Android Question

file.exists() returns false for existing file in android

In my app user can select image from sdcard and set as profile picture. Everything is working fine but when user selects image from whatsapp folder from sdcard image can not decoded.

I am using following code to decode file and display in ImageView.

if (imgFile.exists()) {

Bitmap myBitmap = BitmapFactory.decodeFile(imgFile

myBitmap = null;


I am getting selected image path
/storage/sdcard0/WhatsApp/Media/WhatsApp Images/IMG-20130804-WA0000.jpg
and it exists in sdcard but
always returns false.
It works fine if user selects image from other folders rather than whatsapp.


I am following steps like

1. click on profilepic(imageview).
2. select options(from camera,galerry,or edit)
3. open selected or captured image in CropImage Activity.
4. display cropped image.

Anyhelp would be greatly appreciated..Thanks.


I was modifying image of other apps. I think this might be the problem. So what I did ?

  1. select image and get path in onActivityResult()
  2. copy image from this path in temp file using below code
  3. use temp file for cropping and other processing

private void copyFile(File sourceFile, File destFile) throws IOException {
    if (!sourceFile.exists()) {

    FileChannel source = null;
    FileChannel destination = null;
    source = new FileInputStream(sourceFile).getChannel();
    destination = new FileOutputStream(destFile).getChannel();
    if (destination != null && source != null) {
        destination.transferFrom(source, 0, source.size());
    if (source != null) {
    if (destination != null) {


Hope this may help someone else.
