Error: unknown tag <:string> in my app
When I try to run a specific app, Gradle doesn't compile and shows this strange error. I searched for the tag in the file but such a tag doesn't exist. The exact state of the app
error: unknown tag <:string>. Message{kind=ERROR, text=error: unknown tag <:string>., sources=[C:\Users\nEW u.gradle\caches\transforms-1\files-1.1\constraint-layout-1.1.0.aar\b3e4ef6bef14a8fe09fa894d105f65d7\res\values\values.xml:3:5-61], original message=, tool name=Optional.of(AAPT)}
However, this isn't the case for other apps I built before, they run smoothly without any error. Please tell me what is the remedy. Thank you before-hand.
EDIT: Newer projects too face the same problem.
Edit 2: When I remove the implementation 'com.android.support.constraint:constraint-layout:1.1.0' at build.gradle of the app. It shows this error.

Had very similar error. As turned out the reason was related to string array. In your string.xml check if you have empty <string-array> or something like
<string-array name="array_name">
<string name="array_name_item">Some text</string>
...
</string-array>
You should update <string> tag to <item> tag like this:
<string-array name="array_name">
<item name="array_name_item">Some text</item>
...
</string-array>
Hope it solves your issue, because Android Studio error message is really confusing here.

Khrystyna Pochynokin Android Studio find the word plz ctrl+shift+f <:string> you can easily find and remove the : in string tag.

Bhupat BhedaNothing worked actually. Since the error was in some file in the .gradle folder I deleted the folder entirely to make a new one by rebuilding the project. That didn't solve the problem, again an error occurred. So, my last resort was to delete every file related to Android and reinstall everything.
