How to decode bitmap from cache file and from web

Question

I am using this method to retrieve a bitmap

 private Bitmap getBitmap(String url) 
{
    File f=fileCache.getFile(url);

    //from SD cache


    if(b!=null)
        return b;

    //from web
    try {
        Bitmap bitmap=null;
        Log.e("URL", url);
        URL imageUrl = new URL(url);
        HttpURLConnection conn = (HttpURLConnection)imageUrl.openConnection();
        conn.setConnectTimeout(30000);
        conn.setReadTimeout(30000);
        InputStream is=conn.getInputStream();
        OutputStream os = new FileOutputStream(f);
        Utils.CopyStream(is, os);
        os.close();

        return bitmap;
    } catch (Exception ex){
       ex.printStackTrace();
       return null;
    }
}

As you see above how do i decode the bitmap from SDcard or cache and from the get from web code? Ive tried one method but it didnt work.

Well for the file part take a look here. Look specifically at decodeFile.

As for the Url Image take a look here for a small tutorial on it.
