更改DDMS文件权限（安卓） [英] Change file permissions in DDMS (Android)

问题描述

我想测试我的应用程序的行为，当它不能访问某些文件由于缺少权限。

I'm trying to test the behavior of my application when it cannot access some files due to missing permissions.

是否有可能改变对DDMS透视图使用FileExplorer Android仿真器的文件/文件夹的权限？

Is it possible to change file/folder permissions on an android emulator using FileExplorer in DDMS perspective?

推荐答案

要更改权限在模拟器，你需要使用从您的Adroid-SDK平台亚行外壳命令-tools。在Android的外壳，你可以输入命令苏来获得root权限。现在你可以看到和更改的权限与正常的Unix命令搭配chmod

To change permissions in the emulator you need to use the adb shell command from your adroid-sdk platform-tools. In the android shell you can enter the command su to get root access. Now you can see and change the permissions with the normal unix commands chmod

注意，在安卓系统文件夹中安装只读的。你将不得不REMOUT这本教程之后读 - 写：

Note, that the system folder in Android is mounted read-only. You would have to remout it read-write after this tutorial:

小心反正只使用可写的文件系统，如 /数据或 SD卡为您的应用程序数据，因为使用受限制文件夹可以在生产环境的负面影响！

Be careful in anyway to use only writable filesystems like /data or sdcardfor your application data since using restricted folders can have negative side effects in a productive environment!
