Android Studio build error - Multiple dex files de

Question

I am unable to build my project in Android Studio. I get the following error:

Error:Android Dex: [RaditazAndroid] Unable to execute DX
Error:Android Dex: [RaditazAndroid] com.android.dx.util.DexException: Multiple dex files define Landroid/support/v4/accessibilityservice/AccessibilityServiceInfoCompat$AccessibilityServiceInfoVersionImpl;

However, this error means nothing to me. It does not provide clues as to where I should begin fixing my project. Has anybody encountered something similar?

Answer 1

I had the same error.

Removing a library(jtwitter.jar) form my-project/app/libs folder helped me.

Then cleaned the project and ran it and it worked.

Answer 2

For others wondering why this problem still persist even doing all other things suggested, This may help.

For me problem started when i added Glide library

dependencies {
  .........
  implementation 'com.github.bumptech.glide:glide:4.8.0'
  .........
}

and i had added already.

implementation 'com.android.support:design:26.1.0'

Which was contradicting with Glide support library somewhere.

Solution: Remove or downgrade your Glide support version.

 implementation 'com.github.bumptech.glide:glide:4.0.0'

Answer 3

Away from Android Studio, I opened the project in finder/workspace and did this:

1- MyProject folder -> build -> intermediate -> dex-cache -> cache.xml, and deleted all support-v4.jar items.

2- Also away from Android Studio, Went to every module in my project -> lib folder -> and deleted support-v4.jar as well.

Then cleaned the project and ran it and it worked thanks god :)

Answer 4

I had the same error.Solved it by adding to gradle file.

    dependencies{
        compile 'com.google.android.gms:play-services:8.3.0'
        compile 'com.android.support:appcompat-v7:23.1.0'
        compile 'com.android.support:support-v4:23.1.0'
    } 

Answer 5

For anyone who is interested, I solved my own problem. My mistake was that I had pasted android-support-v4.jar and google-play-services.jar in all of my project's module lib folders (my project consists of 3 modules). What I had to do instead was to paste these jars only into my main module's lib folder, and the other modules would automatically reference them.

Answer 6

I used a different approach by merging ABS res folder with my res folder and using ActionBarSherlock.jar as a global lib.

Works well so far and hope this help someone! But this is a hack since I was fed up of doing many things and I can't use Gradle since some of the other developers using Eclipse ADT without Gradle.

Root Cause for the issue is using android-support-v4 in ABS and my project both and it's complicating DEX.
