[带有Unity和AR核心的Android Studio中的java.lang.ClassNotFoundException问题

Question

我在Android Studio中的logcat中具有以下权限错误：

我正在Unity中使用AR Core从Google构建HelloAR示例，然后将其导出到Android Studio，以便可以通过按钮启动它。直接从整体部署时，该应用程序运行良好，但从Android Studio部署时，该应用程序卡在了黑色加载屏幕上。根据以上错误，我认为它没有得到正确的许可，但是我可以肯定我拥有所有这些。请在下面查看我的Andorid清单：

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


        package="com.test2.testandroud">
        <uses-permission android:name="android.permission.CAMERA"/>

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

        <application

            android:allowBackup="true"

            android:supportsRtl="true"
            android:theme="@style/AppTheme">
            <activity android:name=".MainActivity">

                    <category android:name="android.intent.category.LAUNCHER" />
                </intent-filter>

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

            </activity>
            <activity android:name="com.test2.testandroud.MainUnityActivity" android:screenOrientation="fullSensor" android:configChanges="mcc|mnc|locale|touchscreen|keyboard|keyboardHidden|navigation|orientation|screenLayout|uiMode|screenSize|smallestScreenSize|fontScale|layoutDirection|density" android:hardwareAccelerated="false" android:process=":Unity"
                android:label="@string/app_name">

            </activity>
    </application>

    </manifest> 

任何帮助都会很棒。谢谢。
