Question

当我尝试在模拟器上运行我的应用程序.splashActivity类没有被直接调用LoginActivity被调用，而当我在我的设备中通过usb运行它会抛出以下异常，

这是一个奇怪的行为，当我删除我的LoginActivity时调用了splashActivity类，并且由于找不到loginactivity而关闭了应用程序，当我恢复启动时，MainActivity一切正常

[2012-11-22 16:59:57 - medeclinicv2] ActivityManager: Starting: Intent { act=android.intent.action.MAIN cat=[android.intent.category.LAUNCHER] cmp=com.kredence.medeclinicv2/.LoginActivity }

[2012-11-22 16:59:57 - medeclinicv2] ActivityManager: java.lang.SecurityException: Permission Denial: starting Intent { act=android.intent.action.MAIN cat=[android.intent.category.LAUNCHER] flg=0x10000000 cmp=com.kredence.medeclinicv2/.LoginActivity } from null (pid=5929, uid=2000) requires null

这是我的Manifiest代码，我已经清理了我的项目

查看您的Android清单代码。

通常，java.lang.SecurityException是因为您可以输入两个指向同一活动的条目。删除第二个，你应该很高兴。
