[android-developers] Phone's camera facing given gps coordinates
Hi, all can anyone give me an idea about how to wirte a android app to define whether my phone's camera is facing a given gps coordinates or not. and if not, give the direction to let my phone's camera to face that given gps coordinates. thanks alots Fu -- You received this message because you are subscribed to the Google Groups Android Developers group.

You need: + Given GPS point + Phone location (see docs) + Device orientation (see docs) + Linear algebra to determine angle of rotation difference between device orientation and target point (see high school) - TreKing http://sites.google.com/site/rezmobileapps/treking - Chicago transit tracking app for Android-powered devices -- You received this message because you are subscribed to the Google Groups Android Developers group.

Re: [android-developers] Phone's camera facing given gps coordinates
Well, technically, you need spherical trigonometry, not linear algebra. For nearby points, linear algebra will be a good approximation, so perhaps that's a good enough answer for him. But if you want an app to face you toward Mecca, for example, that won't be enough. A good navigation text will be helpful in that case. -- You received this message because you are subscribed to the Google Groups Android Developers group.
