onPostExecute not allowing me to create Toast message

Question

Please see this before for context: Anonymous Uploading File object to Imgur API (JSON) gives Authentication Error 401 (it has the code for doInBackground() method in case anyone is interested)

Using an AsyncTask class, I am uploading an image to Imgur. The uploading process is done within doInBackground() method. It returns String link to onPostExecute which should display the link in the form of a Toast message.

@Override
protected void onPostExecute(String result) 
{
    super.onPostExecute(result);
    Toast.makeText(getApplicationContext(), "Uploaded! Link: " + result, Toast.LENGTH_SHORT).show();
}

However, doing this gives the following error:

The method getApplicationContext() is undefined for the type UploadToImgurTask

Trying to copy the return string to the clipboard gives a similar issue.

@Override
protected void onPostExecute(String result) 
{
    super.onPostExecute(result);
    ClipboardManager clipboard = (ClipboardManager)getSystemService(Context.CLIPBOARD_SERVICE); 
    ClipData clip = ClipData.newPlainText("label", "Text to copy");
    clipboard.setPrimaryClip(clip);
}

The method getSystemService(String) is undefined for the type UploadToImgurTask

Answer 1

@Raghunandan is right. So, inside your UploadToImgurTask class you can have:

private Context context;
//in constructor:
public UploadToImgurTask(Context context){
        this.context=context;
}

Then in onPostExecute you can simply use:

Toast.makeText(context, "Uploaded! Link: " + result, Toast.LENGTH_SHORT).show();

Hope this helps you.

Answer 2

In place of getApplicationContext(), use AsyncTask's Parent class name with ".this" like MyActivity.this if it extends from Activity Otherwise use getActivity(). Hoping your problem will be solved with this

Answer 3

try this code

public static void pushprofList(Activity context){
 static Context = mConext;

protected void onPostExecute(String result) {

      Toast toast=Toast.makeText(mConext,"Succefully Updated Profile",Toast.LENGTH_LONG);
             toast.show();

    }
  }

this working completely and display toast message.
