科尔多瓦（安卓）。最小化应用程序时禁用音频播放答案

【问题标题】：Cordova (Android). Disable audio play when application is minimized科尔多瓦（安卓）。最小化应用程序时禁用音频播放

【问题描述】：

启动时，声音开始，最小化时不要停止。我能怎么做？通过

 document.addEventListener("pause", onPause, false); 
 document.addEventListener("resume", onResume, false);

不能。 Pause Event Listener 做不到。帮助。抱歉英语不好。

附注要求写很多

var app = {
    initialize: function () {
        this.bindEvents();
    },
    bindEvents: function () {
        document.addEventListener('deviceready', this.onDeviceReady, false);
    },
    onDeviceReady: function () {
        app.receivedEvent('deviceready');

        var myMedia = new Media("/android_asset/www/audio/sample.mp3")
        myMedia.play({
            playAudioWhenScreenIsLocked: false
        });
    },

    receivedEvent: function () {

    }
};

app.initialize();

【解决方案1】：

您必须将Pause Event Listener 添加到您的应用程序中，以便在它进入后台时进行监听。

document.addEventListener("onDeviceReady", function() {

    // Adds pause event
    document.addEventListener("pause", manageAppPause);

    // Adds resume event
    document.addEventListener("resume", manageAppResume);
});


function manageAppPause() {

    // Check if audio is playing
    // If it is, pause it
}


function manageAppResume() {

    // If you want, check if the audio was playing before the app was put into background
    // If so, resume audio
}

【讨论】：

不——你实际上必须在 manageAppPause 中输入你需要的任何代码才能真正暂停正在播放的任何音频......
这样做了：function manageAppPause() { audioElement.pause(); } 功能 manageAppResume() { audioElement.play(); } }
检查它并在 manageAppPause 中添加一个 console.log("Paused") 以确保该事件实际上正在触发

【解决方案2】：

var app = {
    initialize: function () {
        this.bindEvents();
    },
    bindEvents: function () {
        document.addEventListener('deviceready', this.onDeviceReady, false);
        
    },
    onDeviceReady: function () {
        var myMedia = new Media("/android_asset/www/audio/sample.mp3")
        myMedia.play({
            playAudioWhenScreenIsLocked: false
        });
        document.addEventListener('pause', onPause, false);
        document.addEventListener('resume', onResume, false);
        function onPause() {
            myMedia.pause();
        };
        function onResume() {
            myMedia.play();
        };
    },

};

app.initialize();
