Android Tidbits 6/8/2011: Warning! Warning!

Un-shadowed Method Warnings!

In response to yesterday’s question about Un-shadowed Method Warnings, Pivot Tyler points out that you can turn these on by calling Robolectric.logMissingInvokedShadowMethods(). Thanks!

Bad cached-robolectric-classes.jar

On two workstations every unit test was failing with the following error:

// …many levels of stack trace, finally:
Caused by: com.xtremelabs.robolectric.bytecode.IgnorableClassNotFoundException: msg because of javassist.NotFoundException: android.content.DialogInterface$OnShowListener
at com.xtremelabs.robolectric.bytecode.AndroidTranslator.onLoad(
at javassist.Loader.findClass(

Cause: there was an old tmp/cached-robolectric-classes.jar that was causing these errors and our tests ran successfully after deleting it. That’s two answers from Pivot Tyler!
