我已经在我的项目库中添加了android-support-v4.jar ......但是我收到了这个错误：

Could not find class 'android.app.Notification$Builder', referenced from method org.secure.sms.SmsReceiver.showNotification

确保文件夹android-support-v4.jar内有/libs 并将其添加到您的班级：

import android.support.v4.app.NotificationCompat;

找不到类'android.app.Notification $ Builder
