adb is the Android CLI tool with which you can interact with your android device, from your PC
You must enable developer mode (tap 7 times on the build version in parameters) and install adb on your PC.
Don't hesitate to read comments, there is useful tips, thanks guys for this !

转换方法:
使用附件中的java程序。命令如下：
cp Vector2Svg.java path/to/xml_dir
javac Vector2Svg.java
java Vector2Svg ./*.xml
mkdir svg_dir
I have collected and moderated these ideas from various public sources and put into one place so that problem solvers and solution developers may find inspirations. Because I wish to update it regularly, I have setup as a single page wiki. You may try these ideas on hackathons/competitions/research; some are quite intense problems and some are not. Many of the problems were prepared keeping Dhaka/Bangladesh in mind, but of course can be applied to just about any underdeveloped/developing and sometimes developed countries.

| Calculates the estimated brightness of an Android Bitmap. | |

| When pixelSpacing = 1, the method actually calculates the real average brightness, not an estimate. | |
| This is what the calculateBrightness() shorthand is for. | |
| Do not use values for pixelSpacing that are smaller than 1. | |
