Unable to Merge Dex - Android Studio 3.0
Add an explicit dependency to play-services-auth
along with your firebase-ui-auth
dependency:
// FirebaseUI for Firebase Auth
compile 'com.firebaseui:firebase-ui-auth:3.1.0'
compile 'com.google.android.gms:play-services-auth:11.4.2'
This is because firebase-ui-auth
has a transitive dependency to play-services-auth
and must be used with the corresponding version of play-services-auth
. Please see this explanation.
firebase-ui-auth
|--- com.google.firebase:firebase-auth
|--- com.google.android.gms:play-services-auth
Earlier versions of the Gradle build tool did not include transitive dependencies so now versions can conflict with other play-services
versions.
My Issue Explained and Answered (In case anyone wants to know)
When you upgrade to Android Studio 3.0 and update the gradle build tool version to 3.0.0, compiling of dependencies is now done differently than in earlier versions.
I recently encountered the same issue. I was using these dependencies which worked fine through Gradle version 2.3.3:
implementation 'org.apache.httpcomponents:httpmime:4.3.6'
implementation 'org.apache.httpcomponents:httpclient-android:4.3.5.1'
After the upgrade to gradle-build-version 3.0.0, I got the same error. Digint into it, I found that the transitive dependency of httpmime
conflicted with the file httpclient-android
was including.
Description
Let me explain this in detail. Earlier, while using gradle-tool-version 2.3.3, I was using httpclient-android
to fetch and use the class named org.apache.http.entity.ContentType.java
Expanding the transitive dependencies of org.apache.httpcomponents:httpmime:4.3.6
showed that it has org.apache.httpcomponents:httpcore:4.3.6
which is the same package I wanted to use. But while compiling or syncing the build, it was excluding org.apache.http.entity.ContentType.java
so I needed to add this dependency which includes ContentType.java
:
implementation 'org.apache.httpcomponents:httpclient-android:4.3.5.1'
Everything worked fine after that.
Once I upgraded the gradle-build-version to 3.0.0, things changed. It now included all transitive dependencies. So while compiling with the latest Android Studio with gradle-build-tool version 3.0.0, my ContentType.java
was being compiled twice. Once from org.apache.httpcomponents:httpcore:4.3.6
(which is an implicit transitive dependency of httpmime
) and again from org.apache.httpcomponents:httpclient-android:4.3.5.1
which I was using earlier.
To resolve this issue I had to remove the existing org.apache.httpcomponents:httpclient-android:4.3.5.1
dependency as httpmime
would itself fetch the relevant class required for my application.
The solution for my situation: only use required dependencies and remove the httpclient-android
implementation 'org.apache.httpcomponents:httpmime:4.3.6'
Note that this is just the case for me. You'll need to dig into your own dependencies and apply the solution accordingly.
Unable to Merge Dex - Android Studio 3.0.1 DexArchiveMergerException
I have solved after try all the solutions on stackoverflow, try to do the following steps in its order
- Replace all compile with implementation
- Make all supportLibraryVersion = '27.0.2'
- Change
'com.google.android.gms:play-services-maps:11.8.0'
to
'com.google.android.gms:play-services-maps:11.4.0'
- Remove all the unused library
- Delete the .gradle folder inside your project
- Remove build folders and the gradle cache
- file -> invalidate caches/restart
- Build > Clean Project
- Add
dependencies { implementation 'com.android.support:multidex:1.0.1'}
- Add
android {
defaultConfig {
multiDexEnabled true
}
}
- Async project
And finally this is my App file
apply plugin: 'com.android.application'
android {
compileSdkVersion 27
defaultConfig {
applicationId "com.example"
minSdkVersion 18
targetSdkVersion 27
versionCode 1

release {
minifyEnabled false

}
}
}
ext {
supportLibraryVersion = '27.0.2'
}
dependencies {

}
ِِActually I didn't understand the real reason about it and why that happened suddenly
So if anyone know that please tell me with full details
I hope this will help you
Unable to Merge Dex after upgrading to Android Studio 3.0
Caused by: com.android.dex.DexException: Multiple dex files define Lcom/ogaclejapan/smarttablayout/utils/ViewPagerItems$Creator;
My guess is that you are not supposed to be using all three of these, but rather only one or two of them:
implementation 'com.ogaclejapan.smarttablayout:library:1.6.1@aar'
implementation 'com.ogaclejapan.smarttablayout:utils-v4:1.6.1@aar'
implementation 'com.ogaclejapan.smarttablayout:utils-v13:1.6.1@aar'
Android Studio: Execution failed for task: unable to merge dex
I executed this gradle, and it works only problem I can see here is implementation project(':openpayandroid')
, i didn't included it as its your private library, but on my understanding openpayandroid is also including some same dependencies which is causing the problem, so solution can be to exclude that group from it, eg implementation project(':openpayandroid')
{
exclude group 'the dex error causing lib group'
}
if above does'nt work try this
in your project build.gradle try use same version of all the groups e.g.
if (details.requested.group == 'com.android.support'
&& !details.requested.name.contains('multidex')) {
details.useVersion "26.1.0" // your version
}
I think this might help but if this doesn't work try to check which file is responsible for this dex error and edit your question
One more thing you have include permission helper twice, remove (but it might not be the problem )
Unable to merge Dex error: Android Studio 3.0
Ok, I managed to fix my problem! I had to add these two lines:
In app/gradle.build:
compile 'com.android.support:multidex:1.0.1'
In Manifest file:
android:name="android.support.multidex.MultiDexApplication"
I obtained this from this question:
Didn't find class "com.google.firebase.provider.FirebaseInitProvider"
Unable to merge dex Android - Studio 3.0 build error
Finally, I figured this out with below.
compile('com.jayway.jsonpath:json-path:2.0.0') {
exclude group: 'net.minidev', module: 'asm'
}
