Asynttak-tsarin

Tsarin Asynctask-Tsarin ASYNCHAMG na Android yana ba da hanyar da ta dace don sadarwa tsakanin babban zaren da rufin bango. It works by passing the result of a background method to the onPostExecute method, which then receives the result from the background method. This is a fundamental building block of Android programming.

AsyncTask is an abstract class that provides the basic framework for asynchronous tasks. There are three major methods in AsyncTask. The first, onPreExecute, runs on the main thread, preparing the loading dialog and warning the user that a task is about to begin. Hanya ta biyu, doInBackground, runs on a separate thread in the background.

In addition to being able to execute tasks in the background, AsyncTask also allows applications to publish UI updates while processing background tasks. Because Android Activities run on the main thread, running any I/O or processor-intensive tasks on this thread can stall the UI. Asyntask yana ba da tsarin masu haɓaka aikace-aikace na Android don aiwatar da ayyuka waɗanda za a aiwatar da su akan zaren bango kafin babban zaren ya kammala aikinta.

Another advantage of native apps is the ability to control their size, orientation, and resolution. Since native apps are optimized for the OS, they can be targeted to the right device, which makes them faster. Misali, the Facebook application was once written in HTML5 code and was significantly slower on iPhones. In response to this, Facebook app developers decided to develop separate code for the iOS platform. This gave Facebook the ability to optimize the code to run faster on iOS devices.
