DexException: Cannot merge new index 65536 into a non-jumbo instruction

Question

For some unknown reason my app suddenly won't build from Android Studio.

I'm keep getting

> com.android.ide.common.internal.LoggedErrorException: Failed to run command:
    /home/martynas/android-sdk/build-tools/19.1.0/dx --dex --num-threads=4 --output
...
...
...
Error Code:
2
Output:
UNEXPECTED TOP-LEVEL EXCEPTION:
com.android.dex.DexException: Cannot merge new index 65536 into a non-jumbo instruction!

While the same application is built successfully from command line. I've checked method references count and it's way below the dreaded 64k.

I'm using AS 0.8.11 now.

Set the jumboMode property in build.gradle:

android {
    ...
    dexOptions {
        jumboMode true
    }

}

I also found this useful: Showing dex method count by package.

Thanks! It works for me too. But what does this "jumboMode" mean? – yital9 Oct 06 '16 at 11:06

@yital9 you can learn more about jumbo mode here: http://stackoverflow.com/a/30517283/4034572 – Albert Vila Calvo Apr 10 '17 at 08:46
please explain the reason for this block – eC Droid Aug 31 '17 at 11:09
I added this inside debug build type alone as the release build goes fine, because of proguard. The debug build went fine after this modification. Is this fine? – garnet Sep 23 '17 at 10:51
Where is this file build.gradle? Inside the platform directory? Since I am on Ionic project. But I don't want to mess with the platform directory, what else could be done? – Francisco Souza Mar 17 '18 at 13:57

This works for me. Note that the build.gradle to be changed should be the module that throws com.android.dex.DexException. – Francis Bacon Jul 16 '18 at 11:45

Try to add this line on your project.properties

dex.force.jumbo=true

Which increment the limit for strings in a dex files. And your project will probably compile.

Note : Also with jumbo set, the is another limit of 64K only for methods in an single dex. If you get this limit in the future , you will need to remove some dependencies.

Update - Google Play Services 6.5 (12-08-14)

With version 6.5 Google finally unbundled the Google Play Services. So from now on it'll be possible to selectively compile the APIs into your executable.

Example :

compile 'com.google.android.gms:play-services-maps:6.5.+'
compile 'com.google.android.gms:play-services-ads:6.5.+'

For all the other individual Google Play Services APIs check this page on d.android.com.

Adding to `project.properties` did not work so I updated my gradle build script as described here: http://stackoverflow.com/questions/17320088/android-build-dex-jumbo-mode-in-gradle – Martynas Jurkus Sep 29 '14 at 06:42

I did both solutions: adding dex.force.jumbo property and dexOptions but I'm still receiving the same error. Another option? – Juan Saravia Jan 30 '15 at 13:20
@juancho,Check : https://developer.android.com/google/play-services/setup.html#split – Haresh Chhelana Jan 30 '15 at 13:26
Thanks @HareshChhelana. For some reason it started to work.. but I really didn't do anything special. I have some coworkers who are compiling the project without this options, but now it's working for me. Thanks! – Juan Saravia Jan 30 '15 at 19:25

instead of compiling the entire Google Play Services, i found using the 'base' bundle to be useful, to stay below the 65K dex limit: `compile 'com.google.android.gms:play-services-base:7.3.0'` – kip2 Jul 24 '15 at 10:32
The "compile" configuration is now deprecated and should be replaced by "implementation" or "api" – A.A Nov 22 '18 at 12:40

This works for me. I was getting com.android.dex.DexIndexOverflowException: Cannot merge new index 66636 into a non-jumbo instruction!

android {
    ...
    dexOptions {
        jumboMode true
    }
}

If this isn't working, you might have reached method reference limit in dex which is a different issue. You need to use either multidex or proGuard.

This is a bug in the merger when the dex files that are being merged have more than 65536 strings. The new index can't fit in a const-string instruction, and the dex merger doesn't support changing instructions if they are different sizes, so it can't be widened to a const-string/jumbo instruction.This was fixed in jb-mr1 by adding a new option: --force-jumbo.This bug can be fixed by adding "dex.force.jumbo=true" to the project.properties.

@DeepakSharma You have to clean your project after enabling jumboMode – Lilo Sep 09 '15 at 08:07

With latest Android Studio and flag "force jumbo" checked on Android Studio compiler settings, this problem disappear.
