I have updated Android Studio to version 3 and now seems unable to compile my project previously compiled without errors.
The error message is the follow
Error:Error: commons-logging defines classes that conflict with
classes now provided by Android. Solutions include finding newer
versions or alternative libraries that don't have the same problem
(for example, for httpclient use HttpUrlConnection or okhttp instead),
or repackaging the library using something like jarjar.
[DuplicatePlatformClasses]
The dependencies are
dependencies {
compile fileTree(include: ['*.jar'], dir: 'libs')
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:27.0.0'
compile 'com.android.support:design:27.0.0'
compile 'com.google.api-client:google-api-client-android:1.23.0' exclude module: 'httpclient'
compile 'com.google.http-client:google-http-client-gson:1.23.0' exclude module: 'httpclient'
compile 'com.google.firebase:firebase-core:11.4.2'
}
and error seems caused by
compile 'com.google.api-client:google-api-client-android:1.23.0' exclude module: 'httpclient'
compile 'com.google.http-client:google-http-client-gson:1.23.0' exclude module: 'httpclient'
I already use exclude module: 'httpclient'
So why It doesn't compile?
Is this a bug of Android Studio 3 and\or included com.android.tools.build:gradle:3.0.0 plugin or I'm missing something? With the previous version no problem to compile exactly the same project.
Add to build.gradle located in app module
configurations {
all {
exclude module: 'httpclient'
}
}
If the problem is with commons-logging then it must be excluded too.
Add the following code in app/build.gradle
configurations {
all {
exclude module: 'httpclient'
exclude module: 'commons-logging'
}
}
Got the same issue. I have done below changes
configurations {
all{
exclude group: 'commons-logging', module: 'commons-logging'
exclude group: 'org.apache.httpcomponents'
}
}
packagingOptions {
exclude 'META-INF/LICENSE.txt'
exclude 'META-INF/LICENSE'
exclude 'META-INF/NOTICE.txt'
exclude 'META-INF/NOTICE'
exclude 'org/apache/http/version.properties'
exclude 'org/apache/http/client/version.properties'
}
You should replace "compile" with "implementation" as it's deprecated in the latest gradle and exlude "org.apache.httpcomponents" from Google api client libraries:
implementation('com.google.api-client:google-api-client-android:1.23.0') {
exclude group: 'org.apache.httpcomponents'
}
implementation('com.google.http-client:google-http-client-gson:1.23.0') {
exclude group: 'org.apache.httpcomponents'
}
this solution was found here:
https://developers.google.com/google-apps/activity/v1/quickstart/android
Run in terminal, inside project folder:
./gradlew app:dependencies > dependencies.txt
Then check dependencies.txt to find who is using conflictive dependencies and act accordingly (check for updates, get rid of it, or use exclude as suggested by #Silverstorm)
If you want to continue with async-http then add below following code only in app/build.gradle
configurations {
all {
exclude module: 'commons-logging'
}
}
As 'org.apache.httpcomponents:httpclient:4.3.3' is deprecated after SDKversion 23 so
replace this:
compile 'org.jbundle.util.osgi.wrapped:org.jbundle.util.osgi.wrapped.org.apache.http.client:4.1.2'
with
compile 'org.apache.httpcomponents:httpclient:4.3.3'
I received these two errors today.
1. commons-logging defines classes that conflict with classes now provided by Android. Solutions include finding newer versions or alternative libraries that don't have the same problem (for example, for httpclient use HttpUrlConnection or okhttp instead), or repackaging the library using something like jarjar.

After struggling for sometime, I figured that I was using a Firebase library which was causing these errors.
implementation platform('com.google.firebase:firebase-bom:29.2.0')
So, I updated it:
implementation platform('com.google.firebase:firebase-bom:29.2.1')
And Invalidated Caches and Restarted the project and it worked like a charm.
