Using Java Reflection with Eclipse ADT to Access Internal/Hidden API classes.
Purpose
We present a way to access all the Internal and Hidden Java packages/classes
in the AOS. To do this we need to both repackage the Android.jar and hack the
Eclipse ADT plugin, to allow using these internal packages.

==================================================
Do NOT post general questions/requests on how to
do this or that, they will not be answered here.
DO post if you have additional tricks, hacks or
information that can help/benefit this tutorial.
==================================================
Background
There are two reasons one cannot use internal packages. One reason is that, if
you're using Eclipse as your development platform, those packages are
internally blocked in the Eclipse ADT plugin. Second reason is that the normal
development android.jar runtime does not contain those *.class files that
belong to the internal packages.
"There is no easy way to use com.android.internal package (internal API) or
anything marked with @hide attribute (hidden API) without using reflection.
That’s because android.jar file does not contain classes from internal and
hidden API and because of this nobody can reference those classes in compile
time."
Thus we need to first restore the "original" android.jar which will allow us
to use internal and hidden APIs. But the runtime equivalent of Android SDK’s
android.jar file is framework.jar. This file is located in the
/system/framework/ directory of your device. We will extract and use this for
our pleasure.
The general procedure:
A) Grab the "full" framwork.jar from your device
B) extract the class files
C) add them to "full" android.jar ??
D) Hack the Eclipse ADT plugin jar.
Finally, NOTHING would have been possible without the excellent step-by-step
instructions on the devmaze-blog by senior Android developer Ievgenii Nazaruk
(aka. "inazaruk"). THANK YOU Ievgenii!
