Buat yang mo belajar Android ada tempat bagus nih untuk memulai.

App Inventor lets you develop applications for Android phones using a
web browser and either a connected phone or emulator. The App Inventor
servers store your work and help you keep track of your projects.
You build apps by working with:
The App Inventor Designer, where you select the components for your app.
The App Inventor Blocks Editor, where you assemble program blocks that
specify how the components should behave. You assemble programs
visually, fitting pieces together like pieces of a puzzle.
Your app appears on the phone step-by-step as you add pieces to it, so
you can test your work as you build. When you're done, you can package
your app and produce a stand-alone application to install.
If you don't have an Android phone, you can build your apps using the
Android emulator, software that runs on your computer and behaves just
like the phone.
The App Inventor development environment is supported for Mac OS X,
GNU/Linux, and Windows operating systems, and several popular Android
phone models. Applications created with App Inventor can be installed on
any Android phone. (See system requirements.)
Before you can use App Inventor, you need to set up your computer and
install the App Inventor Setup package on your computer.
