I found a related post. I have a simple app that displays a button on screen. I use Mac OS, latest android studio, and Java 8. I can launch android without the app, but get Android: Timed out after 300seconds waiting for emulator to come online
error with the app. The simulator setting is 1 GB RAM, 512 VM heap, Nexus 5X, marshmallow (android 23). How can I identify the problem and get app to run without reinstall everything?
From console:
/Users/me/Library/Android/sdk/tools/emulator -netdelay none -netspeed full -avd Nexus_5X_API_23
Hax is enabled
Hax ram_size 0x40000000
HAX is working and emulator runs in fast virt mode.
console on port 5554, ADB on port 5555
From app console:
06/10 19:25:48: Launching app
Error while waiting for device: Timed out after 300seconds waiting for emulator to come online.
