The Android set-up for Tier 2 is stupidly complicated. Luckily once you have it set up the build process is pretty straightforward.
I'll assume you've set-up Eclipse in line with the instructions and added your C++ files, media etc.
Quote: "And I already found a file inside each template called "HardCodedCompileScript.bat". It works, but I don't know what does it do... Cannot find any .apk file after that."
That batch file just compiles the code.
After that check the log.txt file to see if there are any problems. If everything is ok then next you need to build the project.
In Eclipse select Project => Clean and in the new dialogue select the following options:
* Clean Projects Selected Below
* Start a build immediately
* Build only the selected projects
And finally make sure just your game/project has a tick next to it
When you select ok it will build your project. It's very quick.
Finally if you need an APK file then select File => Export and pick Export Android Application in the Android folder.
If you haven't one already then you will need to create a keystore to sign your APK but that's pretty straight forward.
Good luck!
