Question

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上我收到以下错误：“sqlite返回：错误代码= 14，msg =无法打开第27205行的文件[42537b6056]”。

我正在寻找答案（谷歌搜索:) :)但没有成功。

代码和堆栈跟踪如下。

提前谢谢。

            // 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);

        }

Answer 1

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localStorage.setItem代替window.localStorage.setItem。

从错误消息中，您无法猜出确切的错误是什么。 JavaScript是一种难以调试的语言，尤其适用于移动应用。对我有用的方法主要是通过注释掉代码行，看看应用程序是否正常工作而没有一些行（实际上它以另一种方式工作，注释掉你首先怀疑的所有代码并验证应用程序是否正常工作，而不是开始取消注释线条，一次2-3个，看看应用程序是否仍在运行）。一旦找到确切的罪魁祸首，就更容易解决。

Phonegap + localStorage引发错误
