如何使用GCM在Android中发送大小图像作为推送通知

Question

I have written a php code to send a push notification to android mobile using GCM server. Its working fine. Now I want to send large and small image as a push notification. How can I do that Here is my code.

<?php
// API access key from Google API's Console
define( 'API_ACCESS_KEY', 'YOUR-API-ACCESS-KEY-GOES-HERE' );
$registrationIds = array( $_GET['id'] );
// prep the bundle
$msg = array
(
    'message'   => 'here is a message. message',
    'title'     => 'This is a title. title',
    'subtitle'  => 'This is a subtitle. subtitle',
    'tickerText'    => 'Ticker text here...Ticker text here...Ticker text here',
    'vibrate'   => 1,
    'sound'     => 1,
    'largeIcon' => 'https://cdn4.iconfinder.com/data/icons/iconsimple-logotypes/512/github-512.png',
    'smallIcon' => 'small_icon'
);
$fields = array
(
    'registration_ids'  => $registrationIds,
    'data'          => $msg
);

$headers = array
(
    'Authorization: key=' . API_ACCESS_KEY,
    'Content-Type: application/json'
);

$ch = curl_init();
curl_setopt( $ch,CURLOPT_URL, 'https://android.googleapis.com/gcm/send' );
curl_setopt( $ch,CURLOPT_POST, true );
curl_setopt( $ch,CURLOPT_HTTPHEADER, $headers );
curl_setopt( $ch,CURLOPT_RETURNTRANSFER, true );
curl_setopt( $ch,CURLOPT_SSL_VERIFYPEER, false );
curl_setopt( $ch,CURLOPT_POSTFIELDS, json_encode( $fields ) );
$result = curl_exec($ch );
curl_close( $ch );
echo $result;
?>

Answer 1

I would suggest you to use OneSignal

I'm using this and you would get much more in this and your large image and small image problem can be solved from here and it's totally free of cost . I hope it would help you

You need to download the image specified in the 'largeIcon' parameter as a bitmap and set it in the notification. Here is an example of how it is done with Glide Image loading library.

In your GCMListener service's onMessageReceived do the following

@Override
public void onMessageReceived(String from, Bundle data) {
    String largeIconUrl = data.getString("largeIcon"); // the way you obtain this may differ
    Bitmap largeBitmap = null;
    try {
       largeBitmap = Glide
                      .with(this)
                      .load(largeIconUrl)
                      .asBitmap()
                      .into(100, 100) // Width and height
                      .get();
    } catch (Exception ex){
        // image download from the url failed
    }

    if(largeBitmap != null){
        Intent intent = new Intent(this, MainActivity.class); 
        intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP); 
        PendingIntent pendingIntent = PendingIntent.getActivity(this, 0 /* Request code */, intent, PendingIntent.FLAG_ONE_SHOT); 

        Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION); 
        NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this) 
                                                            .setSmallIcon(R.drawable.ic_launcher) 
                                                            .setContentTitle("Your title goes here") 
                                                            .setContentText("Your description goes here") 
                                                            .setAutoCancel(true) 
                                                            .setSound(defaultSoundUri) 
                                                            .setContentIntent(pendingIntent) 
                                                            .setLargeIcon(largeBitmap); 

        NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE); 

        notificationManager.notify(0 /* ID of notification */, notificationBuilder.build()); 
    }
}
