Since Leapdroid is shut down so I make this FAQ if anyone need it. If you have a question, just comment in this page.
Q: What make Leapdroid outperform other emulators?
A: This emulator use much less CPU resource than other emulator
Deep explaination: While other emulators running with n + 1(1) core, Leapdroid only use n core so you will have big advantage on dual core CPUs compared to other emulators. Also their DirectX engine is fully implemented so you will not have extra CPU usage like other emulators.
(1): This extra core is used for screen rendering.
Q: What is Leapdroid default ADB URL?
A: localhost:5555. Leapdroid device name is emulator-5554
Q: I can't find Leapdroid on the internet anymore
A: Yes, the emulator is dead but you can grab my modded version here: http://max20091.blogspot.com/2016/11/leapdroid-1800-modded-by-max20091.html
More info: You can't use GPS anymore because Leapdroid have shut down their GPS server.
