Android Error CS0234 The type or namespace name 'Content' does not exist in the namespace

[VarakornK]

I buy Grial UI version Pro.

I've downloaded full package of Grail Solution and I've got a problem while compiling on Visual Studio for MAC OS, it said "Error CS0234: The type or namespace name 'Content' does not exist in the namespace 'VLPos.Android' (are you missing an assembly reference?) (CS0234) (VLPos.Android)". I've attached a screenhot to you.

Please help!

Hi @VarakornK,
Some questions here to try to find the cause of your issue:

• Are you using Visual Studio 2017 or 2019? Which version?
• which android sdk version do you have?

Hi @VarakornK,

Can you please try the following:

• clean solution
• close Visual Studio
• delete bin and obj folders in all your projects folders
• open again your solution in Visual Studio and rebuild.
• try running again in Android

JP

Hi,

The problem is that the Android part of the VLPos.Android namespace is clashing with the Android.Content.Res.Configuration full name.

You can fix the issue by including this using on top:

using Android.Content.Res;

And removing the fully qualification of Configuration in the method:

public override void OnConfigurationChanged(Configuration newConfig)

Or by using VLPos.Droid as your Android namespace to avoid further conflicts.

Hope this helps.
