我正在进行GCM自定义，我正在尝试获取图像并希望设置通知，但是当尝试发送通知时它会在我的logcat中给出错误，我能够在我的logcat中正确地获取消息但是图像没有得到
错误

您无法使用setSmallIcon()来设置互联网上的图片。 setSmallIcon应该指向资源中的一个图像drawable（例如：R.drawable.my_app_icon）。要从其他地方设置图片，您需要使用setLargeIcon()。此方法接受位图，因此您应将指定的Url中的图像作为位图下载，然后将其设置为setLargeIcon()方法

您无法从网址获取图片 你试图从它如何获得它？
首先从url下载它，然后给位图通知。尝试以下代码
<强>更新
添加了使用位图生成通知的代码。
Bitmap remote_picture = HTTPWebRequest.getImageForNotification(ImageUrl);
// Create the style object with BigPictureStyle subclass.
NotificationCompat.BigPictureStyle notiStyle = new NotificationCompat.BigPictureStyle();
notiStyle.setBigContentTitle(getResources().getString(R.string.app_name));
notiStyle.setSummaryText(Message);
notiStyle.bigPicture(remote_picture);
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
.setSmallIcon(R.mipmap.ic_launcher)
.setColor(AppConfig.getContext().getResources().getColor(R.color.white))
.setAutoCancel(true)
.setContentIntent(intent)
.setContentTitle(getResources().getString(R.string.app_name))
.setContentText(Message)
.setDefaults(Notification.DEFAULT_SOUND)
.setLargeIcon(notificationLargeIconBitmap)
.setWhen(System.currentTimeMillis())
.setStyle(notiStyle);
notificationManager.notify(NotificationID, notificationBuilder.build());

这是这些行的标语整数imgs = Integer.parseInt（img）; 你传递一个没有任何int值的字符串，所以你得到NumberFormatException
尝试这样做
private void sendNotification(String message,String img) {
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);
// Integer imgs=Integer.parseInt(img);
if (img != null)
new DownloadImage().execute(img);
}
public class DownloadImage extends AsyncTask<String, Context, Bitmap> {
Bitmap remote_picture = null;
@Override
protected Bitmap doInBackground(String... URL) {
try {
remote_picture = BitmapFactory.decodeStream(
(InputStream) new URL(URL[0]).getContent());
} catch (IOException e) {
e.printStackTrace();
}
return remote_picture;
}
@Override
protected void onPostExecute(Bitmap result) {
if (result != null)
Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
.setSmallIcon(imgs)
.setContentTitle("New Product Added")
.setContentText(message)
.setAutoCancel(true)
.setSound(defaultSoundUri)
.setContentIntent(pendingIntent);
NotificationManager notificationManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(0 /* ID of notification */, notificationBuilder.build());
}
}

你可以像这样创建通知
NotificationCompat.BigPictureStyle notiStyle = new
NotificationCompat.BigPictureStyle();
notiStyle.setBigContentTitle(getTitle(bundle));
notiStyle.setSummaryText(getMessage(bundle));
notiStyle.bigPicture(bitMap);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent pendingIntent = PendingIntent.getActivity(context, (int) System.currentTimeMillis() /* Request code */, intent,
PendingIntent.FLAG_ONE_SHOT);
Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(context)
.setSmallIcon(getsmallIcon())
.setAutoCancel(true)
.setStyle(notiStyle)
.setContentTitle(getTitle(bundle))
.setContentText(getMessage(bundle))
.setLargeIcon(BitmapFactory.decodeResource(context.getResources(), R.drawable.app_icon))
.setSound(defaultSoundUri)
.setContentIntent(pendingIntent);
NotificationManager notificationManager =
(NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify((int)System.currentTimeMillis(), notificationBuilder.build());
