Tizen 网络应用程序适用于模拟器，但不适用于齿轮 3

我正在尝试开发一个从加速度传感器读取数据并将其保存在文本文件中的应用程序。使用Web应用程序开发，我设法使应用程序在模拟器上运行，但是当我在Samsung Gear 3 frontier上尝试时，它不起作用。有人能弄清楚我做错了什么吗？下面是 html 和 java 脚本代码。

<!DOCTYPE html>

Java脚本代码：

function init() {
	console.log("app started");
	document.getElementById("readings").innerHTML="Starting";
	accelerationSensor=tizen.sensorservice.getDefaultSensor("ACCELERATION");
	if (accelerationSensor){
		console.log("Sensor captured");
	}
	
	
/* Update the clock hands every second */
	accelerationSensor.start(onsuccessCB);
setInterval(function() {
updateTime();
}, 1000);
}
window.onload = init();
function onGetSuccessCB(sensorData)
{
	var datetime = tizen.time.getCurrentDateTime();
	var Date = ("0" + datetime.getHours()).slice(-2)   + ":" + 
("0" + datetime.getMinutes()).slice(-2) + ":" + 
("0" + datetime.getSeconds()).slice(-2);
	console.log(Date);
console.log("######## Get acceleration sensor data ########");
console.log("x: " + sensorData.x);
console.log("y: " + sensorData.y);
console.log("z: " + sensorData.z);

	
x = sensorData.x;
y = sensorData.y;
z = sensorData.z;

tizen.filesystem.resolve("documents", function(dir) 
	    {
	       
	       var newFile = dir.resolve("newFilePath.txt");;
	       newFile.openStream(

	        function(fs) {
	        	 fs.write(Date+"t x:"+x+"t y:"+y+"t z:"+z+"n");
	        	 fs.close();
	        }, function(e) {
	        	 console.log("Error " + e.message);
	        }, "UTF-8");
	    },function(){

	    });
document.getElementById("readings").innerHTML="Reading";
}
function onerrorCB(error)
{
console.log("error occurred: " + error.message);
}
function onsuccessCB()
{
console.log("acceleration sensor start");
var datetime = tizen.time.getCurrentDateTime();

	        	 fs.close();
	        }, function(e) {
	        	 console.log("Error " + e.message);
	        }, "UTF-8");
	    },function(){
	    	document.getElementById("readings").innerHTML="Error";
	    });
}
function updateTime() {

	
	accelerationSensor.getAccelerationSensorData(onGetSuccessCB, onerrorCB);
}
(function () {
	window.addEventListener("tizenhwkey", function (ev) {

提前谢谢。

我已经设法找到了解决方案，我发布它是为了帮助其他将面临相同问题的人。

事实证明，S3中没有加速度传感器，当我将传感器从加速度更改为linear_acceleration时，一切正常。html 和 javascript 的代码如下：

<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width,user-scalable=no">

<link rel="stylesheet" href="lib/tau/wearable/theme/default/tau.min.css">

<!-- load theme file for your application -->
<link rel="stylesheet" href="css/style.css">

<body>
<div class="ui-page ui-page-active" id="main">

<h2 class="ui-title">TAU Basic</h2>
</header>
<div class="ui-content ui-content-padding">

</div>
<script src="lib/tau/wearable/js/tau.min.js"></script>
<script src="js/app.js"></script>
<script src="js/lowBatteryCheck.js"></script>
<script src="js/circle-helper.js"></script>
</body>
</html>

javascript：

var accelerationSensor;
function onsuccessCB() {
console.log("acceleration sensor start");
var datetime = tizen.time.getCurrentDateTime();
var hour = datetime.getHours();
var minute = datetime.getMinutes();
var second = datetime.getSeconds();
tizen.filesystem.resolve("documents", function(dir) {
var newFile = dir.createFile("newFilePath.txt");
newFile.openStream(
"w",
function(fs) {
fs.write(hour + ":" + minute + ":" + second + "tstart of recording n");
fs.close();
document.getElementById("readings").innerHTML = "Reading";
},
function(e) {
document.getElementById("readings").innerHTML = "File Error";
}, "UTF-8");
});
}
function init() {
console.log("app started");
document.getElementById("readings").innerHTML = "Starting";
accelerationSensor = tizen.sensorservice.getDefaultSensor("LINEAR_ACCELERATION");
document.getElementById("readings").innerHTML = "Starting1";
if (accelerationSensor) {
console.log("Sensor captured");
document.getElementById("readings").innerHTML = "Acceleration";
} else {
document.getElementById("readings").innerHTML = "Error";
}
/* Update the clock hands every second */
accelerationSensor.start(onsuccessCB);
document.getElementById("readings").innerHTML = "onsuccessCB done";
console.log("onsuccessCB done");
setInterval(function() {
updateTime();
}, 1000);
}
window.onload = init();
function onGetSuccessCB(sensorData) {
var datetime = tizen.time.getCurrentDateTime();
var Date = ("0" + datetime.getHours()).slice(-2) + ":" +
("0" + datetime.getMinutes()).slice(-2) + ":" +
("0" + datetime.getSeconds()).slice(-2);
console.log(Date);
console.log("######## Get acceleration sensor data ########");
console.log("x: " + sensorData.x);
console.log("y: " + sensorData.y);
console.log("z: " + sensorData.z);
var x = sensorData.x;
var y = sensorData.y;
var z = sensorData.z;
tizen.filesystem.resolve("documents", function(dir) {
var newFile = dir.resolve("newFilePath.txt");
newFile.openStream(
"a",
function(fs) {
fs.write(Date + "t x:" + x + "t y:" + y + "t z:" + z + "n");
fs.close();
},
function(e) {
console.log("Error " + e.message);
}, "UTF-8");
}, function() {
document.getElementById("readings").innerHTML = "Error";
});
document.getElementById("readings").innerHTML = "Reading";
}
function onerrorCB(error) {
console.log("error occurred: " + error.message);
}
function updateTime() {
	accelerationSensor.getLinearAccelerationSensorData(onGetSuccessCB);
}
(function() {
window.addEventListener("tizenhwkey", function(ev) {
var activePopup = null,
page = null,
pageid = "";
if (ev.keyName === "back") {
activePopup = document.querySelector(".ui-popup-active");
page = document.getElementsByClassName("ui-page-active")[0];
pageid = page ? page.id : "";
if (pageid === "main" && !activePopup) {
try {
tizen.application.getCurrentApplication().exit();
} catch (ignore) {}
} else {
window.history.back();
}
}
});
}());

上面的代码将获取linear_acceleration传感器读数，并将它们保存到"文档"文件夹中的文本文件中。您需要 filesystem.read 和 filesystem.write 权限才能访问"文档"文件夹。
