AWS SNS中的參數無效Android應用程序

我已將AWS SNS API集成到我的Android應用程序中。當我打開我的設備上的應用程序，我得到這個錯誤日誌：AWS SNS中的參數無效Android應用程序

日誌中的代碼行是那些線： PushManager.java:251（整體法）

public void subscribeToTopic(final SnsTopic topic) { 
    final SubscribeRequest request = new SubscribeRequest(); 
    request.setEndpoint(endpointArn); 
    request.setTopicArn(topic.getTopicArn()); 
    request.setProtocol(SNS_PROTOCOL_APPLICATION); 
    /* Line 251 -> */ final SubscribeResult result = sns.subscribe(request); 

    // update topic and save subscription in shared preferences 
    final String subscriptionArn = result.getSubscriptionArn(); 
    topic.setSubscriptionArn(subscriptionArn); 
    sharedPreferences.edit().putString(topic.getTopicArn(), subscriptionArn).apply(); 
}

MainActivity.java:50

pushManager.subscribeToTopic(pushManager.getDefaultTopic());

我沒有真正意識到我的應用程序中的無效參數是什麼，所以你可以幫我嗎？

根據日誌，無效參數是端點。
爲了讓你能做的終點......

final CreatePlatformEndpointRequest request = new CreatePlatformEndpointRequest(); 
    request.setPlatformApplicationArn(platformApplicationArn); 
    request.setToken(gcmToken); 
    final CreatePlatformEndpointResult result = snsClient.createPlatformEndpoint(request);

端點可以通過檢索：

result.getEndpointArn();

我沒有任何變量的推移名字'gcmToken'或'snsClient'在我的應用程序。你能幫我解決嗎？還是有另一種方法來檢索端點ARN？ –

對不起，snsClient == sns 和gcmToken可以通過檢索： gcmToken = instanceID.getToken（gcmSenderID，GoogleCloudMessaging.INSTANCE_ID_SCOPE）; ...其中instanceID是InstanceID對象（com.google.android.gms.iid.InstanceID） –

好的，我已經將它添加到了我的代碼中，但現在我得到了這個錯誤日誌：''null'at'token'未能滿足限制：成員不能爲空。你也許知道我爲什麼得到這個錯誤以及如何解決它？我會在幾分鐘後發佈完整的日誌。 –
