How to store image retrieved from url in a SQLite database?

Question

I am retrieving images from a url. Instead of caching the images, would it by any chance be possible to store it in a SQLite database?

                /**

protected Drawable Imagehandler(String url) {
        try {
            url=url.replaceAll(" ", "%20");
            InputStream is = (InputStream)this.fetch(url);
            Drawable d = Drawable.createFromStream(is, "src");
            return d;
        } catch (MalformedURLException e)
        {   
            System.out.println(url);
            System.out.println("error at URI"+e);
            return null;
        } 
        catch (IOException e) 
        {
            System.out.println("io exception: "+e);
            System.out.println("Image NOT FOUND");
            return null;
        } 
    }

    protected Object fetch(String address) throws MalformedURLException,IOException {
        URL url = new URL(address);
        Object content = url.getContent();
        return content;
    }   

this will convert your imageUrl to Drawble at runtime, then set the Drawble to Imageview of Gallery

ya you can store image as BLOB in your database,

public static byte[] urlToImageBLOB(String url) throws IOException {
        httpclient = new DefaultHttpClient();
        entity = null;
        httpGet = new HttpGet(url);
        response = httpclient.execute(httpGet);
        if (response.getStatusLine().getStatusCode() == HttpStatus.SC_OK) {
            entity = response.getEntity();
        }
        return EntityUtils.toByteArray(entity);
    } 

To fetch

public static Bitmap getImageFromBLOB(byte[] mBlob) {
        byte[] bb = mBlob;
        return BitmapFactory.decodeByteArray(bb, 0, bb.length);

    }

// to set imageView.setImageBitmap(getImageFromBLOB(cursor.getBlob(object.getColumnIndex("book_thumb"))));

Here's a link to how you store data in external storage: External storage

The link explains where to place files (if you want to use external storage), and how to check if external storage is available.

Edit: How you access files, is explained under the topic "Accessing files on external storage".

You should in API 8, or above invoke getExternalFilesDir() to get a File that represents your applications root directory. You can then read and write the files as you normally do (using e.g. FileWriter and FileReader for text data)
