I am trying to build a gallery app.I have fetched image path and date added from MediaStore.Images.
I have used the following code:
public static ArrayList<String> getAllShownImagesPath(Activity activity) {
Uri uri;
Cursor cursor;
int column_index_data, column_index_folder_name;
int column_index_date;
ArrayList<String> listOfAllImages = new ArrayList<String>();
String absolutePathOfImage = null;
long dateofimage;
uri = android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI;
String[] projection = { MediaColumns.DATA,MediaColumns.DATE_ADDED,
MediaStore.Images.Media.BUCKET_DISPLAY_NAME };
cursor = activity.getContentResolver().query(uri, projection, null,
null, null);
column_index_data = cursor.getColumnIndexOrThrow(MediaColumns.DATA);
column_index_date=cursor.getColumnIndex(MediaColumns.DATE_ADDED);
column_index_folder_name = cursor
.getColumnIndexOrThrow(MediaStore.Images.Media.BUCKET_DISPLAY_NAME);
while (cursor.moveToNext()) {
absolutePathOfImage = cursor.getString(column_index_data);
System.out.println("Imagepath-->"+absolutePathOfImage);
dateofimage = cursor.getLong(column_index_date);
System.out.println("date--->"+dateofimage);
Date d = new Date(dateofimage);
java.text.DateFormat formatter = new SimpleDateFormat("MMMM dd, yyyy h:mmaa");
String dateString = formatter.format(d);
//String dateString= convertDate(dateofimage,"dd/MM/yyyy hh:mm:ss");
System.out.println("date in format--->"+dateString);
listOfAllImages.add(absolutePathOfImage);
}
return listOfAllImages;
}
Please see the logcat I have posted below.The image path is coming perfectly,so as the time in milliseconds.But when I try to convert that millisecond into Date format,then I always get:January 17, 1970

I have also tried another method to convert millis in date,but ended up getting the same result:
public static String convertDate(long dateInMilliseconds,String dateFormat) {
return DateFormat.format(dateFormat, dateInMilliseconds).toString();
}
The number you are getting from your cursor is in the format of Unix Time which counts the number of seconds elapsed since 1 January 1970. For your date creation you want value in milliseconds. The easy solution is to multiply your result by 1000 and you are good to go.
