Could not launch emulator in Android Studio

Issue

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:

/home/next/NTE/MachineSetup/android-sdk-linux/tools/emulator -netdelay none -netspeed full -avd Nexus_5X_API_24 Could not launch '/home/next/NTE/MachineSetup/android-sdk-linux/tools/qemu/linux-x86/qemu-system-x86_64': No such file or directory

2. Error appear after gradle build completed:

12/02 16:47:57: Launching app Error while waiting for device: The emulator process for AVD Nexus_5X_API_24 was killed.

I have attached screenshots for your reference.

Solution

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.
