Have three errors relate to expecting an element and unresolved references

[related code for error in MainActivity.kt][2]
I have tried fn+option+return(Mac IOS) for import purpose, but still not working. Same as trying invalidate caches and restart. They are not working!
I just follow the lecture which is given by the professor step by step. The version for the Android studio on my macbook is 3.5.1
Looking for help.
I also met another error. Here is the code for the AndroidManifest.xml
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.assignment3muyaozhang0882423" >

<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name=".MainActivity" >
</activity>
</application>
</manifest>
The error I met which is sync error:
ERROR: Failed to parse XML in /Users/kitty/Downloads/Assignment2MuyaoZhang0882423/app/src/main/AndroidManifest.xml

Please check out my reply on your comment too.
Click on the error of text_layout and send the relevant code.

It is LinearLayout.LayoutParams.MATCH_PARENT
the underscore is missing between MATCH and PARENT

Debugger doesn't go into MainActivity

I got strange problem with white screen and debugger not going into MainActivity. It goes into App class, but doesn't fire the onCreate in MainActivity.
However, if I start my app without debug - just run the app, or build app - it goes into MainActivity fine. I can't find anything specific in my app or any info on what it might be
here's manifest :
<?xml version="1.0" encoding="utf-8"?>

After all, and error and testing, but nothing is still displayed on the dashboard.
I do everything step by step from fabric documents.
I have this problem for a few days, and anyway I've tested it, but I still have not gotten a result and does not display anything in the fabric dashboard. ApiKey is correct and I'm sure of it.

Firebase android facebook,google,email login interface does not popup

I've watched a tutorial on YouTube about how to integrate Firebase to android applications. Registered Firebase, add my facebook and app info, and add the necessary changes to my app but somehow my main interface which should show login screens does not show up. There is no build errors.

Any help is appreciated. Thanks in advance.

Try changing startActivityForResult() to:
startActivityForResult(
AuthUI.getInstance()
.createSignInIntentBuilder()
.setProviders(Arrays.asList(
new AuthUI.IdpConfig.Builder(AuthUI.FACEBOOK_PROVIDER).build(),
new AuthUI.IdpConfig.Builder(AuthUI.EMAIL_PROVIDER).build(),
new AuthUI.IdpConfig.Builder(AuthUI.GOOGLE_PROVIDER).build()
))
.build(),
RC_SIGN_IN);
To learn more about authentication on Firebase UI library look at:
