Coming back from parental leave, I suddenly found myself deeply involved in a new project called Eco-Friends. The goal is to make a demonstrator application for people to reflect upon their grocery shopping habits, and in particular products related to seasons. In our vision we will present a socially constructed framing of seasons or what …

Creating a button is similar to text except that it also uses a Listener callback function that is called as soon as the button is pressed. menuButton = (Button) findViewById(R.id.menubutton);menuButton.setOnClickListener(new OnClickListener() { //@Override public void onClick(View v) { // onClick Method //Do something when clicked }});
We now have a continuous readout from the magnetometer sensor. Next step is to play with magnets nearby the sensor to see how the values are changing. One thing we could do is to create a sort of distance measure. myAzimuth = Math.round(event.values[0]); myPitch = Math.round(event.values[1]); myRoll = Math.round(event.values[2]); abssum = Math.abs(myAzimuth) + Math.abs(myPitch) + …
So let us dig into the juicy bits! A google search on “android sensor orientation” turned up a promising result from ibm. At a glance it has some code that looks simple enough to explore. We wanna keep our package declaration and MainActivity class so we copy-paste from implements SensorListener { and onwards. With a …
This is sometimes easier than running on the AVD device (emulated devices tend to be slow and lack certain sensors). First one need to put the phone in developer mode and allow third party software through the phones settings. Then just plug in the USB cable and run the program and it should detect the …
A very fun and rewarding part of digging into a new environment is exploring and learning about its bits and pieces. Depending on ambition this can take many years, and since this is a workshop we will only touch upon a few of the fundamentals 😉 To the left we have the Workspace and Projects …
Create a new Android Project (File->New->Android Project). Give it a project name e.g. “helloandroid”, select a build target (I would recommend API level 4 and Android 1.6), name the application e.g. “Hello Android”, type in a package name e.g. “my.android.packages”, type in the Main Activity name e.g. “MainActivity” (The default entry point in our program …
In interaction design we often use various physical and digital materials that we recombine in novel and interesting ways. Today we also carry around mobile devices that have many of the sensors, actuators and networking capabilities that are commonly used in interaction design, e.g. touch, vibration, accelerometer, gyroscope, thermometers, NFC, GPS, etc. The goal for …
First of all we need to make sure that we have Java installed. If we want to develop with java we need the Java Development Kit (JDK) version. It can be downloaded from HERE. Next we need to get our Integrated Developing Environment (IDE) – Eclipse, where we do all the coding. Eclipse Classic can …
