Android Phonegap+；本地存储提升错误

我正在尝试使用phonegap和localStorage创建一个应用程序，它在iOS上运行良好，但在Android上我遇到以下错误：“sqlite返回：错误代码=14，msg=无法打开[42537b6056]第27205行的文件”

我正在寻找答案（谷歌搜索：），但没有成功

下面是代码和堆栈跟踪

先谢谢你

            // Wait for Cordova to load
        document.addEventListener("deviceready", onDeviceReady, false);

        function onDeviceReady() {
            customers = {
                "data" : [
                    {
                        "name" : "Myself"
                    }
                ]
            }
            navigator.notification.alert(customers.data[0].name);
            window.localStorage.setItem("customers", JSON.stringify(customers));

            var retrievedCustomers = window.localStorage.getItem("customers");
            c = JSON.parse(retrievedCustomers);
            console.log(c);
            navigator.notification.alert(c.data[0].name);

        }

您发布的代码看起来不错。我最近创建了一个带有localstorage选项的phonegap应用程序，唯一的区别是我使用了

localstorage.setItem

而不是

window.localstorage.setItem

从错误消息中，您无法猜测确切的错误是什么。JavaScript是一种很难调试的语言，尤其是在移动应用程序中。对我来说，最有效的方法是注释掉几行代码，看看应用程序在没有几行代码的情况下是否可以正常工作（实际上，它是以另一种方式工作的，首先注释掉你怀疑的所有代码，验证应用程序是否正常工作，然后开始取消注释，每次2-3行，看看应用程序是否仍在工作）。一旦找到确切的原因，就更容易修复。

您需要通过添加日志消息更仔细地调试它…一个建议是设置，然后在不同的事件中获取数据…谢谢。我也这么做了，并且一行一行地重写了所有内容，效果很好。谢谢你的提示。我一行一行地重写，应用程序运行良好。
