How can i delete a file in /app/data

[Ahmadhashemi]

i need to delete a file for example(filename.txt) in /app/data/ folder of internal ram (not sd-card)
i know that i can use file.Delete (folder address,file address) but how i define folder name?
i test the "/data/app/" for folder address and it was wrong.
please help me
:sign0013: for my english

file.Delete(file.DirInternal,"filename.txt")

DirInternal is the Data directory of your app

thanks.
but my question is:
if your device rooted and you install root explorer when you open root explorer in first page you see some folder for ex : sd-card , app, system,...
i say how can i delete a file in this app folder!!
not in file.Direinternal.

Hi thedesolatesoul !
this code is wrong beacuse i use it and it couldn't delete that file.

What error do you get?
Is it a permissions issue or a path issue?
Check the logs.

i dont recive error.but i think path issue.
if it is permissions issue what can i do?

 

[thedesolatesoul]

Have a look into the logs to find out what the actual issue is.
The Logs tab is on the right side of the IDE.

i test my code and when i press the button with this codes:

Sub btn_rpl_Click
File.Delete("/data/app","mytext.txt")
End Sub

(without filter in Logs tab)

can i use shell command to delete this file?
when i want to go to /data/app directory this message was shown:
permission denid.

Is your device rooted?
Try connecting with adb and see the permissions in that directory using: 'ls -l'
You can also use shell commands but you will not be able to see any feedback if it was successful or not.
