I'm needing some help because I can't get the solution by my own, I had read a lot of post and investigating a lot but without solution.
I've a proyect that have some subprojects ( actionbar,sliding,facebook,etc.. ) and when I try to compile it I receive following error all times.
[2013-07-31 14:44:06 - Dex Loader] Unable to execute dex: Cannot merge new index 67109 into a non-jumbo instruction!
[2013-07-31 14:44:06 - ojiva] Conversion to Dalvik format failed: Unable to execute dex: Cannot merge new index 67109 into a non-jumbo instruction!
I'm using Eclipse with latest ADT and latest tools ( r22 ) with latest SDK ( 18 ). I've set dex.force.jumbo=true on my project.properties and also I've tried with set dex.force.jumbo=true
But without lucky :(, any ideas ?
Try adding dex.force.jumbo=true to your project.properties file
For intellij or Android studio users: Settings - Android Compiler - DEX, you can check the flag.
However you MUST rebuild your project, otherwise you will still see the same error.
With latest Android Studio and flag "force jumbo" checked on Android Studio compiler settings, this problem disappear.
Hope that help to someone.
