Android Google Cloud Messaging registration ID expired after 24 hours

I recently began working with Google Cloud Messaging for push notifications. I have an app that I have not released a signed apk for (information provided in case there is some detection of dev builds) and have not reinstalled the app in any way shape or form.
My app requests a registration ID, I store it manually while the server side is being worked on, and test with a small bit of code on the server that is set up to send push notifications. It works for the bulk of the day but the following morning I get a response "{ error: 'NotRegistered' }".
I have taken no actions to unregister the device and the app version has not changed.

This is intentional.
Registration IDs will expire after some time. Client should detect that and request another ID.
http://developer.android.com/google/gcm/client.html
As stated above, an Android app must register with GCM servers and get a registration ID before it can receive messages. A given registration ID is not guaranteed to last indefinitely, so the first thing your app should always do is check to make sure it has a valid registration ID (as shown in the code snippets above).

GCM device registration

Implicit intents with startService are not safe: Intent { act=com.google.android.c2dm.intent.REGISTRATION (has extras) } android.content.ContextWrapper.startService:494 in.demo.gcm.MainActivity$1.onClick:29 android.view.View.performClick:4438
I am getting above error,i add gcm.jar in my project but still my error not clear.
Please give me any other suggestion.
Thanks in advance.

I don't know about the error you are getting, but gcm.jar is obsolete. The recommended way to register to GCM is via the GoogleCloudMessaging.register method of the Google Play Services library.
The registration code (taken from the official GCM demo app) looks like this :
/**
* Registers the application with GCM servers asynchronously.
* <p>
* Stores the registration ID and the app versionCode in the application's
* shared preferences.
*/
private void registerInBackground() {
new AsyncTask<Void, Void, String>() {
#Override
protected String doInBackground(Void... params) {
String msg = "";
try {
if (gcm == null) {
gcm = GoogleCloudMessaging.getInstance(context);
}
regid = gcm.register(SENDER_ID);
msg = "Device registered, registration ID=" + regid;
// You should send the registration ID to your server over HTTP, so it
// can use GCM/HTTP or CCS to send messages to your app.
sendRegistrationIdToBackend();
// For this demo: we don't need to send it because the device will send
// upstream messages to a server that echo back the message using the
// 'from' address in the message.
// Persist the regID - no need to register again.
storeRegistrationId(context, regid);
} catch (IOException ex) {
msg = "Error :" + ex.getMessage();
// If there is an error, don't just keep trying to register.
// Require the user to click a button again, or perform
// exponential back-off.
}
return msg;

Android GCM: sendRegistrationIdToBackend syntax error on token void

I'm following the android GCM tutorial provided by google, and I get the following errors:
on the line:
private void sendRegistrationIdToBackend() {
// Your implementation here.
}
Syntax error on Token "Void", # expected.
Syntax error insert "enum Identifier" to complete EnumHeader.
Using, compiler 1.6
Thank you so much.
The entire function:
private void registerInBackground() {
new AsyncTask() {
#Override
protected String doInBackground(Void... params) {
String msg = "";
try {
if (gcm == null) {
gcm = GoogleCloudMessaging.getInstance(context);
}
regid = gcm.register(SENDER_ID);
msg = "Device registered, registration ID=" + regid;
// You should send the registration ID to your server over HTTP,
// so it can use GCM/HTTP or CCS to send messages to your app.
// The request to your server should be authenticated if your app
// is using accounts.
sendRegistrationIdToBackend();
// For this demo: we don't need to send it because the device
// will send upstream messages to a server that echo back the
// message using the 'from' address in the message.
// Persist the regID - no need to register again.
storeRegistrationId(context, regid);
} catch (IOException ex) {
msg = "Error :" + ex.getMessage();
// If there is an error, don't just keep trying to register.
// Require the user to click a button again, or perform
// exponential back-off.
}
return msg;
}
#Override
protected void onPostExecute(String msg) {
mDisplay.append(msg + "\n");
}
}.execute(null, null, null);
/**

* or CCS to send messages to your app. Not needed for this demo since the

*/
private void sendRegistrationIdToBackend() {
// Your implementation here.
}
}

It seems you forgot to close the registerInBackground() method.
Add } after }.execute(null, null, null);
Another way to look at it is that you put private void sendRegistrationIdToBackend() {} inside the registerInBackground() method, which is wrong.

