Xposed Abstract Methods and Interfaces

Question

Is Xposed able to hook abstract methods and/or methods defined in interfaces? I am trying to hook a method defined in an interface with the usual findAndHookMethod, but it returns

java.lang.IllegalArgumentException: Cannot hook interfaces: public abstract void com.angrydoughnuts.android.alarmclock.MediaListView$OnItemPickListener.onItemPick(android.net.Uri,java.lang.String)

This is my method call:

findAndHookMethod("com.angrydoughnuts.android.alarmclock.MediaListView$OnItemPickListener", lpparam.classLoader, "onItemPick", "android.net.Uri", "java.lang.String", new XC_MethodHook() {

OnItemPickListener is the interface.

Answer 1

Xposed is not able to hook abstract methods or interfaces. Only methods and constructors can be hooked.

Answer 2

You cannot hook an interface, but you can hook every implementation if needed. You can find out what classes implement an interface in Android using resources such as http://grepcode.com/search/?query=google+android&entity=project
