Answer 1

look this:

Option A:

public static Bitmap getBitmap(String url) {
    Bitmap bm = null;
    try {
        URL aURL = new URL(url);
        URLConnection conn = aURL.openConnection();
        conn.connect();
        InputStream is = conn.getInputStream();
        BufferedInputStream bis = new BufferedInputStream(is);
        bm = BitmapFactory.decodeStream(new FlushedInputStream(is));
        bis.close();
        is.close();
    } catch (Exception e) {
        e.printStackTrace();
    } 
    return bm;
}

Option B:

public Bitmap getBitmapFromURL(String src) {
    try {
        URL url = new URL(src);
        HttpURLConnection connection = (HttpURLConnection) url
                .openConnection();
        connection.setDoInput(true);
        connection.connect();
        InputStream input = connection.getInputStream();
        Bitmap myBitmap = BitmapFactory.decodeStream(input);
        input.close();
        return myBitmap;
    } catch (IOException e) {
        e.printStackTrace();
        return null;
    }
}

Jus run the method in a background thread.
