sencha touch与phonegap（使用sencha cmd和phonegap构建）导致错误：LocalFileSystem未定义 [英] sencha touch with phonegap (using sencha cmd and phonegap build) causes Error : LocalFileSystem not defined
问题描述
我按照这些sencha cmd指南，产生一个基于phoneGap的sencha touch 2项目：
使用最新的Sencha Cmd v4.0.2.67，最新sencha触摸2.3.1，phoneGap ver-3.1.0
1）按以下方式制作sencha touch 2项目：
sencha -sdk / path / to / sencha-touch-sdk generate app MyApp / path / to / www / myapp
2）将phoneGap添加到上述项目
sencha phonegap init
3）配置phonegap.local.properties
phonegap.platform = android
phonegap.build.remote = true
phonegap.build.remote.username = myUseName
phonegap .build.remote.password = myPassword
4）更新了配置。添加所有核心插件添加所有核心插件
<
< gap：plugin name =org.apache.cordova.battery-status/>
< gap：plugin name =org.apache.cordova.camera/>
< gap：plugin name =org.apache.cordova.media-capture/>
< gap：plugin name =org.apache.cordova.console/>
< gap：plugin name =org.apache.cordova.contacts/>
< gap：plugin name =org.apache.cordova.device/>
< gap：plugin name =org.apache.cordova.device-motion/>
< gap：plugin name =org.apache.cordova.device-orientation/>
< gap：plugin name =org.apache.cordova.dialogs/>
< gap：plugin name =org.apache.cordova.file/>
< gap：plugin name =org.apache.cordova.file-transfer/>
< gap：plugin name =org.apache.cordova.geolocation/>
< gap：plugin name =org.apache.cordova.globalization/>
< gap：plugin name =org.apache.cordova.inappbrowser/>
< gap：plugin name =org.apache.cordova.media/>
< gap：plugin name =org.apache.cordova.network-information/>
< gap：plugin name =org.apache.cordova.splashscreen/>
< gap：plugin name =org.apache.cordova.vibration/>
并移除了< preference name =permissionsvalue =none /> permission config
5）创建了一个名为dirReader.js的外部js文件， in app.json
dirReader.js内容
window.onerror = function（msg，url，linenumber）{
alert（'错误信息：'+ msg +'\\\
URL：'+ url +'\\\
Line Number：'+ linenumber）
return true
}
var dirList = [{name：'Chart 1'}，{name：'Chart 2'}];
//等待设备API库加载
//
document.addEventListener（deviceready，onDeviceReady，false）;
//设备API可用
//
function onDeviceReady（）{
alert（device ready）;
Ext.device.FileSystem.requestFileSystem（
LocalFileSystem.PERSISTENT，0，function（fs）{// LocalFileSystem未定义错误在这里
alert（Root =+ fs.root.fullPath ）;
var directoryReader = fs.root.createReader（）;
directoryReader.readEntries（function（entries）{
var i;
for（i = 0; i< entries .length; i ++）{
//alert(entries[i].name）;
var itemObj = {};
itemObj.name = entries [i] .name;
dirList.push（itemObj）;
}
var dirListString = JSON.stringify（dirList）;
alert（dirListString）;
}，function（error）{
alert（error.code）;
}）
}，function（error）{
alert（error.code）;
}）;
}
6） 'ext.device.FileSystem' in app.js
7） c> sencha app build native
这会导致在命令提示符（无错误）中发生许多mumbo jumbo。该应用程序被压缩并上传到build.phonegap for android构建。建立成功。
----------------------------- -------------------------------------------------- ---------
PROBLEM >该应用安装并开始正常。
我从dirReader.js文件接收到设备就绪警报。
我得到的下一个错误是 LocalFileSystem未定义在dirReader.js。
我检查了构建的apk包含了所有插件的plugins文件夹，包括 org.apache.cordova.file 。此外，cordova_plugins.js存在，并且具有 window.LocalFileSystem 条目。
我看到了同样的问题.. cordova_plugin.js包含
{
file ：plugins / org.apache.cordova.core.file / www / FileSystem.js，
id：org.apache.cordova.core.file.FileSystem，
clobbers ：[
window.FileSystem
]
}，
您是否尝试使用> cordova build构建android
您可以调用任何其他API方法吗？
I followed these sencha cmd guide to produce a phoneGap based sencha touch 2 project: Using Latest Sencha Cmd v4.0.2.67 , Latest sencha touch 2.3.1 , phoneGap ver- 3.1.0
1) Make a sencha touch 2 project by :
sencha -sdk /path/to/sencha-touch-sdk generate app MyApp /path/to/www/myapp
