안드로이드 스플래시 화면 에러 질문드려요

Question

스플래시 화면을 구성해서 적용해봤는데요

스플래시 화면이 뜨자마자 Splash keeps stoppings 하면서 앱이 바로 실행이 종료가되더라구요

manifest

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.administrator.splash">
    <uses-permission android:name="android.permission.INTERNET" />
    <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=".SplashActivity"
            android:screenOrientation="portrait"
            android:theme="@style/SplashTheme">
            <intent-filter>
                <action android:name="android.intent.action.VIEW" />
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>

styles.xml

<resources>

    <!-- Base application theme. -->
    <style name="SplashTheme" parent="AppTheme">
        <item name="windowActionBar">false</item>
        <item name="windowNoTitle">true</item>
        <item name="android:windowBackground">@drawable/loading</item>
    </style>

    <style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
        <!-- Customize your theme here. -->
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
        <item name="colorAccent">@color/colorAccent</item>
    </style>
</resources>

SplashActivity

import android.content.Intent;
import android.os.Bundle;
import android.support.annotation.Nullable;
import android.support.v7.app.AppCompatActivity;

public class SplashActivity extends AppCompatActivity {
    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        Intent intent = new Intent(this, MainActivity.class);
        startActivity(intent);

    }
}

splash.xml

<layer-list xmlns:android="http://schemas.android.com/apk/res/android"
    android:opacity="opaque">

    <item android:drawable="@color/colorPrimary" />
    <item
        android:id="@+id/splash_layer"
        android:top="72dp"
        android:bottom="72dp"
        android:left="72dp"
        android:right="72dp"
        android:gravity="center"
        android:drawable="@drawable/loading">
    </item>
</layer-list>

이런식으로 구성하고 메인과 액티비티메인은 그냥 원래화면으로 해두었는데

뭐가 문제인지 아시는 고수님 도와주세요..
