why android emulator not working

Question

When I updated the Android Studio a few days ago, the Android Emulator stopped working. I tried to open a blank activity and the emulator did not work as well.

All the SDK tools have been installed and updated. Below are the event log and Logcat of a blank activity (Hello World!) when I run the blank activity.

Answer 1

I went to the Settings->Advanced in the Extented Controls in the emulator and then to Advanced and changed the OpenGL ES Render to SwiftShader and the OpenGL ES API level to Compatibility (OpenGL ES 1.1/2.0) and the errors appear to have gone away and the screen is now not displaying a white screen and is instead is displaying the google map, which is what the program is supposed to do. Does this seem like a good solution? Is there more I should do to not get screwed up in the future?
