更新:我修复了以下代码中的问题,因此这是一个很好的基本工作示例,说明如何使用GCM
所以,我正在尝试在我的应用中实施Android GCM
。以下是我添加到清单中的相关部分:
<uses-sdk android:minSdkVersion="8" android:targetSdkVersion="20" />
<permission
android:name=".permission.C2D_MESSAGE"
android:protectionLevel="signature" />
<uses-permission android:name="com.google.android.c2dm.permission.RECEIVE" />
<uses-permission android:name=".permission.C2D_MESSAGE" />
<uses-permission android:name="android.permission.WAKE_LOCK"/>
<uses-permission android:name="android.permission.GET_ACCOUNTS"/>
...
<receiver
android:name="com.google.android.gcm.GCMBroadcastReceiver"
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" />
<category android:name="com.badbob.app.gmctestapp" />
</intent-filter>
</receiver>
<service android:name=".GCMIntentService" />
我已将以下代码添加到我的主要活动的onCreate中:
GCMRegistrar.checkDevice( this );
GCMRegistrar.checkManifest( this );
final String regId = GCMRegistrar.getRegistrationId( this );
if( regId.equals( "" ) ) {
GCMRegistrar.register( this, GCM_SENDER_ID );
}
else {
Log.v( LOG_TAG, "Already registered" );
}
我也像这样创建了GCMIntenetService
类:
public class GCMIntentService extends GCMBaseIntentService {
private static final String LOG_TAG = "GetAClue::GCMIntentService";
public GCMIntentService() {
super( GCM_SENDER_ID );
// TODO Auto-generated constructor stub
Log.i( LOG_TAG, "GCMIntentService constructor called" );
}
@Override
protected void onError( Context arg0, String errorId ) {
// TODO Auto-generated method stub
Log.i( LOG_TAG, "GCMIntentService onError called: " + errorId );
}
@Override
protected void onMessage( Context arg0, Intent intent ) {
// TODO Auto-generated method stub
Log.i( LOG_TAG, "GCMIntentService onMessage called" );
Log.i( LOG_TAG, "Message is: " + intent.getStringExtra( "message" ) );
}
@Override
protected void onRegistered( Context arg0, String registrationId ) {
// TODO Auto-generated method stub
Log.i( LOG_TAG, "GCMIntentService onRegistered called" );
Log.i( LOG_TAG, "Registration id is: " + registrationId );
}
@Override
protected void onUnregistered( Context arg0, String registrationId ) {
// TODO Auto-generated method stub
Log.i( LOG_TAG, "GCMIntentService onUnregistered called" );
Log.i( LOG_TAG, "Registration id is: " + registrationId );
}
}
当我运行此操作时,我会在 LogCat :
中获得此信息07-11 11:28:46.340: V/GCMRegistrar(27435): Registering receiver
07-11 11:28:46.370: D/GCMRegistrar(27435): resetting backoff for com.badbob.app.getacluebeta
07-11 11:28:46.380: V/GCMRegistrar(27435): Registering app com.badbob.app.getacluebeta of senders 128205395388
根据我从其他帖子中收集到的内容,我应该在LogCat
中获得注册ID,但我不是。onRegistered()
中的GCMIntentService
永远不会被调用。那么我是什么?做错了?
答案 0 :(得分:18)
这是不正确的
protected GCMIntentService( String senderId ) {
super(senderId);}
正如文档中所述。你必须为GCMIntentService声明一个PUBLIC,NO ARGUMENT构造函数。否则,GCMIntentService无法由后台意图服务正确实例化。
public GCMIntentService(){
super(senderID);}
senderID可以是硬编码的常量字符串,因为它不再随新的GCM而改变。 使用正确的senderID也非常重要。 24小时足以让你自己活跃,所以如果我的上述解决方案无效,你使用的是不正确的senderID。其他一切看起来都很棒。
当您浏览Google API访问权限页时,senderID位于您的网络浏览器的网址中。单击GCM,浏览器URL中将显示一个12位数字。这是正确使用的密钥。不是你的API密钥。这是在App服务器端使用的。

我也有这个恼人的错误,直到现在。问题是,我在另一个包中声明了intentservice ...即使我在android清单中声明了名称并且没有放置classnotfound异常......也没有找到任何错误......所以我确保了intentservice在根包中。
答案 2 :(得分:3)
我认为您在代码中遇到了一些问题。
您应该在清单文件中注册您自己的广播接收器,该接收器将触发<service android:name=".GCMIntentService" />
。
因此,你必须做我写下面的事情。
接收方必须声明为:
<receiver
android:name="your.package.name.YourBroadCastReceiver"
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" />
</intent-filter>
将启动该服务的广播接收器。
public class YourBroadCastReceiver extends BroadcastReceiver {
@Override
public final void onReceive(Context context, Intent intent) {
GCMIntentService .runIntentInService(context, intent);
setResult(Activity.RESULT_OK, null, null);
}
}
我建议你看看官方GCM documentation,你可以在那里找到一个很好的例子。
并且...不要忘记在主Google API控制台页面中启用 Google Cloud Messaging 服务。
让我知道它是否有帮助!

