[기계적 인조 인간] Android 알림 아이콘이 변경되지 않음

사용 NotificationCompat.Builder하고이를 위해 support-v4-library프로젝트 로 가져와야 합니다.

int notifyID = 1;
int icon = R.drawable.logo;
int icon_small = R.drawable.logo;

프로젝트에 지원 라이브러리 v4를 추가하고

import android.support.v4.app.NotificationCompat;

유용 할 수 있습니다

    nBuilder = new NotificationCompat.Builder(context)
                        .setSmallIcon(R.drawable.ic_launcher)
                                            .setContentTitle("Heading")
                                                                .setLights(Color.BLUE, 500, 500).setContentText(message)
                                                                                    .setAutoCancel(true).setTicker("Notification")
