Usually, in Android, we read the accelerometer开发者_如何转开发 data in an \"Activity\", by overriding the OnSensorChanged function.
Need help to implement Accelerometer Sensor to an Image. How to move an image according to the device movi开发者_开发知识库ng(rotation)?
By no means I am a physics expert. I am writing an iOS (iPad to be precise) App which will present a door knob sign, hanging off a (surprise) door knob. What I need to accomplish is to simulate a pend
