unity AndroidJavaClass unityPlayer = null; AndroidJavaObject activity = null; AndroidJavaObject pm = null; AndroidJavaObject joIntent = null; try { unityPlayer = new AndroidJavaClass(Const.UnityPlayer); activity = unityPlayer.GetStatic<AndroidJavaObject>("currentActivity"); pm = activity.Call<AndroidJavaObject>("getPackageManager"); joIntent = pm.Call<AndroidJavaObject>("getLaunchIntentForPackage", packageName); activity.Call("startActivity", joIntent); } intent中添加一个数据

可以在创建Intent对象时，使用`putExtra()`方法添加数据。具体实现方式如下：

using UnityEngine;

public class IntentExample : MonoBehaviour {

    private const string packageName = "your.package.name";
    private const string extraKey = "your_extra_key";
    private const string extraValue = "your_extra_value";

    void Start () {
        AndroidJavaClass unityPlayerClass = new AndroidJavaClass("com.unity3d.player.UnityPlayer");
        AndroidJavaObject activity = unityPlayerClass.GetStatic<AndroidJavaObject>("currentActivity");
        AndroidJavaObject intent = activity.Call<AndroidJavaObject>("getIntent");

        // 添加数据到Intent中
        intent.Call<AndroidJavaObject>("putExtra", extraKey, extraValue);

        // 启动应用程序
        AndroidJavaObject pm = activity.Call<AndroidJavaObject>("getPackageManager");
        AndroidJavaObject joIntent = pm.Call<AndroidJavaObject>("getLaunchIntentForPackage", packageName);
        activity.Call("startActivity", joIntent);
    }
}

通过上述代码，你就可以在Intent中添加数据，并启动应用程序。在被启动的应用程序中，你可以通过获取启动程序的Intent数据，获取到这个数据。具体实现方式可以参考我之前回答的问题。
