Question

So I have a API issue. So i am creating a class that utilizes AndroidHttpClient to download Bitmap images from my server. Problem is, its API Level is 8 and I want this to be used from API 1 and above. Now I know I can use DefaultHttpClient (the API is Level 1) but is there a way I can use both, being distinguished by Build.VERSION.SDK (btw thanx for the quick respose, Konstantin Burov and iandisme).

So for example, if my device is 2.2 I use AndroidHttpClient, anything else use DefaultHttpClient.

Of course if I import the library it will give me an error on any device 1.5 to 2.1.

Any suggestions would greatly be appreciated, because in the future I would want to set other preferences based on API.

I would do this by having two classes, each implementing an interface with the methods you need. Let’s call the interface BitmapDownloader, and the two classes Downloader1 and Downloader2 (I know the class names suck but I’m not feeling terribly creative).

Downloader1 will import and use the old libraries, and Downloader2 will import and use the new ones. Your code would look something like this:

BitmapDownloader bd;
int version = Integer.parseInt(Build.VERSION.SDK);

if (version >= Build.VERSION_CODES.FROYO){
    bd = new Downloader2();
} else {
    bd = new Downloader1();
}

bd.doBitmapDownloaderStuff();
