POGson throws an exception on > 4.0 devices

Body
copied!<p>I'm using Gson successfully to place json into an object. It works like a charm on devices with android 2.2 (emulator and real device), when I deploy to android 4.0 and above (emulator and device) I get this very weird exception.</p> <p>I've confirmed that there is no problem with json string because the same code runs happily on older devices. </p> <p>The exception is definitely being thrown here:</p> <p><code>Gson gson = new GsonBuilder().setFieldNamingPolicy(FieldNamingPolicy.LOWER_CASE_WITH_UNDERSCORES).create(); return gson.fromJson(jsonString, t);</code> </p> <p>in the fromJson method.</p> <p>Any ideas? </p> <p>Json
