Just as we have the java class library (JCL) we also have the android class library (ACL)
As you already know that without the experience or the background of java, programming in android will be difficult.

3. android.widget
4. android.view
5. android.graphic
Learning this 5 class library can make you a good programmer. But in this tutorial and later tutorials we shall consider all the class library.
By the time of writing this we have 41 android class library. Let us take a look at the java class library
import java.awt
import java.beans
import java.io
import java.lang
import java.math
import java.net
import java.nio
import java.security
import java.sql
import java.text
import java.util
By the time of writing this, we have 11 java class library. To put every thing to your understanding let us take the history of android.
