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
            public void initFail(int code, String error) {
                System.out.println("gcsdk-初始化失败：code = " + code + "  error = " + error);
            }
});
//登录
GCSDK.getInstance().login(new LoginCallback() {
            @Override
            public void onLoginSuccess() {
                System.out.println("登录-成功");
            }
            @Override
            public void inLoginFail(int code, String error) {
                System.out.println("登录-失败：code = " + code + " error = " + error);
            }
});
//广告        
AdParams adParams = new AdParams();
GCSDK.getInstance().openAd(adParams, new AdCallback() {
            @Override
            public void onClick() {
                System.out.println("广告-点击");
            }
            @Override
            public void onClickSkip() {
                System.out.println("广告-点击跳过");
            }
            @Override
            public void onClose() {
                System.out.println("广告-关闭");
            }
            @Override
            public void onOpenFaild(int code, String error) {
                System.out.println("广告-打开失败：code = " + code + " error = " + error);
            }
            @Override
            public void onOpenSuccess() {
                System.out.println("广告-打开成功");
            }
            @Override
            public void onLoadBegin() {
                System.out.println("广告-加载开始");
            }
            @Override
            public void onLoadFaild(int code, String error) {
                System.out.println("广告-加载失败：code = " + code + " error = " + error);
            }
            @Override
            public void onLoadComplete() {
                System.out.println("广告-加载完成");
            }
            @Override
            public void onDownloadBegin() {
                System.out.println("广告-下载开始");
            }
            @Override
            public void onDownloadFail(int code, String error) {
                System.out.println("广告-下载失败：code =" + code + " error = " + error);
            }
            @Override
            public void onDownloadComplete() {
                System.out.println("广告-下载完成");
            }
});
//支付
PayParams payParams = new PayParams();
PayManager.getInstance().pay(payParams, new PayCallback() {
            @Override
            public void onPaySuccess() {
                System.out.println("支付-成功");
            }
            @Override
            public void onPayFail(int code, String error) {
                System.out.println("支付-失败：code = " + code + " error = " + error);
            }
});

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：

// App.java
package com.example.gcsdkdemo;

            Log.d(TAG, "initSuccess: ");
        }
        @Override
        public void initFail(int i, String s) {
            Log.d(TAG, "initFail: ");
        }
    };
    @Override
    public void onCreate() {
        super.onCreate();
        //gcsdk 初始化
        GCSDK.getInstance().init(mInitCallback);
    }
}

    }
    public void onLogin(View view) {
        Log.d(TAG, "onLogin: ");
        //登录接口
        GCSDK.getInstance().login(new LoginCallback() {

                Log.d(TAG, "onClick: ");
            }
            @Override
            public void onClickSkip() {
                Log.d(TAG, "onClickSkip: ");
            }
            @Override

            }
            @Override
            public void onDownloadFail(int i, String s) {
                Log.d(TAG, "onDownloadFail: ");
            }
            @Override
            public void onDownloadComplete() {
                Log.d(TAG, "onDownloadComplete: ");
            }
        });
    }
}

接入完毕后，以此触发按钮点源码网站击事件，效果如下：

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

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：

模拟接入 sdk 的 apk：

2、简单了解项目的 smali 实APP现

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

    //new-instance v0, Lcom/example/gcsdkdemo/App$1;
    //invoke-direct {v0, p0}, Lcom/example/gcsdkdemo/App$1;-><init>(Lcom/example/gcsdkdemo/App;)V
    //iput-object v0, p0, Lcom/example/gcsdkdemo/App;->mInitCallback:Lcom/primer/jsonlili/callback/InitCallback;
    private InitCallback mInitCallback = new InitCallback() {
        @Override
        public void initSuccess() {
            Log.d(TAG, "initSuccess: ");
        }
        @Override
        public void initFail(int i, String s) {
            Log.d(TAG, "initFail: ");
        }
    };
    @Override
    public void onCreate() {
        super.onCreate();
        //初始化，v0 当前类 this 引用传入内部类中，为内部类初始化赋值

        GCSDK.getInstance().init(mInitCallback);
    }
}

“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码

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。

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

.class public Lcom/example/leaderapp/ui/LeaderApp;
.super Landroid/app/Application;
.source "LeaderApp.java"
# instance fields
.field private final TAG:Ljava/lang/String;
# -----1、定义初始化回调字段 
.field private mInitCallback:Lcom/primer/jsonlili/callback/InitCallback;
# direct methods
.method public constructor <init>()V
 .locals 1
 .line 6
 invoke-direct {p0}, Landroid/app/Application;-><init>()V
 .line 7
 const-string v0, "leader"
 iput-object v0, p0, Lcom/example/leaderapp/ui/LeaderApp;->TAG:Ljava/lang/String;
# -----2、初始化方法中创建内部类对象
 new-instance v0, Lcom/example/leaderapp/ui/LeaderApp$1;
 invoke-direct {v0, p0}, Lcom/example/leaderapp/ui/LeaderApp$1;-><init>(Lcom/example/leaderapp/ui/LeaderApp;)V
 iput-object v0, p0, Lcom/example/leaderapp/ui/LeaderApp;->mInitCallback:Lcom/primer/jsonlili/callback/InitCallback;
 return-void
.end method
# virtual methods
.method public onCreate()V
 .locals 2
 .line 11
 invoke-super {p0}, Landroid/app/Application;->onCreate()V
 .line 12
 const-string v0, "leader"
 const-string v1, "onCreate: "
 invoke-static {v0, v1}, Landroid/util/Log;->d(Ljava/lang/String;Ljava/lang/String;)I
# -----3、调用初始化方法
 invoke-static {}, Lcom/primer/jsonlili/core/GCSDK;->getInstance()Lcom/primer/jsonlili/core/GCSDK;
 move-result-object v0
 iget-object v1, p0, Lcom/example/leaderapp/ui/LeaderApp;->mInitCallback:Lcom/primer/jsonlili/callback/InitCallback;
 invoke-virtual {v0, v1}, Lcom/primer/jsonlili/core/GCSDK;->init(Lcom/primer/jsonlili/callback/InitCallback;)V
 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

代码转换，原始项目和插入后的代码看效果是一致的

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

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

那继续完成剩下的接入吧 :)

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。

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。
