Q:

You want only a vertical scrollbar and no horizontal scrollbar on your page. How would you do it?

Answer

- This can be done by defining the frame with SCROLLING = auto and having content to just fit into this frame. 


- SCROLLING="yes" gets the scroll bar on both the sides, even when not needed. 


- SCROLLING="no" doesn’t get the scrollbars at all, even when they are needed.

Q:

Why cannot you run standard Java bytecode on Android?

Answer

Android uses Dalvik Virtual Machine (DVM) which requires a special bytecode. We need to convert Java class files into Dalvik Executable files using an Android tool called "dx". In normal circumstances, developers will not be using this tool directly and build tools will care for the generation of DVM compatible files.
