Unity未打开插件活动，包似乎不正确

Question

我试图用this plugin打开一个android图像选择器，但它启动时发生错误。

调用脚本：

using System.Collections; 
using System.Collections.Generic; 
using UnityEngine; 
using UnityEngine.UI; 
using LukeWaffel.AndroidGallery; 

public class LoadImageWithMagic : MonoBehaviour { 

    public Image image; 

    // Use this for initialization 
    void Start() { 

    } 

    // Update is called once per frame 
    void Update() { 

    } 

    public void OpenGallery() { 
     Debug.Log ("It clicked"); 
     AndroidGallery.Instance.OpenGallery (GalleryCallback); 
    } 

    public void GalleryCallback() { 
     image.material.mainTexture = AndroidGallery.Instance.GetTexture(); 
     AndroidGallery.Instance.ResetOutput(); 
    } 
} 

的AndroidManifest.xml：

<?xml version="1.0" encoding="utf-8"?> 
<manifest 
    xmlns:android="http://schemas.android.com/apk/res/android" 
    package="com.unity3d.player" 
    xmlns:tools="http://schemas.android.com/tools" 
    android:installLocation="preferExternal" 
    android:versionCode="1" 
    android:versionName="1.0"> 

    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" /> 

    <supports-screens 
     android:smallScreens="true" 
     android:normalScreens="true" 
     android:largeScreens="true" 
     android:xlargeScreens="true" 
     android:anyDensity="true"/> 

    <application 
     android:theme="@style/UnityThemeSelector" 
     android:icon="@drawable/app_icon" 
     android:label="@string/app_name" 
     android:debuggable="true"> 
     <activity android:name="com.unity3d.player.UnityPlayerActivity" 
        android:label="@string/app_name"> 
      <intent-filter> 
       <action android:name="android.intent.action.MAIN" /> 
       <category android:name="android.intent.category.LAUNCHER" /> 
      </intent-filter> 
      <meta-data android:name="unityplayer.UnityActivity" android:value="true" /> 
     </activity> 
     <activity android:name= "com.lukewaffel.androidgallery.Gallery"></activity> 
    </application> 
</manifest> 

从logcat的错误：

看来，这个问题是团结，是在前面加上我的包到包的插件，导致它不被发现。我试图将我的软件包更改为插件的包，但它仍然有相同的错误。

我已经尝试重新安装应用程序，仍然无法打开图库。

我发现问题是所有的插件文件都放在了一个子目录中，所以统一无法找到AndroidManifest.xml。将所有项目移出子目录后，画廊打开。

作为一个说明任何人复制上面的代码，然后我发现了一个不相关的错误，image.material.mainTexture = AndroidGallery.Instance.GetTexture();应image.sprite = AndroidGallery.Instance.GetSprite();
