FileNotFound exception while loading bitmap images from Android gallery

Question

I am trying to create a bitmap image from my Android gallery. I do this in an AsyncTask and this is the reason why I have a cursor in my implementation. The code is the following

                try {
                uri = Uri.parse(uriStr);
            } catch (Exception e) {
                Log.e(LOG_TAG, "problem with the image loading: " + e);
            }
                if(uri == null)
                    continue;
                Bitmap bm = null;
                try{
                    bm = MediaStore.Images.Media.getBitmap(activity.getContentResolver(), uri);
                } catch (FileNotFoundException e) {
                    Log.e(LOG_TAG, "Bitmap not found: " + e);
                } catch (IOException e) {
                    Log.e(LOG_TAG, "Bitmap IO error: " + e);

When I debug, I notice there is a FileNotFoundException thrown, the output:

08-17 13:47:55.754 30333-30668/com.example.jonas.shoppinglist W/System.err﹕ java.io.FileNotFoundException: No content provider: /storage/emulated/0/Download/unnamed.jpg 08-17 13:47:55.833 30333-30668/com.example.jonas.shoppinglist W/System.err﹕ at android.content.ContentResolver.openTypedAssetFileDescriptor(ContentResolver.java:1086) 08-17 13:47:55.921 30333-30668/com.example.jonas.shoppinglist W/System.err﹕ at android.content.ContentResolver.openAssetFileDescriptor(ContentResolver.java:941) 08-17 13:47:55.975 30333-30668/com.example.jonas.shoppinglist W/System.err﹕ at android.content.ContentResolver.openInputStream(ContentResolver.java:666) 08-17 13:47:56.019 30333-30668/com.example.jonas.shoppinglist W/System.err﹕ at android.provider.MediaStore$Images$Media.getBitmap(MediaStore.java:849) 08-17 13:47:56.062 30333-30668/com.example.jonas.shoppinglist W/System.err﹕ at com.example.jonas.shoppinglist.processes.ShoppingGallery.doInBackground(ShoppingGallery.java:51)

The result is that I didn't get one single bitmap image of my gallery. What is the problem?

Answer 1

you can try below code for achiving proper image path from gallery .....


public void pickImage() {
            Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
            intent.setType("image/*");
            startActivityForResult(intent, 1000);
        }

    @Override
        public void onActivityResult(int requestCode, int resultCode, Intent data) {
            super.onActivityResult(requestCode, resultCode, data);
            if (requestCode == 1000 && resultCode == Activity.RESULT_OK) {
                if (data == null) {
                    // Display an error
                    return;
                }

                if (Build.VERSION.SDK_INT < 11)
                    ImagePath = RealPathUtil.getRealPathFromURI_BelowAPI11(this,
                            data.getData());

                // SDK >= 11 && SDK < 19
                else if (Build.VERSION.SDK_INT < 19)
                    ImagePath = RealPathUtil.getRealPathFromURI_API11to18(this,
                            data.getData());

                // SDK > 19 (Android 4.4)
                else
                    ImagePath = RealPathUtil.getRealPathFromURI_API19(this,
                            data.getData());

            }
        }
