Unable to execute dex: Java heap space Java heap space

Question

I am getting Unable to execute dex: Java heap space Java heap space error while executing web driver script in Eclipse IDE. I have configured Eclipse IDE with Android SDK and AVD Manager.

I also increased the -Xms200m to -Xmx512m but it did not work.

The accepted solution to this post worked for me: Conversion to Dalvik format failed: Unable to execute dex: Java heap space

The gist is: Keep increasing the Xms and Xmx values until it either works or you run out of physical memory.

E.g.: -XX:MaxPermSize=1536m -Dosgi.requiredJavaVersion=1.5 -Xms40m -Xmx1536m

You said

I also increased the -Xms200m to -Xmx512m

-Xms200m and -Xmx512m are two different things. Maybe you wanted to say

from -Xms200m to -Xms512m

and

from -Xmx200m to -Xmx512m

You can add these options in the file named **eclipse.ini** You can find more informations here http://wiki.eclipse.org/Eclipse.ini – Joand Jun 05 '12 at 15:56

Change -Dosgi.requiredJavaVersion=1.5 to

-Dosgi.requiredJavaVersion=1.6

if your eclipse project is using java compiler 1.6. I just solved this problem.

Adding this to my build.gradle finally solved it for me

dexOptions {
        preDexLibraries = false
}

When facing this problem I found that my eclipse.ini was renamed to _eclipse.ini, thus Eclipse was not able to find it and took to these misbehaviours.

I renamed it back to eclipse.ini and everything backed to work normally.
