Invoking parent private method by reflection

public class SuperClass {

boolean superField = true;

private void superMethod(boolean superField) {
System.out.println("superMethod() called - param:" + superField);
}
}

try {

declaredMethod.setAccessible(true);

declaredMethod.invoke((SuperClass)subClassInstance, new Object[] {false}); //I remember that there was a situation this explicit cast is required

} catch (NoSuchMethodException e) {

MapQuest Android MapView vs Google Android MapView

Problem: Cannot align the MapView properly in MapQuest.

Solution: Do your own bit-wise OR!!!

Google Android MapView LayoutParams:

int a = MapView.LayoutParams.BOTTOM_CENTER; //81

int b = MapView.LayoutParams.BOTTOM; //80

int c = MapView.LayoutParams.CENTER_HORIZONTAL; //1

int d = MapView.LayoutParams.BOTTOM | MapView.LayoutParams.CENTER_HORIZONTAL; // 81

it makes sense, doesn't it?

How about MapQuest Android MapView LayoutParams?

int a = MapView.LayoutParams.BOTTOM_CENTER; //35

int b = MapView.LayoutParams.BOTTOM; //32

int c = MapView.LayoutParams.CENTER_HORIZONTAL; //1

int d = MapView.LayoutParams.BOTTOM | MapView.LayoutParams.CENTER_HORIZONTAL; // 33

hmmm...something doesn't seem right here...
