Emulator's operation is unstable and I am in trouble in android studio2.3.1

cocos2dx3.15
emulator Nexus5 API22 Android5.1 CPU arm

NDK r10e

Sometimes the application starts up, it does not start, it is freezing on the main screen and it is in trouble.

When building with emulator, I want to know if you have stable environment settings.

Because it is an iPhone user, think of actual devices only for development😔
