My Java app on Mac OS needs to process a file that is 2 gigabytes in size.

I already increased the maximum Heap size of Android Studio to 7000MB, by setting

-Xmx7000m

in the file studio.vmoptions, located in

/Users/[userName]/Library/Application Support/Google/AndroidStudio2024.2

But during the program execution, only 4.2GB are being used by the java process, and

java.lang.OutOfMemoryError: Java heap space

error occurs.

How can this be fixed?

• java
• android-studio
• out-of-memory

• 1 Are you sure you need to load the entire file into program memory all at once? What type of file is it? – VGR Commented yesterday

You can change the app's heap space by changing the launch configuration. You can add in the VM options the -Xmx7000m.

The change you did before in the studio.vmoptions is for the IDE itself.
