At least not yet. You'll have to use the Asset Manager. However I don't have any snippet ready and I'm not sure whether there's NDK level access or whether you'd have to use the JNI to call Java stuff.

Afaik there's no "native" way of getting the apk structure. The NDK doesn't offer any class or method for that. You could use a zip-lib (also provided by the NDK) to explore the archieve. Or use a Java-call.
The Asset-Manager and Asset-Dir classes in the NDK only provide access to a file you already know the path of.
I just did exactly that recently (unpack a multi-layer deep asset-folder from the APK), so I'm pretty sure that's the only way (Java or zip-lib). It's easy to find a native snippet of using the Asset Manager to unpack a known directory or file though. There's various samples.

Thank You both for Your answers :) I was looking at AssetManager examples before, but does even SFML give access to the required handles(JNIEnv* env, jobject clazz --- if that's even required or I did not understand the examples)?

Check the test branch I've mentioned on last page. It has a new function that will expose the native handle. Check the included Android example for JNI interaction (that function is still WIP though).

Jup, I'm using the branch Mario mentioned to grab the AssetManager and extract my files.

Another thing - sf::Vertex seems to be not rendering on Android. Is that a known bug?

Does this work on other platforms? Because I'd say a Vertex itself isn't actually drawable.

Sure,

Quote
window.draw(rectangle, 4, sf::Quads);

this works on windows but does not on android.

Android uses OpenGL ES and OpenGL ES doesn't understand quads (which will silently fail at the moment). As a workaround, use some other primitive type.

Thanks, that solved it :) Getting string from resources is also not possible directly through SFML right now?

You should be able to use SFML's InputStream for that, which I think is wrapped to the asset manager.

Well, no, I think You're mistaking assets with resources now :) I'm not too familiar with whole android apk structure, but as far as I understood, strings get compiled with other resources description to resources.arsc and when You're creating a "standard" android apk You simply use @string/app_name to get app_name string, depending on user's language. It could be a neat feature for SFML(if that's even possible through native functions).

Ah ok, I thought you'd like to read strings from a text file. Reading string resources isn't exposed and you'd have to write the code for that yourself.

img.saveToFile("file.png");

not working for me. In LogCat is wrote "failed to save image". I am testing it on android.
If someone have time, pleas check it, because i don't know that this is my mistake or sfml bug.

Maybe You don't have permissions to write to that file? Try that:

<manifest ...>
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
    ...
</manifest>
