Not able to load image when captured from Camera second time

Question

I have been using Camera Intent to capture images. For the first time it works perfectly and I am able to capture image and show that in ImageView. But when I try second time to capture a different image it still shows the same old image.

Here is my code for Camera Intent and onActivityResult()

       Uri selectedImage;
        private Uri imageUri;


         private void activeTakePhoto() {

                            Intent intent = new Intent("android.media.action.IMAGE_CAPTURE");
                            File photo = new File(Environment.getExternalStorageDirectory(),  "Pic.jpg");
                            intent.putExtra(MediaStore.EXTRA_OUTPUT,
                                    Uri.fromFile(photo));
                            imageUri = Uri.fromFile(photo);
                            startActivityForResult(intent,REQUEST_IMAGE_CAPTURE);
                        }


      @Override
        protected void onActivityResult(int requestCode, int resultCode, Intent data) {
            super.onActivityResult(requestCode, resultCode, data);
            switch (requestCode) {
                case RESULT_LOAD_IMAGE:
                    if (requestCode == RESULT_LOAD_IMAGE && resultCode == RESULT_OK & null != data) {
                        selectedImage = data.getData();
                        imageView.setImageURI(selectedImage);
                    }

                    break;

                case REQUEST_IMAGE_CAPTURE:
                    if (requestCode == REQUEST_IMAGE_CAPTURE && resultCode == RESULT_OK) {
                        try {
                            selectedImage = imageUri;
                            getContentResolver().notifyChange(selectedImage, null);
                            imageView.setImageURI(imageUri);
                        } catch (Exception e) {
                            Toast.makeText(this, "Failed to load", Toast.LENGTH_SHORT)
                                    .show();
                            Log.e("Camera", e.toString());
                        }
                        Log.e("A", "AAA");
                    }
            }
        }


   submit.setOnClickListener(new View.OnClickListener() { // back to Activity A listView
            @Override
            public void onClick(View v) {
                Intent returnIntent = new Intent();
                amount = Amount.getText().toString();
                description = Description.getText().toString();
                type = spinnerType.getSelectedItem().toString();
                returnIntent.putExtra("type", type);
                returnIntent.putExtra("description", description);
                returnIntent.putExtra("amount", amount);
                if(selectedImage!=null) {
                    returnIntent.putExtra("img_uri", selectedImage.toString());
                }
                setResult(Activity.RESULT_OK, returnIntent);
                finish();
            }
        });

Activity A

 listview.setOnItemClickListener(new AdapterView.OnItemClickListener() { // if listView is clicked
            @Override
            public void onItemClick(AdapterView<?> a, View v, int position, long id) { // if list is clicked
                mClickedPosition = position;
                Object o = listview.getItemAtPosition(position);
                ImageAndText image = (ImageAndText) o;
                String type = image.getType();
                String amount = image.getAmount();
                String description = image.getDescription();
                Uri photo = image.getImage();
                String[] type1 = type.split(":");
                String[] amount1 = amount.split(":");
                String[] description1 = description.split(":");
                Intent i = new Intent(getApplication(), AddMoreClaims.class);
                i.putExtra("type", type1[1].toString().trim());
                i.putExtra("amount", amount1[1].toString().trim());
                i.putExtra("description", description1[1].toString().trim());
                i.putExtra("photo", photo);
                startActivityForResult(i, PROJECT_REQUEST_CODE);
            }
        });

Edited(add TimeStamp)

 private void activeTakePhoto() {
        String filename = "Pic_" + System.currentTimeMillis() + ".jpg";
        Intent intent = new Intent("android.media.action.IMAGE_CAPTURE");
        File photo = new File(Environment.getExternalStorageDirectory(),  "Pic.jpg");
        intent.putExtra(MediaStore.EXTRA_OUTPUT,
                Uri.fromFile(photo,filename));
        imageUri = Uri.fromFile(photo,filename);
        startActivityForResult(intent, REQUEST_IMAGE_CAPTURE);
    }

Answer 1

If we take a look at the source for ImageView, the setImageURI() method starts out with an if check similar to:

public void setImageURI(@Nullable Uri uri) {
    if (mResource != 0 ||
            (mUri != uri &&
             (uri == null || mUri == null || !uri.equals(mUri)))) {

        // Drawable resolution and update code
    }
}

As you can see from !uri.equals(mUri), the ImageView won't refresh itself if the Uri passed into the method equals() that already set. Your code is saving to the same file each time, so the Uris are always going to be the same.

Simply call imageView.setImageURI(null); before calling imageView.setImageURI(imageUri);. Alternatively, you could save to a different file each time; for example, by adding a timestamp to the filename.