2) Add phoneGap to the above project
sencha phonegap init
3) configure the phonegap.local.properties
phonegap.platform=android
phonegap.build.remote=true
phonegap.build.remote.username=myUseName
phonegap.build.remote.password=myPassword
4) Updated the config.xml by adding all the core plugins
<!-- Core plugins -->
<gap:plugin name="org.apache.cordova.battery-status" />
<gap:plugin name="org.apache.cordova.camera" />
<gap:plugin name="org.apache.cordova.media-capture" />
<gap:plugin name="org.apache.cordova.console" />
<gap:plugin name="org.apache.cordova.contacts" />
<gap:plugin name="org.apache.cordova.device" />
<gap:plugin name="org.apache.cordova.device-motion" />
<gap:plugin name="org.apache.cordova.device-orientation" />
<gap:plugin name="org.apache.cordova.dialogs" />
<gap:plugin name="org.apache.cordova.file" />
<gap:plugin name="org.apache.cordova.file-transfer" />
<gap:plugin name="org.apache.cordova.geolocation" />
<gap:plugin name="org.apache.cordova.globalization" />
<gap:plugin name="org.apache.cordova.inappbrowser" />
<gap:plugin name="org.apache.cordova.media" />
<gap:plugin name="org.apache.cordova.network-information" />
<gap:plugin name="org.apache.cordova.splashscreen" />
<gap:plugin name="org.apache.cordova.vibration" />
and removed the <preference name="permissions" value="none"/> permission config
5) Created a external js file named dirReader.js and included its path in app.json
dirReader.js Contents
window.onerror=function(msg, url, linenumber){
alert('Error message: '+msg+'\nURL: '+url+'\nLine Number: '+linenumber)
return true
}
var dirList = [{name: 'Chart 1'},{name: 'Chart 2'}];
// Wait for device API libraries to load
//
document.addEventListener("deviceready", onDeviceReady, false);
// device APIs are available
//
function onDeviceReady() {
alert("device ready");
Ext.device.FileSystem.requestFileSystem(
LocalFileSystem.PERSISTENT, 0, function(fs) { // LocalFileSystem not defined error here
alert("Root = " + fs.root.fullPath);
var directoryReader = fs.root.createReader();
directoryReader.readEntries(function(entries) {
var i;
for (i=0; i<entries.length; i++) {
//alert(entries[i].name);
var itemObj = {};
itemObj.name = entries[i].name;
dirList.push(itemObj);
}
var dirListString = JSON.stringify(dirList);
alert(dirListString);
}, function (error) {
alert(error.code);
})
}, function (error) {
alert(error.code);
});
}
6) Added 'Ext.device.FileSystem' in requires under app.js
7) Finally ran sencha app build native
This causes many mumbo jumbo to take place in the command prompt (No Errors) . the app is compressed and uploaded to build.phonegap for android build. Build succeeds.
----------------------------------------------------------------------------------------
PROBLEM
The app installs and starts fine.
I receive the "Device Ready" alert from the dirReader.js file.
The next error I get is that LocalFileSystem is undefined in dirReader.js.
I tried lots of things but nothing works.
I checked that the built apk contains the plugins folder with all the plugins including the org.apache.cordova.file . Also , the cordova_plugins.js is present and has the window.LocalFileSystem entry.
I saw somewhere the same issue.. is the cordova_plugin.js contain
{
"file": "plugins/org.apache.cordova.core.file/www/FileSystem.js",
"id": "org.apache.cordova.core.file.FileSystem",
"clobbers": [
"window.FileSystem"
]
},
did you try build with >cordova build android
can you call to any other API method?
