统一C#和Layar AndroidJavaException

Question

我正在尝试将Layar SDK集成到Unity中。但我有些问题。

这是AndroidManifest.xml

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

            <action android:name="com.layar.close_session" />
        </intent-filter>
    </receiver>
</application>

​

这是我的c#

using UnityEngine;

public class IntegrationLayar : MonoBehaviour {

private AndroidJavaObject LayarSDK = null;
private AndroidJavaObject activity = null;
private AndroidJavaObject context = null;

private string oauthKey = "code";
private string oauthSecret = "code2";


void Start ()
{
        if (LayarSDK == null)
        {
            using (AndroidJavaClass unityPlayer = new AndroidJavaClass("com.unity3d.player.UnityPlayer"))
            {
                activity = unityPlayer.GetStatic<AndroidJavaObject>("currentActivity");
                context = activity.Call<AndroidJavaObject>("getApplicationContext");

                //activity.Call("runOnUiThread", new AndroidJavaRunnable(runOnUiThread));
                Debug.Log("unity3D JAVA - Working");
            }

            using (AndroidJavaClass pluginClass = new AndroidJavaClass("com.layar.player"))
            {
                if (pluginClass != null)
                {
                    Debug.Log("Layar Java - Working");
                    pluginClass.CallStatic("initialize", context, oauthKey, oauthSecret);
                    pluginClass.CallStatic("startLayarActivity", context);
                }
            }
    }
}
}

错误：

AndroidJavaException: java.lang.ClassNotFoundException: com.layar.player

据我所知，它没有在Java中找到这样一个类。所以问题是什么？我打错电话了？

下面是到Layar 链接的链接

正如我在Layar中看到的那样，类是"LayarVisionSDK“。

AndroidJavaClass pluginClass = new AndroidJavaClass("com.layar.player.LayarVisionSDK")

所以也许这能行？

我当然做错了，但如果你们中的任何人有方向要遵循，我会很高兴地知道:)

更新1 :

这是APK的

Class LayarVisionSDK

java.lang.Object
com.layar.sdk.LayarVisionSDK

所以不要用

AndroidJavaClass pluginClass = new AndroidJavaClass("com.layar.player.LayarVisionSDK")

我在用

AndroidJavaObject LayarVisionSDK = new AndroidJavaObject("com.layar.sdk.LayarVisionSDK");

但还是没有成功。我在问自己是不是问题不在看上去的地方。

更新2 :

好吧！我找到了为什么会出现这个错误，API文档没有被更新，所以我签入了java包，并找到了“初始化”方法。

这是新的c#代码。

using (AndroidJavaClass pluginClass = new AndroidJavaClass("com.layar.sdk.LayarSDK"))
                {
                    if (pluginClass != null)
                    {
                        Debug.Log("SDK LAYAR FOUND !!! ");
                        pluginClass.CallStatic("initialize", context, oauthKey, oauthSecret);
                        Debug.Log("INITIALIZED");
                        //pluginClass.Call("startLayarActivity", context);
                    }
                }

，但我遇到了一个新错误:

AndroidJavaException: java.lang.NoClassDefFoundError: Failed resolution of: Landroid/support/v4/content/ContextCompat;

我错过了一个机器人库吗？

Answer 1

确保在Plugins/Android/libs文件夹下有android-support-v4.jar。

您可以从这里下载该文件。

Answer 2

好的，我要把它做好！

我只是添加了android支持库和kotlin库。

(谢谢你的帮助:)
