Android Studio error: Consider deleting _JAVA_OPTIONS

I am working on Kali Linux and wanted to get started with Android development and Flutter but I am getting this error after installing Android Studio:

The use of Java options environment variables detected. Such variables override IDE configuration files (*.vmoptions) and may cause performance and stability issues. Please consider deleting these variables: _JAVA_OPTIONS.

What does this mean and what can I do about it?

Solution

  • This warning comes up because you have an environment variable called _JAVA_OPTIONS setup by default. On Kali Linux, this variable typically carries default formatting/encoding for your Java installation.

    • To view the value of this variable, use printenv _JAVA_OPTIONS.
    • To delete the value of this variable, use unset _JAVA_OPTIONS.

    Once removed from your environment variables, Android Studio will no longer display the previous warning.

    [Edit]: I noticed that after deleting the variable, Android Studio was now able to build projects that were previously failing to build.

    NB: If you foresee a need for the variable elsewhere, you can copy it out and move it into your ~/.bashrc or ~/.profile (comment it with #) for later use.
