Duplicate files during packaging of APK app-debug-

问题:

I got this error Duplicate files during packaging of APK app-debug-unaligned.apk when put 2 jar files :

• httpclient-4.3.5.jar

• httpmime-4.3.5.jar

  into the libs folder after Sync with Gradle and Run.

If user 1 jar file - httpmime-4.3.5.jar, I will not get this error.

Please help me how to avoid this error & still can use 2 jar files in above also,

Thanks,

p/s : I use Android Studio version 0.8.6.

Error Detail

Error:duplicate files during packaging of APK ...\app\build\outputs\apk\app-debug-unaligned.apk Path in archive: META-INF/DEPENDENCIES Origin 1: ...\app\libs\httpclient-4.3.5.jar Origin 2: ...\app\libs\httpmime-4.3.5.jar

build.gradle

}

compile 'com.viewpagerindicator:library:2.4.1@aar'
compile 'de.hdodenhof:circleimageview:1.2.0'
compile files('libs/httpmime-4.3.5.jar')
}

UPDATE I changed from compile files('libs/httpmime-4.3.5.jar') to use Maven Link. I got same error again after put 2 maven link together:

    compile 'org.apache.httpcomponents:httpmime:4.4-alpha1'
compile 'org.apache.httpcomponents:httpcore:4.4-alpha1'

This is the warning

Warning:Dependency org.apache.httpcomponents:httpclient:4.4-alpha1 is ignored for debug as it may be conflicting with the internal version provided by Android. In case of problem, please repackage it with jarjar to change the class packages

Please help me fix.

SOULITION I know good answer now by addding these lines will fix Duplicate files error :

packagingOptions {
    exclude 'META-INF/DEPENDENCIES.txt'
    exclude 'META-INF/LICENSE.txt'
    exclude 'META-INF/NOTICE.txt'
    exclude 'META-INF/NOTICE'
    exclude 'META-INF/LICENSE'
    exclude 'META-INF/DEPENDENCIES'
    exclude 'META-INF/notice.txt'
    exclude 'META-INF/license.txt'
    exclude 'META-INF/dependencies.txt'
    exclude 'META-INF/LGPL2.1'
}

回答1:

You can replace compile files('libs/httpmime-4.3.5.jar') with this compile 'org.apache.httpcomponents:httpmime:4.3.5'.

Also you are duplicating the dependencies compile fileTree(include: ['*.jar'], dir: 'libs') already includes compile files('libs/httpmime-4.3.5.jar')

回答2:

update your build.gradle and add the following lines

android{
    .
    .
    .
    packagingOptions {
        exclude 'META-INF/license.txt'
        exclude 'META-INF/LICENSE'
        exclude 'META-INF/notice.txt'
        exclude 'META-INF/NOTICE'
    }
}

this will fix this error. I got the same error, doing this fixed it.

回答3:

Please update this to your build.gradle file.

    packagingOptions { 
     exclude 'META-INF/LICENSE.txt' 
     exclude 'META-INF/NOTICE.txt' 
 }

回答4:

I updated gradle now it's working

packagingOptions { exclude 'META-INF/DEPENDENCIES' exclude 'META-INF/LICENSE' exclude 'META-INF/LICENSE.txt' exclude 'META-INF/NOTICE.txt' }

回答5:

add the below code to dependencies

compile group: 'org.apache.httpcomponents' , name: 'httpclient-android' , version: '4.3.5' compile (group: 'org.apache.httpcomponents' , name: 'httpmime' , version: '4.3.5') { exclude module: 'org.apache.httpcomponents:httpclient' }

now if you run that it will show you why it is telling duplicate may be because of META-INF/NOTICE, META-INF/LICENSE, add that first again run it may show other type. add all like below under android section packagingOptions { exclude 'META-INF/LICENSE.txt' exclude 'META-INF/NOTICE' exclude 'META-INF/LICENSE' }

definitely it will solve your problem.

remove all the dependancy file from the system before build.
