Google 云消息服务和侦听器从未调用 Android

Question

我正在尝试在 Android Studio 中配置 GCM 以在我的应用程序中接收推送通知。但是我的 gcm 服务和监听器从来没有被调用过。

代码如下：

manifest.xml:

    <?xml version="1.0" encoding="utf-8"?>
    <manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="mypackagename"
    >

    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    <uses-permission android:name="android.permission.INTERNET" />

    <!-- Keeps the processor from sleeping when a message is received. -->
    <uses-permission android:name="android.permission.WAKE_LOCK" />
    <uses-permission android:name="com.google.android.c2dm.permission.RECEIVE"   />

    <permission android:protectionLevel="signature"  android:name="mypackagename.permission.C2D_MESSAGE" />
    <uses-permission android:name="mypackagename.permission.C2D_MESSAGE" />


    <application
        android:name=".MyApp"
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTemaBase" >
        <meta-data
            android:name="com.google.android.gms.version"
            android:value="@integer/google_play_services_version" />

        <activity
            android:name=".MainActivity"
            android:icon="@drawable/ic_launcher"
            android:launchMode="singleTask">


        </activity>


        <!-- [START gcm_receiver] -->
        <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.REGISTRATION" />

        </receiver>
        <!-- [END gcm_receiver] -->

        <!-- [START gcm_listener] -->
        <service
            android:name="mypackagename.push.MyGcmListenerService"
            android:exported="false" >
            <intent-filter>
                <action android:name="com.google.android.c2dm.intent.RECEIVE" />
            </intent-filter>
        </service>
        <!-- [END gcm_listener] -->
        <!-- `enter code here`[START instanceId_listener] -->
        <service
            android:name="mypackagename.push.MyInstanceIDListenerService"
            android:exported="false">
            <intent-filter>
                <action android:name="com.google.android.gms.iid.InstanceID"/>
            </intent-filter>
        </service>
        <!-- [END instanceId_listener] -->
        <service
            android:name="mypackagename.push.RegistrationIntentService"
            android:exported="false">
            <intent-filter>
                <action android:name="com.google.android.c2dm.intent.RECEIVE" />
            </intent-filter>
        </service>
    </application>
</manifest>

MyInstanceIDListenerService.java:

import android.content.Intent;
import com.google.android.gms.iid.InstanceIDListenerService;

public class MyInstanceIDListenerService extends InstanceIDListenerService {

    // [START refresh_token]
    @Override
    public void onTokenRefresh() {
        // Fetch updated Instance ID token and notify our app's server of any changes (if applicable).
        Intent intent = new Intent(this, RegistrationIntentService.class);
        startService(intent);
    }
    // [END refresh_token]
}

MyGcmListenerService.java:

    public class MyGcmListenerService extends GcmListenerService {

        // [START receive_message]
        @Override
        public void onMessageReceived(String from, Bundle data) {
            String message = data.getString("message");
            Log.d(TAG, "From: " + from);
            Log.d(TAG, "Message: " + message);

            if (from.startsWith("/topics/")) {
                // message received from some topic.
            } else {
                // normal downstream message.
            }

               // sendNotification(message);
            // [END_EXCLUDE]
        }
        // [END receive_message]

RegistrationIntentService.java:

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) {
        SharedPreferences sharedPreferences = PreferenceManager.getDefaultSharedPreferences(this);



        try {
            // [START register_for_gcm]
            // Initially this call goes out to the network to retrieve the token, subsequent calls
            // are local.
            // R.string.gcm_defaultSenderId (the Sender ID) is typically derived from google-services.json.
            // See https://developers.google.com/cloud-messaging/android/start for details on this file.
            // [START get_token]
            InstanceID instanceID = InstanceID.getInstance(this);
            String token = instanceID.getToken(getString(R.string.gcm_defaultSenderId),
                    GoogleCloudMessaging.INSTANCE_ID_SCOPE, null);
            // [END get_token]


            // TODO: Implement this method to send any registration to your app's servers.
            //sendRegistrationToServer(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);
            Utils.LogDebug(TAG, "GCM Failed to complete token refresh: " + Utils.getPrintStackTraceToString(e));


            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);
    }

顶部build.gradle:

....
dependencies {
        classpath 'com.android.tools.build:gradle:2.0.0-alpha9'
        classpath 'com.google.gms:google-services:2.0.0-alpha9'

    }

应用build.gradle:

....
dependencies {
    compile 'com.android.support:multidex:+'    
    compile 'com.google.android.gms:play-services-base:8.4.0'
    compile 'com.google.android.gms:play-services-ads:8.4.0'
    compile 'com.google.android.gms:play-services-gcm:8.4.0'
}

apply plugin: 'com.google.gms.google-services'

该插件似乎可以创建 XML 和 resourcesid。

None 以上的服务或侦听器被调用。我做错了什么？

我希望你已经从这个 link

中看到了 GCM 的示例实现

你有没有像下面这样调用注册？

if (checkPlayServices()) {
        // Start IntentService to register this application with GCM.
        Intent intent = new Intent(this, RegistrationIntentService.class);
        startService(intent);
    }

拨打电话前请检查 google 播放服务。

private boolean checkPlayServices() {
    GoogleApiAvailability apiAvailability = GoogleApiAvailability.getInstance();
    int resultCode = apiAvailability.isGooglePlayServicesAvailable(this);
    if (resultCode != ConnectionResult.SUCCESS) {
        if (apiAvailability.isUserResolvableError(resultCode)) {
            apiAvailability.getErrorDialog(this, resultCode, PLAY_SERVICES_RESOLUTION_REQUEST)
                    .show();
        } else {
            Log.i(TAG, "This device is not supported.");
            finish();
        }
        return false;
    }
    return true;
}