Earlier BOM version of Firebase was also working fine.
implementation platform('com.google.firebase:firebase-bom:29.1.0')
Please don't update Firebase BOM version: 29.2.0
I removed commons-logging as suggested above, of course it crashed on some phone with Fatal Exception: java.lang.NoClassDefFoundError: Failed resolution of: Lorg/apache/commons/logging/LogFactory;. How can Android claim the commons-logging is conflicting with Android API when the Android API doesn't contain any of those classes?!? There is no org.apache.commons.logging at https://developer.android.com/reference/packages :facepalm:
I've added back implementation 'commons-logging:commons-logging:1.0.4' to the build.gradle - Android Studio underlines it with red but gradle compiles happily. :facepalm:
Android :triple_facepalm:
if you are facing this issue because of org.apache.httpcomponents:httpmime dependency, then use this in your app level build.gradle file:
implementation('org.apache.httpcomponents:httpmime:4.5.12') {
exclude group: 'org.apache.httpcomponents', module: 'httpclient'
}
implementation "org.apache.httpcomponents:httpcore:4.4.13"
I had to join multiple solutions from here. This is what worked for me:
configurations {
all*.exclude group: 'com.google.guava', module: 'listenablefuture'
configureEach {
exclude module: 'httpclient'
exclude module: 'commons-logging'
exclude group: 'commons-logging', module: 'commons-logging'
exclude group: 'org.apache.httpcomponents'
}
}
Add this then sync your gradle
configurations {
all*.exclude group: 'com.google.guava', module: 'listenablefuture'
all*.exclude module: 'httpclient'
all*.exclude module: 'commons-logging'
}
in my case android studio couldn't recognize "httpclient"
so i couldn't use #Silverstorm answer.
instead found another answer:
Error: json defines classes that conflict with classes now provided by Android
which implies to add below could in app build.gradle:
configurations {
all {
exclude group: 'org.json', module: 'json'
}
}
Why "import com.google.api.client.googleapis.extensions not found" is my case? I'm using android studio, android sdk 1.7.
I'm also add dependencies :
compile 'com.google.android.gms:play-services:9.4.0'
compile 'com.google.api-client:google-api-client:1.19.0' exclude module: 'httpclient'
compile 'com.google.http-client:google-http-client-gson:1.19.0' exclude module: 'httpclient'
Thanks alot!
You need add "-android", eg:
compile 'com.google.api-client:google-api-client-android:1.22.0'
(eg: the -android flavor)
https://github.com/google/google-api-java-client-samples/blob/master/tasks-android-sample/build.gradle has an example.
I'm trying to use Simple Framework in my project. Here is the dependency in XML format.
<dependency>
<groupId>org.simpleframework</groupId>
<artifactId>simple-xml</artifactId>
<version>2.7.1</version>
</dependency>
I've tried converting the dependency to Gradle acceptable format.
compile 'simpleframework:simple-xml:2.7.1'
But, I don't think it's correct. What is the correct gradle dependecy?
The correct Gradle dependency is:
compile 'org.simpleframework:simple-xml:2.7.1'
For Android, you also have to exclude dependencies as they are already in the Android SDK
compile ('org.simpleframework:simple-xml:2.7.1') {
exclude module: 'stax-api'
exclude module: 'stax'
exclude module: 'xpp3'
}
I'm new to android studio and am trying to import a project from eclipse but I feel like i am running into every single problem possible. The error I'm currently getting is:
Error:Execution failed for task ':jobFlexwithInvoice:packageAllDebugClassesForMultiDex'.
