My App stop working when I wanna do the AR model viewer java

[DelfianS]

Hey everyone, I'm a student working on a guitar tuner project implementing an AR guitar 3d model. So I copy the code from the AR model viewer java to my code but when I try to open the ar activity, the app just stopped working. Can anyone help me with this?

This is my AndroidManifest file

<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.RECORD_AUDIO" />
<uses-permission android:name="android.permission.CAMERA" />
<uses-feature android:glEsVersion="0x00030000" android:required="true" />

<uses-feature
    android:name="android.hardware.camera.ar"/>

<application
    android:allowBackup="true"
    android:icon="@drawable/app_logo"
    android:label="@string/app_name"
    android:roundIcon="@mipmap/ic_launcher_round"
    android:supportsRtl="true"
    android:theme="@style/Theme.GuitarTuner">

    <activity
        android:name=".MainActivityAr"
        android:exported="true"
        android:configChanges="orientation|screenSize"
        android:screenOrientation="locked"/>

    <activity
        android:name=".chordActivity"
        android:exported="true" />

    <meta-data
        android:name="com.google.ar.core"
        android:value="required" />

    <activity
        android:name=".TuneActivity"
        android:exported="true" />
    <activity
        android:name=".IntroActivity3"
        android:exported="true" />
    <activity
        android:name=".IntroActivity1"
        android:exported="true">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <activity
        android:name=".IntroActivity2"
        android:exported="true" />
</application>

And this is the layout

<androidx.fragment.app.FragmentContainerView
    android:id="@+id/arFragment"
    android:name="com.google.ar.sceneform.ux.ArFragment"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />
