StatusNetAndroid Screen Cast

Some months ago I started with my “Praktikum” named StatusNetAndroid. Therefore I had to get familiarized with Android App development and the RESTful-APIs of twitter respectively twitter-like services (,, There are lots of tutorials and code snippets out there, but the tiny parts to glue them all together can cost you hours But [...]

Accessing twitter-like services via OAuth

After playing around with the twitter4j library to get it to work with my own network configuration (e.g. mentioned in an earlier post I ended up in searching for another solution, as twitter4j cost me already too much time.

After searching a while I found out [...]

Parsing XML resources on Android

As I already wrote in the previous post, I’m using the twitter4j library to connect to microblogging services like twitter. It’s shipped with a default configuration for the twitter network. The first tests, like sending and querying tweets, I performed while connected to the twitter network, which worked fine. Then I started to setup the [...]

Android TweetflowEditor Twitter-Login

We are currently working on an Android app that allows the creation of simple Tweetflows in a graphical editor. As our client should also be able to directly tweet the created Tweetflows without using other Twitter clients, one of our first tasks was to implement a login and tweet mechanism. Because some of our colleges [...]


As I’m doing my Projektpraktikum and the Bachelor thesis here at the DSG I’ll give you an introduction about the topic. In short, I’ll create an Android App which receives Tweets from a StatusNet server, which is an open-source Twitter server, and provides means to filter them regarding to a user defined pattern. The server [...]
