I searched for good REST / HTTP Clients for Android-Development, but I did not found something that meets my needs.
Now I have a question. Is there a good way to reuse HTTP client-objects in an android project?
It would be good if there is a central place (maybe static class?) to access an httpclient to do request (async)...
How can I do this in an android project?
Same thing for my credentials. (I use basic auth and do not want to pass the credentials from activity to activity)
I would recommend you RoboSpice:
RoboSpice is a modular android library that makes writing asynchronous network requests easy.
It does have a cache manager, and works as service, which is, to me, better than common AsyncTasks.

Also, you should not touch the R class, it is automatically built from your ressources.
I suggest checking out

I would also suggest a minor improvement change RESTLoader.RESTResponse data so as data be the final data in that case List<String> so as the parsing moved to the acync loader and avoid latency on UI thread. Adding the code pointing out the suggestions for change.
@Override
public void onLoadFinished(Loader<RESTLoader.RESTResponse> loader, RESTLoader.RESTResponse data) {
int code = data.getCode();
String json = data.getData(); // <-- (change) this should be the final data
// Check to see if we got an HTTP 200 code and have some data.
if (code == 200 && !json.equals("")) {
// For really complicated JSON decoding I usually do my heavy lifting
// Gson and proper model classes, but for now let's keep it simple
// and use a utility method that relies on some of the built in
// JSON utilities on Android.
List<String> tweets = getTweetsFromJson(json); // <-- (change) that parse move to loader
// Load our list adapter with our Tweets.
mAdapter.clear();
for (String tweet : tweets) {
mAdapter.add(tweet);
}
}
else {
Toast.makeText(this, "Failed to load Twitter data. Check your internet settings.", Toast.LENGTH_SHORT).show();
}
}
As said RoboSpice is a very good choice. If you want to simply keep your local resource syncronized with remote data you can use RestDroid which is a "resource oriented" library to handle asynchronous REST request.
