java警报，通知无错误，但不显示

Question

我试图在Android Studio中使用通知发出警报，我尝试了this link，但出现了错误“强制关闭”。日志Cat中没有错误消息。请帮我找出这个问题。我的完整代码My Complete Code is here

public class MyAlarm extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        Log.d("Mine", "Set Daily");

        NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(context)
            .setSmallIcon(R.drawable.ic_notifications_white)
            .setContentTitle("My notification")
            .setContentText("Hello World!");

        NotificationManager notificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
        notificationManager.notify(001, mBuilder.build());
    }
}

Answer 1

我猜你没有把广播接收器包括在AndroidManifest中。xml

<receiver 
    android:name="MyAlarm" >
</receiver>
