The notifications that generate appear with gray background which makes it difficult to read the news:
NotificationCompat.Builder builder = new NotificationCompat.Builder(this);
builder.setTicker("Ticker Texto");
builder.setContentTitle(" notificação");
builder.setContentText("Você tem uma nova notícia");
builder.setSmallIcon(R.drawable.icone);
builder.setLargeIcon(BitmapFactory.decodeResource(getResources(), R.drawable.icone));
builder.setContentIntent(p);
Notification n = builder.build();
n.vibrate = new long[]{150, 300, 150, 600};
n.flags = Notification.FLAG_AUTO_CANCEL;
...
Why is the background appearing gray?
