setting image uri gives Unable to decode stream: java.io.FileNotFoundException:

Question

I've simple app for capturing image using Camera using following code

@AfterPermissionGranted(RC_STORAGE_PERMS)
private void launchCamera() {
    Log.d(TAG, "launchCamera");

    // Check that we have permission to read images from external storage.
    String perm = android.Manifest.permission.READ_EXTERNAL_STORAGE;
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M
            && !EasyPermissions.hasPermissions(this, perm)) {
        EasyPermissions.requestPermissions(this, getString(R.string.rationale_storage),
                RC_STORAGE_PERMS, perm);
        return;
    }

    // Create intent
    Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);

    // Choose file storage location
    File file = new File(Environment.getExternalStorageDirectory(), UUID.randomUUID().toString() + ".jpg");
    mFileUri = Uri.fromFile(file);
    takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, mFileUri);

    // Launch intent
    startActivityForResult(takePictureIntent, RC_TAKE_PICTURE);
}

now I want to upload that image to Firebase storage

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    Log.d(TAG, "onActivityResult:" + requestCode + ":" + resultCode + ":" + data);
    if (requestCode == RC_TAKE_PICTURE) {
        if (resultCode == RESULT_OK) {
            if (mFileUri != null) {
                uploadFromUri(mFileUri);
            } else {
                Log.w(TAG, "File URI is null");
            }
        } else {
            Toast.makeText(this, "Taking picture failed.", Toast.LENGTH_SHORT).show();
        }
    }
}

private void uploadFromUri(Uri fileUri) {
    Log.d(TAG, "uploadFromUri:src:" + fileUri.toString());

    // [START get_child_ref]
    // Get a reference to store file at photos/<FILENAME>.jpg
    final StorageReference photoRef = mStorageRef.child("photos")
            .child(fileUri.getLastPathSegment());
    // [END get_child_ref]

    // Upload file to Firebase Storage
    // [START_EXCLUDE]
    showProgressDialog();
    // [END_EXCLUDE]
    Log.d(TAG, "uploadFromUri:dst:" + photoRef.getPath());
    photoRef.putFile(fileUri)
            .addOnSuccessListener(this, new OnSuccessListener<UploadTask.TaskSnapshot>() {
                @Override
                public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
                    // Upload succeeded
                    Log.d(TAG, "uploadFromUri:onSuccess");

                    // Get the public download URL
                    mDownloadUrl = taskSnapshot.getMetadata().getDownloadUrl();
                    Log.w("IMAGE_URL", "Path is " + mDownloadUrl.toString());
                    uploadedImage = (ImageView) findViewById(R.id.uploaded_img);

                    try{// Here I'm setting image in ImageView                            
                        uploadedImage.setImageURI(mDownloadUrl);
                    }catch (Exception e){
                        System.out.print(e.getCause());
                    }

                    // [START_EXCLUDE]
                    hideProgressDialog();
                    ///updateUI(mAuth.getCurrentUser());
                    // [END_EXCLUDE]
                }
            })
            );
}

in uploadFromUri() at line

try{// Here I'm setting image in ImageView                            
    uploadedImage.setImageURI(mDownloadUrl);
}catch (Exception e){
    System.out.print(e.getCause());
}

image is not set in ImageView and I get error

and if I open this link I see image there, question is why it is not set in image view

setImageURI() is for content URIs particular to the Android platform, not URIs specifying Internet resources.

Try getting your bitmap from internet in a new thread an then add it to your ImageView. Like this:

uploadedImage.setImageBitmap(getImageBitmap(mDownloadUrl));


private Bitmap getImageBitmap(String url) {
        Bitmap bm = null;
        try {
            URL aURL = new URL(url);
            URLConnection conn = aURL.openConnection();
            conn.connect();
            InputStream is = conn.getInputStream();
            BufferedInputStream bis = new BufferedInputStream(is);
            bm = BitmapFactory.decodeStream(bis);
            bis.close();
            is.close();
       } catch (IOException e) {
           Log.e(TAG, "Error getting bitmap", e);
       }
       return bm;
    }

You also can use a useful library to set image (Internal and external images) called Picasso http://square.github.io/picasso/

Add Picasso library for image loading and use the following code.

Picasso.with(activity).load(imageURL)
    .resize(imageWidth,imageHeight)
    .into(imageView, new Callback() {
        @Override
        public void onSuccess() {
            Log.d(TAG,"successfully load the image");
        }

        @Override
        public void onError() {
            Log.d(TAG,"fail to load the image");
        }
});
