API级别低于26的通知代码
[英]Notification code for API levels lower than 26
问题描述
I am trying to target my Android application from API level 23 to the latest API level. 
我正在尝试将我的Android应用程序从API级别23定位到最新的API级别。 However starting in Android 8.0 (API level 26), all notifications must be assigned to a channel which wasn't the case previously. 但是，从Android 8.0（API级别26）开始，必须将所有通知分配给以前不是这种情况的通道。 Right now I am checking the condition if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) to make the notification with the NotificationChannel if API level is greater than 26, so my question is that will the import statement for the NotificationChannel import android.app.NotificationChannel; 现在我正在检查条件if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O)如果API级别大于26，则使用NotificationChannel进行通知，所以我的问题是NotificationChannel import android.app.NotificationChannel;的import语句import android.app.NotificationChannel; cause an issue in the API versions lower than 26. Should I maintain different activities for the different APIs? 导致API版本低于26的问题。我应该为不同的API维护不同的活动吗？

will the import statement for the NotificationChannel import android.app.NotificationChannel;
No. 没有。
Trying to use NotificationChannel on older devices would be a problem, but that is what the if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) is for. 尝试在旧设备上使用 NotificationChannel会出现问题，但这就是if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O)的用途。 Simply having the import will not be an issue. 简单地进行导入不会成为问题。
