Building libjingle for Android

Libjingle is a C++ library used to create peer-to-peer connections for voice-chat applications. It is included in WebRTC and bundled inside the Chromium source repository.
There are a couple of web pages with instructions out there about how to build the library for Android, but none of them seem complete.
This is where this post comes in.

Building GStreamer-1.0-SDK for Android MIPS

GStreamer is a nice SDK with which you can create multimedia applications for a multitude of systems. My concern is primarily Android with RTSP and video playback.
The SDK is already available for Android for a couple of architectures (arm, armv7a and x86). No MIPS support though.
In this post I'll describe the steps needed to get a GStreamer-1.0 SDK for Android MIPS.

Integration with Amazon SNS for push notifications

Pseudocode for Android integration with Amazon SNS:

server call to register for push notifications with registration token and DeviceId
if DeviceId is already stored then
    call DeleteEndpoint
else
    call CreatePlatformEndpoint to create new ARN for this device 
    store new ARN, Token and DeviceId
endif

I know there are other algorithms for working with Amazon’s SNS (like this one) but this seems to be the simplest, and it also solves the problem with Amazon not disabling the ARNs when applications are re-installed.
This should work for iOS-SNS integration, but I haven't had the chance to test.

Using the BPG image format on Android

There's a new image format in town and it's called BPG (Better Portable Graphics). Well, it's not so new, as it's been introduced in 2014, but it's new enough that you can find little information about integration with different platforms.
For academic/experimental purposes I've made a small Android application to see the format in practice.

Creating TextView and ToggleButton list on Android

There are lots of tutorials out there on creating lists with multiple elements, but none seem to work out of the box, with listeners and all.
So this is my way of implementing a list where each row consists of a TextView and a ToggleButton.

The code was tested on Android Studio and is intended for SDK 4.4+ (because everything that is below 4.4 should disappear, in my opinion).

Installing Android Studio on Ubuntu 14.04 LTS, Trusty Tahr 64 bit
