I recently installed Android Studio on my old Win7 system. It took about 2 hours to install. Everything opened properly, started to work and faced with the fact that neither the compiler nor the emulator would start. I can't say exactly what was holding me back, but the system told me to install Intel HAXM. My computer is old, 2003 year, I don't plan to upgrade yet (I need to learn first) I can't reinstall Windows either.
The purpose of the studio download: to create and run a simple Hello World application on mobile and build it up a little bit at a time. Is it possible to do this without tambourines or do I have to upgrade my computer to the level of a Chinese "supercomputer"? Maybe I should not install Android Studio yet, but install something simpler?
For now, I want to understand how to do Hello World, practice with design (minimal) and work with sqlite databases.
