whenever you see
B4X:
File.DirRootExternal
you immediatly know it is broken.

yes, i done all what you said,
( If PhoneVer.SdkVersion >=23 Then
rp.CheckAndRequest(rp.PERMISSION_WRITE_EXTERNAL_STORAGE)
Wait For Activity_PermissionResult (Permission As String, Result As Boolean)
xui.MsgboxAsync(Result,"Result:")
End If)

manifest
<uses-sdk android:minSdkVersion="14" android:targetSdkVersion="30"
android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

but it doesnt work , always occurs <Permission denied>, what should i do ?

it seems to have to set phone's Permission to accece files, isn't it?
check the link i posted above. If your app is supposed to be on playstore then you have to use targetsdk 33.
if not then you can use targetsdk 28 like @agraham suggested.
