Cordova（Android）。当应用程序最小化时禁用音频播放。

Question

Cordova（Android）。当应用程序最小化时禁用音频播放。

8

当启动时，声音开始播放，最小化时不会停止。我该怎么做？通过以下方式：

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

我无法做到。暂停事件监听器无法完成。帮帮我。对不起，我的英语不好。

P.S. 我需要写很多请求

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();

您需要在应用程序中添加一个暂停事件监听器，以便在应用程序进入后台时监听。

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
}
