No empty constructor when create a service

Question

I am struggling with this error:

08-08 11:42:53.179: E/AndroidRuntime(20288): Caused by: java.lang.InstantiationException: can\'t instantiate class co

Answer 1

If you have your Service declared as an Inner Class / Nested Class, you also need to make the class static

Without that you´ll get the error even if your constructor is correct

Explanation

The reason for that is, you can only instantiate inner classes in the context of the outer class, so you would need to create an instance of the outer class first.

Declaring your inner class static makes it independent from its outer class
