Loading existing .html file with android WebView

Solution 1:

ok, that was my very stupid mistake. I post the answer here just in case someone has the same problem.

The correct path for files stored in assets folder is file:///android_asset/* (with no "s" for assets folder which i was always thinking it must have a "s").

And, mWebView.loadUrl("file:///android_asset/myfile.html"); works under all API levels.

I still not figure out why mWebView.loadUrl("file:///android_res/raw/myfile.html"); works only on API level 8. But it doesn't matter now.

Solution 2:

If your structure should be like this:

/assets/html/index.html

/assets/scripts/index.js

/assets/css/index.css

Then just do ( Android WebView: handling orientation changes )

    if(WebViewStateHolder.INSTANCE.getBundle() == null) { //this works only on single instance of webview, use a map with TAG if you need more
        webView.loadUrl("file:///android_asset/html/index.html");
    } else {
        webView.restoreState(WebViewStateHolder.INSTANCE.getBundle());
    }

Make sure you add

    WebSettings webSettings = webView.getSettings();
    webSettings.setJavaScriptEnabled(true);
    webSettings.setJavaScriptCanOpenWindowsAutomatically(true);
    if(android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.JELLY_BEAN) {
        webSettings.setAllowFileAccessFromFileURLs(true);
        webSettings.setAllowUniversalAccessFromFileURLs(true);
    }

Then just use urls

<html>
<head>
    <meta charset="utf-8">
    <title>Zzzz</title>
    <script src="../scripts/index.js"></script>
    <link rel="stylesheet" type="text/css" href="../css/index.css">

Solution 3:

paste your .html file in assets folder of your project folder. and create an xml file in layout folder with the fol code: my.xml:

<WebView  xmlns:android="http://schemas.android.com/apk/res/android"
  android:id="@+id/webview"
  android:layout_width="fill_parent"
  android:layout_height="fill_parent"
    />

add fol code in activity

setContentView(R.layout.my);
    WebView mWebView = null;
    mWebView = (WebView) findViewById(R.id.webview);
    mWebView.getSettings().setJavaScriptEnabled(true);
    mWebView.loadUrl("file:///android_asset/new.html"); //new.html is html file name.

Solution 4:

Copy and Paste Your .html file in the assets folder of your Project and add below code in your Activity on onCreate().

        WebView view = new WebView(this);
        view.getSettings().setJavaScriptEnabled(true);
        view.loadUrl("file:///android_asset/**YOUR FILE NAME**.html");
        view.setBackgroundColor(Color.TRANSPARENT);
        setContentView(view);
