问题
I've just download Eclipse + Android SDK, I was making the classic hello world and then change some stuff around the code, but every time I run the same project Eclipse launch a new emulator. How can I keep running the same app on the same emulator? It's boring waiting the emulator finish loading (it takes ages).
回答1:
Start emulator only once. After that you need not to close it after the first run. Your application will be installed automatically on the running emulator.
