The same issue, with
B4X:
Sub Get_Scr As Bitmap
' Take a screenshot.
Dim su As SuShell
su.Execute("/system/bin/screencap -p " & File.DirRootExternal & "/img.png").WaitForCompletion

Dim bmp As Bitmap
bmp.Initialize(File.DirRootExternal, "img.png")
Return bmp
End Sub
Problem is only if to shoot not my app activity.
But http://www.basic4ppc.com/forum/basi...nning-shell-commands-superuser.html#post39820 this SU script - works OK !

Can we use this library to turn on gps. Because erel said that it needs to root a device so we can turn on gps programically.

Tnx...

Please could you tell me how to use the SuperUser Library to solve my following simple Problem.
I have a picture in /sdcard/DCIM/Camera an want to copy it to my external SD Card /storage/7831-5E32.
I get a Permission Denied Error despite I have rooted my Galaxy S7.
There are no problems in the case of copying in the opposite direction.

Greetings
Horst Leistner


Manifest:

AddPermission("android.permission.WRITE_SETTINGS")
AddPermission("android.permission.ACCESS_SUPERUSER")


Sub Activity_Create(FirstTime As Boolean)
'Do not forget to load the layout file created with the visual designer. For example:
Activity.LoadLayout("Test")
Dim source,dest,filename As String
source = "/sdcard/DCIM/Camera"
dest = "/storage/7831-5E32"
filename = "2016.12.13_16.21.51.jpg"
End Sub

ERROR
java.io.FileNotFoundException: /storage/7831-5E32/2016.12.13_16.21.51.jpg: open failed: EACCES (Permission denied)

Inserting "android.permission.write_external_storage" makes no difference, maybe because "/storage/7831-5E32" is not the same as "external storage"
DirRootExternal = /storage/emulated/0
DirDefaultExternal = /storage/emulated/0/Android/data/lei.TstCopy2/files

Hi. I think in Samsung devices you must change the XML file with the access permisions to write the SD Card. It's not only give Root permisions to your app with this library. Look at XDA web for XML file name to change.

Thanks.
I know this is a old thread but was struggling with this for a long time also.
For me the fix was to put ' & exit ' at the end of the command string
Thx
