Runtime error PowerMock + Mockito: ProxyFrameworkImpl could not be located in classpath

问题:

I am trying to use PowerMock with the Android InstrumentTestCase Since my test runs on an Android device the libraries needs to be added to the apk.

I encounter big issues with powermock+mockito and Dex files. I have a runtime error with only powermock+mockito in my dependencies:

org.powermock.api.extension.proxyframework.ProxyFrameworkImpl could not be located in classpath. 

And a compilation error if I include either cglib/cglib-nodep (has suggested in answers):

com.android.dex.DexException: Multiple dex files define Lnet/sf/cglib/beans/BeanCopier$BeanCopierKey 

Here is a part of my gradle.build:

androidTestCompile 'com.android.support.test:runner:0.3' androidTestCompile 'org.powermock:powermock-api-mockito:1.6.4' androidTestCompile 'org.powermock:powermock-module-junit4:1.6.4' androidTestCompile 'cglib:cglib-nodep:3.2.0' androidTestCompile 'cglib:cglib:3.2.0' 

What am I missing ?

Thanks in advance!

I also tried to use PowerMock for Android instrumentation tests and got stuck with the same issue.

Here is what I've found on PowerMock github

PowerMock won't work on Android if you run it on a device since PowerMock is using JVM byte code manipulation. It will work if you run it on a JVM though.

So, I guess PowerMock is only appropriate for unit testing on Android.
