Renaming helps sometimes to prevent such accidents, for instance if
you know the task should always be created from an activity you can do
like this:
*public class MyAsyncTask extends AsyncTask<...> {*
* private Context appContext;*
*
* public MyAsyncTask(Activity activity) {*
* appContext = activity.getApplicationContext();*
* }*
* ...*
*}*
