Repeating Alarm in Android

由 折月煮酒 提交于 2019-12-24 14:56:11
问题 What is the best way to implement repeating alarm in my android application? Every user selects a specific time and I want to notify them when this time approaches on daily bases. I have come across this, but I am wondering whether this is the best way? 回答1: The alarm manager should meet your needs. There is no better way except for maybe having a server ping your client.

Android AlarmManager is not triggering alarm on next day when idle

由 大憨熊 提交于 2019-12-23 04:29:18
问题 I know there are dozens of similar threads on SO about this topic but I just couldn't find one that really solves the problem / or identifies the root cause. First of all, I'm targetting SDK 22 (Android 5.1) which means I could use the AlarmManager + WakefulBroadcastReceiver + IntentService even if this is not the latest way of doing things. I'm not interested in the JobScheduler etc solutions, I just want to understand what is happening and why. The phone I'm testing on has Android 8.0, but

How to detect alarm-based blocking RabbitMQ producer?

由 僤鯓⒐⒋嵵緔 提交于 2019-12-23 03:52:11
问题 I have a producer sending durable messages to a RabbitMQ exchange. If the RabbitMQ memory or disk exceeds the watermark threshold, RabbitMQ will block my producer. The documentation says that it stops reading from the socket, and also pauses heartbeats. What I would like is a way to know in my producer code that I have been blocked. Currently, even with a heartbeat enabled, everything just pauses forever. I'd like to receive some sort of exception so that I know I've been blocked and I can
