Android Gradle duplicate files copied exception

Question

I have seen many versions of this question where the solution is to simply exclude the META-INF file name, but those are already excluded and the duplicate file, in this case, is not even a file associated with META-INF. When I run ./gradlew --stacktrace it compiles fine, but if I run the application on a device, the app crashes with the duplicate file warning.

apply plugin: 'com.android.application'

android {
compileSdkVersion 25
buildToolsVersion "24.0.3"
defaultConfig {
    applicationId "rocks.morrisontech.historicsf"
    minSdkVersion 19
    targetSdkVersion 25
    versionCode 1
    versionName "1.0"
    testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
    release {
        minifyEnabled true
        shrinkResources true
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}
packagingOptions {
    exclude 'META-INF/LICENSE'
    exclude 'META-INF/license.txt'
    exclude 'META-INF/license'
}

dependencies {

androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
    exclude group: 'com.android.support', module: 'support-annotations'
})

• Try: Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

I have noticed jersey is a dependency of com.socrata:soda-api-java:0.9.12, and when I delete that dependency I have no issues. I have also tried to use the soda-android-api, but that came with similar issues.

Answer 1

I just had the identical problem while trying to build a project using the soda-java library with Android Studio.

It looks like multiple copies of files are trying to be included into the APK. This is causing a problem and not allowing the APK to be built. We have to exclude these files in our app's build.gradle file under the android section as such.

packagingOptions {
    exclude 'META-INF/LICENSE'
    exclude 'com/sun/jersey/impl/api.properties'
    exclude 'com/sun/jersey/impl/spi.properties'
    exclude 'com/sun/jersey/impl/impl.properties'
    exclude 'META-INF/jersey-module-version'
}

Basically you will have to go through each one of these errors and add the below bolded file reported in the error.

com.android.builder.packaging.DuplicateFileException: Duplicate files copied in APK com/sun/jersey/impl/api.properties

Currently I am unsure if this is the proper long term solution. But it is letting me get up and running with writing my app. I will have to come up with a more long term and possibly appropriate solution down the road before release.
