I get this error message:

I also get a message that says:

Hello,

These are two seperate problems.

For the HAXM problem, if you have an Intel CPU capable of HAXM acceleration, please make sure virtualization is enabled in your bios and then follow these instructions for Windows or these instructions for OSX. If you're running Linux, congratulations, it should just work with virtualization enabled.

If you have an AMD CPU, you should be able to get something running with Linux, not sure about Windows or OSX. If you do fall into this bucket, I'd recommend trying Genymotion. However, if you are going to try to use the default emulator in this case, make sure you're not running an x86 image and instead you're running an ARM image for your emulator.

For the ActionBarOverlayLayout issue, could you try prepending the string "Base." (note the dot there) before the rest of your AppTheme in your styles.xml file? You can use this stackoverflow post as reference.

If you need further assistance, please let me know and I will try to help further.
