如何在后台或睡眠模式采样加速度计数据 [英] How to sample accelerometer data in the background or on the sleep mode

问题描述

我有一个计划，将采样加速计数据所有的时间，做了一些分析。但我发现，当pressing电源按钮或在睡眠模式下，系统不会在一段时间后采样数据。是否有人知道如何让加速度运行在后台收集数据？

I have a program which will sample accelerometer data all the time and do some analysis. But I find that when pressing the power button or in the sleep mode, the system will not sample data after a period of time. Does anybody know how to let accelerometer run in the background to collect data?

非常感谢！

推荐答案

您需要设置一个PARTIAL_WAKE_LOCK将保持CPU运行，仍然允许在屏幕熄灭。当然，电池会更快耗尽。

You'll need to set a PARTIAL_WAKE_LOCK which will keep the CPU running and still allow the screen to go off. Of course, the battery will run down faster.
