Question

我正在尝试使用this plugin打开Android图片选择器，但启动时会出错。

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: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>

logcat错误：

看来问题是Unity正在将我的软件包添加到插件的包中，导致无法找到它。我试图将我的包更改为插件的包，但它仍然有同样的错误。

我已尝试重新安装该应用，但仍然无法让图库打开。

Answer 1

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Unity找不到AndroidManifest.xml。将所有项目移出子目录后，图库就会打开。

作为复制上述代码的任何人的注释，我随后发现了一个无关的错误，image.material.mainTexture = AndroidGallery.Instance.GetTexture ();应为image.sprite = AndroidGallery.Instance.GetSprite ();

Unity没有打开插件活动，包似乎不正确
