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

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 <code>www</code> has a file called <code>index.html</code> located in the <code>assets</code> folder in the root of the project".

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

Consider the code example:

<pre><code>WebView webViewer = (WebView) findViewById(R.id.webViewer);
webView.loadUrl("file:///android_asset/www/index.html");
</code></pre>

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

The URI <code>"file:///android_asset/"</code> points to <code>YourProject/app/src/main/assets/</code>.

Note: <code>android_asset/</code> uses the singular (asset) and <code>src/main/assets</code> uses the plural (assets).

Suppose you have a file <code>YourProject/app/src/main/assets/web_thing.html</code> that you would like to display in a WebView. You can refer to it like this:

<pre><code>WebView webViewer = (WebView) findViewById(R.id.webViewer);
webView.loadUrl("file:///android_asset/web_thing.html");
</code></pre>

The snippet above could be located in your <a href="http://developer.android.com/reference/android/app/Activity.html" rel="noreferrer">Activity</a> class, possibly in the <code>onCreate</code> method. 

Here is a <a href="http://developer.android.com/tools/projects/index.html" rel="noreferrer">guide</a> to the overall directory structure of an android project, that helped me figure out this answer.

I'm using Android Studio (Eclipse with ADT could not work properly because of the build problem).

Solution that worked for me:

<ol>
<li>I put the /assets/www/index.html under app/src/main/assets directory. (take care AndroidStudio has different perspectives like Project or Android)</li>
<li>use super.loadUrl("file:///android_asset/www/index.html"); instead of super.loadUrl("file:///android_assets/www/index.html"); (no s)</li>
</ol>

I want to know what does <code>file:///</code> 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.

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

我想知道从android的assets文件夹中加载一个file:///文件是什么意思。它是指向根目录的绝对路径名吗？顺便说一下，我在phonegap的教程中看到了这一点。
