NoSuchMethodError when using WireMock in an Android integration test

Question

Got the following stack trace when trying to start a WireMockServer in my robotium android test. Might be a conflict between 2 versions of Apache Http client, but I did not

Answer 1

WireMock now works in an Android app as of January 2016. This is fixed as of a couple of weeks ago with WireMock 2.0.8-beta from the 2.0-beta branch. I've updated that WireMock GitHub issue and have created a sample project showing it working.

Here are the build.gradle dependencies you'll need to use it:

androidTestCompile("com.github.tomakehurst:wiremock:2.0.8-beta") {
    //Allows us to use the Android version of Apache httpclient
    exclude group: 'org.apache.httpcomponents', module: 'httpclient'

    //Resolves the Duplicate Class Exception
    //Error:Execution failed for task ':app:transformClassesWithJarMergingForDebugAndroidTest'.
    //       > com.android.build.api.transform.TransformException: java.util.zip.ZipException: duplicate entry: org/objectweb/asm/AnnotationVisitor.class
    exclude group: 'asm', module: 'asm'

    //Fixes conflict with Android's version
    //Warning:Dependency org.json:json:20090211 is ignored for debugAndroidTest as it may be conflicting with the internal version provided by Android.
    //In case of problem, please repackage with jarjar to change the class packages
    exclude group: 'org.json', module: 'json'
}
androidTestCompile 'org.apache.httpcomponents:httpclient-android:4.3.5+'
