Endless loading for emulator on low-end netbook I'm trying to develop on my old netbook but the emulator never completely loads. It keeps working and sometimes it freezes but then it doesn't finish booting.

I'm not really skilled in Android development and I would like to know if I can tweak the emulator to require less computational power. I'm learning new stuff so I don't have to run big stuff, I just need to start the emulator and launch a simple application
I would say the simple answer is no.  The emulator performs fairly poorly on high-end computers, so even if you got it to start up the performance would be beyond horrible.
