java - Unity 的 GCM 插件，找不到方法 GCMRegistrar.checkDevice

Question

我之前看过有关此问题的帖子，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 中。

当然，他的教程是针对Mobclix的，我正在尝试构建一个GCM插件，但过程是相似的。我想我已经包含了我需要的所有依赖项。在 Eclipse 中，在项目中我看到“Android 依赖项”，其中包括:classes.jar(包含 Unity 播放器 Hook )、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”。

完成所有这些后，当我在设备上部署测试时，我仍然看到 2 个错误，第一个是标题错误，其次是 NoClassDefFoundError。我已经测试了 3 种设备的兼容性，目前我使用的是 2.3.3 的 Motorola(所以它应该支持 GCM)。如果有人知道还有什么可能导致此问题，请告诉我。我对 Eclipse(甚至 Java)不太熟悉，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"));
    }
}

Answer 1

I had manually copied gcm.jar and classes.jar to the "libs" folder(I am using ADT 17), then selected to Add To Build Path.

我不知道classes.jar是什么。

对于常规 Android 应用程序来说，只需在 libs/ 文件夹中包含 gcm.jar 就足够了 - 使用“添加到构建路径”手动更改构建路径是一个简单的方法错误。

Unity 插件的流程是否不同，我不能说。

该错误表明您的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，您没有 gcm.jar 位于 libs/ 中，或者手动将其添加到构建路径会阻止将其添加到您的 APK)。