在这里,我已经为如何从头开始获取RegID和通知编写了几个步骤
您可以在以下网址链接中找到完整的教程
代码剪辑以获取注册ID(推送通知的设备令牌)。
为GCM配置项目
要在我们的项目中启用GCM,我们需要在清单文件中添加一些权限 转到AndroidManifest.xml并添加以下代码 添加权限
<uses-permission android:name="android.permission.INTERNET”/>
<uses-permission android:name="android.permission.GET_ACCOUNTS" />
<uses-permission android:name="android.permission.WAKE_LOCK" />
<uses-permission android:name="android.permission.VIBRATE" />
<uses-permission android:name=“.permission.RECEIVE" />
<uses-permission android:name=“<your_package_name_here>.permission.C2D_MESSAGE" />
<permission android:name=“<your_package_name_here>.permission.C2D_MESSAGE"
android:protectionLevel="signature" />
添加GCM广播接收器声明
在应用程序标记中添加GCM广播接收者声明
<application
<receiver
android:name=".GcmBroadcastReceiver"
android:permission="com.google.android.c2dm.permission.SEND" ]]>
<intent-filter]]>
<action android:name="com.google.android.c2dm.intent.RECEIVE" />
<category android:name="" />
</intent-filter]]>
</receiver]]>
<application/>
添加GCM Servie声明
<application
<service android:name=".GcmIntentService" />
<application/>
现在转到启动/启动活动
添加常量和类变量
private final static int PLAY_SERVICES_RESOLUTION_REQUEST = 9000;
public static final String EXTRA_MESSAGE = "message";
public static final String PROPERTY_REG_ID = "registration_id";
private static final String PROPERTY_APP_VERSION = "appVersion";
private final static String TAG = "LaunchActivity";
protected String SENDER_ID = "Your_sender_id";
private GoogleCloudMessaging gcm =null;
private String regid = null;
private Context context= null;
更新OnCreate和OnResume方法
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_launch);
context = getApplicationContext();
if (checkPlayServices())
{
gcm = GoogleCloudMessaging.getInstance(this);
regid = getRegistrationId(context);
if (regid.isEmpty())
{
registerInBackground();
}
else
{
Log.d(TAG, "No valid Google Play Services APK found.");
}
}
}
@Override protected void onResume()
{
super.onResume(); checkPlayServices();
}
# Implement GCM Required methods (Add below methods in LaunchActivity)
private boolean checkPlayServices() {
int resultCode = GooglePlayServicesUtil.isGooglePlayServicesAvailable(this);
if (resultCode != ConnectionResult.SUCCESS) {
if (GooglePlayServicesUtil.isUserRecoverableError(resultCode)) {
GooglePlayServicesUtil.getErrorDialog(resultCode, this,
PLAY_SERVICES_RESOLUTION_REQUEST).show();
} else {
Log.d(TAG, "This device is not supported - Google Play Services.");
finish();
}
return false;
}
return true;
}
private String getRegistrationId(Context context)
{
final SharedPreferences prefs = getGCMPreferences(context);
String registrationId = prefs.getString(PROPERTY_REG_ID, "");
if (registrationId.isEmpty()) {
Log.d(TAG, "Registration ID not found.");
return "";
}
int registeredVersion = prefs.getInt(PROPERTY_APP_VERSION, Integer.MIN_VALUE);
int currentVersion = getAppVersion(context);
if (registeredVersion != currentVersion) {
Log.d(TAG, "App version changed.");
return "";
}
return registrationId;
}
private SharedPreferences getGCMPreferences(Context context)
{
return getSharedPreferences(LaunchActivity.class.getSimpleName(),
Context.MODE_PRIVATE);
}
private static int getAppVersion(Context context)
{
try
{
PackageInfo packageInfo = context.getPackageManager()
.getPackageInfo(context.getPackageName(), 0);
return packageInfo.versionCode;
}
catch (NameNotFoundException e)
{
throw new RuntimeException("Could not get package name: " + e);
}
}
private void registerInBackground()
{ new AsyncTask() {
Override
protected Object doInBackground(Object... params)
{
String msg = "";
try
{
if (gcm == null)
{
gcm = GoogleCloudMessaging.getInstance(context);
}
regid = gcm.register(SENDER_ID); Log.d(TAG, "########################################");
Log.d(TAG, "Current Device's Registration ID is: "+msg);
