"앱이름" keeps stopping 오류

Question

앱만들기 초보자입니다ㅜㅜ

단순하게 앱 시작하기 전 인트로랑 시작화면만 넣는것 부터 하려고 했는데

시작화면으로 넘어가질 못하네요.

코드입니다.

AndroidManifest

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.habang.projectrich">

    <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=".intro">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <activity android:name=".MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <action android:name="android.intent.action.VIEW" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>

MAIN ACTIVITY

<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@drawable/startpage"
    tools:context=".MainActivity">

    <Button
        android:id="@+id/button"
        android:layout_width="230dp"
        android:layout_height="80dp"
        android:text="돈벌기"
        android:textSize="35dp"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintHorizontal_bias="0.82"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent"
        app:layout_constraintVertical_bias="0.73" />

</android.support.constraint.ConstraintLayout>

아직 딱히 추가한 코드도 별로 없는데 왜 오류가 생기는 걸까요? 

알려주실분 계신가요. ㅜㅜ
