This is related to a currently opened bug on Selendroid [Class resolved by unexpected DEX error · Issue #721 · selendroid/selendroid · GitHub](https://github.com/selendroid/selendroid/issues/721)

The issue is that the new version of Selendroid 0.11.0 and newer, uses the Gson library and probably your Android app does as I can see in your logcat log:

> W/dalvikvm(10203): **Class resolved by unexpected DEX** : Lcom/foo/modules/ApiModule;(0x42068960):0x58b33000 ref [Lcom/google/gson/GsonBuilder;] Lcom/google/gson/GsonBuilder;(0x42068960):0x57a62000  
> W/dalvikvm(10203): (Lcom/foo/modules/ApiModule; had used a different Lcom/google/gson/GsonBuilder; during pre-verification)

They are currently working on removing that dependency in order to get things working again.

A possible work around for now is to use older Selendroid versions 0.10.0 or older.
