Hello,
for one of my apps i need to create a list of months for which data is
available. I do this by polling the first date for which data is
available and then use a loop to increment the date until i reach the
present.
The code looks roughly like this:
Date startDate = new Date(firstAvailableDate);
if(DebugFlags.LOG_HELPERS)
Log.v("Creating MonthObjects - Startdate - " +
startDate.toGMTString());
GregorianCalendar today = new GregorianCalendar();
GregorianCalendar xCal = new GregorianCalendar();
xCal.setTime(startDate);
xCal.set(GregorianCalendar.DAY_OF_MONTH, resetDay);
while(xCal.before(today))
{
// Create new Object to save Data in
MonthObject xObj = new MonthObject();
xObj.setTimestamp(xCal.getTimeInMillis());
xObj.setFromDate(xCal.getTime());
// Add 1 Month to xCal
xCal.add(GregorianCalendar.MONTH, 1);
// Set Day to Day on which Statistics should reset
xCal.set(GregorianCalendar.DAY_OF_MONTH, resetDay);
// Make sure it's Midnight
xCal.set(Calendar.HOUR_OF_DAY, 0);
xCal.set(Calendar.MINUTE, 0);
xCal.set(Calendar.SECOND, 0);
xCal.set(Calendar.MILLISECOND, 0);
// Save it in Object
xObj.setToDate(xCal.getTime());
xObj.setToTimestamp(xCal.getTimeInMillis());
if(DebugFlags.LOG_HELPERS)
Log.v("Added MonthObject - " +
xObj.fromDate.toGMTString() + "
to " + xObj.toDate.toGMTString());
// Add to Collection
dates.add(xObj);
xObj = null;
}
xCal = null;
today = null;
return dates;
This works fine in 99% of cases; however, on at least one HTC Desire
with Android 2.1 this leads to an infinite loop and the log looks like
this:

This is repeated until the app crashes. Also, GregorianCalendar seems
to ignore all attempts to change the date when used in another context
(also only on this one mobile).
Does anyone have a clue why this happens or what I'm doing wrong?
Thank you!
Andreas
