Question

我打电话给RegistrationIntentService:

    if (checkPlayServices()) {
        Log.i("udazzT", "check servicies");
        // Start IntentService to register this application with GCM.
        Intent intent2 = new Intent(this, RegistrationIntentService.class);
        startService(intent2);
    }

但是我在 RegistrationIntentService 中看不到任何日志：

public class RegistrationIntentService extends IntentService {

    private static final String TAG = "RegIntentService";
    private static final String[] TOPICS = {"global"};

    public RegistrationIntentService() {
        super(TAG);
    }

    @Override
    protected void onHandleIntent(Intent intent) {
        Log.i("udazzT", "setting token");
        SharedPreferences sharedPreferences = PreferenceManager.getDefaultSharedPreferences(this);

        try {
            // In the (unlikely) event that multiple refresh operations occur simultaneously,
            // ensure that they are processed sequentially.
            synchronized (TAG) {
                // [START register_for_gcm]
                // Initially this call goes out to the network to retrieve the token, subsequent calls
                // are local.
                // [START get_token]
                Log.i("udazzT", "setting token 2");
                InstanceID instanceID = InstanceID.getInstance(this);
                String token = instanceID.getToken(getString(R.string.gcm_defaultSenderId),
                        GoogleCloudMessaging.INSTANCE_ID_SCOPE, null);
                // [END get_token]
                Log.i(TAG, "GCM Registration Token: " + token);

                // TODO: Implement this method to send any registration to your app's servers.
                sendRegistrationToServer(token);

                // Subscribe to topic channels
                subscribeTopics(token);

                // You should store a boolean that indicates whether the generated token has been
                // sent to your server. If the boolean is false, send the token to your server,
                // otherwise your server should have already received the token.
                sharedPreferences.edit().putBoolean(QuickstartPreferences.SENT_TOKEN_TO_SERVER, true).apply();
                // [END register_for_gcm]
            }
        } catch (Exception e) {
            Log.d(TAG, "Failed to complete token refresh", e);
            // If an exception happens while fetching the new token or updating our registration data
            // on a third-party server, this ensures that we'll attempt the update at a later time.
            sharedPreferences.edit().putBoolean(QuickstartPreferences.SENT_TOKEN_TO_SERVER, false).apply();
        }
        // Notify UI that registration has completed, so the progress indicator can be hidden.
        Intent registrationComplete = new Intent(QuickstartPreferences.REGISTRATION_COMPLETE);
        LocalBroadcastManager.getInstance(this).sendBroadcast(registrationComplete);
    }

    /**
     * Persist registration to third-party servers.
     *
     * Modify this method to associate the user's GCM registration token with any server-side account
     * maintained by your application.
     *
     * @param token The new token.
     */
    private void sendRegistrationToServer(String token) {
        // Add custom implementation, as needed.
    }

    /**
     * Subscribe to any GCM topics of interest, as defined by the TOPICS constant.
     *
     * @param token GCM token
     * @throws IOException if unable to reach the GCM PubSub service
     */
    // [START subscribe_topics]
    private void subscribeTopics(String token) throws IOException {
        for (String topic : TOPICS) {
            GcmPubSub pubSub = GcmPubSub.getInstance(this);
            pubSub.subscribe(token, "/topics/" + topic, null);
        }
    }
    // [END subscribe_topics]

}

Answer 1

确保它已在您的清单中注册。

<service android:name=".RegistrationIntentService"
             android:exported="false" />

Answer 2

你认为像这里一样添加所有需要的东西吗googlesamples

Answer 3

只需添加此

<intent-filter>
<action android:name="com.google.android.c2dm.intent.RECEIVE" />
<category android:name="<PACKAGE-NAME>" />
</intent-filter>

in manifest.xml of "GcmReceiver" & "MyGcmListenerService" 在我的代码中它看起来像下面这样。

    <receiver
        android:name="com.google.android.gms.gcm.GcmReceiver"
        android:exported="true"
        android:permission="com.google.android.c2dm.permission.SEND" >
        <intent-filter>
            <action android:name="com.google.android.c2dm.intent.RECEIVE" />
            <category android:name="<PACKAGE-NAME>" />
        </intent-filter>
    </receiver>
    <!-- [END gcm_receiver] -->

    <!-- [START gcm_listener] -->
    <service
        android:name="<PACKAGE-NAME>.MyGcmListenerService"
        android:exported="false" >
        <intent-filter>
            <action android:name="com.google.android.c2dm.intent.RECEIVE" />
            <category android:name="<PACKAGE-NAME>" />
        </intent-filter>
    </service>
    <!-- [END gcm_listener] -->
    <!-- [START instanceId_listener] -->

就我而言，它正在工作...可能对您有所帮助。祝你好运

检查您是否在接收者意图过滤器中添加了以下行

因为它在 GCM 文档中提到为：

如果要支持 4.4 之前的 KitKat 设备，请将以下操作添加到接收器的 Intent 过滤器声明中：

Android - 没有获得 GCM 令牌

Android - not getting GCM token
