What's the difference between the various methods to get a Context?

Question

In various bits of Android code I\'ve seen:

 public class MyActivity extends Activity {
    public void method() {
       mContext = this;    // since Activi         


        

Answer 1

In some cases you may use Activity context over application context when running something in a thread. When thread completes execution and you need to return the result back to the caller activity, you need that context with a handler.

((YourActivity) context).yourCallbackMethod(yourResultFromThread, ...);
