Ok, here's the thing. I'm working on developing an application for Android which is NOT entirely based on Processing. I'm following these tutorials and I've got to the part where a simple menu is made. First option in a menu is some simple adding/substracting of numbers, second is a some kind of text transformer, simple stuff, but I tried to go a step further and added a third option in a menu which leads to a Processing application. In short, I managed to add a Processing based app to a "normal" Android app using only eclipse (it has nothing to do with the android mode of Processing).

Everything is working fine for now, but I'd like to know more about adding/saving pictures. I know that, if I want to load an image, I have to put it in /assets folder and it works just fine, but I'd really like to know how to load an image from the phone's gallery and then save it to the same place. I really tried to find a solution online, but I really did not find anything that I can use so I'm asking for your help.

Thanks in advance!
