I tried to find a list of all hardware sensors that the SonyEricsson Xperia X10 Mini has and could not find any information about it, so I delved down into the Android Javadoc and wrote a small program to list them all. I am posting the list here in case someone else might have use for it.
First comes the name/ID/model and then the maker:
AK8973 Orientation - Asahi Kasei Corp.
AK8973 Orientation Raw - Asahi Kasei Corp.
AK8973 Magnetic - Asahi Kasei Corp.
AK8973 Temperature - Asahi Kasei Corp.
BMA150 accelerometer - Bosch Sensortec GmbH
APDS9700 Proximity - SEMC
MSM Lightsensor - SEMC
The question is now what exactly can be done with them? For example, for what do I use the magnetic sensor? I downloaded a compass program but that seemed to only use the GPS.
