Date getDate is deprecated Java Android example code:
long dayInMili = 100000000;
GregorianCalendar calToDay = new GregorianCalendar();
int nD = calToDay.get((Calendar.MILLISECOND)); // +dayInMili;
System.out.println(nD);
long lTime = calToDay.getTimeInMillis();
System.out.println(lTime);
Date dtA = new Date(lTime); // today
///@SuppressWarnings("deprecation")
int nD1 = dtA.getDate(); // DEPRECATED Day Of Month 1 - 31
System.out.println(nD1+" nD1");
GregorianCalendar cal = new GregorianCalendar();
int nD2 = calToDay.get(Calendar.DATE); // Day Of Month
System.out.println(nD2+" nD2");
cal.setTimeInMillis(lTime+dayInMili);// setTime(dtA);
int nD3 = cal.get(Calendar.DATE); // Day Of Month + 1 day
System.out.println(nD3+" nD3");
Try each step separately:
- Restart Eclipse
- Clean project and rebuild
- Create a new project and try it if the problem persists, if no move copy project to other folder, delete project from workspace , create new project same name and copy java, xml etc. files to new project
- Close Eclipse, backup folder c:\Users\myName\workspace\.metadata and delete it. Restart Eclipse try again import project to workspace
- Re-installing the Android Developer Tools
- Re-installing Eclipse - rename old folder with Android to Android_old, create new folder C:\Program Files\Android and copy new Eclipse with sdk into new folder
- Created a new project importing from the file system
- Created a new project from subversion
