Android Alertdialog in AppCompatActivity

Question

Als ich bin mit Alertdialog in ECLIPSE die folgenden Import

import android.app.AlertDialog; 
import android.support.v7.app.AppCompatActivity; 

Meine Anwendung baut aber es ist nicht der Ansicht, ich will. Ich möchte

verwenden

import android.support.v7.app.AlertDialog; 
import android.support.v7.app.AppCompatActivity; 

Aber nach der Installation der Apk stürzt die Anwendung ab. Was mache ich falsch?
