Android Question Weird Error

[Descartex]

Hi!!
I've almost finished an app and, suddenly, it raised some weird errors on my app, such as:
1.- App closes when reaches this line:

DateTime.DateFormat="dd/MM/YYYY"

2.- App closes also when reaches this lines:

Variables.DataCheck.Put("Data",DateTime.Now)
Variables.DataCheck.Put("Sync",DateTime.Now)
'Being Variables.DataCheck a Map rightly initialized

In both cases it doesn't like the format:
First case, it raises "Unknown character pattern Y"
On second, it doesn't like the Caps of the map key...

I was using this for long time (from the beginning of the project), without problem.
I didn't made any change on my version before it started to fail...

Anyone has experimented any similar???

Best Regards.

First case, it raises "Unknown character pattern Y"

Y is WeekYear, y is Year

DateTime.DateFormat="dd/MM/YYYY"

Y must be lowercase:
https://docs.oracle.com/javase/7/docs/api/java/text/SimpleDateFormat.html

On second, it doesn't like the Caps of the map key...

Keys are case sensitive and you can use any combination of uppercase and lowercase letters (and not just alphabetic characters, of course)

But why it worked without any change???
I can't explain it...

Perhaps because it is not so (?)

And how to explain it works on 4 devices and fails on 3 others? Same code, same Java version, same IDE version... Compiled versions works on my devices and not on others...

Did you check android language setting for each device ? are they use same choice

That can be the problem... on those it fails, are configured on Portuguese, mine are Spanish...

Maybe, previously i'm facing same problem while date compare between server and device date, i thought it was Date & Time setting matter but it doesn't affect, until i know that using different Language setting is the cause (i don't know why), the working one using English (US) while the other English (Canada). So i set all device to English (US) and the issue has gone.

I suppose it should only be used temporarily, only to work on dates, otherwise, if I'm not mistaken, the language and currency would also change. So we would also need the "reverse" code, like resetting the default Local, the device setting.
