Very slow response of Android Emulator with Ionic app

Problem

Android emulator is very slow, sometimes have refresh problems and sometimes ion-select does not respond on clicks.

Solution

1. Launch up Android studio IDE
2. Choose menu item “Run” and then “Select Device”
3. Next click on “Open AVD Manager”
4. Find the Virtual device you are using and click the pencil (Edit) icon next to the device, on the AVD manager. This will launch device configuration.
5. Next Click on “Show Advanced Settings” at the bottom of the screen.
6. Scroll down to the “Memory and Storage” section and increase the memory to something optimal. In my case, I had a default of 16MB for VM heap size, which I increased to 256MB and it was blazing fast ever since!
