android - 无法更改 Google Play 服务 Activity 识别的请求间隔

Question

如标题所述，我的问题是无法正确控制 Activity 识别请求。我的代码是这样的:

arclient.requestActivityUpdates(ACTIVITY_DETECT_INTERVAL, pIntent);

ACTIVITY_DETECT_INTERVAL =2*60*1000(2 分钟)

但是日志显示

01-27 12:21:49.412: I/ActivityRecognitionService(5458): Still   92
01-27 12:21:54.462: I/ActivityRecognitionService(5458): Still   92
01-27 12:21:59.492: I/ActivityRecognitionService(5458): Still   69
01-27 12:22:04.562: I/ActivityRecognitionService(5458): Still   76
01-27 12:22:09.662: I/ActivityRecognitionService(5458): Still   76
01-27 12:22:14.592: I/ActivityRecognitionService(5458): Still   92
01-27 12:22:19.612: I/ActivityRecognitionService(5458): Still   77
01-27 12:22:24.622: I/ActivityRecognitionService(5458): Still   92
01-27 12:22:29.672: I/ActivityRecognitionService(5458): Still   92
01-27 12:22:34.892: I/ActivityRecognitionService(5458): Still   85
01-27 12:22:39.812: I/ActivityRecognitionService(5458): Still   92

原来间隔总是 5 秒。谁能帮帮我，先谢谢了。

根据 requestActivityUpdates documentation :

Activities may be received more frequently than the detectionIntervalMillis parameter if another application has also requested activity updates at a faster rate. It may also receive updates faster when the activity detection service receives a signal that the current activity may change, such as if the device has been still for a long period of time and is then unplugged from a phone charger.

您当然可以在您自己的应用程序中过滤掉事件(假设您存储上次收到事件的时间，然后忽略从那时到该时间之后 2 分钟之间的事件)，但是无法限制传入 Activity 的数量更新超出您手机上最耗电的应用程序请求或您的请求，无论哪个更大。
