Hi Wes,
I tried the way which you are saying. but could not make it working.
It was giving "file not found" exception. Even mine HTML is not
getting loaded. May be I am paasing the wrong URL to my
"LocalFileContentProvider.java"
Can you give some hint how it can be done. or Can you give some sample
code how the URL is paases and send to our
LocalFileContentProvider.java
Anyways I am pasting my code here. Can you see what I am doing wrong
here?
Any ways thanks for all help.
What I have done is:
1- I pushed Google.html / ex.css/ test.jpg file to asset folder

LocalFileAccess.java
----------------------------------------
public class LocalFileAccess extends Activity {
@Override
public void onCreate(Bundle icicle) {
super.onCreate(icicle);
WebView webView = new WebView(this);
setContentView(webView);
Uri uri = Uri.parse("content://
com.android.LocalFileAccess/Google.html");
try {
is = getContentResolver().openInputStream(uri);
byteArray = new byte[is.available()];
read = is.read(byteArray);
System.out.println("Available: " + is.available());
System.out.println("Bytes read: " + read);
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
webView.loadData(new String(byteArray), "text/html", "utf-8");
}
}

LocalFileContentProvider.java
-----------------------------------------------
public class LocalFileContentProvider extends ContentProvider {
private static final String URI_PREFIX = "content://
com.android.LocalFileAccess";
public static String constructUri(String url) {
Uri uri = Uri.parse(url);
return uri.isAbsolute() ? url : URI_PREFIX + url;
}
@Override
public ParcelFileDescriptor openFile(Uri uri, String mode) throws
FileNotFoundException {
//URI u =
URI.create("file:///data/data/com.android.LocalFileAccess/
Google.html");
File file = new File(uri.getPath());
ParcelFileDescriptor parcel = ParcelFileDescriptor.open(file,
ParcelFileDescriptor.MODE_READ_ONLY);
return parcel;
}
// Rest of methods I override, but I did not pasted it
here.
}
____________________________________________________________________
AndroidManifest.xml
----------------------------------------------
<provider android:name="LocalFileContentProvider"
android:authorities="com.android.LocalFileAccess"
android:grantUriPermissions="true"
/>
