Fadden, It throws these exceptions only when " I tried to create any UI component like Toast message or invoking phone dialer inents etc. " It executes nicely when I just "tried to print a log message or created MediaPlayer and playing a song " .
So my conclusion is that It throws NullPointerException only when invoked code has a UI component. Note: same thing I had tried using the normal desktop java application using swing and excuted nicely with UI component also. So Is this a bug in android or some other way to do it.
