android - GCMRegistrar.getRegistrationId(context) 无法获取设备 ID

Question

我一直在努力为我的应用程序获取设备 ID。这是我的代码

这段代码来 self 的类(class)

GCMRegistrar.checkDevice(this);
GCMRegistrar.checkManifest(this);
device_key = GCMRegistrar.getRegistrationId(this);

此代码来自 list 文件

    <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="com.k2b.kluebook" />
        </intent-filter>
    </receiver>
    <service android:name=".GCMIntentService" />

我在主包中编写了 GCMIntentService 类。

public class GCMIntentService extends GCMBaseIntentService {

private static final String TAG = "GCMIntentService";

public GCMIntentService() {
    super(SENDER_ID);
}

/**
 * Method called on device registered
 **/
@Override
protected void onRegistered(Context context, String registrationId) {
    Log.i(TAG, "Device registered: regId = " + registrationId);
    displayMessage(context, "Your device registred with GCM");
    Log.d("NAME", "gcm");
    ServerUtilities.register(context, "gcm", "gcm", registrationId);
}

/**
 * Method called on device un registred
 * */
@Override
protected void onUnregistered(Context context, String registrationId) {
    Log.i(TAG, "Device unregistered");
    displayMessage(context, getString(R.string.gcm_unregistered));
    ServerUtilities.unregister(context, registrationId);
}

/**
 * Method called on Receiving a new message
 * */
@Override
protected void onMessage(Context context, Intent intent) {
    Log.i(TAG, "Received message");
    String message = intent.getExtras().getString("mes");
    displayMessage(context, message);
    // notifies user
    generateNotification(context, message);
}

/**
 * Method called on receiving a deleted message
 * */
@Override
protected void onDeletedMessages(Context context, int total) {
    Log.i(TAG, "Received deleted messages notification");
    String message = getString(R.string.gcm_deleted, total);
    String key = "failed";
    displayMessage(context, message);
    // notifies user
    generateNotification(context, message);
}

/**
 * Method called on Error
 * */
@Override
public void onError(Context context, String errorId) {
    Log.i(TAG, "Received error: " + errorId);
    displayMessage(context, getString(R.string.gcm_error, errorId));
}

@Override
protected boolean onRecoverableError(Context context, String errorId) {
    // log message
    Log.i(TAG, "Received recoverable error: " + errorId);
    displayMessage(context,
            getString(R.string.gcm_recoverable_error, errorId));
    return super.onRecoverableError(context, errorId);
}

/**
 * Issues a notification to inform the user that server has sent a message.
 */
private static void generateNotification(Context context, String message) {
    int icon = R.drawable.ic_launcher;
    long when = System.currentTimeMillis();
    NotificationManager notificationManager = (NotificationManager) context
            .getSystemService(Context.NOTIFICATION_SERVICE);
    Notification notification = new Notification(icon, message, when);
    String title = context.getString(R.string.app_name);
    Intent notificationIntent = new Intent(context,
            FragmentOpenActivity.class);
    notificationIntent.putExtra(key, key);
    notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP
            | Intent.FLAG_ACTIVITY_SINGLE_TOP);
    PendingIntent intent = PendingIntent.getActivity(context, 0,
            notificationIntent, 0);
    notification.setLatestEventInfo(context, title, message, intent);
    notification.flags |= Notification.FLAG_AUTO_CANCEL;
    notification.defaults |= Notification.DEFAULT_SOUND;
    notification.defaults |= Notification.DEFAULT_VIBRATE;
    notificationManager.notify(0, notification);

}

我进行了如此多的搜索，但我找不到解决方案请帮我找到解决方案

好的，让我把我所做的放在这里:

1. 首先，您必须在 Google 中创建项目并获取 SENDER_ID。
2. 然后，我有这个方法来注册 GCM 并在 OnCreate 上调用它:

:

private void registerGCM() {
        // Make sure the device has the proper dependencies.
        GCMRegistrar.checkDevice(getApplicationContext());

        // Make sure the manifest was properly set - comment out this line
        // while developing the app, then uncomment it when it's ready.
        GCMRegistrar.checkManifest(getApplicationContext());
        GCMRegistrar.register(getApplicationContext(), GCMIntentService.SENDER_ID);
        if (GCMRegistrar.isRegistered(getApplicationContext())) {
            String registrationCGMId = GCMRegistrar.getRegistrationId(getApplicationContext());
        }else{
            GCMRegistrar.register(getApplicationContext(), GCMIntentService.SENDER_ID);
        }
    }

如果错误仍然存​​在，请检查 Google Play 应用(如果运行正常)、互联网连接或手机时钟时间。
