cordova media android不播放声音,Cordova Media Plugin录制音频错误

我使用Cordova媒体插件构建了一个Android应用程序来录制音频 .

当我按下录制按钮时，它会创建一个音频文件 .

重新编码完成后：

如果按后退按钮，则音频文件为空 .

如果按主页键转到该位置，则音频文件正常并可播放 .

使用后退按钮时如何解决此问题？

.controller('myController', function($scope, $ionicPlatform, $cordovaMedia,$cordovaDevice , $timeout, $interval) {

$scope.timerWithInterval = 0;

//$ionicPlatform.ready(function() {

try {

$scope.timerWithInterval = 0;

var mediaRec;

$scope.startRecord = function() {

$scope.timerWithInterval = 0;

if($scope.myInterval){

$interval.cancel($scope.myInterval);

}

$scope.onInterval = function(){

$scope.timerWithInterval++;

}

$scope.circle = "outer-circle-active";

$scope.myInterval = $interval($scope.onInterval,1000);

var random = Math.floor((Math.random() * 100000) + 1);

var src = "myrecording_"+random+".mp3";

$scope.mmediaRec = new Media(src,

// success callback

function(e) {

console.log("recordAudio():Audio Success");

},

// error callback

function(err) {

console.log("recordAudio():Audio Error: "+ err.code);

});

// Record audio

$scope.mmediaRec.startRecord();

};

$scope.stopRecord = function() {

$scope.timerWithInterval = 0;

$interval.cancel($scope.myInterval);

$scope.staus = "successfully saved";

$scope.mmediaRec.stopRecord();

mediaRec.release();

};

} catch (e) {

console.warn("onDeviceReady error: " + e)

alert("onDeviceReady error: " + e);

}

//});

})
