How to change a variable of an AsyncTask in an activity from another activity by a button click in android studio?

I am using an AsyncTask in my MainActivity in Android Studio, where in doInBackground method, I have an URL, that I want to be changed from a list view item, which is loaded to a listView in HomeActivity.
Is it possible to change the value of the URL to the value of the list item? So I will get a Unique URL every time I click on a list item.
My MainActivity:

Here I want the address value in the listView to be transferred to the URL value in MainActivity

First of all why AsyncTask? Its already deprecated and comes with many issues. https://developer.android.com/reference/android/os/AsyncTask
You can simply use coroutines. its super easy and less complicated. or you can even use rxjava.
Secondly, your AsyncTask is designed in a wrong way.
Do the following.
Define your async task to take strings
public class ProcessInBackground extends AsyncTask<String, Void, Exception> {
then your doInBackground will look something like this:
#Override
protected Exception doInBackground(String... strings) {
URL url = new URL(strings[0]);
}
execute the asyncTask by calling it this way.
new ProcessInBackground().execute("pass_your_url_from_list");
Just dont use AsyncTask.

Google maps showing logo, but not displaying in Android emulator

My app is supposed to display a Google Map with a heatmap, but I can't even get the map to display. It's only showing the logo in the bottom left corner. There seems to be no errors. I also checked the gradle and all the necessary dependencies are there. I can't tell if this is due to an actual error or lack of memory/slow processing.

identify incoming caller android and display in toast

I'm trying to build a simple phonebook application where I can perform a search and an API will return the information. So far this is the part that I've got working.
I also want incoming caller to be identified with the same API, that would require the incoming number from Broastcastreceiver to be put into the API query and the returned information should be displayed in a toast. This is the part I'm having problems with.
So far this is what I have. Apologize if its really messy, this is what I've been playing around with recently and made small adjustments. Also its alot of copy-paste, I'm a beginner at java/Android and trying to learn.

The problem is that there's a lot of items, and most of them have the resources, but some don't and i would like to just skip those who don't have, but the main problem is that the app crashes while trying to see the bank.

You can't change Views in a non UI thread.
So in order to fix your problem just access UI related stuff in the UI thread, e.g. in onPostExecute()

Do not do this : View should not be touched in another thread except UI thread.

I've never seen this error before! What is the problem?
Any help is much appreciated ! Thanks

Edit:
I tried the same JSON, but just in a txt file strongpixel.com/java/JSON.txt, this works without any problem, it takes some time to load, but it works.

You can't get it work cause your code can't load proper JSON String. There is only one place where you make download:
JSONfunctions.getJSONfromURL(params[0])
You get the obvious error: JSON object can't be created from string like <!doctype html>. It means that you download HTML data instead of JSON. For simple test you can try next code and you will get the same error:
JSONObject object = new JSONObject("<!DOCTYPE html>");
You can get this wrong response from numerous reasons: wrong request, your fire wall, proxy, even server might return wrong result if you don't specify User-Agent header or doesn't perform authorization. I do recommend using some web debug tools that will help you to handle such situations and make sure that your app receive valid data.
If you are using Windows i would recommend you to use Fiddler, it is free. Here is example how you can setup fiddler for your test device: http://www.cantoni.org/2011/06/28/debug-http-android-fiddler
Anyway there is alternative tools for other operating system.

I got it working! It was a simple and idiotic mistake. The server i was connecting to didnt allow POST so in the adapter i changed Httppost to Httpget
