Error :: duplicate files during packaging of APK

Android Studio. I'm getting this kind of error during application run.

Error:Execution failed for task ':app:packageDebug'. Duplicate files copied in APK META-INF/notice.txt

build.gradle

apply plugin: 'android'

android {
    compileSdkVersion 19
    buildToolsVersion "19.0.1"

    packagingOptions {
        exclude 'META-INF/DEPENDENCIES'
        exclude 'META-INF/NOTICE'
        exclude 'META-INF/LICENSE'
        exclude 'META-INF/LICENSE.txt'
        exclude 'META-INF/NOTICE.txt'
        exclude 'META-INF/ASL2.0'
    }

    defaultConfig {
        minSdkVersion 7
        targetSdkVersion 19
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            runProguard false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
        }
    }
}

dependencies {
    compile 'com.android.support:appcompat-v7:19.0.1'
    compile 'com.j256.ormlite:ormlite-android:4.48'
    compile 'org.codehaus.jackson:jackson-core-asl:1.9.13'
    compile 'org.codehaus.jackson:jackson-mapper-asl:1.9.13'
    compile 'com.octo.android.robospice:robospice:1.4.11'
    compile 'com.octo.android.robospice:robospice-spring-android:1.4.11'
}

How can I fix this error?

EDITED

These exclude options solved my problem:

packagingOptions {
        exclude 'META-INF/DEPENDENCIES'
        exclude 'META-INF/LICENSE'
        exclude 'META-INF/LICENSE.txt'
        exclude 'META-INF/license.txt'
        exclude 'META-INF/NOTICE'
        exclude 'META-INF/NOTICE.txt'
        exclude 'META-INF/notice.txt'
        exclude 'META-INF/ASL2.0'
    }

I think the string comparison is case sensitive. try with exclude 'META-INF/notice.txt'

I think you need to include only these options in build.gradle:

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

Short Answer:

See the detailed gradle output using gradle assemble and note the files that are duplicate and exclude them using:

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

Long Answer:

Run the assemble gradle task from command line for detailed output:

This automatically shows what to exclude:

	android {

See this part in output:

android {
  packagingOptions {
    exclude 'LICENSE'
  }
}

It even shows the list of dependencies which originated duplicate files (LICENSE). See the lines with Origin # in the output.

Add this in your build.gradle file ...

packagingOptions {
exclude 'META-INF/NOTICE' // will not include NOTICE file
exclude 'META-INF/LICENSE' // will not include LICENSE file
exclude 'META-INF/DEPENDENCIES' // will not include LICENSE file
exclude 'META-INF/LICENSE.txt'
exclude 'META-INF/NOTICE.txt'
}

like this...

android {
compileSdkVersion 25
buildToolsVersion "25.0.2"
defaultConfig {
    applicationId "your package name"
    minSdkVersion 14
    targetSdkVersion 25
    versionCode 30
    versionName "3.0"
    testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}
packagingOptions {
    exclude 'META-INF/NOTICE' // will not include NOTICE file
    exclude 'META-INF/LICENSE' // will not include LICENSE file
    exclude 'META-INF/DEPENDENCIES' // will not include LICENSE file
    exclude 'META-INF/LICENSE.txt'
    exclude 'META-INF/NOTICE.txt'
}
}

It's more than one error, you are right.

Under apply plugin: 'android-library'

add this ::

android {
    packagingOptions {
        exclude 'META-INF/ASL2.0'
        exclude 'META-INF/LICENSE'
        exclude 'META-INF/NOTICE'
    }
}

1st error is by file duplicates, 2nd is by LICENSE and NOTICE files. It will work after

EDIT:: See my post here about identifying the problems:: https://stackoverflow.com/questions/20673625/android-gradle-plugin-0-7-0-duplicate-files-during-packaging-of-apk/29996374#29996374

this works for me

android {
...

    packagingOptions {
        exclude 'META-INF/DEPENDENCIES'
        exclude 'META-INF/NOTICE'
        exclude 'META-INF/LICENSE'
        exclude 'META-INF/LICENSE.txt'
        exclude 'META-INF/NOTICE.txt'
        exclude 'META-INF/ASL2.0'
        exclude 'META-INF/notice.txt'
        exclude 'META-INF/license.txt'
    }
}

Interestingly, when I deleted this line from gradle, it worked:

compile 'org.apache.commons:commons-lang3:3.3.1'

I had to play around a bit to find the right location for the packagingOptions. Solving the duplicate file problem for a conflict between jackson-core:2.2.2 and jackson-databind:2.2.2 Also the DSL seems to have changed recently So in the recent Android Studio 1.4.1 with buildTools 23 you have to put android.packaging options on the same level as compileOptions AND NOT inside any model { android { braces !

model { 
   android {
        compileSdkVersion = 21
        buildToolsVersion = "23.0.1"
    
        defaultConfig.with {
              applicationId = "com.android.sensorgraph"
              minSdkVersion.apiLevel = 21
              targetSdkVersion.apiLevel = 22
        }
   }
    
   android.packagingOptions {
        exclude 'META-INF/LICENSE'
        exclude 'META-INF/NOTICE'
   }
   compileOptions.with {
        sourceCompatibility = JavaVersion.VERSION_1_7
        targetCompatibility = JavaVersion.VERSION_1_7
   }
}
