Adding Local Images to An Android Webview

This tutorial demonstrates how to download a web page from the internet, and then modify that web page to use local graphics resources before displaying to the user.

Why Use Local Images?

Perhaps you want your app to dynamically load data from the internet, but you frequently want to display the same images. Using local images can be a good way to cut down on the amount of bandwidth needed for an application and could improve performance.

Why Display Static Pages?

In a previous tutorial, we showed you how to display a web page from within an Android Activity.

This is very useful, but there may be some cases in which you want to take advantage of the html rendering capabilities without having to download a file from the internet.

Why would you want to do this?

1. Your application won't have to require an internet permission
2. Your requested web page will load faster
3. You can use it to display important content (instructions, help files, high scores...) without relying upon an internet connection that could be spotty or non-existent
