Android棉花糖密钥库安全例外

我正在尝试实现类似的功能。代码使用IPC，调用mRemote.transact时引发异常（IKeystoreService.java第54行）

这在棉花糖之前的Android版本（API 23）上运行良好。我知道自那以后权限模型发生了变化

例外情况是：

java.lang.RuntimeException: Unable to start activity ComponentInfo{com.example/com.example.activity.MainActivity}: java.lang.SecurityException

运行时是否需要检查特定的权限？还是这完全是另一个问题

你有解决办法吗？现在我面临同样的问题。如果你有解决办法，请告诉我。
