Answer 1

After updating to SDK Tools to rev. 22 for the first time, you may need to relaunch Android SDK Manager again and install a new item: Android SDK Build-tools.

No generated R.java file in my project

Answer 2

Well there is multiple possibilities but it seems that you are trying to run an application with a certain api level with something that doesn't support it. This is my guess, what was the minimum api level that you chose when setting the application up and are you trying to test on an emulator or physical device? Also go to your sdk manager option and tell me what you have installed.
