13 - JSON Parsing, NetworkOnMainThreadException, AsyncTask - Android Studio

We get a NetworkOnMainThreadException if try to make a network call on main thread, we will also see how we can resolve this exception in Android.

AsyncTask is ideal for short operations (a couple of seconds), For long running tasks in the background use a services in Android.

Finally we will run our app and will parse result.

Sir, you are one of the best teachers I've ever come across. You not do it, but deliberately run into exceptions and errors so we can understand it. Being a software development student, there is a big difference between writing a functioning code and understanding the elements that make one's code to function. That's why you are an exception. I'm going back to click the subscribe button....Thank you.

Very good work. Thank you for the lesson. I am very new at this. I only had one problem: my emulator was in Airplane Mode and would not allow me to connect to the text file.

Do not worry about the few mistakes. Most of us make far far more than you made. They do not detract from your presentation and it is good for us new people to see how you go about tracking them down and correcting them.

[Ashirgaziyev]

Hi! Thank you very much for the helpful tutorial!

I implemented all the steps carefully, but still getting the same error after providing permission for the Internet.

Do you know what might happen? Why does it still show the same error even after I gave permission?

Thanks!

[sophiietela]

hi i wrote the same code but in the final fonction i mean this one :

protected void onPostExecute(String result) {
super.onPostExecute(result);
tvData.setText(result);
}

it says that it cant resolve tvData even if i ve already written private TextView data;

[gauravramakrishna]

Hi, I am new to android development. Is there a way to post data from your app to the server in JSON format? Thanks.

[undead]

for the tvData, I do exactly what you showed in the tutorial, but it still doesn't detect it in the onPostExecute.
