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：“返回的sqlite：错误代码= 14，msg =无法在[42537b6056]的第27205行打开文件”。

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。

先感谢您。

            // 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，我能看到的唯一区别是我使用localStorage.setItem了window.localStorage.setItem.

From the error message, you cannot guess what the exact error is. JavaScript is difficult language to debug especially with mobile apps. The approach that works for me mostly is by commenting out lines of code and see if the app works fine without some lines (actually it works the other way, comment out all the code you suspect first and verify the app is working, than start uncommenting lines, 2-3 at a time and see if the app is still working). Once you find out the exact culprit, it is easier to fix.
