There isn’t something like MonoDroid [Acitvity()] attribute/annotation for Android Java SDK? While it is not strange thing in Java (for example WebServlet annotation) it is not possible to have something like that in Android Java SDK?
In fact, I am tired of editing AndroidManifest.xml!
All of your activities must, in fact, be declared in the manifest. I haven’t seen any way to get around this so far. Of course, you could imagine some sort of tool that did post processing on your application (via Eclipse or something like that) and generated your manifest for you. However, I haven’t seen such a thing, and doubt such a thing exists. Instead, people typically just declare them in the manifest (it takes a few seconds at most), or create them in Eclipse and let it do the “dirty work.”
