Question

在AndroidManifest.xml中，我定义了以下组件

<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="com.admin.freddyspeaks" />
            </intent-filter>
        </receiver>

        <service
            android:name="com.admin.services.NodeGcmListenerService"
            android:exported="false">
            <intent-filter>
                <action android:name="com.google.android.c2dm.intent.RECEIVE" />
            </intent-filter>
        </service>
        <service
            android:name="com.admin.services.MyInstanceIDListenerService"
            android:exported="false">
            <intent-filter>
                <action android:name="com.google.android.gms.iid.InstanceID" />
            </intent-filter>
        </service>
        <service
            android:name="com.admin.services.RegistrationIntentService"
            android:exported="false" />

NodeGcmListenerService.java

class NodeGcmListenerService extends GcmListenerService {

    @Override
    public void onMessageReceived(String from, Bundle data) {
        String message = data.getString("message");
        Log.d("", "From: " + from);
        Log.d("", "Message: " + message);
        //Set data
    }

}

MyInstanceIDListenerService.java

public class MyInstanceIDListenerService extends InstanceIDListenerService {

    @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);
    }
}

这是RegistrationIntentService.java

public class RegistrationIntentService extends IntentService {

    private static final String TAG = "RegIntentService";

    public RegistrationIntentService() {
        super(TAG);
    }

    @Override
    public void onHandleIntent(Intent intent) {
        try {
            InstanceID instanceID = InstanceID.getInstance(this);
            String token = instanceID.getToken(getString(R.string.gcm_defaultSenderId),
                    GoogleCloudMessaging.INSTANCE_ID_SCOPE, null);
            sendRegistrationToServer(token);
        }
        catch(IOException e) {
            Log.e(TAG,"Unable to register device",e);
        }
    }
}

当我从服务器发送消息并且应用程序强制关闭时，不会调用NodeGcmListenerService onMessage方法

Answer 1

当应用程序强行关闭时，
GCMListenerService不会被调用

当应用程序被强制关闭时，它的字面意思是。没有正常的生命周期保证。您的应用程序行为不端，现在立即被击落。系统将清理剩余的，但你的代码无处可做。

PS：在崩溃后检查堆栈跟踪。

应用程序关闭时，不会调用GCMListenerService
