Question
We are starting android development for our mhealth platform and I was super thrilled to see this 29$ android at walmart, it has kitkat 4.4 Bluetooth 4.0 , and specs mention accelerometer, but will we be able to code our pedometer to work decently on this one?
Answer
Android 4.4 KitKat contains contains APIs which handle the more "difficult"/low level programming of a step counter for you (assuming the phone in question has that hardware). From what I have read about the Optimus 34C, it doesn't seem to come with that step counter hardware so you will indeed need to code it yourself.
I am currently working on an app for Android Wear in which I am using the accelerometer of the watch to trigger a method. Since I found that programming this accelerometer code wasn't too difficult and, in my experience, my watch's pedometer is rather accurate, I think you will probably be able to code a decent pedometer for your app on your own.
