What Computer Language Do I Need To Learn To Create Google Android Application?

Q. I only took 2 semesters of C++ and only retained the memory of creating that stupid "Hello World" program. I want to create my own Apps for Google's Android phones. Can you recommend what computer languages I should be learning (like Java) to make creating these apps easier?

A. I'm assuming that it will support Java, although being Linux it will run C++ if it is compiled for the phone. I would use Java though, because you won't need to cross compile.

Q. Not an emulator though. I would like to actually see Google Android and get a chance to use it. If not what about a recent and popular version of Linux? Thanks in advance for any help.
