I tried to search for the basic skills required for starting to learn android application development and many suggested that you need to be familiar with Java , c++ , pearl or php script , xml along with knowledge about usage of graphic resources.
My problem is I know nothing about above languages except for c++ which I've been learning for 2 years in my school.
Now what I want to know is, should I go ahead with learning android application development or is it waste of time to start without learning the other languages mentioned above ?
