Error

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.

Menu-->Build-->Clean Project[![Menu-->Invalidate Cache and restart

Clean Project[![Menu-->Invalidate Cache and restart

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"
             />
