3. Configuring Goroot and Gopath

A. The role of Goroot is to tell the GO command and other related tools where to find the go package installed on your system, so here is the Go installation directory

B.gopath can be simply understood as a catalog of works, so create a Go project path

C. Finally configure the environment variables, put the Go bin directory in the PATH environment variable

   * * Download to the Gopath configuration directory

4. Enter below the $gopath/src/github.com/google/battery-historian directory

5. Run Battery Historian
   

   Enter $ go Run setup.go

   # Compile Javascript files using the Closure compiler

   Wait a few minutes, if the download is still not successful, you can manually download the following actions

   * * Download "closure-library" and "Closure-compiler" and "Flot-axislabels", unzip and put into Goroot directory Third_ The Closure-compiler and closure-library and Flot-axislabels folders below the Party folder: /battery-historian\third_party, if not all manually created

   B. Go run Cmd/battery-historian/battery-historian.go

   # Run Historian on your machine (make sure $PATH contains $GOBIN)

   $ go Run Cmd/battery-historian/battery-historian.go [--port <default:9999>]

7. Check if/battery-historian is running, login URL http://localhost:9999 view

   
   

   
   

Generate Bugreport

First, data preparation

1.windows cmd execute the following command to turn on battery data acquisition

adb shell Dumpsys batterystats--enable full-wake-history

2.windows cmd perform the following command to reset the battery data

adb shell Dumpsys batterystats--reset

Second, operation application, generate Bugreport

Unplug the USB, and then the test app to do the relevant operation, after a period of time, plug in the USB, run two commands.

1.windows CMD executes the following command to save the Bugreport information to the appropriate path, waiting for execution to complete

ADB bugreport > Bugreport.txt

2.windows cmd execute the following command to convert the above TXT document into an HTML file

Python historian.py-a bugreport.txt >battery.html

Note: Now do not know why the prompt error, can not find historian.py this file

The above historian.py is a script written in Python, so you need a Python environment that can be downloaded from GitHub, and when the above commands are executed, you will find two files, Bugreport.txt and battery.html, this time with Google Browser input http://localhost:9999, Upload bugreport.txt or you can open battery.html directly, the view is as follows:

The above is V2.0 version, you can switch to version 1, now to analyze the meaning of the various parameters:

V2.0 the indicator more, because there is no corresponding reference document, ask the relevant big God later. So we can only analyze the V1.0 first, may refer to http://blog.csdn.net/itfootball/article/details/44084159

Finally, we can also see the amount of power (estimated) that the process is consuming:
