everyone! I am quite new in developing android application. I am currently try to develop an android application like fingto improve my knowledge about an exam I have to take. I have a bit knowledge of Java, C and C++. In my app I want to scan a network and enumerate the nodes connected to. I need APIs to use network tools and a database. Do you can suggest me the right way to start? Which are the APIs I have to use to accomplish that and which permissions too? Thanks in advance.
