问题描述
Android中推送通知中可以显示的最大字符数是多少而没有文本被截断?
What is the maximum number of characters that can be displayed in push notification in Android without the text being truncated?
iPhone的文档说明通知有效负载已包含总共不到256个字节,但我无法找到类似Android的东西。
The documentation for iPhone states that the notification payload has to be under 256 bytes in total, but I was unable to find something similar for Android.
