推荐答案
该项目是不完整的任何想象的延伸，但我创建了一个应用程序框架（有点...这是目标，它现在还没有）采取同样的措施。请查看 HTTP：//syspower.google$c$c.com 。你不能，除非你计算出使用的所有应用程序获得通过应用程序的比例，但你可以得到功耗的定量值。可以很明显的，然后用这些数字来计算的百分比。此外，你应该注意的是，功耗API是私有的，为了获得它，我不得不使用一些反射调用访问私有和隐藏的数据成员。鉴于这种情况，它可能会或可能不会与所有的Android版本（我已经与1.6-2.1测试过）的工作。我基本上扭转工程师从开源库中的FuelGuage应用程序。
The project isn't complete by any stretch of the imagination, but I created an application framework (kinda...that was the goal, it's not there yet) to do just this. Check out http://syspower.googlecode.com. You won't be able to get the percentage by application unless you calculate the usage for all applications but you can get quantitative values for power consumption. You can obviously then use those numbers to calculate a percentage. Also, you should note that the power consumption API is private and in order to access it, I had to use a number of reflective calls to access private and hidden data members. Given that, it may or may not work with all Android versions (I've tested it with 1.6-2.1). I basically had to reverse engineer the FuelGuage app from the open source repository.
