I want to use my Android App as a “Producing client” for Kafka. After adding following dependecies:
// https://mvnrepository.com/artifact/org.apache.flink/flink-java
compile group: 'org.apache.flink', name: 'flink-java', version: '1.1.3'
// https://mvnrepository.com/artifact/org.apache.flink/flink-streaming-java_2.10
compile group: 'org.apache.flink', name: 'flink-streaming-java_2.10', version: '1.1.3'
// https://mvnrepository.com/artifact/org.apache.flink/flink-clients_2.10
compile group: 'org.apache.flink', name: 'flink-clients_2.10', version: '1.1.3'
// https://mvnrepository.com/artifact/org.apache.flink/flink-connector-kafka-0.8_2.10
compile group: 'org.apache.flink', name: 'flink-connector-kafka-0.8_2.10', version: '1.1.3'
I get this error message:
What went wrong: Execution failed for task ':app:transformResourcesWithMergeJavaResForDebug'.
com.android.build.api.transform.TransformException: com.android.builder.packaging.DuplicateFileException: Duplicate files copied in APK reference.conf File1: /home/lidox/.gradle/caches/modules-2/files-2.1/com.typesafe.akka/akka-remote_2.10/2.3.7/d5603ae49eefde410f5e75f41b4f60bee61b7bfd/akka-remote_2.10-2.3.7.jar File2: /home/lidox/.gradle/caches/modules-2/files-2.1/com.typesafe.akka/akka-actor_2.10/2.3.7/b20f18109689918f05238deea29e681946d30ef7/akka-actor_2.10-2.3.7.jar

I try to exclude one of the JARs, but no success:
packagingOptions {
exclude 'META-INF/**'
exclude 'META-INF/license.txt'
exclude 'META-INF/LICENSE'
exclude 'META-INF/notice.txt'
exclude 'META-INF/NOTICE'

}
Update 1:

Alternativly one could try to build an APK using maven, maybe it will work. The pom could be a combination of this and the pom building Android Applications with Maven