GoogleCloudMessaging APIs Implementing GCM Client

hello i am following the official documentation of android to send the push notification as the old method is deprecated but im facing problem in implementing GCM Client
http://developer.android.com/google/gcm/client.html
the tutorial is written here, scroll down and see
private void registerInBackground()
when i write this function on my app it gives me this error
Syntax error on token "void", # expected
i have googled it and i know the error now that this method is trying to create a method inside a method but still im confused because it is the official documentation i must have done something wrong, can anybody point out plz?
here is the method on this tutorial:
private void registerInBackground() {
new AsyncTask() {
#Override
protected String doInBackground(Void... params) {
String msg = "";
try {
if (gcm == null) {
gcm = GoogleCloudMessaging.getInstance(context);
}
regid = gcm.register(SENDER_ID);
msg = "Device registered, registration ID=" + regid;
// You should send the registration ID to your server over HTTP,
// so it can use GCM/HTTP or CCS to send messages to your app.
// The request to your server should be authenticated if your app
// is using accounts.
sendRegistrationIdToBackend();
// For this demo: we don't need to send it because the device
// will send upstream messages to a server that echo back the
// message using the 'from' address in the message.
// Persist the regID - no need to register again.
storeRegistrationId(context, regid);
} catch (IOException ex) {
msg = "Error :" + ex.getMessage();
// If there is an error, don't just keep trying to register.
// Require the user to click a button again, or perform
// exponential back-off.
}
return msg;
}
#Override
protected void onPostExecute(String msg) {
mDisplay.append(msg + "\n");
}
}.execute(null, null, null);
...
/**

* or CCS to send messages to your app. Not needed for this demo since the

* using the 'from' address in the message.
*/
private void sendRegistrationIdToBackend() {
// Your implementation here.
}
}
now see that sendRegistrationIdToBackend is inside a method itself, any help plz?

here is the solution i found for it and disappointed that 33 people viewed it but nobody bother to ans anyways here is the code
private void registerInBackground() {
new AsyncTask<Void, Void, String>() {
#Override
protected String doInBackground(Void... params) {
String msg = "";
try {
if (gcm == null) {
gcm = GoogleCloudMessaging.getInstance(context);
}
regid = gcm.register(SENDER_ID);
msg = "Device registered, registration ID=" + regid;
// You should send the registration ID to your server over HTTP, so it
// can use GCM/HTTP or CCS to send messages to your app.
sendRegistrationIdToBackend();
// For this demo: we don't need to send it because the device will send
// upstream messages to a server that echo back the message using the
// 'from' address in the message.
// Persist the regID - no need to register again.
storeRegistrationId(context, regid);
} catch (IOException ex) {
msg = "Error :" + ex.getMessage();
// If there is an error, don't just keep trying to register.
// Require the user to click a button again, or perform
// exponential back-off.
}
return msg;
}
#Override
protected void onPostExecute(String msg) {
mDisplay.append(msg + "\n");
}
}.execute(null, null, null);
}

GCM AUTHENTICATION_FAILED error while getting registration id

I,m developing GCM app and recieve "error:AUTHENTICATION_FAILED". I,m using my samsung tab device.My code is below:
private void registerInBackground() {

regid = gcm.register(SENDER_ID);
Log.i(TAG, "id = :"+regid);
Log.i(TAG, "2222");
msg = "Device registered, registration ID=" + regid;
// You should send the registration ID to your server over HTTP, so it

}
i Get this msg when the control comes in postExecute function and print the "msg" variable. I searched for the error and found that this error come due to wrong password of gmail sync acount, But i checked it and my password is correct. Kindly help

add in your manifestfile:

I think you are using old GCM implementation. New GCM implementation code is available on developer site(http://developer.android.com/google/gcm/client.html). Account authentication and other type of authentication is properly handled here
