I am having one java class in that class as soon some one purchases our application then it will start downloading and progress dialog has to appear instead it goes to some other page and when i come out of the application and when i restart then it starts downloading. I want to start downloading as soon as user purchases our application from in-App. My DownloadActivity.java in which this window leaked error occurs is as follows

public class DownloadActivity extends Activity implements OnClickListener { private Context mContext = this;

//private static ProgressDialog pDialog;

private LocalBroadcastManager mLocalBroadcastManager;

private String extention = ".png";

private int i = 0;

private SharedPreferences mediaPrefs = null;
