当我在我的 devise nexus 4 android 5.0上运行我的应用程序时，我创建了一个使用片段和minSdkVersion 10和targetSdkVersion 21创建的空白活动的 android 项目，该应用程序崩溃了，我不知道为什么。

当我从ActionBarActivity切换到 Activity 应用程序工作但我想用 ActionBarActivity创建应用程序。

和logcat给我这个错误无法启动活动ComponentInfo{com.rhanem.android.forecast.app/com.rhanem.android.forecast.app.MainActivity}：java.lang.IllegalStateException：活动已被破坏

她在 logcat 中给我这个消息

Process: com.rhanem.android.forecast.app, PID: 3644

In Manifest file specify Theme.AppCompat theme (or it's descendant) for your Activity. android:theme="Theme.AppCompat"
