Question

Do Android have any way to instantiate objects without calling any of its constructors?

In Java, Sun have sun.reflect.ReflectionFactory.getReflectionFactory().newConstructorForSerialization(), in .Net we have System.Runtime.Serialization.FormatterServices.GetUninitializedObject() but I was not able to find anything like that in the Android platform.

Answer 1

After looking into Android source code we found a way to achieve this by using ObjectInputStream#newInstance() static method.

private Object newInstanceSkippingConstructor(final Class clazz) throws SecurityException, NoSuchMethodException, IllegalArgumentException, IllegalAccessException,     InvocationTargetException {

    Method newInstance = ObjectInputStream.class.getDeclaredMethod("newInstance", Class.class, Class.class);
    newInstance.setAccessible(true);
    return newInstance.invoke(null, clazz, Object.class);

}
