este é meu strings.xml

 <resources>
 <string name="alert_internet">out</string>
 </resources>

Eu estou tentando chamar essa string na minha atividade principal, como abaixo:

 final String net = getString(R.string.alert_internet);

Eu também verifiquei meu arquivo R.java também, o int de 'alert_internet' existe. Mas, por alguma razão, sempre que eu lanço o aplicativo, ele cai no chão. O que estou fazendo errado tentando obter uma string simples?

este é meu log.cat
