Please help me out if you can. I've been trying to implement a basic gcm setup. On the server side I'm using php code from the top answer over here - GCM with PHP (Google Cloud Messaging) And on the client side I've followed Google's GCM tutorial. The whole thing is working fine on my Nexus 4, but it won't work on the two pre 4.0.4 devices i've tried. One is htc one v running 4.0.3 and the other is sony ericsson running 2.3.4. It could be something about the pre 4.0.4 devices thing, but they are registering successfully and giving me regids properly. They just won't receive any messages,though the gcm server is receiving them and sending back message ids with success.. even the broadcast receiver doesn't fire. If you have any idea why this is happening could you help me out please? Both devices have registered google accounts by the way.
Here is my manifest file.

Here is the php implementation. It's using static regids right now.. i'm getting those by dumping them in the log from the app. It's working fine i think because i'm receiving messages properly on my nexus 4. This gives me three message ids when executed.
<?php
// Replace with real BROWSER API key from Google APIs
$apiKey = "myapikey";
// Replace with real client registration IDs
$registrationIDs = array( "regid1", "regid2" , "regid3" );
// Message to be sent
$message = "Hello";
// Set POST variables
$url = 'https://android.googleapis.com/gcm/send';
$fields = array(
'registration_ids' => $registrationIDs,
'data' => array( "message" => $message ),
);
$headers = array(
'Authorization: key=' . $apiKey,
'Content-Type: application/json'
);
// Open connection
$ch = curl_init();
echo "here";
// Set the url, number of POST vars, POST data
curl_setopt( $ch, CURLOPT_URL, $url );
curl_setopt( $ch, CURLOPT_POST, true );
curl_setopt( $ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt( $ch, CURLOPT_RETURNTRANSFER, true );
curl_setopt( $ch, CURLOPT_POSTFIELDS, json_encode( $fields ) );
// Execute post
$result = curl_exec($ch);
curl_close($ch);
if(curl_errno($ch)){ echo 'Curl error: ' . curl_error($ch);}
echo $result;
?>
This is my mainactivity.

This is the broadcast receiver. This never gets called in the two devices, because the log doesn't show anything.
