i have to change the name of a jpg file , for that i have written the following code
sdcard = Environment.getExternalStorageDirectory();
from = new File(sdcard,imagePath.substring(8).toString());
to = new File(sdcard,"/DCIM/RoseVille_"+Info.getText()
+"_"+Amount.getText()+"_"+timeStampFormat.forma t(n ew Date())+".jpg");
/// if renamming is successfull;
this code creates a new file with the required name while the file which i wanted to change is still their on sd card , if i remount the sd card then the old file gets deleted and the renamed file remains their.
so my problem is how to rename the file without remounting the sd card
