I want to make a scope app for android that allows you use the rear camera for the android app as a scope, is this possible, I want to add lines to the app as well that will help aim. This is an app for a neft gun. Is this possible, if so can someone give me references/links or explanations on how to do this?
Use a SurfaceView to display the camera data, and then draw the scope into a transparent view on top of the surface view.
See the Preview example from android.com for an example on how to display camera data in a SurfaceView.

How to make a share button in my image application so that when we press share button it share the current image to different option like whats app,facebook etc.Plz Answer That
See the tutorial in the Android docs on Adding an Easy Share Action. It tells you exactly what you are asking.
That tutorial uses a ShareActionProvider, which is only since API 14. To support earlier versions of Android, take a look at the accepted answer in this thread. This third-party tutorial also provides lots of good info.
