Date getDate is deprecated Java Android
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");

Old code with HashMap
Lint warning:
Use new SparseArray(...) instead for better performance
Issue: Looks for opportunities to replace HashMaps with the more efficient SparseArray
Id: UseSparseArrays
New code with SparseArray
SparseArray methods:
//developer.android.com/reference/android/util/SparseArray.html
Map<Integer, Bitmap> _bitmapCache = new HashMap<Integer, Bitmap>();
private void fillBitmapCache() {
_bitmapCache.put(R.drawable.icon, BitmapFactory.decodeResource(getResources(), R.drawable.icon));
_bitmapCache.put(R.drawable.abstrakt, BitmapFactory.decodeResource(getResources(), R.drawable.abstrakt));

_bitmapCache.put(R.drawable.scissors, BitmapFactory.decodeResource(getResources(),
}
Bitmap bm = _bitmapCache.get(R.drawable.icon);
