I am developing an android app where i am getting all the images from the gallery in a grid view and displaying it along with a checkbox..i m able to select the images and upload multiple images to the server....but now before uploading it to the server i need to rename the images i am selecting as per my conventions.....m not able to do that!! How do i go about that??? anybody has any idea?? Please help!! I really need to do this!! i am getting the paths of the selected images in an array list ...
public void btnChoosePhotosClick(View v){
selectedItems=new ArrayList<String>();
**selectedItems** = imageAdapter.getCheckedItems();
Toast.makeText(MultiPhotoSelectActivity.this, "Total photos selected: "+selectedItems.size(), Toast.LENGTH_SHORT).show();
Log.d(MultiPhotoSelectActivity.class.getSimpleName(), "Selected Items: " + selectedItems.toString());
}
and i am trying to change the name while uploading but i get file not found exception...
UploadToServer upload=new UploadToServer();
protected Void doInBackground(Void... params) {
// TODO Auto-generated method stub
String imagepath;
String imagename;
doctype_imagename="1234_doctype_pageno_"+System.currentTimeMillis()+".jpg";
for( int i=0;i<selectedItems.size();i++)
{
if (isCancelled()) {
break;
}
else
{ try
{
imagepath=selectedItems.get(i);
//upload.uploadFile(imagepath);
sourcefile=new File(imagepath);
imagename=imagepath.substring(imagepath.lastIndexOf("/")+1);
from=new File(Environment.getExternalStorageDirectory(),imagename);
to=new File(Environment.getExternalStorageDirectory(),doctype_imagename);
from.renameTo(to);
upload.uploadFile(to.getAbsolutePath());
}
