How to pass result from onpostexecute method to another activity using intent

Question

How i pass the result obtained from onpostexecute method to another activity or into oncreate method using intent

Send a bundle of data with the intent, then in the new Activity catch it by overriding the onNewIntent() method. — cYrixmorten, Mar 18 '14 at 10:06

Check this link to get result to main activity. Once you got the result, you can pass it to next activity: http://stackoverflow.com/questions/12575068/how-to-get-the-result-of-onpostexecute-to-main-activity-because-asynctask-is-a — Lokesh, Mar 18 '14 at 10:09

public void onPostExecute(String result){

     Intent intent = new Intent(ThisActivity.this, TargetActivity.class);
     intent.putExtra("YourData", result);
     StartActivity(intent)

}

and get it in another activity via getIntent()

Use WeakReference class:

public static class LoginTask extends AsyncTask<String, Integer, Boolean> {
    WeakReference<Activity> mActivityReference;

    public LoginTask(Activity activity){
        this.mActivityReference = new WeakReference<Activity>(activity);
    }

    @Override
    protected Boolean doInBackground(String... params) {

         boolean sucess;

         //do some stuff

         return sucess;
    }

    @Override
    protected void onPostExecute(Boolean result) {
        if (result && mActivityReference.get() != null) {
            Activity activity = mActivityReference.get();
            activity.startActivity(new Intent(activity, MainViewActivity.class));
        }
    }
}
