如何测量我的应用程序在Android上的功耗？

Question

我已经开发了一个Android应用程序，我想知道我的应用程序在Android设备上的耗电量。我在堆栈溢出上遇到了许多线程，但没有一个线程帮了我。

在Android中有没有任何应用程序可以测量我的应用程序的耗电量，或者其他可行的方法？

从this Stack Overflow post的答案

我使用了“电池历史学家”，并生成了batteryinfo.txt和batteryinfo.html

Batteryinfo.txt如下所示

当我打开Batteryinfo.html时，它会显示“无法找到结束时”。

我按照下面的文章中的答案并注释掉了前面提到的代码。

Battery historian cannot find end time android

这一次，当我运行命令从batteryinfo.html生成batteryinfo.html时，它会显示一个错误(这将引用注释掉的3行代码)。

注意:由于我的设备不支持使用电池统计，所以我使用电池信息。

我想打开包含细节的batteryinfo.html。

Answer 1

我不知道你说的是什么意思，看不懂背景中的估计值。

看看我在Android App power consumption上的答案

“首先，Google Play的电源导师已经过时了。我检查了它的源代码，发现功率估计模型是针对一些旧的移动模式的，电源导师的值比实际的耗电量小得多。

因此，我建议使用电池历史学家，这是由谷歌开发，用于估计每个应用程序的电池消耗。但它是用Python/Go编写的。它将在html文件中显示硬件调用。您可以在相应的文本文件中找到每个应用程序的电池消耗量。

https://developer.android.com/studio/profile/battery-historian.html“

它将创建一个batterystats.txt，在设置中显示与它完全相同的内容。
