我刚才添加的通知图标，通知栏在我的应用程序，它支持Android> = 11，它开始抛出以下错误：

I have just added notification icon to the notification bar in my app, which supports Android >= 11 and it started to throw below error:

java.lang.NoSuchMethodError: android.app.Notification$Builder.build

下面是我的code的一部分，负责建设的通知。

Below is my part of code responsible for building notification.

navigationIntent = new Intent(this, MainActivity.class);
navigationIntent.setAction(Intent.ACTION_MAIN);
navigationIntent.addCategory(Intent.CATEGORY_LAUNCHER);
navigationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP|Intent.FLAG_ACTIVITY_SINGLE_TOP);
pi = PendingIntent.getActivity(this, 0, navigationIntent,0);

notification = new Notification.Builder(this)
.setContentIntent(pi)
.setSmallIcon(R.drawable.splash_logo)
.setContentTitle("Status")
.setContentText("Standby mode")
.build();

有没有人有，为什么我得到的NoSuchMethodError简单.build方法的任何想法？还是我失去了一些东西在这里？

Does anyone have any idea why I'm getting NoSuchMethodError for simple .build method? Or am I just missing something here?

先谢谢了。

更新看来，我认为.build方法已在API16，愚蠢的问题增加了，但也许这将帮助别人：）

UPDATE It appeared to me that .build method has been added in API16, stupid question, but maybe it will help someone :)

推荐答案

答案是一样的，如下：java.lang.NoSuchMethodError: android.app.Notification $ Builder.addAction

The answer is just the same as here: java.lang.NoSuchMethodError: android.app.Notification$Builder.addAction

您可以使用 NotificationCompat.Builder 从Android支持包（ android.support.v4.app.NotificationCompat.Builder ）。

You can use NotificationCompat.Builder from the Android Support package (android.support.v4.app.NotificationCompat.Builder).
