追踪Code,在/frameworks/base/services/core/java/com/android/server/pm/PackageManagerService.java中找到抛出异常的处理位置：

if (mFrozenPackages.contains(packageName)) {throw new SecurityException("Package " + packageName + " is currently frozen!");}

问题产生的原因是：

这是因为强制清除应用程序数据可能会由于缺少文件/数据库和应用程序崩溃而导致异常行为。通常用户还需要重新启动应用程序，以确保所有应用程序数据都可以重新设置。
这取决于应用程序设计是否考虑到缓存文件异常，如果应用程序正在运行但缓存文件已清除，则是否重建文件。这个一般是应用程序需要考虑的问题。
