Hi, All

I'm making Appcompat Webview app.
Now it needs to use "CreateResourceFromFile(Macro, Core.NetworkClearText)" in the manifest editor.
But when i have added it - the app cannot be compiled. Without it complilation was and is OK.
Why ?

Note that the spoiler buttons only make it more difficult to read your post.

I don't see any relation between CreateResourceFromFile(Macro, Core.NetworkClearText) and the error you posted.
Maybe you removed the AppCompat theme?

Do you get a similar error if you add this line to this example: https://www.b4x.com/android/forum/threads/79896/#content ?

Hmmm, solved. I deleted "Objects" folder and it was re-compiled OK.
Strange, but solved.
