Answer 1

this is how i solved it:

• go to environment variables
• in system variables:
• New variable name: _JAVA_OPTIONS
• New variable value: -Xmx512M

Restart android studio

Answer 2

Perhaps this will help you.

→ → (Gradle - Android)

" VM" -Xmx512m -XX: MaxPermSize = 512

Answer 3

...

Invalid maximum heap size: -Xmx4g

The specified size exceeds the maximum displayed size.

Therefore, try to set javaMaxHeapSize to "1g" , because it depends on your maximum display size, which is set by your computer environment.

or

Just delete these lines

dexOptions {
incremental true
javaMaxHeapSize "4g"
}

Hope this helps you.
