listAreaDescriptions() crashes with UTF8 error about tango-examples-java HOT 2 CLOSED

Project "java_floor_plan_example" crashes when saving ADF with the following:

E/tango_client_api: TangoErrorType TangoService_saveAreaDescription(char (*)[37]): Internal Error: Could not save an area description. Is learning mode enabled?
A/art: art/runtime/check_jni.cc:64] JNI DETECTED ERROR IN APPLICATION: input is not valid Modified UTF-8: illegal start byte 0xb4
A/art: art/runtime/check_jni.cc:64]     string: ' ͏dp��d�'
A/art: art/runtime/check_jni.cc:64]     in call to NewStringUTF
A/art: art/runtime/check_jni.cc:64]     from int com.google.atap.tango.TangoJNINative.SaveAreaDescription(java.lang.String[])
A/art: art/runtime/check_jni.cc:64] "AsyncTask #1" prio=5 tid=19 Runnable

The project is unmodified so it has learning mode enabled, the correct load/save permissions etc.

First experienced this with my own project and been debugging this the whole day without much progress. Finally found out that the problem exists in the sample project as well so I'm posting this here.

It would seem that the encoding between Java and the C/C++ JNI of Tango lib is getting jumbled up. Check this: http://stackoverflow.com/questions/12127817/android-ics-4-0-ndk-newstringutf-is-crashing-down-the-app

I am completely lost as to how proceed..

Seems to be the error if permission for ADF File Load is not granted. So if permission is granted error does not occur.
