使用Unity应用程序的意图向Android应用程序发送数据

我有两个独立的应用程序，AppA（使用Android Studio开发）和AppB（使用Unity开发） . AppA将推出AppB（这是一款游戏应用） . 用户完成游戏（AppB）并单击注销按钮后，它会将游戏记录（字符串数组）发送回AppA .

目前，AppA能够启动AppB，但我无法让AppB将游戏记录（使用意图）发送回AppA .

AppA的StartGameActivity：

Intent launchGameIntent = getPackageManager().getLaunchIntentForPackage("com.joy.AppB"); 
startActivity(launchGameIntent);

retrieveGameRecords = (Button) findViewById(R.id.retrieveRecordsButton);
retrieveGameRecords.setOnClickListener(new View.OnClickListener() {
    public void onClick(View v) {

        //Retrieving game records from game app
        database = new gameDbHelper(StartGameActivity.this.getApplicationContext()).getWritableDatabase();
        Intent intent = getIntent();
        String[] gameRecords_array = intent.getStringArrayExtra("gameRecord");
        System.out.println("Number of game records received from game : " + gameRecords_array.length);

AppA的Android Manifest：

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

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.FLASHLIGHT" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

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

<application
    android:largeHeap="true"
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme"
    android:name="android.support.multidex.MultiDexApplication">

    <activity
        android:name="com.joy.AppA.views.activities.StartGameActivity"
        android:label="Start Game">
        <intent-filter>
            <action android:name="com.joy.AppA.views.activities.LAUNCH_IT"/>
            <category android:name="android.intent.category.DEFAULT" />
        </intent-filter>
        <meta-data
            android:name="android.support.PARENT_ACTIVITY"
            android:value=".views.activities.DashboardActivity" />
    </activity>

AppB的C＃代码：

public void sendDataToAppAFunction()
{
    int counter = 0;
    string className = "com.joy.AppA"; 
    string[] gameRecord_strArray = new string[100];
    AndroidJavaObject launchIntent = null;

    AndroidJavaClass Intent = new AndroidJavaClass (className);
    AndroidJavaObject sendIntent = new AndroidJavaObject (className);

    AndroidJavaClass unityPlayer = new AndroidJavaClass("com.unity3d.player.UnityPlayer");
    AndroidJavaObject currentActivity = unityPlayer.GetStatic<AndroidJavaObject>("currentActivity");

    sendIntent.Set<AndroidJavaObject> ("gameRecord", javaArrayFromCS(gameRecord_strArray));
    sendIntent.Call<AndroidJavaObject> ("putExtra", Intent.GetStatic<string[]>("gameRecord"), gameRecord_strArray);
    currentActivity.Call ("startActivity", sendIntent);
}

private AndroidJavaObject javaArrayFromCS(string [] values) {
    AndroidJavaClass arrayClass = new AndroidJavaClass ("java.lang.reflect.Array");
    AndroidJavaObject arrayObject = arrayClass.CallStatic<AndroidJavaObject> ("newInstance", new AndroidJavaClass ("java.lang.String"), values.Length);
    for (int i = 0; i < values.Length; ++i) {
        arrayClass.CallStatic ("set", arrayObject, i, new AndroidJavaObject ("java.lang.String", values [i]));
    }
    return arrayObject;
}

我尝试将 "com.joy.AppA.views.activities.StartGameActivity" 用于Unity中的className，但它也给出了相同的错误 .

这是我得到的错误：

I / Unity：AndroidJavaException：java.lang.ClassNotFoundException：com.joy.AppA java.lang.ClassNotFoundException：com.joy.AppA at java.lang.Class.classForName（Native Method）at java.lang.Class.forName（ Class.java:309）at java.lang.Class.forName（Class.java:273）at com.unity3d.player.UnityPlayer.nativeRender（Native Method）at com.unity3d.player.UnityPlayer.a（Unknown Source）at at com.unity3d.player.UnityPlayer $ c $ 1.handleMessage（Unknown Source）位于android.os.Handler.dispatchMessage（Handler.java:98），位于com.unity3d的android.os.Looper.loop（Looper.java:135） .player.UnityPlayer $ c.run（Unknown Source）引起：java.lang.ClassNotFoundException：在路径上找不到类“com.joy.AppA”：DexPathList [[zip file“/data/app/com.joy dalvik.system.BaseDexClassLoader.findClass中的.AppB-1 / base.apk“]，nativeLibraryDirectories = [/ data / app / com.joy.AppB-1 / lib / arm，/ vendor / lib，/ system / lib]] （BaseDexClassLoader.java:56）在java.lang.ClassLoader的java.lang.ClassLoader.loadClass（ClassLoader.java:511）
