Why cant i sync my project in Android Studio? - android

I wanted to learn how to make android apps and downloaded android studio.
But when I made my first project and it was trying to sync an error came. This is what it said: A problem occurred configuring project ':app'.
When i went to Android Manifest most of it was red. Does someone know what to do?
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.oliver.mycart">
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:abel="#string/app_name"
android:roundIcon="#mipmap/ic_launcher_round"
android:supportsRtl="true"

Android Studio 4.0.1, Gradle, and React Native: AndroidManifest.XML not found when it exists

INTRO
Greetings, all!
My Android Studio 4.0.1 project refused to build due to not being able to find an AndroidManifest.xml file that's in /main/ where it should be, according to the documentation. Mass replacing the occurrences of "api" with "implementation" or vice versa hasn't helped.
Thus, what other information do you want for clarification, and what should change to ensure this works?
Thankee!

Every time when i open class teacher's project to my system it shows this error.Error running app: Default activity not found

I'm a beginner in Android.
Every time when I open class teacher's project to my system it shows this error.
Error running app: Default activity not found.
What should I do to match the same project as my teacher's?
I've tried many solutions.
My Manifest file is
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.assigncheckbox">
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:roundIcon="#mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="#style/AppTheme">
<activity android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>

maybe it happen because you didn't add this activity to your AndroidManifest.xml
<activity
android:name=".yourActivity"
/>

It was causing the error

MainActivity unresolved class error with android studio

Im taking the udacity coarse and for some reason android studio wont recognize my MainActivity class. Ive tried cleaning the project, rebuilding and making sure that the names were correct but nothing has solved my problem.
Android Manifest code:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="androidedx.example.activitylifecycle">
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:roundIcon="#mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="#style/AppTheme">
<activity android:name=".Activity1"></activity>
<activity android:name=".Activity2" />
<activity android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>

Found the problem, this package name within the code I had to paste
package com.example.android.cookies;
Im not sure why specifically this caused the problem but atleast I solved it.

Android Studio: App Installs But Doesn't Open Android 5.0

I've been trying to make an app. I've finished it with no errors, but when I install it on my device I can't open it.
I've searched for the solution on here, but nothing has helped. Most people post their AndroidManifest, so here it is.
<?xml version="1.0" encoding="utf-8"?>
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:roundIcon="#mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="#style/AppTheme"></application>
<activity android:name="Main">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
Any help is much appreciated. Thanks!
