我的帖子请求的响应总是返回下面的错误，尽管我的设备已经注册。此外，我不知道这是否有帮助，但我正在使用android studio来部署我的应用程序。
{"multicast_id":xxxxx,"success":0,"failure":1,"canonical_ids":0,"results":[{"error":"NotRegistered"}]}
这是我在第一个活动中的代码
private GCMClientManager mPushClientManager;

@Override

mPushClientManager = new GCMClientManager(this, PROJECT_NUMBER);

@Override
public void onSuccess(String registrationId, boolean isNewRegistration) {
Toast.makeText(ChoicesActivity.this, registrationId,
Toast.LENGTH_SHORT).show();
Log.e("test", "regId " + registrationId);
// SEND async device registration to your back-end server

这是我的GCMMessageHandler

createNotification(from, message);
}
// Creates notification based on title and body received
private void createNotification(String title, String body) {
Context context = getBaseContext();
NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(context)
.setSmallIcon(R.mipmap.ic_launcher).setContentTitle(title)
.setContentText(body);
NotificationManager notificationManager = (NotificationManager) context
.getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(MESSAGE_NOTIFICATION_ID, mBuilder.build());
}
}
我的AndroidManifest.xml里面还有以下内容

这是我正在制作帖子请求的脚本
REGISTRATION_ID=xxxxxx
SERVER_KEY=xxxxx
curl --header "Authorization: key=$SERVER_KEY" --header Content-Type:"application/json" https://android.googleapis.com/gcm/send -d "{ \"data\" : {\"foo\": \"bar\"}, \"registration_ids\":[\"$REGISTRATION_ID\"] }"
答案 0 :(得分：0)
GCM回复＆＃39;未注册＆＃39;表示＆＃34;如果是NotRegistered，则应从服务器数据库中删除注册ID，因为该应用程序是从设备上卸载的，或者没有配置为接收com.google.android.c2dm.intent的广播接收器。收到意图。＆＃34;来自文档。检查从设备中卸载应用程序或在AndroidManifest中描述错误的broadcastreceiver时出现此错误的情况。您可以使用我的test gcm服务器测试GCM功能。希望，这对你有帮助。
