How to pass Context to AsyncTask?

Question

How to pass context in Async Task class which is coded in different java file from Main Activity but it called from main activity?

Below is

Answer 1

You can just pass the context in the constructor of your AsyncTask.

MyAsyncTask.java

public class MyAsyncTask extends AsyncTask {

    private final Context mContext;

    public MyAsyncTask(final Context context) {
         mContext = context;
    }
}

and then just use the mContext variable in your onPostExecute() method.

When you call your AsyncTask from your MainActivity, you pass the context to the constructor of MyAsyncTask.

MainActivity.java

final MyAsyncTask task = new MyAsyncTask(getApplicationContext());
task.execute();
