I cannot get my emulator to run. Getting error messages.

Hey Jon!

I've put together a few fixes for you to try. Hopefully one of them will work! Please follow this in order so, try the first one before any of the later ones!

First of all, have you tried resetting the ADB system yet? If not, here's how to do it: Click on the Android Device Manager icon next to the SDK Manager in Android Studio (It is just an Android Icon). Then, wait for the manager to start up (It might start up behind Android Studio so, check your taskbar!). After that, click on the arrow on the Devices sidebar and then press Reset adb. Then, wait for the adb to reset and try again!:

If that doesn't fix your issue, try Invalidating Android Studio's caches. To do this, click on the File tab then Invalidate Caches / Restart and press Invalidate and Restart:

If that hasn't fixed the issue, make sure you have ticked Use Host GPU on your Emulator! To do this, open up the AVD Manager then click on the Edit pencil icon by your device. Then, on the edit screen, make sure you have Use Host GPU checked.

If that also didn't fix the problem, make sure you have not assigned too much RAM! This is known to cause problems with booting the emulator. Continue from the same screen as above but, this time, click Show Advanced Settings then scroll down to RAM. Make sure the value isn't too high here (But also not too low). It may also be worth checking the VM Heap as well - you don't want that too high (Or low) either!

I know there's a lot to take in here but, just try each option one at a time! Hopefully one will work for you! If not, let me know and I'll see if there's anything else that can be done :)
