Android Error in Eclipse: “Unable to execute dex:

Question

I am trying an Android project using OpenSAML using Eclipse. I have added all the required jar files in the build path. Now, when I run the program as an Android Application the following error shows up:

[2012-11-18 11:52:59 - Dex Loader] Unable to execute dex: Cannot merge new index 67075 into a non-jumbo instruction!
[2012-11-18 11:52:59 - MyTestProgram] Conversion to Dalvik format failed: Unable to execute dex: Cannot merge new index 67075 into a non-jumbo instruction!

I googled a bit, but nothing came up. What could this error mean?

Answer 1

If using gradle build, just add the dexOptions into build.gradle to enable jumbo mode:

android {
    dexOptions {
        jumboMode = true
    }
}

Remember to run "gradle clean" before your new building.
