CLE的使用笔记

CLE官网http://www.srplab.com/cn/index.html

下载CLE for Android，解压文件，拷贝 starcore_android_rX.X.jar到工程的libs目录，拷贝 libstar_java.so、libstarcore.so、libpython3.6m.so和libstar_python36.so到libs/x86目录，拷贝编写的Python源码和python需要的环境及标准库到src/main/assets目录.需要的python的.so文件可下载

android.python.x.x.x,解压获得。在build.gradle中android {}中添加

sourceSets.main.jniLibs.srcDirs = ['libs']

使用JAVA初始化CLE http://www.srplab.com/cn/files/cle_initialization.html

 import com.srplab.www.starcore.*;
 public class test_server{  

     StarCoreFactoryPath.StarCoreCoreLibraryPath = this.getApplicationInfo().nativeLibraryDir;
     StarCoreFactoryPath.StarCoreShareLibraryPath = this.getApplicationInfo().nativeLibraryDir;
     StarCoreFactoryPath.StarCoreOperationPath = "/data/data/"+getPackageName()+"/files";
     public static void main(String[] args){
     StarCoreFactory starcore=StarCoreFactory.GetFactory();
     StarServiceClass Service=starcore._InitSimple("test","123",0,0);
     StarSrvGroupClass SrvGroup = (StarSrvGroupClass)Service._Get("_ServiceGroup");  

     ......
     SrvGroup._ClearService();
     starcore._ModuleExit();
     }
 }  

java调用 python  http://www.srplab.com/cn/files/cle_javacallothers.html

1. 调用函数"_InitRaw"初始化python接口
2. 调用函数"_LoadRawModule"加载python脚本文件
3. 使用函数"_ImportRawContext("python","",false,nil);"获取python全局原生对象,python类
4. 使用函数"XX._Call("_StarCall",Args...)"或者"XX._New("","",Args,..)"创建python类的实例
5. 使用函数"XX._Call("funcname",...)"或者"XX._Get/_Set("Variable")"调用python函数,设置/获取python变量数值

python调用java http://www.srplab.com/cn/files/cle_pythoncallothers.html

1. 调用函数 "_InitRaw" 初始化java接口
2. 调用函数 "_LoadRawModule" 加载java脚本文件
3. 使用函数 "_ImportRawContext("java","",False,"");" 获取java类
4. 使用函数 "XX(Args...)" 创建java类的实例
5. 使用函数 "XX.func(...)"或者"XX.Variable"调用java函数，获取/设置java变量数值

         /*----run python code----*/
         SrvGroup._InitRaw("python36", Service); //调用函数_InitRaw初始化python接口
         StarObjectClass python = Service._ImportRawContext("python", "", false, "");
         // 设置Python模块加载路径
         python._Call("import", "sys");
         StarObjectClass pythonSys = python._GetObject("sys");
         StarObjectClass pythonPath = (StarObjectClass) pythonSys._Get("path");
         pythonPath._Call("insert", 0, appFile.getPath() + File.separator + "python3.6.zip");
         pythonPath._Call("insert", 0, appLib);
         pythonPath._Call("insert", 0, appFile.getPath());

         //调用Python代码
         Service._DoFile("python", appFile.getPath() + "/py_code.py", "");
         long time = python._Calllong("get_time");
         Log.d("", "form python time=" + time);
         tv1.setText("time:"+String.valueOf(time)  + "");
         //调用Python代码
         Service._DoFile("python", appFile.getPath() + "/test.py", "");
         int result = python._Callint("add", 5, 2);
         Log.d("", "result=" + result);
         tv2.setText("add:"+result  + "");
         //将一个java类设置给Python，变成Python类
         python._Set("JavaClass", Log.class);
         Service._DoFile("python", appFile.getPath() + "/calljava.py", "");

出现问题：ModuleNotFoundError("No module named 'encodings'",)Py_Initialize: unable to load the file system codec
A/libc: Fatal signal 6 (SIGABRT), code -6 (SI_TKILL) in tid 4184

解决方法：似乎是python版本的问题。

可以查看File appFile = new File("/data/data/"+getPackageName()+"/files");中appFile的值，是否包含多个版本的.so文件

参考：Android 平台的Python——CLE方案实现（三）

android 调用 python
