Unknown attributes in xml

Question

I mean the android attributes like width, height, id and ... . I did everything:

Invalidate cache
clean & rebuild project
delete .idea folder

and all the other answers that we're suggested. None worked for me. What did work was downgrading the sdk version from 27 to 26. Any clues what might have happened to my 27 sdk version?

Edit: Unknown attribute ScreenShot

You might have different SDK versions for support libraries. — Reaz Murshed, Oct 09 '18 at 06:02
Sorry I'm new here and I don't know to put the logcat in a scrolling view and I don't any crashes so I don't know if the logcat helps. — Erfan Estiri, Oct 09 '18 at 09:21
@ErfanEstiri Hello erfan and welcome to SO. Would you add your `build.gradle` dependencies too? Yes that helps. — ʍѳђઽ૯ท, Oct 09 '18 at 09:21

The codes and warnings you see are in runtime of the application. Stop the installation-run app then check your dependencies to see if there is a problem with them or not.

(Make compileSdkVersion & targetSdkVersion the same version to 27) If you're using 27 support libraries.

However, your layout doesn't seem to be fine.

Move layout_behavior to your NestedScrollView or RelativeLayout (or actually, the content below the AppBarLayout.

I added the build.gradle but it was added to the end of the logcat. As u can see both compileSdkVersion & targetSdkVersion are 27. I also moved the layout_behavior and no changes. I don't see any code completion since they're unknown. – Erfan Estiri Oct 09 '18 at 09:29
Stop the app installation. Then reinvalidate-cashes restart. This should help. Also, in your layout there were few issues which I’ve explained. – ʍѳђઽ૯ท Oct 09 '18 at 09:33
A lot of problems are occurring after updating AS to 3.2v. – Erfan Estiri Oct 09 '18 at 09:33
It’s acutally might happens because of AndroidX migration or the new support library 28.0.0. You can also use 28.0.0 to see if those errors gone. Reinvalidate caches might help too. – ʍѳђઽ૯ท Oct 09 '18 at 09:34
Reinvalidating the caches didn't work until I deleted my sdk and downloaded it again. Now the previous issue is fixed but something new has occured. – Erfan Estiri Oct 09 '18 at 09:39
Posted a new answer including both problems' screenshots. – Erfan Estiri Oct 09 '18 at 09:44
Remove it (tools:context..) and it will work fine. About that java issue, it seems like it couldn’t find some java libraries - annotiotions. Use attach annotioations. – ʍѳђઽ૯ท Oct 09 '18 at 09:46
Won't removing that cause in problems in terms of connecting the xml layout to the java class? And also the attach annotations doesn't seem to do anything and the popup won't go away. – Erfan Estiri Oct 09 '18 at 09:50
You won’t need that tools:context. However, check this link for that anothet issue: https://stackoverflow.com/questions/50740240/no-idea-annotations-attached-to-the-jdk-1-8-c-some-issues-will-not-be-fo – ʍѳђઽ૯ท Oct 09 '18 at 09:51
Thanks @Mohsen for putting the time. The second answer in the link provided seemed to make that popup go away but I still think I need to reinstall AS and downgrade to 3.1.2 since 3.2 seems really buggy. +1rep. – Erfan Estiri Oct 09 '18 at 10:00
If you want to use support libraries yes, Android studio v3.2 is better for AndroidX migration. Glad to help – ʍѳђઽ૯ท Oct 09 '18 at 10:18

Issue is not your sdk version

Add this in your build.Gradle

implementation 'com.android.support:appcompat-v7:27.1.1'

your Exception is

Rejecting re-init on previously-failed class java.lang.Class<uJ>: java.lang.NoClassDefFoundError: Failed resolution of: Landroid/webkit/TracingController;

and

Caused by: java.lang.ClassNotFoundException: Didn't find class "android.webkit.TracingController" on path: DexPathList[[zip file "/data/app/com.android.chrome-1/base.apk"],nativeLibraryDirectories=[/data/app/com.android.chrome-1/lib/arm, /data/app/com.android.chrome-1/base.apk!/lib/armeabi-v7a, /system/lib, /vendor/lib]]

or post your code too. for better help.
