目录名称应该是 assets 不是 android_assets

像这样： app-> New-> Folder-> Assets文件夹

现在将 .html 文件放在资产文件夹中。

就是这样。完成。

剩余的代码与您所做的一样。

  WebView视图=新的WebView（this）; 
 view.getSettings（）。setJavaScriptEnabled（true）; 
 view.loadUrl（file：///android_asset/hello.html）; 
 setContentView（view）; 
 

I'm using Android Studio/Gradle.

app\src\main\android_asset folder has the file called chart.html..

I'm trying to load this file to my webview like this:

WebView view = new WebView(this);
view.getSettings().setJavaScriptEnabled(true);
view.loadUrl("file:///android_asset/chart.html");
setContentView(view);

But I always get the error: could not be loaded because ERR_FILE_NOT_FOUND.

What am I missing here?

The directory name should be assets not android_assets

Do like this:

As shown in the above pics just right click on your app->New->Folder->Assets Folder

Now put your .html file here in assets folder.

That's it. Done.

Remaining is same in code what you did.

WebView view = new WebView(this);
view.getSettings().setJavaScriptEnabled(true);
view.loadUrl("file:///android_asset/hello.html");
setContentView(view);
