apk反编译(2)smali语言及文件

Smali语言是Davlik的虚拟机使用的一种语言，用toolapk反编译apk后，可以见到大量的.smali文件。

可以按照smali语法对其修改，然后重新生成一个未签名的apk。

下面是一个示例：

 .class final Lcom/tencent/smtt/sdk/QbSdk$;
 .super Ljava/lang/Object;
 .source "SourceFile"

 # interfaces
 .implements Lcom/tencent/smtt/sdk/QbSdk$b;

 # annotations
 .annotation system Ldalvik/annotation/EnclosingClass;
     value = Lcom/tencent/smtt/sdk/QbSdk;
 .end annotation

 .annotation system Ldalvik/annotation/InnerClass;
     accessFlags = 0x8
     name = null
 .end annotation

 # direct methods
 .method constructor <init>()V
     .locals

     invoke-static {}, Lcom/tencent/mm/A;->a()V

     :cond_0
     return-void
 .end method
