Dear mory4ok12,

you are getting this failure, because org/json/JSONArray.class is added to ProGuard from multiple inputs. To check which jars contains this class, open your build/moe/main/proguard/configuration.pro file and check the files specified as -injars for this class.
After finding the sources, remove/exclude them until only one remains. If the jar comes from a transitive Gradle dependency, you can exclude it in the buildscript.

Example:

compile('org.hibernate:hibernate:3.1') {
    exclude group: 'org.json'
}

Thank you. I do have such a line in configuration.pro
-injars ///.gradle/caches/modules-2/files-2.1/org.json/json/20160810/****/json-20160810.jar(!.framework/,!.bundle/)
But I can not figure out where it appears there . I check all my Gradle dependency. configuration.pro “Generating -injars” section are configured in what file ?

Dear mory4ok12,

you can use ./gradlew dependencies from the command-line to see the dependency tree.

Here is my dependencies tree. I exclude the duplicate dependencies, but still have the same problem
