I run the app on my ASUS tablet with Android 4.2.1. The tablet is set to Hebrew. The app title appears correctly in Hebrew. When I run it, however, I see the English Wikipedia: if I search for Hebrew article titles, I don't find anything, and if I search for English titles, I find them.
This may be related to the famous iw/he confusion in the language codes. If this is indeed the case, then it may also affect Yiddish and Indonesian ( http://developer.android.com/reference/java/util/Locale.html )
The app version is Version 2.0alpha1.
Version: Unspecified
Severity: normal
