Get value from protected void class

i´m going my first steps in java: I have the following problem. From my protected class 'onActivityResult' I need to have the String in my class 'ImageUploadTask'. How can I do this?

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    switch (requestCode) {
    case PICK_IMAGE:
        if (resultCode == Activity.RESULT_OK) {
            Uri selectedImageUri = data.getData();
            String filePath = null;

            try {
                ...

                } else if (filemanagerstring != null) {
                    filePath = filemanagerstring;
                } 
                if (filePath != null) {
                    decodeFile(filePath);
                    // get fileName //
                    String fileName = new File(filePath).getName();
                    Log.e(TAG, "Filename:" + fileName);


                } 
        break;
    default:
    }
}

class ImageUploadTask extends AsyncTask<Void, Void, String> {
    private static final String TAG = "GalleryPreviewView";

    @Override
    protected String doInBackground(Void... unsued) {
        try {
            ....
                     Log.e(TAG, "Filename:" + fileName);
        }

    }

    @Override
    protected void onProgressUpdate(Void... unsued) {

    }

}

Probably you want to pass fileName variable to your AsyncTask subclass. You have a few options:

You can declare "class-scope" variable and only initialise it in your onActivityResult method:

if (filePath != null) {
   decodeFile(filePath);
   fileName = new File(filePath).getName();
   Log.e(TAG, "Filename:" + fileName);
}

and then pass variable to AsyncTask class like this:

class ImageUploadTask extends AsyncTask<String, Void, String> {
    private static final String TAG = "GalleryPreviewView";

    @Override
    protected String doInBackground(String... params) {
       String fileName = params[0];
    }

An usage:

ImageUploadTask task = new ImageUploadTask();
task.execute(fileName);

But since your ImageUploadTask is probably inner class of your Activity class, you have direct access to all variables declared in "parent" class.

If you are using ImageUploadTask as an embedded class of your activity class then you can do this:

MyActivityClass.this.activityfunction();

or 

MyActivityClass.this.activityFieldVariable;
