Android Studio error on double with two non 0 decimals

Question

I have a problem on double with two non 0 decimals. For example, if my double is 15.00 it is ok, but if my double is 15.55 my app crashes. This is happening on my real phone (Galaxy s8+ - API 26), on all virtual devices from the android studio it works fine with all kinds of doubles (15.00 and 15.55). Can someone help with this?

My code:

DecimalFormat formatData = new DecimalFormat("#.##");    
Menu_ID.add(Long.parseLong(menu.getString("Menu_ID")));
Menu_name.add(menu.getString("Menu_name"));
Menu_price50.add(Double.valueOf(formatData.format(menu.getDouble("Price_50"))));

if(Category_ID == 1) {
    Menu_price100.add(Double.valueOf(formatData.format(menu.getDouble("Price_100"))));
}

Menu_image.add(menu.getString("Menu_image"));

Crash log

`my app crashes` with an exception and a stacktrace, which will show you the crash reason. Check it. (also post here) — Vladyslav Matviienko, Aug 09 '18 at 08:04

I do not know how to get my crash log from my phone. On android studio simulation (Virtual device works fine). — Iulian Nistor, Aug 09 '18 at 08:17
`do not know how to get my crash log from my phone` there are many ways. You just need to search for more than 10 seconds to find one. — Vladyslav Matviienko, Aug 09 '18 at 08:53
the problem is that `,` decimal separator. Try replacing all comas in that string to dots before parsing number — Vladyslav Matviienko, Aug 09 '18 at 09:48
**You think** that you don't have, but the stacktrace says that you do have. — Vladyslav Matviienko, Aug 09 '18 at 10:10
