Android Question

What does file:///android_assets/www/index.html mean?

I want to know what does

mean while loading a html file from the assets folder in android

Is it an absolute path name which points to the root directory?

I saw this in the tutorial for phonegap by the way.

file:/// is a URI (Uniform Resource Identifier) that simply distinguishes from the standard URI that we all know of too well - http://.

It does imply an absolute path name pointing to the root directory in any environment, but in the context of Android, it's a convention to tell the Android run-time to say "Here, the directory www has a file called index.html located in the assets folder in the root of the project".

That is how assets are loaded at runtime, for example, a WebView widget would know exactly where to load the embedded resource file by specifying the file:/// URI.

Consider the code example:

WebView webViewer = (WebView) findViewById(;

A very easy mistake to make here is this, some would infer it to as file:///android_assets, notice the plural of assets in the URI and wonder why the embedded resource is not working!
