原因：

无法引动Unable to instantiate activity ，原因是 没有找到相应的类。

解决：

原来是我的AndroidManifest.xml中配置activity是名称配置错了，修改即可。

<activity
android:name="com.zjdzssbd.s360.XXkapai" -- 错了 android:configChanges="orientation|screenSize|smallestScreenSize" android:label="@string/app_name" android:screenOrientation="landscape" android:theme="@android:style/Theme.NoTitleBar.Fullscreen" > <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity>
