Question

我使用ionic-framework / cordova来构建我的应用。我已安装此插件cordova-plugin-background-mode以便在后台模式下工作。

问：但是现在我怎样才能完成在后台每30分钟重复一次的任务？

你知道另一个插件吗？

Answer 1

根据您使用的存储库，代码必须如下所示：

// Run when the device is ready
document.addEventListener('deviceready', function () {

    // Android customization
    // To indicate that the app is executing tasks in background and being paused would disrupt the user.
    // The plug-in has to create a notification while in background - like a download progress bar.
    cordova.plugins.backgroundMode.setDefaults({ 
        title:  'TheTitleOfYourProcess',
        text:   'Executing background tasks.'
    });

    // Enable background mode
    cordova.plugins.backgroundMode.enable();

    // Called when background mode has been activated
    cordova.plugins.backgroundMode.onactivate = function () {

        // Set an interval of 30 minutes (1800000 milliseconds)
        setInterval(function () {

            // The code that you want to run repeatedly

        }, 1800000);
    }
}, false);

您可以使用$timeout和$interval执行此任务，但需要一段时间
