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

In case someone else was having this problem with the Project Tango examples provided via Github, I solved it by commenting the following line out in the app's build.gradle file for those projects which failed to run:

compile fileTree(dir: external_lib_prefix + '/jar', include: ['**/*.jar'])

Answer 2

In case you have:

compile 'com.android.support:recyclerview-v7:24.2.0'
compile('com.android.support:appcompat-v7:23.2.0') { exclude group: 'com.google.android', module: 'support-v4' }

in your project, add also:

compile 'com.android.support:support-v4:24.2.0'

or

compile 'com.android.support:design:24.2.0'

Answer 3

In my case the problem was in module sdk version. I changed it from 2.2 to 4.4 and the problem was solved.

Answer 4

Clean and rebuild was all it took for mine to start working.

Answer 5

I had same issue in Android Studio 2.3, in my case I had a mixture of version numbers which threw the build out, I changed:

dependencies {
    compile 'com.google.android.gms:play-services-wearable:7.5.0'
    compile 'com.google.android.gms:play-services-analytics:7.5.0'
    compile 'com.google.android.gms:play-services-drive:8.4.0'
}

to

dependencies {
    compile 'com.google.android.gms:play-services-wearable:8.4.0'
    compile 'com.google.android.gms:play-services-analytics:8.4.0'
    compile 'com.google.android.gms:play-services-drive:8.4.0'
}
