I'm new to Android development. There seem to be 2 important classes when dealing with threading in Android: Looper and Handler. There are static Looper.myLooper() and Looper.getMainLooper() methods to get the current thread's looper and the UI thread's looper, respectively. However, there are no such static methods for Handler. If you want to post to the UI thread, for example, code samples suggest doing this:
new Handler(Looper.getMainLooper()).post(new Runnable() { ...
Why doesn't Handler expose a cached, static getMainHandler() method that looks like this? Wouldn't that avoid creating unnecessary garbage?
private static final Handler mainHandler = new Handler(Looper.getMainLooper());
public static Handler getMainHandler() { return mainHandler; }
