从 smali 接入第三方 sdk

遇到过这种场景吗?

什么样的场景需要从 smali 语言层面接入第三方 sdk 呢?

一般都是 java 语言接口,一目了然,搞个 smali 不是没事找事?

其实不然

场景不同,我还真就遇到这种常规操作了 ———— 从 smali 接入 sdk

有一天

Leader 给你发一个 apk 文件

Leader:需要把我们的 sdk 接入到这个 apk 里面源码编辑器下载,但是没有 apk 的 Android 工程,能实现吗?

Programmer:应该可以,给我点时间研究下

Leade接口类型r:好,两天可以吧?我排期一下

Programmer:行

就这么简单:一个 apk,把我们的 sdk 接入到里面

不如写个 Demo 看看?

1、准备一个 sdk: gcsdk-1.0.0.jar

2、准备一个 apk: app-0.apk【这个是需要你接入 sdk 的 apk】

3、创建一个空白 Android 项目,预备接入 sdk: 生成的 apk 备用 app-1.apk

我们简单实现一个 sdk,实际上接入的第三方 sdk 可能会更复杂一点

  • gcsdk-1appearance.0.0 接入示例
// 初始化
GCSDK.getInstance().init(new InitCallback() {
            @Override
            public void initSuccess() {
                System.out.println("gcsdk-初始化成功");
            }
            @Override

                System.out.println("gcsdk-初始化失败:code = " + code + "  error = " + error);
            }
});
//登录

  • 创建一个空白的 Android 项目,开始接入 gcsdk接口卡,接入完成后appointment打包生成 apkAPP 留着备用,用于获取接入 sdk 的 smali 代码

以下是接入示例:

接入完毕后,以此触发按钮点源码网站击事件,效果如下:

从 smali 接入第三方 sdk

  • Leader 的 apk:

也模拟创建一个 apk,比较简单,每一个 fragment 有一个按钮,我们的目的也很明确 为每个按钮的点击事件实现对应 sd初始化失败是怎么解决k 的接口调用

从 smali 接入第三方 sdk


了解下项目中的 smali?

1、获得 smaliandroidstudio安装教程

java -jar apktool_2.6.0.jar [-r] d app-0.apk
java -jar apktool_2.6.0.jar [-r] d app-1.apk

Leader 的 apk:

从 smali 接入第三方 sdk

模拟接入 sdk 的 apk:

从 smali 接入第三方 sdk

2、简单了解项目的 smali 实APP

本次使用 VSCode 查看 smali 代码,同时安装插件 smali、smali2java

模拟接入 sdk 的 apk

  • App.java & App.smali

以下 smali 主要是列举与 sdk 相关,主要关注的是——sdk 接入相关代码生成的 s源码1688mali 具体有哪些、是如何结接口类型合使用的

“日久生情”,代码看多了自然掌握的 smali 知识的就更多吧

Leader 的 apk

假如我们已知代码插入点(调用点源码编程器)位置————对应按钮的点击事件;那么我们更应该的点是——找到对应按钮的点击事件所在位置、如何正确插入 smali 代初始化电脑的后果

从 smali 接入第三方 sdk

要不 smali 接入看看?

1、先把 sdk 相关的所有 smali 源码复制到预备接入 apk 反编译的工程目录适当位置处

这里我新建 smali_classes9 目录,gcsdk 比初始化是什么意思较简单,只接口测试用例设计有纯代码,没有资源、soappstore 文件等;如果有,也需要复制到工程的相应目录下,确保项目能够编译成功、运行期间能加载到代码,这是项目能够运行的前提。

从 smali 接入第三方 sdk

下面就开始往预备接入的 apk 代码中合适位置插入 sdk smali 代码。

2、LeaderApp.java & LeaderApp.smali

.super Landroid/app/Application;
.source "LeaderApp.java"
# instance fields
.field private final TAG:Ljava/lang/String;

 return-void
.end method
# virtual methods

# -----3、调用初始化方法

 return-void
.end method
# -----4、创建 LeaderApp$1.smali,并更新路径、类等

插入完毕之后我们可以使用 VSCODE smali 插件代码转换查看是否插入初始化磁盘正确,可以做对比

从 smali 接入第三方 sdk

代码转换,原始项目和插入后的代码看效果是一致的

从 smali 接入第三方 sdk

手动签名、安装运行看日志,能看到 sdk 初始化正确,再次说明上述接入是无误的。

jarsigner -verbAPPose -keystore aa.keystore sign-app0.apk app-android平板电脑价格0.apk key0

从 smali 接入第三方 sdk

Tips:

  • 之前使用初始化电脑时出现问题 java -jar apktool.jar d ***.apk 反编译源码编辑器安装包,但在回编译时候可能回出现下面的错误,导致打包失败,日志中提到 res/目录,看日志像是资源问题。

W: invalid resource directory nam接口crc错误计数e: >/Users/jso源码nli/Desktop接口是什么/demo/0603/app-0/app-0/res navigati接口和抽象类的区别on brut.androlib.AndrolibExcep接口测试用例设计tion: brut.common.Br接口和抽象类的区别utException: could not exec (exit code = 1):

/Users/jsonli/Desktop/demo/0603/app-0/app-0/res, -M,

/Users/jsonli/Desktop/demo/0603/app-0/app-0/AndroidManifest.xml]

那么反编译时候不处理资源试试,apktool 加上 -r 参数java -jar apktool.jar -r d ***.apk,接着打包正常。

  • apktool 使用说明

4、Notific接口crc错误计数ationsFragment.smali、D源码时代ashboardAndroidFragmeappreciatent.smali

因为代码简单,且逻辑一致,剩下的支付和接口类型广告接口代码就不贴出来了,跟上述接入十分相似,没application有比较特别的地方。

检验结果与思考

结果:

  • smali 代码android/harmonyos插入完毕、保存
  • 使用 apktool 重新打包
  • 使用签名工具重新签名

依此点击按钮,触发点击事件,运行结果如我所愿,一切正常。

从 smali 接入第三方 sdk


思考:

A:为什么搞 smali 接入这么复杂,这不是给自己找坑吗?源码编程器

B:有时候真的存在这种场景,也是无措之举…

A:既然你已有 apk,可以把它转换为 java 代码,在 java 代接口测试用例设计码上接入不更清晰、省事,免除遇到很接口是什么多未知的坑,咋不这么干?

Bapprove:好像初始化是什么意思…也 可 以?

A:我觉得可以,借助 Androidandroid平板电脑价格Fk 工初始化游戏启动器失败具可以直接从 apk 中反编译出 java 代码,当然————如果是加固、加密的 apk 可能就没那么容易了!!!

B:我觉得也是,在 java 代码上接入方便多了。

B:我是有点想不明白,我遇到的一家 CP 就是直接在 smali 上面接入的!难道说是技术过硬,哪里接入都一样?或者有什么特接口和抽象类的区别殊的场景初始化失败是怎么解决???

A:想不明白就不想了,有时间你可以试试我说的转 java 之后接入

B:好的,村长


A:如果接入的第三方 sdk 是一个 aAPPar,包含一些资源文件,接入会不初始化英文会遇到其他问题?

B:这不是没可能,实操过方知晓

A:那下次准备下

B:… …

smali 可能没有想象中的那么简单,

也可能就是这么简单,

之间的差距可能就是对 smali 的认识和理解深浅之别。
