主要错误：

02-03 15:52:46.405: ERROR/CrashHandler(736): Unable to start receiver com.taobao.iphone4s.BootBroadcastReceiver: android.content.ActivityNotFoundException: Unable to find explicit activity class {com.taobao.iphone4s/com.taobao.iphone4s.Start}; have you declared this activity in your AndroidManifest.xml?

原因：AndroidManifest.xml未添加对应Activity配置。

解决办法：在AndroidManifest.xml添加对应Activity配置内容。

<activity android:name=".Start" android:label="@string/app_name" android:theme="@android:style/Theme.Dialog" android:screenOrientation="user" android:configChanges="orientation|keyboardHidden"> <intent-filter> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity>
