I have an app which has a service and a main activity. The service runs a count down timer and send an even to the activity which receives the event to paint/refresh the count down timer in the screen. Very simple. Now I am investigating battery usage, which is very very high
我将把长官从200米减少到800米,可操作的电线从500至800。 这必须拯救第一嫌疑犯。
但有几个问题:
我的主要问题是: 当屏蔽时(我有部分的警钟),roid是否继续更新屏幕? 如果是这样的话,我会试图在屏蔽时不提供复习信息(我能否发现屏幕是锁定的)。 你们是否认为这可以帮助?
你们是否知道在为挽救电池而进行方案规划或设计方面的最佳做法? 我一直在寻找一个网络,但没有发现任何有趣之处。
是否有数据库打开废物电池?
感谢
1. 您可使用Alarmmanager来规避最新情况。 (见http://developer.android.com/guide/topics/appwidgets/index.html) rel=“nofollow”>android appwidgets 。
注:如果该装置在更新时间(根据更新后的PeriodMillis的定义)时被装满,那么该装置就会起伏,以便进行更新。 如果你不每小时更新一次以上,这很可能给电池生活带来严重问题。 然而,如果你需要更经常地更新,并且(或)在装置被装满时不需要更新,那么,你就可以根据警示进行更新,而警示不会催复装置。 为此,请一名学者使用AlarmManager接收你的农民。 向ELAPSED-REALTIME或RTC提供警报,只有在装置觉醒时才会发出警报。 然后将PeriodMillis更新为零(“0”)。
这对植被和“热”特性来说,是有用的。
2. 我不知道一份正式文件。 但是,你应当提出以下问题: 是否需要定期更新? 如果活动时间已满5小时,你是否需要每隔二分钟或仅每分钟更新全球调查? 你们可以把最新情况推到后面:活动越近,更新越频繁。
3. 我认为不是。
(根据您的法典排列) 你们的服务会继续经营和发送耗用CPU周期和耗尽权力的最新活动。 无论你试图更新哪些活动,都已经在屏幕锁后暂停。 播放标准节目,供在屏幕上播放,仅供您服务并停止工作。 或者,如果收到有关Pause(Pause)回击的最新活动,则停止你的工作,并在Resume(a)上重新启用(如果没有任何重点的话,则无需再更新活动)。
见1和 gr和roid。 基本思想:没有用处。
它没有。 除非有人问。
