Error: offset: 0, line: 239290, column: 1, 'void rx.observers.TestSubscriber.assertValue(java.lang.Object)' cannot be mapped to 'a' because it is in conflict with an existing member with the same signature. This usually happens when compiling a test application against a source application and having short generic names in the test application. Try giving 'a' a more specific name or add a keep rule to keep 'void rx.observers.TestSubscriber.assertValue(java.lang.Object)'.
