Answer 1

As tech_android has already posted in this comment to solve this problem forever:

Remove dependency on an external JAVA installation using the built-in JDK.

Answer 2

This is a bug in older JDK versions. Go to the project structure and change your project to the latest JDK, for example, 1.80_72 or later.

Hope this fixes your issue.

Answer 3

1) Update the latest version of JDK, in my case jdk1.8.0_162

2) In Android Studio, select "File-> Project Structure → SDK Location → JDK Location, write the directory C: \ Program Files \ Java \ jdk1.8.0_162

3) Restart Android Studio

Solution

Answer 4

It solved my problem when I used the built-in version of the JDK (recommended)

Do this :

Project Structure → SDK Location → Select Use Integrated JDK (Recommended)
