What is Activity base class: java.lang.Object or android.content.Context? The class overview is not clear to me (see the image please). <img src="https://i.stack.imgur.com/yEiMl.png" alt="">

In Java every class has an <code>Object</code> as a superclass (You can also have more information here). <code>Context</code> is a Java class hence it has <code>Object</code> at the root of its inheritance tree hierarchy. <code>Context</code> is a class that holds information about an application environment as described in the official documentation, and <code>Activity</code> has it in its inheritance tree.

Context is the base class for Activity.
