I am trying to use the audio recording as described in the PhoneGap API documentation. But on IOS there seems to be a problem with the file URI for myrecording.wav. I am using the following code to write to a file named myrecodring.wav
function recordAudio() {
var src = "myrecording.wav";
var mediaRec = new Media(src, onSuccess, onError);
// Record audio
mediaRec.startRecord();
// Stop recording after 10 sec
var recTime = 0;
var recInterval = setInterval(function() {
recTime = recTime + 1;
setAudioPosition(recTime + " sec");
if (recTime >= 10) {
clearInterval(recInterval);
mediaRec.stopRecord();
}
}, 1000);
}
i've also tried file://myrecording.wav and file:///myrecording.wav
i've done my test on ios5 iphone 4gs. I get the failure message with code 1 saying "Cannot use audio file from resource...."
Thanks for you help,
Martin
You have to first get file system:
window.requestFileSystem(LocalFileSystem.PERSISTENT, 0, gotFS, fail);
Then get the file:
function gotFS(fileSystem) {
alert('got FS');
fileSystem.root.getFile("myrecording4.wav", {create: true, exclusive: false}, gotFileEntry, fail);
}
Now you can get the file URI:
function gotFileEntry(fileEntry) {
alert('File URI: ' + fileEntry.toURI());
}

I have been trying to store Audio file in persistent storage for two days without success.
So far I am able to create an audio file which records audio from Microphone (The app has the permission) using the code attached below.
The audio file is getting generated & stored successfully, I can play it.
But the real problem is when I close the app and come back and try to play the file it shows error.
"{"message": "Cannot use audio file from resource '/myrecording.wav'",
"code":1}"
The file is not persistent across app sessions even though I used LocalFileSystem.PERSISTENT.
I am not sure whether the problem is with my Media/Audio code or File storage code.
Please find the code attached below:
Below function records the audio from the microphone.
function _recordAudio() {
var deferred = $q.defer();
var src = "myrecording.wav";
alert("SRC:" + src);
window.requestFileSystem(LocalFileSystem.PERSISTENT, 0, function (fileSystem) {
fileSystem.root.getFile(src, {
create: true,
exclusive: false
}, function (fileEntry) {
alert("File " + src + " created at " + fileEntry.fullPath);
var mediaRec = new Media(fileEntry.fullPath,
function () {
alert("Success");
}, function (error) {
alert("error:" + JSON.stringify(error));
});
// Record audio
mediaRec.startRecord();
// Stop recording after 10 sec
var recTime = 0;
var recInterval = setInterval(function () {
recTime = recTime + 1;
if (recTime >= 5) {
clearInterval(recInterval);
mediaRec.stopRecord();
deferred.resolve(fileEntry.fullPath);
}
}, 1000);
}, function (error) {
alert("getFile error:" + JSON.stringify(error));
deferred.reject();
}); //of getFile
}, function (error) {
alert("requestFileSystem error:" + JSON.stringify(error));
deferred.reject();
}); //of requestFileSystem
return deferred.promise;
}
Below function plays the audio.
function _play2() {
var src = "myrecording.wav";
window.requestFileSystem(LocalFileSystem.PERSISTENT, 0, function (fileSystem) {
fileSystem.root.getFile(src, null, function (fileEntry) {
alert("File " + src + " created at " + fileEntry.fullPath);
var mediaRec = new Media(fileEntry.fullPath,
function () {
alert("Success play2");
}, function (error) {
//Getting error after closing and opening the app
//Error message = {"message": "Cannot use audio file from resource '/myrecording.wav'","code":1}
alert("error play2:" + JSON.stringify(error));
});
mediaRec.play();
});
});
}
I solved this problem by passing cdvfile: path to the Media plugin in PlayAudio function code and copying the file from Temp storage to persistent storage.
I had to use localURL of the file.
This part solved my problem:
fileEntry.file(function (file) {
_playNow(file.localURL);
}
For full functions refer code snippets below:
recordAudio: function (projectNo, ItemNo) {
try {
var deferred = $q.defer();
var recordingTime = 0;
_audioLoader = $("#audioLoader");
_audioLoader.show();
UtilityService.showPopup('audio');
_isRecording = true;
_recordFileName = "Audio_" + projectNo + "_" + ItemNo + ".wav";
_mediaRecord = new Media(_recordFileName);
//Record audio
_mediaRecord.startRecord();
var recordingInterval = setInterval(function () {
recordingTime = recordingTime + 1;
$('#audioPosition').text(_secondsToHms(recordingTime));
if (!_isRecording) {
clearInterval(recordingInterval);
_mediaRecord.stopRecord();
_mediaRecord.release();
deferred.resolve();
}
}, 1000);
//document.getElementById('audioPosition').innerHTML = '0 sec';
$('#audioPosition').text('0 sec');
return deferred.promise;
}
catch (ex) {
alert('WMMCPA|recordAudio:- ' + ex.message);
}
},
Get file path from the persistent storage and send it to the play method.
