####(1)usage: python dexParser.py Test.dex ####(2)例子：
Test.java源码
public class Test{
public int a;
private long b;
public static int c;
public int add(int a, int b){
return a + b;
}
public float minus(float a, float b){
return a - b;
}
public void print(){
System.out.println("Hello World!");
}
}用下面的dx命令生成dex文件 dx --dex --output=Test.dex Test.class
####(3)测试: python dexParser.py Test.dex 输出结构如下：
