At the step of Running your app I cannot run app from Eclipse. The command line way does not work.After several tries, it seems the RHEL does not have an updated Ant package (currently it is 1.7 but I need 1.8). Give up.

Just uncompress adt-bundle-linux-xxx.zip and run the file <eclipse>. It just works!

Where to find the apk files on devices
See here. It is located under /data/app/.
Failed to install HelloWorld.apk on device (null) Error
Solution: Try changing the ADB connection timeout. I think it defaults that to 5000ms and I changed mine to 10000ms to get rid of that problem. If you are in Eclipse, you can do this by going through Window -> Preferences and then it is in DDMS under Android.
Build without running an application
Building vs running: Building will just generate apk file but running will install the app to the device.
See here. In Eclipse menu, Windows -> Preferences. From this Preferences window: Android -> Build. Now uncheck "Skip packaging and dexing until export or launch. (Speeds up automatic builds on file save.)". From now on, as long as we save any changes in source files, the apk file will be recreated.
