我遇到的情况是，全新安装的 Android 应用程序在到达onRegistered我GCMIntentService文件中的函数后会崩溃。GCM 注册成功，我可以在下次打开应用程序时检索 GCM 注册 ID，但我不希望它在用户第一次打开它时崩溃。

我用它来要求注册：

GCMRegistrar.checkDevice(this);
GCMRegistrar.checkManifest(this);
String regId = GCMRegistrar.getRegistrationId(this);
if (regId.equals("")) {
     GCMRegistrar.register(this, getResources().getString(R.string.gcmToken));
}

这是我的GCMIntentService文件

public class GCMIntentService extends GCMBaseIntentService {

    private static final String LOG_TAG = "GCM";

    public GCMIntentService() {
        super( "###############" ); // use my GCM ID
        // TODO Auto-generated constructor stub
        Log.i( LOG_TAG, "GCMIntentService constructor called" );
    }

    @Override
    protected void onError( Context arg0, String errorId ) {
        // TODO Auto-generated method stub
        Log.i( LOG_TAG, "GCMIntentService onError called: " + errorId );
    }

    @Override
    protected void onMessage( Context arg0, Intent intent ) {
        // TODO Auto-generated method stub
        Log.i( LOG_TAG, "GCMIntentService onMessage called" );
        Log.i( LOG_TAG, "Message is: " + intent.getStringExtra( "message" ) );
    }

    @Override
    protected void onRegistered( Context arg0, String registrationId ) {
        // TODO Auto-generated method stub
        Log.i( LOG_TAG, "GCMIntentService onRegistered called" );
        Log.i( LOG_TAG, "Registration id is: " + registrationId );

        // ! ! ! CRASHES HERE ! ! !

    }

    @Override
    protected void onUnregistered( Context arg0, String registrationId ) {
        // TODO Auto-generated method stub
        Log.i( LOG_TAG, "GCMIntentService onUnregistered called" );
        Log.i( LOG_TAG, "Registration id is: " + registrationId );
    }
}

这是 LogCat 的崩溃部分

您是否在 Manifest 上注册了 Receiver and Intent 服务？

例子：

<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_NAME" />
                </intent-filter>
            </receiver>
            <service android:name=".GCMIntentService"></service>

您可以从以下路径获得正确的 jar：

android-sdk-windows\extras\google\gcm\gcm-client\dist

看看这个例子：
