Question

尝试在Unity游戏上实现Android图像共享，我已经汇总了几个来源，这是我目前的代码.-

public static void shareImage(string subject, string title, string message, string imagePath) {
    #if UNITY_ANDROID

    AndroidJavaClass intentClass = new AndroidJavaClass("android.content.Intent");
    AndroidJavaObject intentObject = new AndroidJavaObject("android.content.Intent");
    intentObject.Call<AndroidJavaObject>("setAction", intentClass.GetStatic<string>("ACTION_SEND"));
    intentObject.Call<AndroidJavaObject>("setType", "image/png");
    intentObject.Call<AndroidJavaObject>("putExtra", intentClass.GetStatic<string>("EXTRA_SUBJECT"), subject);
    intentObject.Call<AndroidJavaObject>("putExtra", intentClass.GetStatic<string>("EXTRA_TITLE"), title);
    intentObject.Call<AndroidJavaObject>("putExtra", intentClass.GetStatic<string>("EXTRA_TEXT"), message);

    AndroidJavaClass uriClass = new AndroidJavaClass("android.net.Uri");
    AndroidJavaClass fileClass = new AndroidJavaClass("java.io.File");

    AndroidJavaObject uriObject = uriClass.CallStatic<AndroidJavaObject>("parse", "file://" + imagePath);

    intentObject.Call<AndroidJavaObject>("putExtra", intentClass.GetStatic<string>("EXTRA_STREAM"), uriObject);

    AndroidJavaClass unity = new AndroidJavaClass("com.unity3d.player.UnityPlayer");
    AndroidJavaObject currentActivity = unity.GetStatic<AndroidJavaObject>("currentActivity");
    currentActivity.Call("startActivity", intentObject);

    #endif
}

它对我来说没问题，share with...对话框被打开，但图像没有出现，我在Android控制台上看到错误.-

我猜测android期待EXTRA_STREAM成为ArrayList，但据我所知，只有在使用ACTION_SEND_MULTIPLE时才会这样。我可能会遗漏一些明显的东西吗？

最后，这个问题与例外无关，外部应用程序对附加文件没有可见性，因为我将它们保存在内部应用程序存储中。

在Unity WriteAccess->External (SDCard)上启用Player settings解决了这个问题。
