Android Question Threading after jobdone

[Derek Jee]

Hi there..

I need to process the response to a http request in a separate thread. I will receive some json and parse it, then add it to a table in my database. This all needs to be done using a single thread. I have tried using the threading lib but it does not run the sub and process the data. Can anyone supply a little bit of code to help me out?

Thanks..

Derek

You won't be able to update the Table (or anything else in the Gui) from within a thread, you'll need to delegate that to a sub on the main thread using the Threads RunOnGuiThread method.

Hi Steve

Thanks for the reply. So to clarify, I cannot process my response from a http request in a new thread? Processing data from the downloaded files well halt the UI.. Isn't that what the threading lib is enabling me to do or am I missing the point?

Kindest regards

Derek

Yes, you can process the responses, just not update the Gui with the results. You will have to call a sub outside of the thread to do that.

See the attached example.

Note: you cannot debug an application that uses a thread, this will only run in Release mode.

Why do you need to use a background thread?

How large is the json file? Are you correctly inserting the data to the table (in a single transaction)?
