Android Question Android 6.0 Android Permissions

[BitsAndBytes]

I have an app on android 6.01 and when i uninstall it , it crashes and i must go to Apps/Storage and enable the "Storage Permision". How i can show the user a message to give android permission on Storage, each time he uninstall my app ?

Runtime Permissions (Android 6.0+ Permissions)

I still cant figure out, i must search for an example somewhere

Set the targetSdkVersion to 19 if you don't want to handle runtime permissions.

I allready set it but before i upload my app, PlayStore appeared a message which said "You are targeting users with older devices <API19 and this may be a problem" so i change it to 24API

My Code Is So Simple

Sub Globals
    Private rp As RuntimePermissions
    Private boolNeedAccessPermision As Boolean
End Sub

Sub Activity_Create(FirstTime As Boolean)
   If FirstTime = True Then
        Activity.LoadLayout("main")
        File.Copy(File.DirAssets, "user_settings.txt", File.DirInternal, "user_settings.txt")
   End if
End sub

This code doesn't require any permission.

java.io.FileNotFoundException: /storage/emulated/0/user.txt:

this is another file than in your code above.... AND it is not the DirInternal....
