I am searching for a method to take a picture with the Camera of my phone without showing the User a Preview.
I know, that this is designed not to work, because its a security issue, but I am developing a "Get My Phone Back" app, that should be able to identify the thief, that has stolen my phone (in future^^). So it has to be stealth.
My phone is rooted, so I think there should be a way to do this. Any suggestions?
