Ok, so i learned java basics ( Inheritance, loops, conditions ..etc ) and i also looked a little at android basics. When i'm searching through documentation on android site and checking various classes i see myself very familiar with java. But the real problem is:Let's say i want to build some notepad similar application or maybe SMS similar application. How do i know which classes to use? I know how to use them in code but i don't know which to use. With a little of searching i found that for example if i want to make recording voice application i should use MediaRecorder class. But can you give me some advice how are you people doing this? Which classes to use in certain application, just push me in right direction.. =)Thank you very much and appreciate your help in any way.
