Thanks for reporting this, I can confirm the bug. Just wanted to report it as well, and then found this issue. 👍

As described, the app only crashes when selecting multiple languages and does not start again until deleting all data. 😿

[FabulousOne]

Same happened to me...

[now0clock]

Still an issue. Same

[RedSteel-1]

The same :-/ Opened settings, chose some languages, and now impossible to launch, crashes on every attempt.

I have the loop open app-crash app still also when having multiple languages selected

[wincentbalin]

I confirm the crash as described above too. Also, this issue is a duplicate of the issue #40.

That works:

private String getLanguageNameFromCode(String code) {
    if (code.contains("+")) {
        String[] lang_codes = code.split("\\+");
        StringBuilder rLanguageName = new StringBuilder();
        for (String lang : lang_codes) {
            rLanguageName.append(languagesNames.get(languagesCodes.indexOf(lang)));
            rLanguageName.append("+");
        }
        return rLanguageName.subSequence(0, rLanguageName.toString().lastIndexOf('+')).toString();
    } else {
        return languagesNames.get(languagesCodes.indexOf(code));
    }
}
