三星 S7 上的 TransactionTooLargeException

Question

我的一个应用在三星 S7 上引发以下异常：

java.lang.RuntimeException:

(NotificationManager.java:342)

at android.app.NotificationManager.notifyAsUser 
(NotificationManager.java:336)

这里是第 202 行的代码：

notificationManager.notify(NOTIFICATION_ID, mBuilder.build());

我也使用三星 S7，但从未遇到过该错误。我也无法使用 ansdroid studio 模拟器重现该错误。所以我不知道如何修复我无法重现的错误。 有什么想法吗？

可能的原因是您在 NotificationManager#notify 之前更新 RemoteViews 实例，而不是重新创建一个新实例，从而产生内存泄漏。我在another answer描述了这个案例
