What does file:///android_asset/www/index.html mean?
提问by Nav
I want to know what does file:///mean while loading a html file from the assets folder in android
我想知道file:///从 android 中的资产文件夹加载 html 文件是什么意思
Is it an absolute path name which points to the root directory?
它是指向根目录的绝对路径名吗？
I saw this in the tutorial for phonegap by the way.
顺便说一下，我在 phonegap 的教程中看到了这个。

file:///is a URI (Uniform Resource Identifier) that simply distinguishes from the standard URI that we all know of too well - http://.
file:///是一个 URI（统一资源标识符），它只是与我们都非常熟悉的标准 URI 区分开来 - 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 wwwhas a file called index.htmllocated in the assetsfolder in the rootof the project".
它确实意味着一个指向任何环境中根目录的绝对路径名，但在 Android 的上下文中，它是一种约定，告诉 Android 运行时说“这里，该目录www有一个名为index.html的assets文件，位于项目的根”。
That is how assets are loaded at runtime, for example, a WebViewwidget would know exactly where to load the embedded resource file by specifying the file:///URI.
这就是在运行时加载资产的方式，例如，WebView小部件将通过指定file:///URI确切知道在哪里加载嵌入的资源文件。
Consider the code example:
考虑代码示例：
WebView webViewer = (WebView) findViewById(R.id.webViewer);
webView.loadUrl("file:///android_asset/www/index.html");
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!
这里很容易犯的一个错误是，有些人会推断它为 as file:///android_assets，注意 URI 中的资产复数，并想知道为什么嵌入的资源不起作用！

If someone uses AndroidStudio make sure that the assets folder is placed in
如果有人使用AndroidStudio，请确保将assets文件夹放在
app/src/main/assets
directory.
应用程序/源代码/主/资产
目录。

The URI "file:///android_asset/"points to YourProject/app/src/main/assets/.
URI"file:///android_asset/"指向YourProject/app/src/main/assets/.
Note: android_asset/uses the singular (asset) and src/main/assetsuses the plural (assets).
注意：android_asset/使用单数（资产）和src/main/assets使用复数（资产）。
Suppose you have a file YourProject/app/src/main/assets/web_thing.htmlthat you would like to display in a WebView. You can refer to it like this:
假设您有一个YourProject/app/src/main/assets/web_thing.html要在 WebView 中显示的文件。你可以这样引用它：
WebView webViewer = (WebView) findViewById(R.id.webViewer);
webView.loadUrl("file:///android_asset/web_thing.html");
The snippet above could be located in your Activityclass, possibly in the onCreatemethod.
上面的代码片段可能位于您的Activity类中，也可能位于onCreate方法中。
Here is a guideto the overall directory structure of an android project, that helped me figure out this answer.

It took me more than 4 hours to fix this problem. I followed the guide from http://docs.phonegap.com/en/2.1.0/guide_getting-started_android_index.md.html#Getting%20Started%20with%20Android
我花了4个多小时才解决这个问题。我遵循了http://docs.phonegap.com/en/2.1.0/guide_getting-started_android_index.md.html#Getting%20Started%20with%20Android 中的指南
I'm using Android Studio (Eclipse with ADT could not work properly because of the build problem).
我正在使用 Android Studio（由于构建问题，带有 ADT 的 Eclipse 无法正常工作）。
Solution that worked for me:
对我有用的解决方案：
I put the /assets/www/index.html under app/src/main/assets directory. (take care AndroidStudio has different perspectives like Project or Android)
use super.loadUrl("file:///android_asset/www/index.html"); instead of super.loadUrl("file:///android_assets/www/index.html"); (no s)
我把 /assets/www/index.html 放在 app/src/main/assets 目录下。（注意 AndroidStudio 有不同的视角，如 Project 或 Android）
使用 super.loadUrl("file:/// android_asset/www/index.html"); 而不是 super.loadUrl("file:/// android_assets/www/index.html"); （无小号）
回答by Mahmoud Abdelwahab
it's file:///android_asset/... not file:///android_assets/... notice the plural of assets is wrong even if your file name is assets
它是 file:/// android_asset/... 不是 file:/// android_assets/... 请注意即使您的文件名是资产，资产的复数也是错误的
