» [solved] Unparsed aapt error(s)! Check the console for output

Today I wrote some codes for my Android application as usual, and I found a parsing error that says:

"Unparsed aapt error(s)! Check the console for output"

However, I didn't see any errors after checking all the files. So what is going on here? It happens when some *.out.xml files are generated before the entire project gets built for execution. How can this happen? It happens when you run the application when in a resource file.

The solution to this issue is simple: make sure you clean any post-built files before building your application for a run. To achieve this, go to Project --- Clean in the Eclipse menu and it will work again. Or, you can just delete R.java file. It will get created again and the problem is solved.

» [Tech Notes] Android Basics I - Android System Architecture

Android system architecture:

Get get the big picture of system architecture, please check out this documentation online. To sum up, there are four primary layers for the software system - Linux Kernel, Libraries and Android Runtime, Application Framework, Applications and Widgets.

This concept is essential because you need to know what layer (s) you will be dealing with when developing apps, making your own frameworks and libraries or even modifying Linux Kernel. For application development, you will not see Linux Kernel, all you can see is Application Framework and Application layers.
