Question

In my Application I have 3 Activities:

1. Login

2. AsyncTask (different class)

3. Welcome

After receiving all the information in the Login Activity it moves to the AsyncTask Activity. When the the AsyncTask is completed it moves to the Welcome Activity. I want to close the Login Activity as soon as the AsyncTask Activity completes its job..

I am trying to use the following code in the onPostExecite() of AsyncTask:

Login.this.finish();

But I am getting an error of: No enclosing instance of the type of Login is accessible in scope..

Please tell me how can i close my Login Activity after completing my AsyncTask..

Thanks in Advance…

As AsyncTaskActivity is in separate file than LoginActivity, you cant finish LoginActivity by:

Login.this.finish();

Instead you should pass the Activity Reference as parameter in the AsyncTaskActivity Class, like you can define following constructor:

private class AsyncTaskActivity extends AsyncTask<String, Void, String> {

Activity mActivity;
    public AsyncTaskActivity(Activity activity)
    {
         super();
         this.mActivity=activity;
    }
}

and whenever you want to finish the activity call

this.mActivity.finish();

Create AsyncTaskActivity’s Object in LoginActivity by

AsyncTaskActivity asynTask = new AsyncTaskActivity(LoginActivity.this);
