【中文标题】Unity 的 GCM 插件，找不到方法 GCMRegistrar.checkDevice【英文标题】：GCM Plugin for Unity, Could not find method GCMRegistrar.checkDevice 【发布时间】：2013-05-14 17:01:26 【问题描述】：我以前看过有关此的帖子，但似乎没有一个解决方案对我有用。
我下载/安装了 Eclipse for Mobile(http://www.eclipse.org/downloads/packages/eclipse-mobile-developers/junosr2)，并创建了一个 android 应用程序，然后使用从这个人的视频教程 (http://www.youtube.com/watch?v=TazEIIoNVA0) 中找到的说明将其设为库，以便我可以将其放入 Unity。
当然，他的教程是针对 Mobclix 的，我正在尝试构建一个 GCM 插件，但过程类似。我想我已经包含了我需要的所有依赖项。在 Eclipse 中，我在项目中看到“Android Dependencies”，其中包括：classes.jar（包含 Unity 播放器挂钩）、gcm.jar 和 android-support-v4.jar。在“Android 4.2.2”下，我看到“android.jar”。在“引用库”下，我看到了 classes.jar 和 gcm.jar。在关于此错误的其他论坛帖子（例如：GCM : java.lang.noclassdeffounderror: com.google.android.gcm.GCMRegistrar）之后，我手动将 gcm.jar 和 classes.jar 复制到“libs”文件夹（我使用的是 ADT 17），然后选择添加到构建路径。
在这一切之后，当我部署到设备上进行测试时，我仍然看到 2 个错误，第一个是标题错误，然后是 NoClassDefFoundError。我已经通过 3 台设备进行兼容性测试，我目前使用的是带有 2.3.3 的摩托罗拉（所以它应该支持 GCM）。如果有人知道还有什么可能导致这种情况，请告诉我。我对 Eclipse（或者甚至 Java）不是很熟悉，所以我打赌它以某种方式存在于 Java 项目中。

代码很简单，只有两个文件
RegisterActivity.java：
package com.my_provider.gcm;
import android.os.Bundle;
import android.app.Activity;
import com.google.android.gcm.GCMRegistrar;
import com.unity3d.player.UnityPlayer;
import com.unity3d.player.UnityPlayerActivity;
public class RegisterActivity extends UnityPlayerActivity
public static String ProjectID;
@Override
protected void onCreate(Bundle savedInstanceState)
super.onCreate(savedInstanceState);
public static void RegisterDevice(final Activity activity)
try
GCMRegistrar.checkDevice(activity);
GCMRegistrar.checkManifest(activity);
final String regId = GCMRegistrar.getRegistrationId(activity);
if (regId.equals(""))
GCMRegistrar.register(activity, ProjectID);
catch(Exception e)
UnityPlayer.UnitySendMessage("ErrorHandlerGameObject", "OnError", e.getMessage());
最后是服务 GCMBroadcastReceiver.java：
package com.my_provider.gcm;
import android.content.Context;
import android.content.Intent;
import com.google.android.gcm.GCMBaseIntentService;
import com.unity3d.player.UnityPlayer;
public class GCMBroadcastReceiver extends GCMBaseIntentService
public GCMBroadcastReceiver()
super(RegisterActivity.ProjectID);
@Override
protected void onRegistered(Context context, String deviceID)
UnityPlayer.UnitySendMessage("DeviceRegisteringGameObject", "OnRegisteredAndroidDevice", deviceID);
@Override
protected void onUnregistered(Context context, String deviceID)
UnityPlayer.UnitySendMessage("DeviceRegisteringGameObject", "OnUnregisteredAndroidDevice", deviceID);
@Override
public void onError(Context context, String errorID)
UnityPlayer.UnitySendMessage("DeviceRegisteringGameObject", "OnError", errorID);
@Override
protected void onMessage(Context context, Intent intent)
UnityPlayer.UnitySendMessage("DeviceRegisteringGameObject", "OnMessageAndroid", intent.getStringExtra("message"));
【问题讨论】：
【参考方案1】：我已手动将 gcm.jar 和 classes.jar 复制到“libs”文件夹（我使用的是 ADT 17），然后选择添加到构建路径。
我不知道classes.jar 是什么。
对于普通的 Android 应用来说，在 libs/ 文件夹中只包含 gcm.jar 就足够了——使用“添加到构建路径”手动更改构建路径是错误的。
Unity插件的流程是否不同，我不能说。
错误表明您在编译时构建路径中有gcm.jar（例如，通过添加到构建路径）但它不在APK中（例如，您在libs/中没有gcm.jar，或手动将其添加到您的构建路径以防止它被添加到您的 APK）。
【讨论】：
Classes.jar 很难找到，它包含 Unity 特定的钩子，更多信息在这里：answers.unity3d.com/questions/182912/…。我将尝试在不将 gcm.jar 添加到我的构建路径的情况下进行构建，看看是否有任何作用 看起来像 Unity，您需要确保它们不在构建路径中，而是放在您制作的插件 jar 旁边，所以是的，这似乎解决了问题。谢谢以上是关于Unity 的 GCM 插件，找不到方法 GCMRegistrar.checkDevice的主要内容，如果未能解决你的问题，请参考以下文章
