Toast fails to show when within a AsyncTask

I have a simple application which sends an image (Base64 encoded) to a server, the server gets this data fine because the PHP script sends me an email with the Base64 Data attached. However, after the task gets completed the toast nev开发者_运维百科er shows. How do I take the Toast get shown after the data gets posted?

I think the issue is within the context.

UPDATE

I have updated the link, because i have since moved the upload logic into a different .java file.

Your sample look OK. If Activity, to which mContext variable belongs is currently active, it should show. Not in other case.

try this modification:

new UploadImage(ImageUploadActivity.this).execute(sentImage);

Android toast.makeText context error

EDIT: WRONG TYPE DECLARATION OF AsyncTask
your AsyncTask declaration looks like class UploadImage extends AsyncTask<String, Void, String>

This means:

• is type of params to doInBackground(String... arg)
• is type of progress
• is type of result from doInBackground to onPostExecute

So change your onPostExecute declaration to this:

protected void onPostExecute(String result)

or change return type of doInBackground to <Bitmap> and change class declaration to: class UploadImage extends AsyncTask<String, Void, Bitmap>
