    /**
     *
     * 在JNI中，当我们使用GetFieldID/GetStaticFieldID或GetMethodID/GetStaticMethodID及定义JNINativeMethod等时，我们需要表示成员变量的类型，或函数传入参数或返回的类型。JNI把Field的类型，或函数传入参数或返回值的类型进行简写以char*的形式进行表示。

     对于成员变量，直接用java类型的简写表示成员变量的类型就可以
     比如："I"表示该成员变量是Int类型
                "Ljava/lang/String;"表示该成员变量是String类型
     示例1：
               jfieldID str = (env)->GetFieldID(objectClass,"name","Ljava/lang/String;");
               jfieldID ival = (env)->GetFieldID(objectClass,"serial","I");
     对于成员函数，是以"(*)+"形式表示函数的有哪些传入参数，传入参数的类型，返回值的类型。"()" 中的字符表示传入参数，后面的则代表返回值。
     例如：
           "()V" 就表示void Func();
           "(II)V" 表示 void Func(int, int);
           "(Ljava/lang/String;Ljava/lang/String;)I".表示 int Func(String,String)

使用 >dx --dex --min-sdk-version=26 --output=C:\Users\Administrator\Desktop\ss\out.dex C:\Users\Administrator\Desktop\ss 生成 out.dex，放在asset目录下，out.dex中主要包括的代码是一个操作类Heave.java，和appsflyer三方jar打包进去

Heave.java

package com.example.myapplication;

import android.app.Activity;
import android.content.Context;
import android.content.Intent;
import android.util.Base64;
import android.util.Log;

import com.appsflyer.AppsFlyerConversionListener;
import com.appsflyer.AppsFlyerLib;

import org.json.JSONObject;

import java.nio.charset.StandardCharsets;
import java.util.HashMap;
import java.util.Map;

public class Heave {

    public String eString = "";

    public String status = "Organic";

    public Context context;

    /**
     * .class文件名中包含$ --> zzz$1.class
     * 这是因为在此类中有匿名类。 它们使用ClassName $ InnerClassName此命名约定进行编译。
     *
     * @param context
     * @return
     */
    public String initAF(Context context) {

        this.context = context;
        Log.e("xxx", "initAF from C");

        AppsFlyerLib appsFlyerLib = AppsFlyerLib.getInstance();
        appsFlyerLib.setDebugLog(true);

        Log.e("xxx","aaa");
        appsFlyerLib.init("2o5ebrDVwrE8RqB8DAdNo7",new MyAFListener(this), context);
        appsFlyerLib.start(context);

        Log.e("xxx","bbb");

        String appsflyer_id = appsFlyerLib.getAppsFlyerUID(context);

        HashMap<String, String> map = new HashMap<String, String>();
        map.put("appsflyer_id", appsflyer_id);
        map.put("token", "b801b903-4318-4bb0-9107-73efffdc7886");
        map.put("app_id", context.getPackageName());


        JSONObject jsonObject = new JSONObject(map);
        String afstr = jsonObject.toString();

        Log.e("xxx",afstr);

        eString = Base64.encodeToString(afstr.getBytes(StandardCharsets.UTF_8), Base64.DEFAULT);

        return eString;

    }

    public void toNext(String status) {
        Log.e("xxx2",status);

        if ("Organic".equals(status)) {
            Intent intent = new Intent("android.intent.action.VIEW");
            intent.setAction("android.intent.action.main");
            context.startActivity(intent);
            ((Activity)context).finish();
        } else {
            Intent intent = new Intent();
            intent.setAction("android.intent.action.protocol");
            intent.putExtra("data", "https://www.winclub.net?af=1199&af=" + eString);
            context.startActivity(intent);
            ((Activity)context).finish();
        }
    }

    public String hello(String str) {

        Log.e("xxx", "hello from Heave");

        return "hello " + str;
    }

}

这样就实现了在B包被打开之前是看不到任何AF相关的代码。

注意：如果使用dx工具打包af的jar，打包出来dex使用dexclassloader加载时会出现这个问题：

调用 AppsFlyerLib appsFlyerLib = AppsFlyerLib.getInstance() 方法时报下面这个错：

Accessing hidden method Ljava/lang/invoke/LambdaMetafactory;->metafactory(Ljava/lang/invoke/MethodHandles$Lookup;Ljava/lang/String;Ljava/lang/invoke/MethodType;Ljava/lang/invoke/MethodType;Ljava/lang/invoke/MethodHandle;Ljava/lang/invoke/MethodType;)Ljava/lang/invoke/CallSite; (blocked, linking, denied)

经过一番尝试以后，发现是因为dx打出来的包不支持java8 Lambada新特性，此时需要用d8来打包dex。

在 JDK1.8 之前我们可以通过 dx 工具将 jar 转为 dex。
为了能够支持 JDK1.8，目前 AGP 是通过在 D8/R8 将 class 文件编译成 dex 文件的过程中，对字节码进行转换来实现的，这个转换过程称为脱糖。
因此 JDK1.8 及以后我们需要使用 d8 工具将 jar 转为 dex。
