Android – Loading html file from local folder into webview

androidandroid-webviewhtml

I'm new to Android development.

I want to load a html file into a webview.

Note that there are so many relevant questions on SO like this, but they all deal with getting **.html* from assets folder.

But I want to load html file from local folder, say "D://abc.html" because if my html is around 10Mb then corresponding apk size also goes upto 10mb.

Any help appreciated.

EDIT

I tried webView.loadUrl("file:///D:/Projects/myWebsite/index.html");

but it gives Web page not available and File not found error.

You can use:


   WebView webView = // ...

   webView.loadUrl("file:///myPath/myFile.html");

In an Android application, files can be read from 3 types of locations:

Internal storage: Each app has its own, file names are relative to this location. URL takes form file:///myFolder/myFile.html
External storage: Needs permission and may not always be available. Get the root folder by calling Environment.getExternalStorageDirectory(). So, construct the URL using: String url = "file:///" + Environment.getExternalStorageDirectory().toString() + File.separator + "myFolder/myFile.html"
Assets: Stored in the apk. Read-only access. URL takes form file:///android_asset/myFolder/myFile.html (See also Loading an Android Resource into a WebView)

Extend WebViewClient and call onPageFinished() as follows:

mWebView.setWebViewClient(new WebViewClient() {

   public void onPageFinished(WebView view, String url) {
        // do your stuff here
    }
});

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.
