After a whole night spent in test (without any luck) I need some support with my interface. I'm working directly on the Android frameworks and I created a class that works as a Binder with a WeakHashMap to control the callbacks.
Here is the code:
MyCallback:
public interface MyCallback {
public void fire();
}
MyBinder:
public static WeakHashMap<String, MyCallback> mCallbacks =
new WeakHashMap<String, MyCallback>();
public static void setup(MyCallback callback) {
if(mCallbacks.get(callback.getClass().getName()) == null) {
mCallbacks.put(callback.getClass().getName(), callback);
}
}
public static void letsgo() {
Log.d("size", " " + mCallbacks.size()); // IMPORTANT
for (MyCallback cb : mCallbacks.values()) {
cb.fire();
}
}
These 2 classes are written into frameworks so I created 2 test applications with a simple class that implements my interface:
public class FirstApp implements MyCallback {
public FirstApp() {
MyBinder.setup(this);
}
@Override
public void fire() {
Log.d("app1", "fired");
}
}
public class SecondApp implements MyCallback {
public SecondApp() {
MyBinder.setup(this);
}
@Override
public void fire() {
Log.d("app2", "fired");
}
}
Ok at this point I made another class (all these 3 classes, so the 2 that implements the interface and the following one are written into different packages)
In this third class i just call: MyBinder.letsgo();
The issue I'm facing, and that I'm trying to solve since... 8/9 hours is that: If i run letsgo() on the third pack the logs shown 0 for the callbacks WeakHashMap size. if i run letsgo() on the second package it works but it only fires the callback in the same package. the same if i run it on the first package.
I tried also with HashMap instead of WeakHashMap since i red that objects must be referenced but without any luck. I wonder if someone can help me and let me go sleep :D Thanks!
