Answer 2

Most of the errors in XML happen due to the names you have given to the resources.

Images stored in the drawable folder need to be named in a proper manner. just check these things:

1. Are there any duplicate files? if so remove the duplicates. (For example "image.jpg" and "image.png" are not allowed in the same time. It will not show any errors but sometimes it will show that R.java cannot be resolved)
2. Do the filenames contains any uppercase letters? If so right click on that file->refactor->rename and rename it with all lowercase, no hyphens, and only a-z and 0-9 are allowed.

Just make sure of the above cases.

In my case the problem occurred while the default setting for Android Version in the Designer was set to 'Preview N'. Changed Android Version to '23' and the error notification went away.
Edit
And don't forget to uncheck 'Automatically Pick Best'.

Answer 5

I got the same problem with my customized theme that used Holo.Light as its parent. In grayed text Android Studio indicated that some attributes were missing. When I added these missing attributes as follows, the rendering problems went away -

    <item name="android:textEditSuggestionItemLayout"></item>
    <item name="android:textEditSuggestionContainerLayout"></item>
    <item name="android:textEditSuggestionHighlightStyle"></item>

Even though they introduced errors in my style's theme, they caused no problems in rendering the activity designs or building my app.

Answer 6

You can simply remove this error through change "App theme" and select any theme such as light. This error will be removed.
