Android Downloading File by Showing Progress Bar

When our application does a task that takes a considerable amount of time, it is common sense to show the progress of the task to the user.
This is a good User Experience practice. In this tutorial i will be discussing the implementation of a process-progress dialog.

As an example, i am displaying a progress bar that runs while the app downloads an image from the web. You can download any type of file by using tis code ex.(pdf,png).
You have to change file_url value and in java file sdcard path e.g.(downloadedfile.png).

1) Create a new project and fill all the details. File ⇒ New ⇒ Android Project

2) Main.xml

 

3) MainActivity.java

 

4)  AndroidManifest.xml
