autojsNativeJs: A JavaScript repository from snailuncle

js转dex, 可以参考此仓库 batchJs2Dex

webpack打包多个autojs的js文件为一个js文件, 可以参考此仓库 webpack-autojs

生成so教程

用as创建一个新项目, 名字是TestSo

com.jia.testso.MainActivity , 与 MainActivity同级别, 新建一个Main.java

package com.jia.testso;

import java.lang.reflect.Field;
import java.lang.reflect.Method;

public class Main{

    static{
        System.loadLibrary("jni");
    }

    public native static Object init(ClassLoader loader);

}

生成.class文件 buidl -> make project

F:\myGithub\TestSo\app\build\intermediates\javac\debug\classes\com\jia\testso\Main.class
在app/src/main文件夹下新建一个jni文件夹
打开Android Studio的终端，cd到这个目录app/src/main/jni
输入命令,用javah命令生成生成c\c++头文件, 这个jni文件夹下生成一个.h文件

javah -jni -classpath F:\myGithub\TestSo\app\build\intermediates\javac\debug\classes com.jia.testso.Main

请更改为自己的路径和包名

在jni目录下新建一个c/c++source file ,取名test.cpp 实现上面.h文件中的方法。

		jmethodID defmethod = env->GetStaticMethodID(cls2, "getDefault", "()Lcom/stardust/autojs/execution/ExecutionConfig;");
		jobject defobj = env->CallStaticObjectMethod(cls2, defmethod);
		
		jmethodID cbmethod = env->GetStaticMethodID(cls, "getInstance", "()Lcom/stardust/autojs/ScriptEngineService;");

		jmethodID exmethod = env->GetMethodID(cls, "execute", "(Lcom/stardust/autojs/script/ScriptSource;Lcom/stardust/autojs/execution/ExecutionConfig;)Lcom/stardust/autojs/execution/ScriptExecution;");
		jobject exobj = env->CallObjectMethod(cbobj, exmethod, ssobj, defobj);
		
		return exobj;
	}
}

在jni文件夹下新建Android.mk和Application.mk文件。

Android.mk

   LOCAL_PATH := $(call my-dir)
   include $(CLEAR_VARS)
   LOCAL_MODULE := jni
   LOCAL_SRC_FILES := test.cpp
   include $(BUILD_SHARED_LIBRARY)

Application.mk

   APP_PLATFORM := android-15
   APP_ALLOW_MISSING_DEPS=true

设定ndk路径 project structure / SDK Location / Android NDK location

C:\Users\jia\AppData\Local\Android\Sdk\ndk\21.0.6113669
终端进入到jni目录，输入指令 ndk-build,就会生成相应的so文件。
```
F:\myGithub\TestSo\app\src\libs\armeabi-v7a\libjni.so
```

解压apk, 提取classes2.dex

F:\myGithub\TestSo\app\build\outputs\apk\debug\app-debug.apk

把libjni.so 和classes2.dex 复制到/sdcard/脚本
用普通版autojs执行脚本
