Could not launch emulator in Android Studio

Question

I tried to launch application in emulator in android Studio in ubuntu 14.04 and it shows the following errors.

1. Error shown while gradle build is in process:

Answer 1

The first error's reason is below:

There are two emulators: one in $SDK/tools, another one in $SDK/emulator.
The one in $SDK/tools cannot start.

Please place $SDK/emulator before $SDK/tools in your $PATH variable, it should fix the problem.

Answer 2

Not sure if this will help for you but I was seeing this error trying to run emulator in the console. I changes the ANDROID_SDK to point to the bin folder in my .bash_profile and that corrected the issue

export ANDROID_HOME=~/Library/Android/sdk

export ANDROID_SDK=$ANDROID_HOME/lib

Answer 3

1: add $SDK/emulator in your $PATH variable
2: remove $SDK/tools in your $PATH variable
3: adb kill-server
4: adb start-server
5: Start the emulator from the command line

Example:
emulator @Pixel_XL_API_23
