Error - System Error while compiling Android classes.dex

Created a HelloWorld application and after spending 5+ hours trying to resolve this, thought I would try the forums. When I try to run the application in the Android Emulator, receive the message:

[INFO] Compiling Android Resources… This could take some time
[ERROR] System Error while compiling Android classes.dex
[INFO] Android Emulator has exited

Nothing is deployed to the emulator. Here are some details on how I have things setup:

Titanium SDK Directory: /home/user/.titanium/
Titanium SDK Version: 1.7.5
Android SDK Directory: /home/user/TitaniumStudio/sdk/android

Environment Variables:

export PATH=/usr/lib/jvm/java-6-sun-1.6.0.26/bin:/home/user/TitaniumStudio/sdk/android:$PATH
export JAVA_HOME=/usr/lib/jvm/java-6-sun-1.6.0.26
export android_sdk=/home/user/TitaniumStudio/sdk/android

It's probably really simple, just hoping for some advice on where to look for misconfigurations or suggestions on next steps for troubleshooting.

Thanks

  • If you start a new empty project (with the code the titanium generates) and run it as it is, do you still get this?

  • yes, actually the helloworld application is a new project with nothing added.

  • Resolved the problem. Located the file:
    /home/<myprobile>/.titanium/mobilesdk/linux/1.7.5/android/builder.py

    Changed the line …

    From:
    dex_args = [dx, '-JXmx1524M', '-JXX:-UseGCOverheadLimit']

    To:
    dex_args = [dx, '-JXmx1024M', '-JXX:-UseGCOverheadLimit']

    • So you changed 1524 to 1024. In my builder.py file the initial value is 1536. How did you think to make the change you did?

    • More of a lucky guess, walked through the logic in the script, unfortunately it just checks for the existence of classes.dex, if it doesn't exist after a particular operation, it just fails. The memory limit seemed high, thought I would try to tweak it and see what happens, and sure enough it worked.

  • WOW thank you so much. Searched for days to find an answer to this stacktrace. The problem is that I changed TitaniumStudio.ini to use 1024m instead of the default because my machine only has 3GB of memory. So another option is to change /home/me/Titanium_Studio/TitaniumStudio.ini to make sure it has the default memory settings (I think it was 1524m).
