使用意图从Unity app向Android app发送数据

Question

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）。在用户玩完游戏(AppB)并单击logout按钮后，它将把游戏记录（字符串html" target="_blank">数组）发送回appa。

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);

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”作为Unity中的类名，但也出现了同样的错误。

这是我得到的错误：

请好心帮帮我！提前感谢您的帮助！：）

替换代码的这一行

currentActivity.Call ("startActivity", sendIntent);

用这个

AndroidJavaObject jChooser = intentClass.CallStatic<AndroidJavaObject>("createChooser", sendIntent, "Share Via");
currentActivity.Call("startActivity", jChooser);
