'Android - Error:String types not allowed (at 'imageViewScramble' with value '')

I'm really having trouble with this one, I tried searching on the internet but didn't find anything similar.

When I try to build my app, it gives my this error

C:\Users\name\AndroidStudioProjects\project\app\build\intermediates\res\merged\debug\values\values.xml

Error:(703, 69) String types not allowed (at 'imageViewScramble' with value ''). Error:(703, 69) String types not allowed (at 'imageViewScramble' with value ''). Error:Execution failed for task ':app:processDebugResources'.

com.android.ide.common.process.ProcessException: Failed to execute aapt.

When i jump to source it points me at this:

<style name="Base.TextAppearance.AppCompat.SearchResult" parent="">
    <item name="android:textStyle">normal</item>
    <item name="android:textColor">?android:textColorPrimary</item>
    <item name="android:textColorHint">?android:textColorHint</item>
</style>

The strange thing is, that imageViewScramble isn't even in my activity_main.xml file now that I removed it. I tried adding a drawable resource to this ImageView, so that could be the problem.

Here is my XML file:

Also, it gives me another error: Can't resolve symbol "R".

Solution 1:[1]

I fix a similar issue: searching (CTRL + SHIFT + F) for the literal value that is mentioned in the message eg: 'imageViewScramble'.

In the result I went to the dimens.xml file where was located the match and I found an inconsistency in the value.

Eg: 5dp 5dp

So replacing the line with the mentioned by 5dp

Fix the issue.

Thanks for read.

Solution 2:[2]

for fixing this error goto res/value then delete the dimens.xml . it worked for me
