將unity3d項目嵌入到Android App中使用

建立一個新的AndroidStudio app項目。

 

1.添加庫文件：
拷貝unity安裝目錄下的庫文件：Unity\Editor\Data\PlaybackEngines\AndroidPlayer\Variations\mono\Release\Classes\classes.jar
到安卓項目目錄下：app\libs\unitylibs.jar

2.拷貝unity安裝目錄下的全部文件夾：Editor\Data\PlaybackEngines\AndroidPlayer\Variations\mono\Release\Libs
到安卓項目目錄下：app\src\main\jniLibs

3.拷貝資源
將unity項目的編譯好的apk包解壓後，把assets文件夾拷貝到安卓項目app\src\main中

4.AndroidManifest.xml添加UnityActivity和功能屬性:

<activity android:name=".UnityActivity" android:process="e.unitry3d" android:screenOrientation="landscape" 
android:configChanges="mcc|mnc|locale|touchscreen|keyboard|keyboardHidden|navigation|orientation|screenLayout|uiMode|screenSize|smallestScreenSize|fontScale|layoutDirection|density">
</activity>

<uses-feature android:glEsVersion="0x00020000" />
<uses-feature android:name="android.hardware.vulkan" android:required="false" />
<uses-feature android:name="android.hardware.touchscreen" android:required="false" />
<uses-feature android:name="android.hardware.touchscreen.multitouch" android:required="false" />
<uses-feature android:name="android.hardware.touchscreen.multitouch.distinct" android:required="false" />

 

 

5.添加一個新Activity：

import android.content.Intent;
import android.content.res.Configuration;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.KeyEvent;
import android.view.MotionEvent;
import android.view.View;
import android.widget.Button;
import android.widget.LinearLayout;

import com.unity3d.player.UnityPlayer;

public class UnityActivity extends AppCompatActivity {
    private LinearLayout mLlUnityContainer;
    Button btnBack;
    protected UnityPlayer mUnityPlayer;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        this.requestWindowFeature(1);
        super.onCreate(savedInstanceState);
        this.getWindow().setFormat(2);
        setContentView(R.layout.activity_unity);
        mLlUnityContainer = findViewById(R.id.unity_container);
        btnBack = findViewById(R.id.btn_back);

        this.mUnityPlayer = new UnityPlayer(this);
        this.mUnityPlayer.requestFocus();
        mLlUnityContainer.addView(mUnityPlayer.getView());

        btnBack.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                finish();
            }
        });
    }

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

    @Override
    protected void onDestroy() {
        this.mUnityPlayer.quit();
        super.onDestroy();
    }

    @Override
    protected void onPause() {
        super.onPause();
        this.mUnityPlayer.pause();
    }

    @Override
    protected void onResume() {
        super.onResume();
        this.mUnityPlayer.resume();
    }

    @Override
    public void onLowMemory() {
        super.onLowMemory();
        this.mUnityPlayer.lowMemory();
    }

    @Override
    public void onTrimMemory(int var1) {
        super.onTrimMemory(var1);
        if (var1 == 15) {
            this.mUnityPlayer.lowMemory();
        }

    }

    @Override
    public void onConfigurationChanged(Configuration var1) {
        super.onConfigurationChanged(var1);
        this.mUnityPlayer.configurationChanged(var1);
    }

    @Override
    public void onWindowFocusChanged(boolean var1) {
        super.onWindowFocusChanged(var1);
        this.mUnityPlayer.windowFocusChanged(var1);
    }

    @Override
    public boolean dispatchKeyEvent(KeyEvent var1) {
        return var1.getAction() == 2 ? this.mUnityPlayer.injectEvent(var1) : super.dispatchKeyEvent(var1);
    }

    @Override
    public boolean onKeyUp(int var1, KeyEvent var2) {
        return this.mUnityPlayer.injectEvent(var2);
    }

    @Override
    public boolean onKeyDown(int var1, KeyEvent var2) {
        return this.mUnityPlayer.injectEvent(var2);
    }

    @Override
    public boolean onTouchEvent(MotionEvent var1) {
        return this.mUnityPlayer.injectEvent(var1);
    }

    @Override
    public boolean onGenericMotionEvent(MotionEvent var1) {
        return this.mUnityPlayer.injectEvent(var1);
    }

}

activity_unity.xml代碼以下：

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

    <Button
        android:id="@+id/btn_back"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="back"
        android:textSize="16sp"/>

    <LinearLayout
        android:id="@+id/unity_container"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical">
    </LinearLayout>
</LinearLayout>
