But now able to use .mp3 files from main expansion file like:

AssetFileDescripto assetFileDescriptor = zipResourceFile.getAssetFileDescriptor( 
  "assets/all_types_of_people1.mp3");
mediaPlayer = new MediaPlayer();
mediaPlayer.setDataSource( assetFileDescriptor.getFileDescriptor(), 
  assetFileDescriptor.getStartOffset(),assetFileDescriptor.getLength());

But how can we use images from main expansion file to WebView?

Since one can get a stream from a zipResourceFile, one can use BitmapFactory to create images from them.

InputStream is = zipResourceFile.getInputStream("myFilePath.jpg");
BitmapFactory.Options bfo = new BitmapFactory.Options();
bfo.inPreferredConfig = Bitmap.Config.ARGB_8888;
Bitmap b = BitmapFactory.decodeStream(is, null, bfo);

Note that since decoding will take some time, you'll want to do this out of the UI thread.

any clue for accessing html files from OOB file like how we access the html from webview Ex: WebView wv = (WebView)this.findViewById(R.id.splashWebView); wv.loadUrl("file:///android_asset/html_no_copy/test.html"); or how to unzip or extract all data from OBB file? – LOG_TAG Aug 01 '12 at 04:28

dagalpin already given a way how to get as InputStream.

Read your HTML file and convert it to UTF-8 String.

and load as below.


// you can also load from an HTML string:
 String summary = "<html><body>You scored <b>192</b> points.</body></html>";
 webview.loadData(summary, "text/html", null);
 // ... although note that there are restrictions on what this HTML can do.
 // See the JavaDocs for loadData() and loadDataWithBaseURL() for more info.

I have not tested it. But it seems to be working.

Instead of only image name use expansionfiles/myFilePath.jpg

InputStream is = zipResourceFile.getInputStream("expansionfile/myFilePath.jpg");
