Question

I wrote a splash activity with an async call to download JSON from a URL. In onPostExecute I get JSON as a result. Now I need to pass that JSON to a new activity to parse and display it in listView. Do I need to start that new activity before or after I have passed the JSON?

Answer 1

You can make the resulting JSON available to the new activity by using putExtra in onPostExecute right before starting the new activity.

Intent intent = new Intent(this, yourClass.class);
intent.putExtra("json", json);
// Now start your activity

You can then get the json by calling getString in your new activity.

Bundle extras = getIntent().getExtras();
jsonString = extras.getString("json");
