Load HTML file into WebView
Solution 1:
The easiest way would probably be to put your web resources into the assets folder then call:
webView.loadUrl("file:///android_asset/filename.html");
For Complete Communication between Java and Webview See This
Update: The assets folder is usually the following folder:
<project>/src/main/assets
This can be changed in the asset folder configuration setting in your <app>.iml
file as:
<option name=”ASSETS_FOLDER_RELATIVE_PATH” value=”/src/main/assets” />
See Article Where to place the assets folder in Android Studio
Solution 2:
probably this sample could help:
WebView lWebView = (WebView)findViewById(R.id.webView);
File lFile = new File(Environment.getExternalStorageDirectory() + "<FOLDER_PATH_TO_FILE>/<FILE_NAME>");
lWebView.loadUrl("file:///" + lFile.getAbsolutePath());