//To play recorded audio for specific project item
playAudio: function (projectNo, ItemNo) {
try {
_recordFileName = "Audio_" + projectNo + "_" + ItemNo + ".wav";
var newFileUri = cordova.file.dataDirectory + _recordFileName;
window.resolveLocalFileSystemURL(newFileUri, function (fileEntry) {
fileEntry.file(function (file) {
_playNow(file.localURL);
}, function (error) {
alert("WMMCPA|playAudio.file:-" + JSON.stringify(error));
});
}, function (error) {
alert("WMMCPA|playAudio.resolveLocalFileSystemURL:-" + JSON.stringify(error));
});
}
catch (ex) {
alert("WMMCPA|playAudio:-" + ex.message);
}
}
function _playNow(src) {
try {
var mediaTimer = null;
_audioLoader = $("#audioLoader");
_audioLoader.show();
UtilityService.showPopup('audio');
//Create Media object from src
_mediaRecord = new Media(src);
//Play audio
_mediaRecord.play();
} catch (ex) {
alert('WMMCPA|_playNow.mediaTimer:- ' + ex.message);
}
}, 1000);
} catch (ex) {
alert('WMMCPA|_playNow:- ' + ex.message);
I am running into a problem with my cordova app where after an app update, localStorage is cleared. I am now attempting to save some basic user data to a text file instead, using cordova's FileWriter and FileReader.
At some point cordova updated and these methods and now requires a plugin to read and write files: https://cordova.apache.org/docs/en/latest/reference/cordova-plugin-file/index.html
Because my live iOS application uses the old version of cordova, it must write with FileWriter. My app update (not live) uses a newer version of cordova and therefore must use the plugin.
------ Possible workaround found, see update below ------
When trying to read the file, I am seeing the following error in xcode:
017-01-26 17:58:52.990 MyApp[40355:2892997] ERROR: Method 'hello there' not defined in Plugin 'File'
2017-01-26 17:58:52.991 MyApp[40355:2892997] -[CDVCommandQueue executePending] [Line 142] FAILED pluginJSON = ["File1875336264","File","hello there",["cdvfile://localhost/persistent/player_data.txt",null,null]]
Note: I'm running the following code in Safari console while the iOS simulator is running, just for convenience
My code for writing the file
(function() {
var onFail = function(err) {
alert('write action failed!');
alert(err.code);
};
var onGotFS = function(fileSystem) {
alert( 'gotFS' );
fileSystem.root.getFile("player_data.txt", {create: true}, onGotFileEntry, onFail);
};
var onGotFileEntry = function(fileEntry) {
alert( 'gotFileEntry, path: ' + fileEntry.fullPath );
fileEntry.createWriter(onGotFileWriter, onFail);
};
var onGotFileWriter = function(writer) {
alert( 'gotFileWriter' );
writer.onwrite = onFileWritten;
writer.onerror = onFail;
var data = "hello there";
alert( 'writing data: ' + data );
writer.write( data );
};
var onFileWritten = function(evt) {
alert( "saveTokenToFile SUCCESS!" );
};
// start process of looking up file system and writing
alert( 'requesting file system ...' );
window.requestFileSystem(LocalFileSystem.PERSISTENT, 1024, onGotFS, onFail);
})();
My code for reading the file:
(function() {
window.requestFileSystem(LocalFileSystem.PERSISTENT, 0, function (fs) {
fs.root.getFile("player_data.txt", { create: true }, function (fileEntry) {
fileEntry.file(function (file) {
var reader = new FileReader();
reader.onloadend = function() {
alert("Success");
console.log(evt.target.result);
};
reader.onerror = function() {
console.log("reader error");
};
reader.readAsText(file);
}, onErrorReadFile);
});
}, onErrorLoadFs);
var onErrorReadFile = function(){
console.log("error reading file");
}
var onErrorLoadFs = function() {
console.log("request file system has failed to load.");
}
})();
UPDATE
In case anyone else runs into this, I did find a way to read the saved file. The fileEntry object has a URL path to the saved file. To access the data on the file, I'm passing that URL to jQuery.getJSON, which gives us back some readable json.
readDataFromFile: function(){
window.requestFileSystem(LocalFileSystem.PERSISTENT, 0, function (fs) {
fs.root.getFile("player_data.txt", {}, function (fileEntry) {
var entryURL = fileEntry.nativeURL;
jQuery.getJSON(entryURL, function(data) {
console.log(data);
}).fail(function(){
console.log("file found, but contents were empty");
});
}, onErrorGetFile);
}, onErrorLoadFs);
var onErrorLoadFs = function() {
console.log("request file system has failed to load.");
};
var onErrorGetFile = function() {
console.log("requested file can not be read or does not exist");
};
}
I am using media plugin to record sounds.
var my_media = new Media('test.wav');
my_media.startRecord();
my_media.stopRecord() // after few seconds
my_media.release();
my_media.play();//works fine
// But when I try to Check if test.wav file exist I always get false as status.
