这个方法就强大了，AXMLPrinter2是还原AndroidManifest.xml和main.xml的工具，直接打开这两个xml文件是乱码，而通过还原之后，可以很明白的看到里面的内容（我猜测还是使用了字节异或的方式加的密）。
baksmali.jar是反解析dex的工具，smali.jar则是再还原成dex的工具
操作方式如下：
1、java -jar AXMLPrinter2.jar D:\play\AndroidManifest.xml > AndroidManifest.txt
2、java -jar AXMLPrinter2.jar D:\play\res\layout\main.xml > main.txt
3、java -jar baksmali-1.2.5.jar -o classout/ d:\play\classes.dex
baksmali可解析（注意，是解析，不是反编译）原java包以及引用的lib包，解析出的文件认真看还是能看懂，比如以下片段：

invoke-virtual {p0, v0}, Lcom/paul/test/a;->setPressed(Z)V
invoke-super {p0, p1, p2}, Landroid/view/View;->onKeyUp(ILandroid/view/KeyEvent;)Z
move-result v0
return v0
.end method
认真一看，就知道：
# static fields 定义静态变量的标记
# instance fields 定义实例变量的标记
# direct methods 定义静态方法的标记
# virtual methods 定义非静态方法的标记
以onKeyUp方法为例，其中定义了处理逻辑，if-eq p1, v0, :cond_8 表示如果p1和v0相等，则执行cond_8的流程：
:cond_8
invoke-direct {p0}, Lcom/paul/test/a;->d()V
调用com.paul.test.a的d()方法
不相等： if-ne p1, v0, :cond_b 则执行cond_b的流程：
:cond_b
const/4 v0, 0x0
invoke-virtual {p0, v0}, Lcom/paul/test/a;->setPressed(Z)V
invoke-super {p0, p1, p2}, Landroid/view/View;->onKeyUp(ILandroid/view/KeyEvent;)Z
move-result v0
大概意思就是调用com.paul.test.a的setPressed方法，然后再调用父类View的onKeyUp方法
最后 return v0
该方法，能把外部引用的lib包类也解析出来，能开到包的全貌。缺点在于，解析出的smali文件并不是反编译出的java文件，可读性降低了，但仔细研究也能看出大概。
