Issues with R.java after installed ADT 8.0.1

When I installed a new version of ADT plugin, Eclipse doesn't allow me to run my project. There is a message in Problems开发者_如何转开发: "Error executing aapt. Please check aapt is present at /media/DATA/Program Files/android-sdk-linux_x86/platform-tools/aapt", though it's there! And also I have got such message in Console: R.java was modified manually! Reverting to generated version! But I didn't delete it.

I have installed Android SDK Tools r8 to be compatible with ADT 8.0.1.

Can anybody explain me what can I missed in the configuration of my environment? Thank you for help.

Delete existing R.java file from your package, then clean your project (in projects menu there is option to clean) in eclipse, rebuild it. It may solve your problem.
