在 Android Studio 中打开 Unity 项目时找不到资源异常

Question

由于谷歌警告我们提供对 64 位架构的支持，我正在将我现有的 Unity 项目从Unity 5.6.6f版本迁移到Unity 2018.4.1f

运行我的项目应用程序时崩溃并显示日志，

我已经完成的步骤

我在Unity 2018.4.1f中新建了一个项目，将脚本后端配置改为IL2CPP以支持64位架构。

请看我下面的配置。

我已将 Unity 中的包名称更改为我的 Android 应用程序包名称并导出了构建。

导出后，我粘贴了 Library 文件夹、Asset 文件夹和 JniLibs 文件夹内容（这是我从导出的 Unity Android 项目中获得的））到我的 Android 项目各自的文件夹中。

我在 Android Studio 项目中的 UnityActivity 文件，

package com.example.myapplication;

import android.app.Activity;
import android.content.Intent;
import android.content.res.Configuration;
import android.graphics.PixelFormat;
import android.os.Bundle;
import android.view.KeyEvent;
import android.view.MotionEvent;
import android.view.Window;
import android.widget.FrameLayout;

import com.unity3d.player.UnityPlayer;

public class UnityActivity extends Activity {

    protected static UnityPlayer mUnityPlayer; // don't change the name of UnityPlayer.currentActivity variable; referenced from native code

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        super.onCreate(savedInstanceState);

        getWindow().setFormat(PixelFormat.RGBX_8888); // <--- UnityPlayer.currentActivity makes xperia play happy
        mUnityPlayer = new UnityPlayer(this);

        setContentView(mUnityPlayer);

        FrameLayout cameraLayout = findViewById(R.id.unity_player_layout);
        cameraLayout.addView(mUnityPlayer.getView());
        mUnityPlayer.requestFocus();

    }

    @Override
    protected void onNewIntent(Intent intent) {
        setIntent(intent);
    }

    // Quit Unity
    @Override
    protected void onDestroy() {
        if (mUnityPlayer != null) {
            mUnityPlayer.quit();
        }
        super.onDestroy();
    }

    // Pause Unity
    @Override
    protected void onPause() {
        super.onPause();
        System.out.println("OnPause called");
        mUnityPlayer.pause();
    }

    // Resume Unity
    @Override
    protected void onResume() {
        super.onResume();
        System.out.println("OnResume called");
        mUnityPlayer.resume();
    }

    @Override
    protected void onStop() {
        super.onStop();
        System.out.println("Onstop called");
    }

    // Low Memory Unity
    @Override
    public void onLowMemory() {
        super.onLowMemory();
        mUnityPlayer.lowMemory();
    }

    // Trim Memory Unity
    @Override
    public void onTrimMemory(int level) {
        super.onTrimMemory(level);
        if (level == TRIM_MEMORY_RUNNING_CRITICAL) {
            mUnityPlayer.lowMemory();
        }
    }

    // UnityPlayer.currentActivity ensures the layout will be correct.
    @Override
    public void onConfigurationChanged(Configuration newConfig) {
        super.onConfigurationChanged(newConfig);
        mUnityPlayer.configurationChanged(newConfig);
    }

    // Notify Unity of the focus change.
    @Override
    public void onWindowFocusChanged(boolean hasFocus) {
        super.onWindowFocusChanged(hasFocus);
        mUnityPlayer.windowFocusChanged(hasFocus);
    }

    // For some reason the multiple keyevent type is not supported by the ndk.
    // Force event injection by overriding dispatchKeyEvent().
    @Override
    public boolean dispatchKeyEvent(KeyEvent event) {
        if (event.getAction() == KeyEvent.ACTION_MULTIPLE)
            return mUnityPlayer.injectEvent(event);
        return super.dispatchKeyEvent(event);
    }

    // Pass any events not handled by (unfocused) views straight to UnityPlayer
    @Override
    public boolean onKeyUp(int keyCode, KeyEvent event) {
        return mUnityPlayer.injectEvent(event);
    }

    @Override
    public boolean onTouchEvent(MotionEvent event) {
        return mUnityPlayer.injectEvent(event);
    }

    /*API12*/
    public boolean onGenericMotionEvent(MotionEvent event) {
        return mUnityPlayer.injectEvent(event);
    }

    @Override
    protected void onUserLeaveHint() {
        super.onUserLeaveHint();

    }

    @Override
    public void onBackPressed() {
        super.onBackPressed();

        UnityPlayer.currentActivity.runOnUiThread(new Runnable() {
            @Override
            public void run() {
                mUnityPlayer.quit();
            }
        });

    }
}

对应的 XML 文件，

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/main_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <FrameLayout
        android:id="@+id/unity_player_layout"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />
</FrameLayout>

我的 AndroidManifest 文件看起来像

<?xml version="1.0" encoding="utf-8"?>

由于我是本地开发人员并且对 Unity 知之甚少，因此任何解决此问题的帮助都将非常有帮助！

我必须将以下行添加到 strings.xml 文件中以消除错误！

<string name="game_view_content_description">Game view</string>
