android - Google Cloud Messaging を Xamarin for Android に登録する際の SERVICE_NOT_AVAILABLE

Question

Xamarin で GCM を使用する Android アプリを作成しています。Xamarin チームのこのガイドと、Google チームのこのガイドに従いました。

Gcm の Xamarin バージョンを実装した後、BroadcaseReceiver.OnReceive で何も受信しませんでした。これがマニフェストとブロードキャストレシーバーです

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android" 
          android:installLocation="auto" 
          package="com.pushtest.droid" 
          android:versionCode="1" 
          android:versionName="1">

  <uses-sdk android:minSdkVersion="8" android:targetSdkVersion="15" />

  <uses-permission android:name="com.google.android.c2dm.permission.RECEIVE" />
  <uses-permission android:name="android.permission.GET_ACCOUNTS" />
  <uses-permission android:name="android.permission.INTERNET" />
  <uses-permission android:name="android.permission.WAKE_LOCK" />

  <permission android:name="com.pushtest.droid.permission.C2D_MESSAGE" android:protectionLevel="signature"/>
  <uses-permission android:name="com.pushtest.droid.permission.C2D_MESSAGE" />

  <application android:label="push droid"/>
</manifest>

ブロードキャストレシーバー:

[BroadcastReceiver(Permission = "com.google.android.c2dm.permission.SEND")]
    [IntentFilter(new[] {"com.google.android.c2dm.intent.RECEIVE"}, Categories = new[] {"com.pushtest.droid"})]
    [IntentFilter(new[] {"com.google.android.c2dm.intent.REGISTRATION"}, Categories = new[] {"com.pushtest.droid"})]
    [IntentFilter(new[] {"com.google.android.gcm.intent.RETRY"}, Categories = new[] {"com.pushtest.droid"})]
    public class MyGcmBroadcastReceiver : BroadcastReceiver
    {
        public override void OnReceive(Context context, Intent intent)
        {
            System.Diagnostics.Debug.WriteLine("MyGcmBroadcastReceiver.OnReceive");
            if (intent.Action == "com.google.android.c2dm.intent.REGISTRATION")
            {
                var registrationId = intent.GetStringExtra("registration_id");
                var error = intent.GetStringExtra("error");
                var unregistered = intent.GetStringExtra("unregistered");
                System.Diagnostics.Debug.WriteLine("!!!! Registration status |R: {0}|E: {1}|U: {2}", registrationId, error, unregistered);
            }
            else if (intent.Action == "com.google.android.c2dm.intent.RECEIVE")
            {
                System.Diagnostics.Debug.WriteLine("!!!! Push Received: |TBD|");
            }
        }
    }

インテントを開始したとき、何も得られませんでした-エラーもデバッグ情報も結果もありません:

private void RegisterForGcm(Context context)
        {
            const string SenderId = "PROJECT_ID_FROM_GOOGLE_CONSOLE";
            var appExtra = PendingIntent.GetBroadcast(context, 0, new Intent(), 0);

            var intent = new Intent("com.google.android.c2dm.intent.REGISTER");
            intent.PutExtra("app", appExtra);
            intent.PutExtra("sender", SenderId);
            context.StartService(intent);
        }

次に、Googleのガイドが最終的にエラー= "SERVICE_NOT_AVAILABLE"で登録応答を取得したと考えました:

余分な文字列はありませんでした (registration_id はありません)。デバッグ情報：！！！！登録状況 |R: |E: SERVICE_NOT_AVAILABLE|U:

これが私のマニフェストとBroadcastReceiverです(インテントスタートは同じです):

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android" 
          android:installLocation="auto" 
          package="com.pushtest.droid" 
          android:versionCode="1" 
          android:versionName="1">

  <uses-sdk android:minSdkVersion="8" android:targetSdkVersion="15" />

  <uses-permission android:name="com.google.android.c2dm.permission.RECEIVE" />
  <uses-permission android:name="android.permission.GET_ACCOUNTS" />
  <uses-permission android:name="android.permission.INTERNET" />
  <uses-permission android:name="android.permission.WAKE_LOCK" />

  <permission android:name="com.pushtest.droid.permission.C2D_MESSAGE" android:protectionLevel="signature"/>
  <uses-permission android:name="com.pushtest.droid.permission.C2D_MESSAGE" />

  <application android:label="push droid">
    <receiver android:name="com.pushtest.droid.MyGcmBroadcastReceiver"
              android:permission="com.google.android.c2dm.permission.SEND">
      <intent-filter>
        <action android:name="com.google.android.c2dm.intent.RECEIVE" />
        <action android:name="com.google.android.c2dm.intent.REGISTRATION" />
        <action android:name="com.google.android.gcm.intent.RETRY" />

        <category android:name="com.pushtest.droid" />
      </intent-filter>
    </receiver>
  </application>
</manifest>

および BroadcastReceiver (属性なし)

 public class MyGcmBroadcastReceiver : BroadcastReceiver
    {
        public override void OnReceive(Context context, Intent intent)
        {
            System.Diagnostics.Debug.WriteLine("MyGcmBroadcastReceiver.OnReceive");
            if (intent.Action == "com.google.android.c2dm.intent.REGISTRATION")
            {
                var registrationId = intent.GetStringExtra("registration_id");
                var error = intent.GetStringExtra("error");
                var unregistered = intent.GetStringExtra("unregistered");
                System.Diagnostics.Debug.WriteLine("!!!! Registration status |R: {0}|E: {1}|U: {2}", registrationId, error, unregistered);
            }
            else if (intent.Action == "com.google.android.c2dm.intent.RECEIVE")
            {
                System.Diagnostics.Debug.WriteLine("!!!! Push Received: |TBD|");
            }
        }
    }

ここでのテスト例: https://dl.dropboxusercontent.com/u/19503836/pushtest-issue.zip

Android 2.3.6 デバイスでこのコードを試していました。

サービス [IntentService ] クラスを作成していません。サービスを開始していますが、それを作成していません。BroadCastReceiver は次のようになります。

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

using Android.App;
using Android.Content;
using Android.OS;
using Android.Runtime;
using Android.Views;
using Android.Widget;
namespace hellomultiscreen
{

    public class MyGCMBroadcastReceiver : BroadcastReceiver
    {

        const string TAG = "PushHandlerBroadcastReceiver";
        public override void OnReceive(Context context, Intent intent)
        {

            MyIntentService.RunIntentInService(context, intent);
            SetResult(Result.Ok, null, null);
            Toast.MakeText(context, "Received Message!", ToastLength.Short).Show();
        }
    }

PushSharpは非常にうまく機能するため、私は独自のプッシュ技術を構築しようとしたことは一度もありません。彼はモノドロイドとモノタッチの例を実際のコードと共に持っています。私たちは常にそれを仕事で使用してきましたが、いくつかの古いバグが修正されたことを除けば、ライブラリはしっかりしています。

私は自分のアプリが生成するマニフェストを見てきましたが、あなたのものにはないものがあります。独自のサービスを構築することを主張する場合は、少なくとも彼のコードを見て、彼がどのようにそれを行っているかを確認してください。
