Hi there In the Dev Guide section on Building Custom Components (http:// developer.android.com/guide/topics/ui/custom-components.html), we read:
* It is static, meaning it does not generate the so-called "synthetic methods" that allow it to access data from the parent class, which in turn means that it really behaves as a separate class rather than something strongly related to NoteEditor. This is a cleaner way to create inner classes if they do not need access to state from the outer class, keeps the generated class small, and allows it to be used easily from other classes. This mischaracterizes the difference between static and non-static (inner) nested classes. The generation of synthetic methods is not related to whether the class is static or not, but to the visibility of the object being accessed in the "other" class (it works both from inner to outer and vice versa). If the outer (inner) class defines a private method or field, then when it's accessed from within the inner (outer) class, a hidden accessor method will be generated on the outer (inner) class to cross the "private" boundary. Of course, if the inner class is static, the outer field or method being accessed would also have to be static. Making the nested class static does not in itself avoid the generation of any synthetic methods: if any of them are private, those accessors will be generated regardless. What a non-static nested class DOES generate is a hidden reference to the outer instance, in order for its fields and methods to be accessed, but that access doesn't require the generation of synthetic methods unless their visibility demands it. It's a small but important error in the documentation, and it would be nice to see it fixed.
