Android java.lang.classnotfound异常

我有一个没有错误的项目，但在运行时应用程序崩溃

日志：

android.support.v7.app.ActionBarActivityDelegate.getDrawerToggleDelegate
03-05 22:42:23.982  29908-29908/ly.priv.mobile E/dalvikvm﹕ Could not find class 'android.support.v7.app.ActionBarActivityDelegate$ActionBarDrawableToggleImpl', referenced from method android.support.v7.app.ActionBarActivityDelegate.getV7DrawerToggleDelegate

---

通过项目结构，我已经在依赖项中包含了

androidcompatv7

。但是错误仍然存在。

这是我的登录活动，我按下按钮转到下一页main activity.java，它的xml包含android support v7的依赖项

------activity_main.xml----
