I’m a beginner on android. I’m learning using the video lessons of Professor Neri, but in his video lessons (android 2.2) did not use Ragments, but in my projects I’m creating he always creates with Ragment, so much so that the layout I draw in fragment_main, but I don’t know how to use this Ragment properly. Someone can point me to an article that explains this part of the use of Fragments, because several times I’m having problems with it causing my application to simply close.
Take a look at this question: http://answall.com/questions/17483/qual-a-diferen%C3%A7a-entre-desenhar-na-Activity-e-no-Fragment. In it I try to clarify some concepts and the use of
Fragmentplease use onlyActivitysand also the advantages and disadvantages of each. I think it can be useful for you.– Wakim
