Android Question Problem with file of configuration

[Heppy]

Hi.

He does not read me a text file when he reboots the phone. I give example. I have Android 7.1.1

Don't open layout in startboot

Sub LeerIP
    Dim List1 As List
    If File.Exists(File.DirDefaultExternal, "HeppyMPD.txt") = False Then
        List1.Initialize
        List1.Add("192.168.1.17")
        List1.Add("8000")
        File.WriteList(File.DirDefaultExternal, "HeppyMPD.txt", List1)
        MPD.IP="192.168.1.17"
        MPD.Puerto=8000
        EditText1.Text="192.168.1.17"
        EditText2.Text="8000"
    Else
        List1.Initialize
        List1 = File.ReadList(File.DirDefaultExternal, "HeppyMPD.txt")
        MPD.IP=List1.Get(0)
        MPD.Puerto=List1.Get(1)
        EditText1.Text=List1.Get(0)
        EditText2.Text=List1.Get(1)
        Log("Leyendo")
    End If
End Sub

Y el manifest:

'This code will be applied to the manifest file during compilation.
'You do not need to modify it in most cases.
'See this link for for more information: https://www.b4x.com/forum/showthread.php?p=78136
AddManifestText(
<uses-sdk android:minSdkVersion="5" android:targetSdkVersion="26"/>
<supports-screens android:largeScreens="true"
    android:normalScreens="true"
    android:smallScreens="true"
    android:anyDensity="true"/>)
SetApplicationAttribute(android:icon, "@drawable/icon")
SetApplicationAttribute(android:label, "$LABEL$")
CreateResourceFromFile(Macro, Themes.DarkTheme)
'End of default text.

Since you're targeting API 26 you should ask for runtime perimissions.

Thanks for the reply

Not really.

Use RuntimePermissions.GetSafeDirDefaultExternal or File.DirInternal. Make sure to watch the video tutorial.

Ok, my reply was too short but it was because I linked the proper thread where all the infos could be read by the OP.
What do you find wrong with it? Should I had to refer to API23+ instead of 26, B48 and Google new policies?
I am asking because I like to know what it should be the right way to reply, short of "watvh the video". TIA

ps: personally I use GetSafeDirDefaultExternal or DirInternal so I don't experience any problem. At least so far..
