Unable to merge dex Android studio 3.0

Question

I have some problem with my project. In Android studio 2.3.3 it works fine but when I updated to 3.0 I have problem to marge dex.

I clean and rebuild project.

What is wrong:

Execution failed for task ':app:transformDexArchiveWithExternalLibsDexMergerForDebug'. com.android.builder.dexing.DexArchiveMergerException: Unable to merge dex

StackTrace:

org.gradle.api.tasks.TaskExecutionException: Execution failed for task ':app:transformDexArchiveWithExternalLibsDexMergerForDebug'.

yes. I'm trying to run app in Android Studio 2.3.3 and it works. So it is problem only when im using 3.0 version — qubuss, Nov 11 '17 at 22:22
Just a guess, but I think it's related to duplication of dependencies. because this problem occurs a lot since everybody is updating to Android Studio 3.0. e.g. [here](https://stackoverflow.com/questions/47086275/trying-to-build-android-project-with-glide-package-throws-unable-to-merge-dex). My guess was if you turn off the multidex lib, you might see a better stack trace, showing the duplication error. — Peppermint Paddy, Nov 11 '17 at 23:01

This is related to duplicated dependencies in your project. There is a duplicate dependency which is happened because some libraries is implicitly dependent to the same library but with different version. Gradle 4.1 which is used in the Android Studio is not forgiving for library duplication.

You can check it from dependencies tree with the following command in your terminal in Linux (app is your module name):

./gradlew app:dependencies

or if you're using Windows try this in command prompt:

gradlew.bat app:dependencies

Then after you found it, you need to exclude it from the library and use only one of them. Something like this:

compile('com.library.name:version') {
  // this is a case for duplicate support library version.
  exclude group: 'com.android.support'
  exclude module: 'appcompat-v7'
}

Be noted that you are better to use the same version of compileSdkVersion, buildToolsVersion, targetSdkVersion, and Support Library.

In my case it was related to dependency issue with gson given by awsgateway sdk and the gson already present.

gradle -q app:dependencies

Didn't show any differences in the dependencies, but the gradle build stack trace showed it was something related to gson. Caused by: com.android.dex.DexException: Multiple dex files define Lcom/google/gson/FieldNamingStrategy;

Following this issue, I added below config to build.gradle but that didn't fix the issue.

compile("com.google.code.gson:gson:2.3") {
    exclude module: 'gson:2.2.4'
}

I had to manually remove the jar(gson-2.2.4.jar given by apigateway during sdk generation) present in the app/libs folder.

i face the same problem then i found the solution from Here (Github)

Add

multiDexEnabled true

in Your Default Configuration exemple

defaultConfig {
    applicationId "my application id "
    minSdkVersion 14
    targetSdkVersion 27
    versionCode 1
    versionName '1.0'
    multiDexEnabled true
}

then Add

implementation('commons-validator:commons-validator:1.4.1') {
    exclude group: 'commons-collections', module: 'commons-collections'
}

in your dependencies. It's work for me i hope it's also slution your problem :)

Why you think that the OPs question and your problem (or that of the LeakCanary list) are "the same"? And why do you suggest adding `multiDexEnabled true` to the OPs default config, when it is already there? And finally, why do you suggest the OP adding a library without giving a reason to do so? – kalabalik Jan 10 '18 at 13:50
i suggest because i follow the answer but it doesn't work for me. i thoughts other people maybe face the same problem that's why i shear how do i solve this problem. – Akram Ibna Bashar Nihan Jan 10 '18 at 19:12
