cordova FileChooser插件获取所选文件的真实路径

Question

我将此插件添加到我的cordova项目中，这使我能够选择文件，然后返回此文件的路径。我的问题是返回的路径不是真正的路径，它是content://media/external/images/media/2144。我想将此URI转换为实际路径，例如storage/sdcard0/DCIM/camera/321321321.jpg 这是java中的插件代码，我应该修改什么？

    private static final String TAG = "FileChooser";
    private static final String ACTION_OPEN = "open";
    private static final int PICK_FILE_REQUEST = 1;
    CallbackContext callback;

    @Override
    public boolean execute(String action, CordovaArgs args, CallbackContext callbackContext) throws JSONException {

        if (action.equals(ACTION_OPEN)) {
            chooseFile(callbackContext);
            return true;
        }

        return false;
    }

    public void chooseFile(CallbackContext callbackContext) {

        // type and title should be configurable

        Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
        intent.setType("*/*");
        intent.addCategory(Intent.CATEGORY_OPENABLE);
        intent.putExtra(Intent.EXTRA_LOCAL_ONLY, true);

        Intent chooser = Intent.createChooser(intent, "Select File");
        cordova.startActivityForResult(this, chooser, PICK_FILE_REQUEST);

                    callback.success(uri.toString());

                } else {

                    callback.error("File uri was null");

                }

            } else if (resultCode == Activity.RESULT_CANCELED) {

                // TODO NO_RESULT or error callback?
                PluginResult pluginResult = new PluginResult(PluginResult.Status.NO_RESULT);
                callback.sendPluginResult(pluginResult);

            } else {
