I am using native Android camera and save file to my application data folder (/mnt/sdcard/Android/data/com.company.app/files/Pictures/). At the same time anther copy of photo is saved to DCIM folder.
This is my code:
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
String formattedImageName = getDateString() + ".jpg";
File image_file = new File(this.getExternalFilesDir(Environment.DIRECTORY_PICTURES), formattedImageName);
Uri imageUri = Uri.fromFile(image_file);
intent.putExtra(MediaStore.EXTRA_OUTPUT,imageUri);
startActivityForResult(intent, REQUEST_FROM_CAMERA);
How can I prevent saving additional copy of image to DCIM folder?
Many Thanks
check this code..
private void FillPhotoList() {
// initialize the list!
GalleryList.clear();
String[] projection = { MediaStore.Images.ImageColumns.DISPLAY_NAME };
for(int i=0;i<projection.length;i++)
Log.i("InfoLog","projection "+projection[0].toString());
// intialize the Uri and the Cursor, and the current expected size.
Cursor c = null;
Uri u = MediaStore.Images.Media.EXTERNAL_CONTENT_URI;
Log.i("InfoLog","FillPhoto Uri u "+u.toString());
// Query the Uri to get the data path. Only if the Uri is valid.
if (u != null)
{
c = managedQuery(u, projection, null, null, null);
}
// If we found the cursor and found a record in it (we also have the id).
if ((c != null) && (c.moveToFirst()))
{
do
{
// Loop each and add to the list.
GalleryList.add(c.getString(0)); // adding all the images sotred in the mobile phone(Internal and SD card)
}
while (c.moveToNext());
}
Log.i(INFOLOG,"gallery size "+ GalleryList.size());
}
and this is where the method is doing all magic
/** Method will check all the photo is the gallery and delete last captured and move it to the required folder.