> java.util.zip.ZipException: duplicate entry: android/support/v4/view/MotionEventCompatEclair.class
Ive seen similar answers to problems like here and here. But i think I need more help because its just not going away. I've added the exception to just about everything in my build.gradle file, including the actual support 4v dependency just for kicks, and am still getting this error. And also I have multiple build.gradle files because of included projects? It seems like the project build.gradle file can be ignored, I just have to add the exceptions to the module build.gradle files? (which is annoying when someone says to add something to the build.gradle file, im not always sure which one)
Anyway, here are the dependencies sections of each of my build.gradle files as they currently are:
myApp:
dependencies {
compile ('com.android.support:multidex:1.0.0'){
exclude module: 'support-v4'
}
compile project(':facebook') {
exclude module: 'support-v4'
}
compile project(':apptentive')
compile project(':androidsdkui'){
exclude module: 'support-v4'
}
compile ('com.google.android.gms:play-services:+'){
exclude module: 'support-v4'
}
compile files('libs/android-support-v13.jar') {
exclude module: 'support-v4'
}
compile files('libs/DynamicPDF.jar')
compile files('libs/picasso-2.5.0.jar')
compile ('com.android.support:support-v4:22.0.0'){
exclude module: 'support-v4'
}
}
facebook:
dependencies {
compile files('libs/bolts-android-1.2.1.jar')
compile ('com.android.support:support-v4:22.0.0'){
exclude module: 'support-v4'
}
}
androidsdkui:
dependencies {
compile files('libs/appboy.jar')
compile ('com.android.support:support-v4:22.0.0'){
exclude module: 'support-v4'
}
}
there is also an apptentive build.gradle file but it does not have any dependencies. Before adding all of these exceptions I was getting the same error as the one in the first link, now the only difference is its android/support/v4/view/MotionEventCompatEclair.class instead of android/support/v4/util/TimeUtils.class
If there is a way to see where the duplicates are coming from that would be great too, I was unable to find anything with a quick google search.
I updated the question so you can see some of the ways I was doing things wrong. Some of my projects included support v4 and I wasn't excluding them right. The proper way to exclude things from projects is:
compile (project(':facebook')) {
exclude module: 'support-v4'
}
you have to put the extra set of parenthesis around everything after compile. Im assuming the same goes for excluding things from files
ie.
compile file(myfile.jar)
would become
compile (file(myfile.jar)) {
exclude module: 'support-v4'
}
Could you try adding the following in the top-level build.gradle file inside allprojects element? It should look something like below.
allprojects {
configurations {
all*.exclude group: 'com.android.support', module: 'support-v4'
}
}
Hope this helps.
I have an old eclipse based project , and i converted it to android studio based. The convertion success, but i have problem when adding other dependency, first i get error java.exe finished with non-zero exit value 2, because of duplicate dependency support v4, and i try to exlude modul support v4, but now im getting java.lang.NoClassDefFoundError: android.support.v7.app.AppCompatDelegateImplV14
this is my build.gradle:
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile project(':SlidingMenu')
compile project(':PhotoView')
compile project(':viewpager')
compile project(':StackBlur')
compile project(':FacebookSDK')
compile files('libs/LibAllShareInterface_2.0.0.jar')
// Exclude module support-v4 to remove duplicate
compile ('com.android.support:appcompat-v7:22.2.0') { exclude module: 'support-v4' }
compile('com.android.support:design:22.2.0') { exclude module: 'support-v4' }
compile('com.squareup.picasso:picasso:2.5.2') { exclude module: 'support-v4' }
compile('com.android.support:recyclerview-v7:21.0.0') { exclude module: 'support-v4' }
compile('com.android.support:cardview-v7:22.2.0') { exclude module: 'support-v4' }
compile('com.android.support:support-annotations:22.2.0') { exclude module: 'support-v4' }
}
Any help will be appreciated
Well although I am not gradle expert and I'm experiencing some problems myself, I was able to reproduce an error complaining about appcompat-v4, using your dependencies.
It seems that you are completely excluding support-v4 from all your dependencies, and since support-v4 is required, you must either specify it as a dependency separately, or change this:
compile ('com.android.support:appcompat-v7:22.2.0') { exclude module: 'support-v4' }
to this:
compile ('com.android.support:appcompat-v7:22.2.0')
so you don't exclude support-v4 completely from your project.
I did the second and the project could build (A sample project with just those dependencies defined).
