Number formatting does not take into account locale settings. Consider using String.format instead. less… (Ctrl+F1)
\nWhen calling TextView#setText * Never call Number#toString() to format numbers; it will not handle fraction separators and locale-specific digits properly. Consider using String#format with proper format specifications (%d or %f) instead. * Do not pass a string literal (e.g. “Hello”) to display text. Hardcoded text can not be properly translated to other languages. Consider using Android resource strings instead. * Do not build messages by concatenating text chunks. Such messages can not be properly translated. Issue id: SetTextI18n More info: http:\/\/developer.android.com\/guide\/topics\/resources\/localization.html<\/p><\/blockquote>\n
