Duplicate files during packaging of APK app-debug-unaligned.apk

Question

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

android {
compileSdkVersion 20
buildToolsVersion '20.0.0'
defaultConfig {
    applicationId 'com.app'
    minSdkVersion 9
    targetSdkVersion 20
    versionCode 1
    versionName '1.0'
}

    }
}
productFlavors {

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

dependencies {
compile fileTree(include: ['*.jar'], dir: 'libs')
compile 'com.android.support:support-v4:20.0.0'
compile 'com.android.support:appcompat-v7:20.0.0'

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'
}

Solution 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')

Solution 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.

I get same error again after put 2 maven link, pls help me how to fix this error. If put 1 maven link, it is okay. I will unaccept your question since I want many people tell me how to fix. Thank you.

[hoomi]

What are the two maven links that you put?

[hoomi]

The problem is that Android is already using apache httpclient. Is there a reason that u want to reimport it?

[Huy Tower]

I already update my solution in my question. I don't know why. You know?

[hoomi]

just remove the httpclient maven line and also remove the jar file. Unless you need a new function which is not available in the older versions you do need to reimport it

[Huy Tower]

No, I should use http-client, http-core ... and so the other *.jar files.

[hoomi]

Have a look at this developer.android.com/reference/org/apache/http/…. If you have all the classes that you need then you can stop importing them

[Huy Tower]

Ah, u see. I need use the other class had not had in Android SDK. ex. HTTPMuptile class ... u see, I want to upload multiple files ...

[hoomi]

I am not sure if you can override android libraries. Maybe you could find the source to the classes that you need and then import them directly

[IgorGanapolsky]

~"remove all the dependancy file from the system". How is that applicable to gradle builds?

[Nirmal Dhara]

no not using the gradle build. gradle download the duplicated jars in your system. we need to physically remove the folder of the jar file from your system, before you build the project again.

[user1767754]

You should clarify your answer again, its not easy to follow... thats why there are so many commant though

[Chris Ho]

sometime you need add exclude 'META-INF/DEPENDENCIES'

[Sadeq Shajary]

also you should add 'exclude 'META-INF/LICENSE.txt'' ' exclude 'META-INF/NOTICE.txt''

[Gaurav Sharma]

@SadeqShajary you actually don't.... Only the above mentioned files are sufficient to resolve this error