//File name of our important data file we didn't ship with the app
var fileName = "test.wav";
function init() {
console.log("Checking for data file.");
//Check for the file.
window.resolveLocalFileSystemURL(fileName, onSuccess, onFail);
}
function onSuccess() {
console.log("Great! This file exists");
}
function onFail() {
console.log('Sorry! File not Found');
}
// I always get this message: Sorry! File not Found
What is right way to do this? After recording I want user to be able to see list of available recorded sounds and user should be able to play it. For that I need to check if file exists or not.
So how should we implement that?
You can display list of recorded files as:
window.requestFileSystem(LocalFileSystem.PERSISTENT, 0, function(fileSystem) {
fileSystem.root.getDirectory(YOUR_PATH, {
create: true
}, function(directory) {
root_path = fileSystem.root.toURL();
var directoryReader = directory.createReader();
directoryReader.readEntries(function(entries) {
var i;
for (i = 0; i < entries.length; i++) {
//Get file URL as: entries[i].toURL()); & display using creating dynamic tag.
}
}, function(error) {
alert(error.code);
});
});
}, function(error) {
alert("can't even get the file system: " + error.code);
});
I am busy upgrading a Phonegap app from 3.3 to 3.5 everything works so far but the file download, opening isn't working
function downloadFile(url, filename, fail, downloadDone) {
window.fail = fail;
window.downloadDone = downloadDone;
window.requestFileSystem(LocalFileSystem.PERSISTENT, 0, function onFileSystemSuccess(
fileSystem) {
var fileTransfer = new FileTransfer();
fileTransfer.download(url, window.filePath + filename, function(theFile) {
window.downloadDone();
}, function(error) {
window.fail(error);
});
}, window.fail);
}
function setupFilePath(callBack) {
window.callback = callBack;
window.requestFileSystem(LocalFileSystem.PERSISTENT, 0, function onFileSystemSuccess(
fileSystem) {
fileSystem.root.getFile("dummy.html", {
create: true,
exclusive: false
}, function gotFileEntry(fileEntry) {
var sPath = fileEntry.root.replace("dummy.html", "");
window.filePath = sPath;
var fileTransfer = new FileTransfer();
fileEntry.remove();
dataDir = fileSystem.root.getDirectory(sPath + 'cordapp', {
create: true
});
window.filePath = sPath + 'cordapp/';
console.log("FILE PATH IS: " + window.filePath)
callBack()
}, null);
}, null);
}
Getting the error that the app can't create the directory what am I doing wrong? Is there also a way to not letting it backup to iCloud?
i am developing a phonegap project in mac os with xcode. in xcode if i create a cordova based application it automatically creates cordova-1.6.0.js. i am using fileupload plugin for sending svg file to my server. in fileupload.js i have written alert fileuplaoder function as following,
var FileUploader = function() {
alert("gi");
}
this alert is working, but when i give the aler under upload function,
FileUploader.prototype.upload = function(server, file, params, fileKey, fileName, mimeType, success, fail, progress) {
alert("upload");
this._doUpload('upload', server, file, params, fileKey, fileName, mimeType, success, fail, progress);
};
this alert is not working. my call for this plugin in html page is,
window.plugins.fileUploader.upload('http:192.168.1.54:8080/downloadFiles', '/Users/User/Library/Application Support/iPhone Simulator/5.0/Applications/408DBBC7-67F7-4E8B-B41C-663CDC0377B5/Documents/image5_1.jpg.txt.svg', {foo: 'bar'}, 'myPhoto', 'image5_1.jpg.txt.svg', 'image/svg',
function(result) {
console.log('Done: ' + result);
},
function(result) {
console.log("Error: " + result);
},
function(loaded, total) {
var percent = 100 / total * loaded;
console.log('Uploaded ' + percent);
}
);
in fileupload.js there is cordova.addConstructor method. but in my generated cordova.1.6.0.js file there is no such method. i dont know whats happening. pl help me to work this plugin.
i found the solution. there is a upload and download options in the cordova file api itself. its working fine. the code is,
document.addEventListener("deviceready", onDeviceReady, false);
// Cordova is ready
//
function onDeviceReady() {
window.requestFileSystem(LocalFileSystem.PERSISTENT, 0, gotFS, fail);
}
function gotFS(fileSystem) {
fileSystem.root.getFile("image5_2.jpg.svg", {create: true, exclusive: false}, gotFileEntry, fail);
}
function gotFileEntry(fileEntry) {
var localpath=fileEntry.fullPath;
uploadPhoto(localpath);
//fileEntry.createWriter(gotFileWriter, fail);
}
function uploadPhoto(imageURI) {
alert(imageURI);
var options = new FileUploadOptions();
options.fileKey="file";
options.fileName="image5_2.jpg.svg";
options.mimeType="image/svg+xml";
var params = new Object();
params.value1 = "test";
params.value2 = "param";
options.params = params;
var ft = new FileTransfer();
ft.upload(imageURI, "http://192.168.1.54:8080/POC/fileUploader", win, fail, options);
}
function win(r) {
console.log("Code = " + r.responseCode);
console.log("Response = " + r.response);
console.log("Sent = " + r.bytesSent);
}
function fail(error) {
alert("An error has occurred: Code = " + error.code);
console.log("upload error source " + error.source);
console.log("upload error target " + error.target);
}
pl use this.