}
catch (IOException ex)
{
msg = "Error :" + ex.getMessage();
}
return null;
} protected void onPostExecute(Object result)
{ //to do here };
}.execute(null, null, null);
}
注意:请存储REGISTRATION_KEY,向GCM发送PN消息非常重要 同时保留在我的所有设备中都是唯一的,通过使用此功能,只有GCM会发送推送通知。
添加GCM广播接收器类
由于我们已在Manifest文件中声明了“GcmBroadcastReceiver.java”,因此我们创建此类 以这种方式更新接收器类代码
public class GcmBroadcastReceiver extends WakefulBroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent)
{ ComponentName comp = new ComponentName(context.getPackageName(),
GcmIntentService.class.getName()); startWakefulService(context, (intent.setComponent(comp)));
setResultCode(Activity.RESULT_OK);
Toast.makeText(context, “wow!! received new push notification", Toast.LENGTH_LONG).show();
}
}
添加GCM服务类
由于我们已在Manifest文件中声明了“GcmBroadcastReceiver.java”,因此我们创建此类 以这种方式更新接收器类代码
public class GcmIntentService extends IntentService
{ public static final int NOTIFICATION_ID = 1; private NotificationManager mNotificationManager; private final static String TAG = "GcmIntentService"; public GcmIntentService() {
super("GcmIntentService");
} @Override
protected void onHandleIntent(Intent intent) {
Bundle extras = intent.getExtras();
Log.d(TAG, "Notification Data Json :" + extras.getString("message"));
GoogleCloudMessaging gcm = GoogleCloudMessaging.getInstance(this);
String messageType = gcm.getMessageType(intent); if (!extras.isEmpty()) { if (GoogleCloudMessaging.MESSAGE_TYPE_SEND_ERROR
.equals(messageType)) {
sendNotification("Send error: " + extras.toString());
} else if (GoogleCloudMessaging.MESSAGE_TYPE_DELETED
.equals(messageType)) {
sendNotification("Deleted messages on server: "
+ extras.toString()); // If it's a regular GCM message, do some work.
} else if (GoogleCloudMessaging.MESSAGE_TYPE_MESSAGE
.equals(messageType)) {
// This loop represents the service doing some work.
for (int i = 0; i < 5; i++) {
Log.d(TAG," Working... " + (i + 1) + "/5 @ "
+ SystemClock.elapsedRealtime()); try {
Thread.sleep(5000);
} catch (InterruptedException e) {
}
}
Log.i(TAG, "Completed work @ " + SystemClock.elapsedRealtime());
sendNotification(extras.getString("message"));
}
} // Release the wake lock provided by the WakefulBroadcastReceiver.
GcmBroadcastReceiver.completeWakefulIntent(intent);
} // Put the message into a notification and post it.
// This is just one simple example of what you might choose to do with
// a GCM message.
private void sendNotification(String msg) { mNotificationManager = (NotificationManager) this
.getSystemService(Context.NOTIFICATION_SERVICE);
PendingIntent contentIntent = PendingIntent.getActivity(this, 0, new Intent(this, LaunchActivity.class), 0);
NotificationCompat.Builder mBuilder = new NotificationCompat.Builder( this)
.setSmallIcon(R.drawable.icon)
.setContentTitle("Ocutag Snap")
.setStyle(new NotificationCompat.BigTextStyle().bigText(msg))
.setContentText(msg)
.setDefaults(Notification.DEFAULT_SOUND | Notification.DEFAULT_VIBRATE);
mBuilder.setContentIntent(contentIntent); mNotificationManager.notify(NOTIFICATION_ID, mBuilder.build());
}
}
答案 5 :(得分:0)
不确定这是否与您的具体问题有关,但是,我遇到了同样的问题。据我所知,一切都设置正确,但onRegistered()
处理程序从未被调用过。
我将标准onCreate()
,onStart()
和onDestroy()
服务方法作为GCMIntentService类的一部分。一旦我删除它们,就会按预期调用处理程序。
我的假设是,通过重写这些方法,我正在绕过所需的代码初始化。
答案 6 :(得分:0)
在阅读ClouDeveloper的帖子后,我删除了onCreate()
,onDestroy()
和其他 onXXX()回调方法。此外,我使用GCMIntentService.onRegistered(Context, regId)
调用regId
。
谢谢ClouDeveloper!

您还需要在GCMBaseIntentService.onRegistered()回调中注册您的应用服务器。否则,您将无法发送应用消息。
您应该结帐Google's GCM demo client,因为它提供了包含所有正确代码的工作示例。我们还在github上有一个工作样本:airbop-client。它提供了一个稍微更完整的示例,因为它与应用程序服务器进行了工作交互,这对于启用GCM的应用程序是必需的。它适用于AirBop服务器(我帮助创建),最多可免费提供1000台设备。
答案 8 :(得分:0)
如果您没有收到注册的响应,其中一个主要原因是您的清单文件配置不正确 - 尤其是在{{1}中提供“package_name”(您的应用包名称如com.xxx.yyy) }和<permission>
正确。
