Camera multiple files upload not working RocketWeb Android

After buying from CodeCanyon I configure the app, everything was working fine but can’t upload multiple images.

Update this line of code will solve the issue:

if (checkPermission(PERMISSIONS_REQUEST_CAMERA, true) &&
        checkPermission(PERMISSIONS_REQUEST_WRITE_EXTERNAL_STORAGE, true)) {
    if (PreferenceUtils.getInstance().getBooleanValue(Constants.KEY_FILE_UPLOAD_ENABLE, true)) {
        if (mFilePath != null) {
            mFilePath!!.onReceiveValue(null)
        }
        mFilePath = filePathCallback
        var takePictureIntent: Intent? = null

        if (PreferenceUtils.getInstance().getBooleanValue(Constants.KEY_PHOTO_UPLOAD_ENABLE, true)) {
            takePictureIntent = Intent(MediaStore.ACTION_IMAGE_CAPTURE)
            if (takePictureIntent.resolveActivity(this@HomeActivity.packageManager) != null) {
                var photoFile: File? = null
                try {
                    photoFile = createImageFile()
                    takePictureIntent.putExtra("PhotoPath", mFileCamMessage)
                } catch (ex: IOException) {
                    Log.e(TAG, "Image file creation failed", ex)
                }

                if (photoFile != null) {
                    mFileCamMessage = "file:" + photoFile.absolutePath
                    takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(photoFile))
                } else {
                    takePictureIntent = null
                }
            }
        }

        val contentSelectionIntent = Intent(Intent.ACTION_GET_CONTENT)

        if (PreferenceUtils.getInstance().getBooleanValue(Constants.KEY_MULTIPLE_FILE_UPLOAD_ENABLE, false)) {

        }

            contentSelectionIntent.addCategory(Intent.CATEGORY_OPENABLE)
            contentSelectionIntent.type = "image/*"
        }
