The WebView method to load our file takes a URI , so we need to access the HTML file using that URI . Since we stored it in the assets folder, we can access it using file:///android_asset/{file_name} .
You can use a local web server in your Android phone itself. There are many server apps out there in the Play Store, one such app is Simple HTTP Server. You can put your documents into the folder Android/data/com. android.
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
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());
In this case, using WebView#loadDataWithBaseUrl() is better than WebView#loadUrl()!
webView.loadDataWithBaseURL(url,
data,
"text/html",
"utf-8",
null);
url: url/path String pointing to the directory all your JavaScript files and html links have their origin. If null, it's about:blank. data: String containing your hmtl file, read with BufferedReader for example
