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:
For full functions refer code snippets below:
Get file path from the persistent storage and send it to the play method.
