安卓dumpsys权限拒绝 [英] android dumpsys permission denial

问题描述

我有我的地方创建一个进程，并调用 dumpsys telephony.registry 命令来获得移动网络状态信息的应用程序。

 的String [] CMDS = {dumpsys telephony.registry};
。进程p =调用Runtime.getRuntime（）EXEC（CMDS [0] +\ N）;
 

和在那之后我解析命令的结果。对于LS或其他命令，它工作正常。对于dupmsys我得到权限拒绝：不能从PID-953自卸telephony.registry，UID = 10090 。我得到了同样的错误结果 dumpsys功率或其它dumpsys命令。

我在Android清单设置DUMP权限 android.permission.DUMP 象建议的这里

我想，我这样做是正确的，因为Android提供了此功能这里

我也做了一步描述这里强制日食让我给在清单中我的应用程序DUMP许可。

当我执行dumpsys命令我总是得到相同的结果。

权限拒绝：不能从转储telephony.registry PID-953，UID = 10090

我是不是做错了什么？为什么Android操作系统仍然拒绝我进入转储服务？

PS我已经设置分API 8，我在测试设备​​上运行的应用程序（ICS） API 15

解决方案

  

为什么Android操作系统仍然拒绝我进入转储服务？

|系统|发展签署（或 signatureOrSystem 使用的ProtectionLevel =：

安卓由于权限被标记为旧的语法）在Android 2.3+，因此不能用普通的Andr​​oid SDK应用程序举行。

I have an application where I create a process and call the dumpsys telephony.registry command to get information about the mobile network status.

String[] cmds={"dumpsys telephony.registry"};
Process p = Runtime.getRuntime().exec(cmds [0]+"\n");

and then after that I parse the result of the command. For "ls" or other commands it works fine. For dupmsys I get Permission Denial: can't dump telephony.registry from pid-953, uid=10090. I get the same error results for dumpsys power or other dumpsys commands.

I have set DUMP permissions android.permission.DUMP in the android Manifest like suggested here

I think that I am doing this right since Android offers this feature here

I have also done the step described here to force eclipse to allow me to give my application DUMP permission in the manifest.

When I execute the dumpsys command I always get the same result

Permission Denial: can't dump telephony.registry from pid-953, uid=10090

Am I doing something wrong? Why does android OS still deny me access to the dump service ?

PS I have set min API 8 and I am testing the application on device running (ICS) API 15

解决方案

Why does android OS still deny me access to the dump service ?

Because that permission is flagged as android:protectionLevel="signature|system|development" (or signatureOrSystem using the old syntax) on Android 2.3+, and therefore cannot be held by ordinary Android SDK applications.
