When i start a new virtual device with genymotion sometimes it will get stuck on the black screen and not load. Sometimes it will work especially just after a restart, otherwise it will hang on the black screen and become unusable.
Reboot the PC (Windows) On Windows, a reboot is usually enough to fix the problem after Genymotion Desktop first run.
Genymotion also runs Robotium tests visibly faster, and with a smoother UI. However, be warned there are some noticable differences between Genymotion and the default Android emulators: You cannot use the special 10.0. 2.2 IP address with Genymotion to access localhost on the machine you are running the emulator from.
Press and HOLD the power button on Genymotion's UI on the bottom right. That will pop up the menu to restart. The app will freeze up as it shuts down, but upon rebooting it you will see that it has restarted.
It creates virtual devices (android phones). In short, VirtualBox takes some of your computer's memory and allocates that memory to a virtual device. It's all about the concept of virtualization. Without VirtualBox, you can't run Genymotion On macOS, windows, or Linux.
If the emulator freezes or crashes this is likely due to incompatability with your video card driver.
If however it just hangs on the black screen, this can be due to two reasons:
Your Firewall or other program is blocking genymotion
If this is likely the case then try disconnecting any vpn services or other software which could be hindering this, and ensuring that genymotion is able to connect to the virtual device over the local network.
If you have a firewall, make sure that you allowed connections to the Genymotion network, set to 192.168.56.0/24 by default.
Your network adaptor is misconfigured
If this is the case you should try the following
Run VirtualBox.
Open File > Preferences > Network (or VirtualBox > Preferences for Mac OS X).
Edit the Host-only Network by clicking .
Check that the adapter IPv4 address is in the same network (192.168.56.0/24 by default) as the DHCP server address, lower address bound and upper address bound. If not, your virtual device cannot start.
You can also remove the Host-only Network by clicking . Genymotion will automatically recreate it at the next virtual device start.
