Question

Android Studio 3.0 has a feature about Device-File-Explorer which can help us view files on Android device. it's exciting for non-rooted devices.I know Android Studio actually uses such as adb exec-out run-as command to extract files.

Here is a capture:

As you see, there is a column called Permissions . **I want to know what role of Device-File-Explorer .

One more, if we have write permission can we write something to a file such as SharedPreference file?

EDIT

In fact I want to know Device-File-Explorer 's permission such as the owner or group or others.

Answer 1

The Device File Explorer allows you to view, copy, and delete files on an Android device. This is useful when examining files that are created by your app or if you want to transfer files to and from a device.

Note: Most device data is not visible unless you are using a rooted device or an emulator with a standard Android (AOSP) system image (not one of the Google APIs or Google Play system images). And when using a connected device, be sure you enable USB debugging.

if we have write permission can we write something to a file such as SharedPreference file?

No

check this descriptions

Example:

drwxrw—x means:

File type: d (Directory),

Owner permission : rwx (Read/Write/Execute),

Group permission : rwx (Read/Write/Execute),

World permission : --x (Only Execute), cannot read the internal data of the directory, or write into it.
