本文介绍了登录从Web服务器Android应用和保存设备registrationId的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我在Android和Web服务很新。我试图登录到我的Android应用程序，其中的数据是从Web服务来，并在同一时间，我想注册的Web服务器数据库使用GCM Android设备的ID。直到现在我迄今所做的。如果可能的话，请给我你的时间资产我。
I am very new in android and web services. I am trying to login into my android app where the data is coming from web service and at the same time I want to register the Id of android device using GCM in web server database.

推荐答案
您使用的是注册到GCM，这是pcated德$ P $的老路。注册的新方法只需要调用 GoogleCloudMessaing.register 方法，它是阻塞，因此，你不必得到的结果在意向服务。
You are using the old way of registering to GCM, which is deprecated. The new way of registering simply requires calling GoogleCloudMessaing.register method, which is blocking, and therefore you don't have to get the result in the intent service.
您可以按照<一个href=\"http://$c$c.google.com/p/gcm/source/browse/gcm-client/GcmClient/src/main/java/com/google/android/gcm/demo/app/DemoActivity.java\"相对=nofollow>如果您希望使用新的方式正式GCM演示程序。
如果您希望继续使用旧的方式，它仍然可以工作，但你必须做出一些修正：
If you wish to stick with the old way, it can still work, but you'll have to make some fixes :
如果您的应用程序的软件包名称为 com.example.appname ，清单应始终如一地使用它。因此，与其：
If your app's package name is com.example.appname, the manifest should use it consistently. Therefore, instead of :
<permission
android:name="com.example.clipme.permission.C2D_MESSAGE"
android:protectionLevel="signature" />
<uses-permission android:name="com.example.appname.permission.C2D_MESSAGE" />
你应该有
<permission
android:name="com.example.appname.permission.C2D_MESSAGE"
android:protectionLevel="signature" />
<uses-permission android:name="com.example.appname.permission.C2D_MESSAGE" />
此外，你的意图服务类 com.example.appname.gcm.GCMIntentService 是在包 com.example.appname.gcm ，但您正在使用的广播接收机 - com.google.android.gcm.GCMBroadcastReceiver - 默认主包中寻找它（ com.example.appname.GCMIntentService ）。因此，它没有找到它。您shuold无论是服务类移动到主包或覆盖广播接收器类来更改它希望找到的意图服务类。
In addition, your intent service class com.example.appname.gcm.GCMIntentService is in the package com.example.appname.gcm, but the broadcast receiver you are using - com.google.android.gcm.GCMBroadcastReceiver - looks for it by default in the main package (com.example.appname.GCMIntentService). Therefore it doesn't find it. You shuold either move the service class to the main package or override the broadcast receiver class to change where it expects to find the intent service class.
