我是Android新手，并为gcm推送通知做一个演示应用程序。为什么GCM不在android设备中发送推送通知？
我开发了所有这些代码，并且GCM推送通知在我的环境中的设备上发布，但是当我在其他网络设备上测试此代码时获取注册ID，但服务器端在向云发送消息时获得不匹配的发件人ID响应。 我的代码波纹管式给出：
checkNotNull(CommonUtilities.SENDER_ID, "SENDER_ID");
GCMRegistrar.checkDevice(this);
GCMRegistrar.checkManifest(this);
setContentView(R.layout.activity_push_android);
mDisplay = (TextView) findViewById(R.id.display);
final String regId = GCMRegistrar.getRegistrationId(this);
Log.i(TAG, "registration id ===== " + regId);
if (regId.equals("")) {
GCMRegistrar.register(this, CommonUtilities.SENDER_ID);
} else {
// Device is already registered on GCM
if (GCMRegistrar.isRegisteredOnServer(this)) {
// Skips registration.
Toast.makeText(getApplicationContext(),
"Already registered with GCM", Toast.LENGTH_LONG)
.show();
} else {
// Try to register again, but not in the UI thread.
// It's also necessary to cancel the thread onDestroy(),
// hence the use of AsyncTask instead of a raw thread.
// final Context context = this;
mRegisterTask = new AsyncTask<Void, Void, Void>() {
@Override
protected Void doInBackground(Void... params) {
// Register on our server
// On server creates a new user
// ServerUtilities.register(context, name, email,
// regId);
return null;
}
@Override
protected void onPostExecute(Void result) {
mRegisterTask = null;
mDisplay.setText("ffffff " + regId);
}
};
mRegisterTask.execute(null, null, null);
}
}
// regId = GCMRegistrar.getRegistrationId(this);
mDisplay.setText("ffffff " + regId);
Log.i(TAG, "registration id =====!!!! " + regId);
}
private void checkNotNull(Object reference, String name) {
if (reference == null) {
throw new NullPointerException(getString(R.string.error_config,
name));
}
}
@Override
protected void onPause() {
super.onPause();
GCMRegistrar.unregister(this);
}
}
接收器：
public GCMIntentService() {
super(CommonUtilities.SENDER_ID);
}
private static final String TAG = "===GCMIntentService===";
@Override
protected void onRegistered(Context arg0, String registrationId) {
Log.i(TAG, "Device registered: regId = " + registrationId);
}
@Override
protected void onUnregistered(Context arg0, String arg1) {
Log.i(TAG, "unregistered = " + arg1);
}
@Override
protected void onMessage(Context arg0, Intent message) {
Bundle extras = message.getExtras();
for (String key : extras.keySet()) {
Log.d(getClass().getSimpleName(),
String.format("onMessage: %s=%s", key,
extras.getString(key)));
Toast.makeText(getApplicationContext(), "hii", Toast.LENGTH_LONG)
.show();
}
Log.i(TAG, "new message= ");
// ///////////////////
long when = System.currentTimeMillis();
NotificationManager notificationManager = (NotificationManager) context
.getSystemService(Context.NOTIFICATION_SERVICE);
Notification notification = new Notification(R.drawable.ic_launcher,
(CharSequence) message, when);
String title = context.getString(R.string.app_name);
Intent notificationIntent = new Intent(context,
PushAndroidActivity.class);
// set intent so it does not start a new activity
notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP
| Intent.FLAG_ACTIVITY_SINGLE_TOP);
PendingIntent intent = PendingIntent.getActivity(context, 0,
notificationIntent, 0);
notification.setLatestEventInfo(context, title, (CharSequence) message,
intent);
notification.flags |= Notification.FLAG_AUTO_CANCEL;
notificationManager.notify(0, notification);
}
@Override
protected void onError(Context arg0, String errorId) {
Log.i(TAG, "Received error: " + errorId);
}
@Override
protected boolean onRecoverableError(Context context, String errorId) {
return super.onRecoverableError(context, errorId);
}
}
此代码给了我一个注册ID successfully.To测试我的代码，我执行的Java类要发送消息给cloud.That java类是：
public static void main(String args[]) {
try {
Sender sender = new Sender(
"my server api");
ArrayList<String> devicesList = new ArrayList<String>();
devicesList
.add("reg id");
// devicesList.add("reg id");
// Use this line to send message without payload data
// Message message = new Message.Builder().build();
// use this line to send message with payload data
Message message = new Message.Builder()
.collapseKey("1")
.timeToLive(3)
.delayWhileIdle(true)
.addData("message",
"this text be will be seen in notification bar!!")
.build();
// Use this code to send to a single device
// Result result = sender
// .send(message,
// "APA91bGiRaramjyohc2lKjAgFGpzBwtEmI8tJC30O89C2b3IjP1CuMeU1h9LMjKhmWuZwcXZjy1eqC4cE0tWBNt61Kx_SuMF6awzIt8WNq_4AfwflaVPHQ0wYHG_UX3snjp_U-5kJkmysdRlN6T8xChB1n3DtIq98w",
// 1);
// Use this for multicast messages
MulticastResult result = sender.send(message, devicesList, 1);
sender.send(message, devicesList, 1);
System.out.println(result.toString() + "\n");
if (result.getResults() != null) {
int canonicalRegId = result.getCanonicalIds();
if (canonicalRegId != 0) {
System.out.println(canonicalRegId);
}
} else {
int error = result.getFailure();
System.out.println(error);
}
} catch (Exception e) {
e.printStackTrace();
}
}
}
现在的问题是我没有得到任何推送通知或登录猫消息。提前感谢您的帮助。 清单：

发布你的清单文件。也许广播接收器声明有什么问题 –
服务器端设置可能有问题。 –
