包名: com.tencent.qqpimsecure

导出 Activities:

com.tencent.qqpimsecure.ui.activity.SplashActivity,

com.tencent.qqpimsecure.ui.activity.MainActivity,

com.tencent.qqpimsecure.ui.activity.TrafficMonitorActivity,

com.tencent.qqpimsecure.ui.activity.VirusScanActivity **com.tencent.permission.VIRUS_SCAN,

其中TrafficMonitorActivity存在null指针bug：
