根无法列出/数据中的文件 -- adb 领域和 superuser 领域 android 相关的问题

root cannot list files in /data

su 的权限是正确的吗？我得到了哈希提示，但我不能列出/数据中的文件（或做任何需要超级用户权限的任何东西）。我没有安装superuser.apk，因为如果擦除设备，我不想安装它，因为拨打/拒绝访问对话框弹出。 superuser.apk在解开* .img文件时，我不能做什么？

The permissions on su are correct right? I get the hash prompt, but I can't list the files in /data (or do anything that requires superuser permissions). I don't have Superuser.apk installed, I don't want to install it because of that grant/deny access dialogue that pops up if you wipe the device. What does Superuser.apk do that I can't do when I unpack the *.img files?

也许你应该安装文件管理器。我推荐氰基莫德。此外，超级用户是SU文件和应用程序之间的桥梁。 AFAIK，您无法自己创建该连接。 2013-10-09 00:27:22Z, License: CC BY-SA 3.0

如果超级用户可以，所以我也可以知道如何知道如何。文件管理器不会帮助我，我需要adb shell root访问权限超过浏览文件。 MishaP 2013-10-09 16:14:03Z, License: CC BY-SA 3.0

我需要完全root权限到adb shell来运行android shell命令，添加/删除/读取文件，然后务实地打开/关闭服务以进行测试。虽然我知道如何自动执行UI，但我需要在没有UI的情况下完成所有这些，以减少初始化设备进行测试所需的时间。并且我需要在出厂重置后维护adb和root访问权限。 MishaP 2013-10-10 01:51:01Z, License: CC BY-SA 3.0

您使用的是什么版本的Android？自4.3起刚刚拥有 Sergey Vlasov 2013-10-10 07:48:38Z, License: CC BY-SA 3.0

Perhaps you should install a file manager. I recommend CyanogenMod's. Also, SuperUser is the bridge between the su file and the application. AFAIK, you cannot create that connection yourself 2013-10-09 00:27:22Z, License: CC BY-SA 3.0

if SuperUser can, so can I. I just need to know how. File manager won't help me, I need adb shell root access for more than browsing files MishaP 2013-10-09 16:14:03Z, License: CC BY-SA 3.0

Perhaps we can help if you tell us what you want to do instead of giving us pieces at a time :) 2013-10-10 00:29:42Z, License: CC BY-SA 3.0

I need full root permissions to adb shell to run the android shell commands, add/remove/read files, and turn services on/off pragmatically for testing purposes. And although I know how to automate the UI, I need to do all of this without the UI in order to reduce the time that is required to initialize the device for testing. And I need to maintain ADB and root access after a factory reset MishaP 2013-10-10 01:51:01Z, License: CC BY-SA 3.0

What version of Android are you using? Since 4.3 just having Sergey Vlasov 2013-10-10 07:48:38Z, License: CC BY-SA 3.0

输入 su 首先。

＆gt;苏
＆gt; ls / data

确保您的设备已植根。

Enter su first.

> su
> ls /data

Make sure your device is rooted.

我这样做，我得到了哈希提示（＃），但这是关于更改的唯一事情，我有常规的用户权限，而不是超级用户权限。 MishaP 2013-10-09 22:07:36Z, License: CC BY-SA 3.0

I do, and I get the hash prompt (#) but that's about the only thing that changes, I have regular user privileges, not super user privileges MishaP 2013-10-09 22:07:36Z, License: CC BY-SA 3.0

对于某些操作，adb也必须作为root运行。
您可以通过运行 adb root ，轻松地重新启动具有root权限的adb守护程序。。
然后，您可以再次输入 adb shell ，用 su 并在您想要的地方进行导航。

当我完全相同的问题时为我工作。

其他人的补充：
某些超级用户应用程序在配置中有一个选项，以允许根权访问APPS，ADB或两者。默认值不一定允许adb根访问。

For some operations, adb must be running as root as well.
You can easily restart the adb daemon with root permission by running adb root.
Then you can enter adb shell again, switch to root with su and navigate wherever you'd like.

Worked for me when I had exactly the same problem.

Small addition for others:
Certain superuser apps have an option in configuration to allow root access to either apps, adb or both. The default is not necessarily to allow adb root access.
