我已经设置了我的通知图标，但它显示了mipmap ic_launcher icon.Plese帮助我在收到通知时显示图标。

 private void addNotification() {
    NotificationCompat.Builder builder = new NotificationCompat.Builder(getActivity())
                    .setSmallIcon(R.mipmap.logo)
                    .setLargeIcon(BitmapFactory.decodeResource(getActivity().getResources(),
                            R.mipmap.logo))
                    .setContentTitle("Delivery Boy")
                    .setWhen(System.currentTimeMillis())
                    .setSound(RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION))
                    .setContentText("You have  Pending Orders");


    Intent notificationIntent = new Intent(getContext(), MainActivity.class);
    PendingIntent contentIntent = PendingIntent.getActivity(getContext(), 0, notificationIntent,
            PendingIntent.FLAG_UPDATE_CURRENT);
    builder.setContentIntent(contentIntent);

    // Add as notification
    NotificationManager manager = (NotificationManager)getActivity().getSystemService(Context.NOTIFICATION_SERVICE);
    manager.notify(0, builder.build());
}

原因：对于5.0 Lollipop“通知图标必须完全为白色”。

如果您想支持Lollipop材质图标，请为Lollipop及以上版本制作透明图标。请参阅以下https://design.google.com/icons/

以下Lollipop操作系统版本的Notification Builder实现将是：

NotificationCompat.Builder builder = new NotificationCompat.Builder(this);
if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
    builder.setSmallIcon(R.drawable.icon_transperent);
} else { 
    builder.setSmallIcon(R.drawable.icon);
}

如果要为所有操作系统版本设置彩色单个图标，则

解决方案：对于彩色图标，请使用

defaultConfig {
        applicationId "com.your.app.pkj"
        minSdkVersion xx
        targetSdkVersion 20 // < 21 (target sdk version in manifest file will be less than 21).
        versionCode x
        versionName "x.x"
    }

在app / build.gradle文件中。它会完全解决你的问题!!
