Android Setting Icon To Notification Builder

Question

I am setting the required drawable to Notification.Builder but it says cannot resolve. I have tried to use the ic_launcher which would not work so I added my own wuno_launcher and that will not work either.

private Notification getNotification(String content) {
        Notification.Builder builder = new Notification.Builder(this);
        builder.setContentTitle("New Affirmation");
        builder.setContentText(content);
        builder.setSmallIcon(R.drawable.wuno_launcher); // error here cannot resolve symbol
        return builder.build();
}

But I am sure I have the icon added as you can see in the picture below.

You should only place `ic_launcher`icons in the `mipmap` folder. Move any other drawables to a `drawable` folder (e.g. `drawable-xhdpi`) — Ed Holloway-George, May 17 '16 at 15:14

If you use mipmap folder image so you have use mipmap instead of drawable. Do something like this

builder.setSmallIcon(R.mipmap.wuno_launcher)

Thanks man. So that was why the ic_launcher would not work. So For my custom image I would drop in drawable. But the ic_luancher just use your answer. – wuno May 17 '16 at 15:33

According to the Google documentation, mipmap icons are used only for launcher icon which is also known as app_icon. Mipmap icons are reffered by using R.mipmap

Here is a good explanation of the same
