icons in your texts, your ActionBar, and even in your EditTexts. Icons are infinitely scalable, and customizable with shadows and everything you can do on texts.

AndroidProgressLayout

If you tired from wrapping your Views with RelativeLayout to add ProgressBar then this small view will help you. It extends from RelativeLayout, so you shouldn't add additional layouts to use it, just think about it as a RelativeLayout with auto added ProgressBar.
