Select multiple images from android gallery and get it path

Question

I know that there is a lot of examples on the internet for it but no one of those does what I really want. I want to select multiple images with an intent and get it "url" like this code does with one. (I know that this code cannot select more than one, but I use this as example of what I'm trying to do)

Code:

public static final int RESULT_LOAD_IMG = 0;
public void LoadImg() {
        Intent galleryIntent = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
        startActivityForResult(galleryIntent, RESULT_LOAD_IMG);
    }

ArrayList<Part> files = new ArrayList<>();

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);

        if (requestCode == RESULT_LOAD_IMG && resultCode == RESULT_OK && null != data) {
            Uri selectedImage = data.getData();
            String[] filePathColumn = {MediaStore.Images.Media.DATA};

            Cursor cursor = getContentResolver().query(selectedImage,
                    filePathColumn, null, null, null);
            cursor.moveToFirst();

            int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
            String picturePath = cursor.getString(columnIndex);
            files.add(new FilePart("uploadedfile[" + String.valueOf(files.size()) + "]", new File(picturePath)));
            cursor.close();
        }
    }

Searching on the internet I found this example from Laith Mihyar in this post: Select multiple images from android gallery and I want to do the same here, but the file path is different here and dont work for what I'm trying to do.

Code:

int PICK_IMAGE_MULTIPLE = 1
 String imageEncoded;    
 List<String> imagesEncodedList;
Intent intent = new Intent();
  intent.setType("image/*");
 intent.putExtra(Intent.EXTRA_ALLOW_MULTIPLE, true);
 intent.setAction(Intent.ACTION_GET_CONTENT);
  startActivityForResult(Intent.createChooser(intent,"Select Picture"), PICK_IMAGE_MULTIPLE);
@Override
        protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        try {
            // When an Image is picked
            if (requestCode == PICK_IMAGE_MULTIPLE && resultCode == RESULT_OK
                    && null != data) {
                // Get the Image from data

                String[] filePathColumn = { MediaStore.Images.Media.DATA };
                imagesEncodedList = new ArrayList<String>();
                if(data.getData()!=null){

                    Uri mImageUri=data.getData();

                    // Get the cursor
                    Cursor cursor = getContentResolver().query(mImageUri,
                            filePathColumn, null, null, null);
                    // Move to first row
                    cursor.moveToFirst();

                    int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
                    imageEncoded  = cursor.getString(columnIndex);
                    cursor.close();

                }else {
                    if (data.getClipData() != null) {
                        ClipData mClipData = data.getClipData();
                        ArrayList<Uri> mArrayUri = new ArrayList<Uri>();
                        for (int i = 0; i < mClipData.getItemCount(); i++) {

                            ClipData.Item item = mClipData.getItemAt(i);
                            Uri uri = item.getUri();
                            mArrayUri.add(uri);
                            // Get the cursor
                            Cursor cursor = getContentResolver().query(uri, filePathColumn, null, null, null);
                            // Move to first row
                            cursor.moveToFirst();

                            int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
                            imageEncoded  = cursor.getString(columnIndex);
                            imagesEncodedList.add(imageEncoded);
                            cursor.close();

                        }
                        Log.v("LOG_TAG", "Selected Images" + mArrayUri.size());
                    }
                }
            } else {
                Toast.makeText(this, "You haven't picked Image",
                        Toast.LENGTH_LONG).show();
            }
        } catch (Exception e) {
            Toast.makeText(this, "Something went wrong", Toast.LENGTH_LONG)
                    .show();
        }

        super.onActivityResult(requestCode, resultCode, data);
    }

Thanks

There is no "file path". ACTION_GET_CONTENT does not have to return a file Uri, and most of the time on newer devices it will return a content Uri.

Use ContentResolver and openInputStream() to get an InputStream on the content identified by the Uri. Use DocumentFile and fromSingleUri() to get at metadata about the content identified by the Uri.

I can't even load it in an ImageView

Picasso and other image-loading libraries (even Ion) work with content Uri values without an issue.

I'm trying to upload those files with the Ion lib, that needs a path

The best solution would be to use a better HTTP client library, one that offers greater flexibility. OkHttp (with Okio) should be able to handle uploading from a Uri.

Or, use ContentResolver and openInputStream() to get an InputStream on the content. Use FileOutputStream to get a stream on some local file (e.g., in getCacheDir()). Use Java I/O to copy the bytes from the InputStream to the FileOutputStream. Then, use the local file with Ion.
