    If you getting "Not allowed to load local resource: file:///android_asset/index.html" error most probably your problem is putting assets folder in wrong location.

    For gradle project store your assets folder under src/main/ directory by the java and res folders. Like this:

    project-folder -|project_name
    --|build
    --|src
    ---|assets
    ---|gen
    ---|java
    ---|res

    For maven project store yout assets under res/ directory

    webview.loadDataWithBaseURL( "file:///android_asset/", html, "text/html", 
"utf-8", null );

     String htmlStr="<html>..your html data in string..\"data/replace.js\" </html>";
 if (htmlStr.contains("\"data/replace.js\"")) {
     String html = data.replace("\"data/replace.js\"", "\"file:///storage/emulated/0/documents/HtmlContent/new_replace.js\"");
     ((Activity) mContext).runOnUiThread(() -> {
            loadDataWithBaseURL("file:///storage/emulated/0/documents/HtmlContent/", html, "text/html", "UTF-8", "");
      });
  }

    Try following code to load Html content from sdcard.

     String fileName = "something.html";
 File lFile = new File(Environment.getExternalStorageDirectory() + fileName);
 webview.loadUrl("file:///" + lFile.getAbsolutePath());

    to fix this create a folder in "main" called "android_asset" and inside android_asset folder create another folder called "assets" and place your html file in assets and call using this mWebView.loadUrl("file:///android_asset/YOUR HTML FILE.html");

    I had the same problem and even though I dont call mWebView.loadUrl("file:///android_asset/assets/YOUR HTML FILE.html"); it still some how works. which i find strange because thats where the html actually is!

    So again your folders should look like this main/android_assets/assets/YOUR HTML.html and call with mWebView.loadUrl("file:///android_asset/YOUR HTML FILE.html");

    Heres how my oncreate looks.

    public class MainActivity extends ActionBarActivity {

    private WebView mWebView;



@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    mWebView = (WebView) findViewById(R.id.activity_main_webview);
    // Enable Javascript
    WebSettings webSettings = mWebView.getSettings();
    webSettings.setJavaScriptEnabled(true);
    mWebView.loadUrl("file:///android_asset/index.html");

}

    try this :

    this.loadUrl("file:///android_asset/www/js/test.js");

    but there should be one folder name www->js in your assets folder.
