Apk包分析

rabbit提供了一个apk-analyzer.jar文件，可以通过运行这个jar包来分析apk的内容，目前分析的点包括:

1. app基本信息
2. 大图
3. apk组成
4. 重复文件
5. apk方法数

可用的分析jar:apk-analyzer.jar

使用配置

apk-analyzer.jar在运行时需要一个配置文件:

java -jar apk-analyzer.jar apk-analyzer-config.json

上面apk-analyzer-config.json中约定的格式如下:

{
    "apkPath":"xxxx/app-Release.apk",
    "methodGroup":[{
        "name":"xxx",
        "package":"com.xxx.xx"
    }],
    "classMappingFilePath":"/Users/susionwang/Desktop/apk-analyzer/apk-analyzer-config.json",
    "maxImageSizeKB":30,
    "uploadPath":"xxx/upload"
}

• apkPath : 待分析的apk的路径
• methodGroup : apk方法数统计归组
• classMappingFilePath : mapping文件的路径
• maxImageSizeKB : 大于多少KB的图片会当做大图被检测出来。
• uploadPath : 分析结果上传的地址, 数据格式与基本上报格式一致:数据上报

分析结果示例

分析结果会输出在apk-analyzer-result.json文件中:
