Main goal is to override Android system class (Activity, View etc) with my own implementation.
http://android-developers.blogspot.com/2011/07/custom-class-loading-in-dalvik.html
ClassLoader for custom class loading is implemented, loading non-system class (custom class) works.
But when I try to load Activity with my implementation - it doesn't load, because ClassLoader already has this class in its cache:
/**
* Returns the class with the specified name if it has already been loaded
* by the virtual machine or {@code null} if it has not yet been loaded.
*
* @param className
* the name of the class to look for.
* @return the {@code Class} object or {@code null} if the requested class
* has not been loaded.
*/
protected final Class<?> findLoadedClass(String className) {
ClassLoader loader;
if (this == BootClassLoader.getInstance())
loader = null;
else
loader = this;
return VMClassLoader.findLoadedClass(loader, className);
}
How can I change class loader to inject my own class instead of system?
