ofxAndroidMagneticField proposal [Do not Merge]

[pelayomendez]

First implementation of the MagneticField Sensor in Android. Needs testing and feedback from Android tablets and phones.

The compass uses accelerometer to improve sensor feedback trying to avoid 2.3 API and gyroscope / gravity hardware so maybe it´s not the most accurate way.

Magnetic field is implemented in a different JAVA class, not sure if it should share class with other Android sensors similar to iOS CoreLocation.

An example is included for testing.

Best,

P.

Hi, nice work.
I did an app some time ago using the magnetic field sensor in an android phone.
I just used wrote a wrapper for the sensors API, and worked really well. I actually wrote it for all the available sensors, as I had to test which one worked better.
I never pushed it to github because the code was quite dirty and I modified several core files. @arturoc should there be a particular way in which the sensors should be implemented?

You can take a look at what I did here:

You were allowed to draw just by moving the phone. I was really accurate considering that this thing wasn't intended for doing such thing.

Hi Roy,

Nice to hear that. I would be great if OF Android can take advantage of all the work you´ve already done on this. And I´m really curious about it. Please let me know if I can help in any way.

Best.

What is the current state of affairs?

Hi. Nothing from my side. Haven't looked at this in a long time. Right now I can't but I'll keep it in mind. I'll let you know about any progress.
