How to use asynctask to make HTTP GET request?
In Android Studio, use the Gradle entry as: AsyncTask does manage its thread pool, but it is not optimized for network activity. Actually, if you have many HTTP requests to the same server, it is better both in terms of memory consumption and overall performance to keep them on the same thread, and reuse a persistent connection, whenever possible.
Is it possible to run multiple asynctasks at the same time?
There is a limit of how many tasks can be run simultaneously. Since AsyncTask uses a thread pool executor with limited max number of worker threads (128) and the delayed tasks queue has fixed size 10, if you try to execute more than 138 your custom tasks the app will crash with java.util.concurrent.RejectedExecutionException.
How to manage Multiple async tasks efficiently in Java?
Another AsyncTask that aggregates the responses from the network tasks. Perform a sendEmptyMessageDelayed () every, say, 500ms to a Handler created by your Activity that refreshes the data that has come in from the network tasks and continues to do so until all of the networking results are dealt with. A Thread that performs the aggregation.
When to use asynctask as a background task?

How to create an asynchronous HTTP request in Java?
The full implementation to our HTTP GET request is complete. We’ve gone through and implemented, step by step, the process of creating an asynchronous HTTP GET request in Java, using Android’s AsyncTask class. This will allow your app to perform requests while the user interacts with your app’s UI.
How does asynctask work on an Android phone?
Android handles this by a pop-up window asking the user to “wait” until the app responds, or “close” the application due to it being unresponsive. Sounds like that app is getting an instant un-install to me.
Is it better to reuse thread pool in asynctask?
AsyncTask does manage its thread pool, but it is not optimized for network activity. Actually, if you have many HTTP requests to the same server, it is better both in terms of memory consumption and overall performance to keep them on the same thread, and reuse a persistent connection, whenever possible. AsyncTask does not consider such issues.
