这个问题已经在这里有了答案:




已关闭8年。






尝试启动并运行GCM,但我的设备正在发送注册请求,但没有收到来自GCM服务器的响应。下面,我包括 list 和GCMIntentService定义,以及向GCM服务器注册的调用。很久以来我一直在盯着它,如果可能的话,我可能会遗漏一些明显的东西,对不起。

欢迎所有想法!

这是我的 list :

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="PACKAGE"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="15" />

    <permission android:name="PACKAGE.permission.C2D_MESSAGE" android:protectionLevel="signature" />
    <uses-permission android:name="PACKAGE.permission.C2D_MESSAGE" />
    <uses-permission android:name="com.google.android.c2dm.permission.RECEIVE" />
    <uses-permission android:name="android.permission.WAKE_LOCK" />
    <uses-permission android:name="android.permission.INTERNET" />

    <application
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >

        <service android:name=".GCMIntentService"
            android:enabled="true"/>

        <receiver
            android:name="com.google.android.gcm.GCMBroadcastReceiver"
            android:permission="com.google.android.c2dm.permission.SEND" >
            <intent-filter>
                <action android:name="com.google.android.c2dm.intent.RECEIVE" />
                <action android:name="com.google.android.c2dm.intent.REGISTRATION" />

                <category android:name="PACKAGE.GCMIntentService" />
            </intent-filter>
        </receiver>


        <activity
            android:name=".MainActivity"
            android:label="@string/title_activity_main" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>

这是我的GCMIntentService,用于处理来自GCM的退货:
import com.google.android.gcm.GCMBaseIntentService;
import android.content.Context;
import android.content.Intent;
import android.util.Log;


public class GCMIntentService extends GCMBaseIntentService {
    public static String TAG = "GCMIntentService";

    public GCMIntentService(String senderId) {
        super(senderId);
        Log.d("GCMIntentService", senderId);
    }

    @Override
    protected void onError(Context arg0, String arg1) {
        Log.d("onError", arg1);
    }

    @Override
    protected boolean onRecoverableError(Context context, String errorId){
        Log.d("onRecoverableError", errorId);
        return false;
    }

    @Override
    protected void onMessage(Context arg0, Intent arg1) {
        Log.d("onMessage", String.valueOf(arg1));
    }

    @Override
    protected void onRegistered(Context arg0, String arg1) {
        Log.d("onRegistered", arg1);
    }

    @Override
    protected void onUnregistered(Context arg0, String arg1) {
        Log.d("onUnregistered", arg1);
    }
}

我尝试在我的主类的onCreate方法中注册以下内容:
GCMRegistrar.checkDevice(this);
GCMRegistrar.checkManifest(this);

final String regId = GCMRegistrar.getRegistrationId(this);
if (regId.equals("")) {
    GCMRegistrar.register(this, SENDER_ID);
} else {
    Log.d(TAG, "Already registered");
}

我尝试了Raz的建议,但遇到以下错误:

最佳答案

在 list 中尝试以下操作:

<receiver
        android:name="com.google.android.gcm.GCMBroadcastReceiver"
        android:permission="com.google.android.c2dm.permission.SEND" >
        <intent-filter>
            <action android:name="com.google.android.c2dm.intent.RECEIVE" />
            <action android:name="com.google.android.c2dm.intent.REGISTRATION" />

            <category android:name="eimmer.liav.elucidate.gcm2" />
        </intent-filter>
    </receiver>

类别名称必须是您的应用程序包。

如果服务使用相同的程序包名称,则将其保留,就像您将其更改为实际程序包而不是.GCMIntentService一样,但是您还需要extendoverride GCMBroadcastReceiver

如果您的软件包不是eimmer.liav.elucidate.gcm2.GCMIntentService,则必须扩展 GCMBroadcastReceiver 并覆盖函数 getGCMIntentServiceClassName()
在该函数中,以字符串示例eimmer.liav.example.GCMIntentService返回实际的包和类。

同样不要忘了将接收者名称更改为新名称。例子:
 <receiver
        android:name="eimmer.liav.example.MyGCMBroadcastReceiver"
        android:permission="com.google.android.c2dm.permission.SEND" >
        <intent-filter>
            <action android:name="com.google.android.c2dm.intent.RECEIVE" />
            <action android:name="com.google.android.c2dm.intent.REGISTRATION" />

            <category android:name="eimmer.liav.elucidate.gcm2" />
        </intent-filter>
    </receiver>

进一步将您的服务名称更改为:
<service android:name="eimmer.liav.example.GCMIntentService"
            android:enabled="true"/>

根据Google的另一件事,您需要将您的构造函数更改为默认的并发送一些类似这样的字符串:
public GCMIntentService() {
        super("Test");
    }

据我所知,该字符串并不是很重要。

玩得开心。
