安卓上找不到路径这个问题暂时用sd卡的根目录好啦。这里已经修复并测试通过
但这个测试工程是安装在有sd卡的手机的sd卡上的
或者如阳光七月所说
将Lua的源代码用Quick提供的工具打包，用加载包的方式进行代码的加载工作，就不会出现问题了。
如果不愿意打包，也可以自己修改executeScriptFile接口，先自己载入文件数据，用luaL_dostring接口来调用。这样也行
－－－－－－－－－－－－dataSave.lua－－－－－－－－－－－－－－
local function readInFiles(filePath, str, sType)
local result = {}
– 把字符串写入文件
local function writeFile(fileName, strVal)
if device.platform == “android” then
local tab = string.split(fileName, “/”)
local tmpPath = “/mnt/sdcard/”
fileName = tmpPath … tab#tab]
end
local pFile,err = assert(io.open(fileName, sType))
if err then
return false
else
pFile:write(strVal)
pFile:close()
return true
end
end
return writeFile(filePath, str)
end
–打印输出信息
function showLog( … )
local traceback = string.split(debug.traceback("", 2), “\n”)
local str = string.split(string.trim(traceback), “/”)
print(str#str] … “\n”, …)
end
– 格式化table表

– 获取文件路径
local function getDataTablePath(fileName)
fileName = tostring(fileName)
local path = CCFileUtils:sharedFileUtils():getWritablePath()
if device.platform == “android” then
path = “/mnt/sdcard/”
end
local filePath = path … fileName … “.lua”
return filePath
end
– 判断文件是否存在
local function isDataTableExist(fileName)
local filePath = getDataTablePath(fileName)
return CCFileUtils:sharedFileUtils():isFileExist(filePath)
end
–
以下是需要暴露出去的接口
–]]
– 保存数据
function saveDataTableToFile(tab, fileName)
local fStr =
local table = %s
return table
]]
sType = sType or ‘w’
local filePath = getDataTablePath(fileName)
tab = forMatTable(tab)
–tab = varForMat(tab)
local str = string.format(fStr, tab)
if readInFiles(filePath, str, sType) then
–showLog(“数据保存到 “,filePath,” 操作成功”)
end
end
– 读取数据
function getDataTableFromFile(fileName)
local filePath = getDataTablePath(fileName)
if isDataTableExist(fileName) then
if device.platform == “android” then
local tmpPath = “/mnt/sdcard/”
fileName = tmpPath … fileName … “.lua”
end
local info = require(fileName)
return info
else
showLog(“读取失败,未找到: “,filePath,” 该文件”)
return {}
end
end
– 删除数据
function deleteDataTable(fileName)
local filePath = getDataTablePath(fileName)
if isDataTableExist(fileName) then
os.remove(filePath)
else
showLog(“删除失败,未找到: “,filePath,” 该文件”)
end
end
– 测试
– local t = {{x=2, b=“right”}, {2, 6,8}, {name = “哈哈”, sex = “女”}}
– 保存数据
– saveDataTableToFile(t, “tip”)
– 读取数据
– local a = getDataFromFile(“tip”)
– print(a.b)
