Android Resources$NotFoundException on a specific language

Issue

So basically, I have an app which has thousands of downloads and some users (around 200) see their app crashing on an activity with this exception android.content.res.Resources$NotFoundException: at android.content.res.Resources.getStringArray (Resources.java:1391)

So here is where the code crash (at the second line) :

int arrayId = getResources().getIdentifier(ct, "array", view.getContext().getPackageName());
String[] ctOp = getResources().getStringArray(arrayId);

The array I retrieve has this tools:ignore="MissingTranslation" and it is only in values folder (nothing in values-XX for example).

Another thing is that all people who contacted me about this crash come from Turkey.

Solution

I found the issue, I was doing this :

ct = ct.toLowerCase();

And apparently in Turkish there is a bug if you do it this way so you need to do it like that :

ct = ct.toLowerCase(Locale.ENGLISH);

Same for toUpperCase
