What you get with Cordova is simply a JavaScript API, which serves as a wrapper for native code and is consistent across devices. In essence, Cordova has no limitations in relation to natively developed applications. This Apache Cordova review and tutorial will examine Cordova app development in more detail, and while some of it may apply to PhoneGap, this shouldn’t be considered a PhoneGap tutorial, per se. With time, Adobe PhoneGap developed its own set of proprietary features, while Cordova was-and still is-supported by the open-source community. Obviously, the differences between Cordova and PhoneGap were minimal in the beginning. A common analogy you will often run into is that Cordova is to PhoneGap what WebKit is to Chrome or Safari. What happened was, Adobe acquired Nitobi in 2011, and donated the open-source core to the Apache Software Foundation, who rebranded it Apache Cordova. In Nitobi’s vision, most mobile applications would soon be developed using PhoneGap, but developers would still have the option of writing native code when necessary, be it due to performance issues, or lack of a method of accessing specific hardware. In 2009, a startup called Nitobi created PhoneGap, an open source API for accessing native mobile resources, with the goal of enabling developers to create mobile applications using standard web technologies. This is where becoming a well-versed Apache Cordova developer can come in handy by providing a way to develop mobile applications using standard web technologies-HTML5, CSS3, and JavaScript. However, developing for each separate mobile platform can be an exhaustive task, especially if your resources are limited, or if you are a single developer rather than a mobile app development company. Window.resolveLocalFileSystemURL(: Since this was originally written, I've updated this article to work with and applications are creeping in everywhere, starting with smartphones and tablets, to smart watches, and soon be found in other wearables, too. If you want to go deeper in file-system API, I suggest to read, besides the mandatory Cordova man page, two great articles and. Type this: cordova plugins add cordova-plugin-file Exporting the database to a backup fileĪll right! We can finally type some code, now! First we'll write the function which actually exports our database and writes down a mysql dump file: put the follwing code before the jQuery main function. You should still have your terminal (or command prompt) open in your project root directory (if not, then open it and go there). To do so we're going to install an important cordova plugin which is used to read and write files within the host OS. Managing files: cordova-plugin-fileīut files must be managed: we have to create them and their directories, we must be able to read their content and to write content to files. So, open your command prompt o your terminal window and navigate to your project root, then type: cordova plugin add uk.co. To import a databse you can use the correspondent functions importJsonToDb() and importSqlToDb(). You can export the database to a json file or to a sql file using exportDbToJson() and exportDbToSql() functions. SQLite Porter allow you to export and import a database using just a few lines of code. The plugin is fantastic, it works great and let me share with you I'm proud indeed to have joined the contributors group fixing a small bug which prevented to successfully use exportDbToSql() and importDbFromSql(). Here we'll see how to manage backup and restore of a database using a helpful plugin: SQLite Porter by Dave Alden. Wellcome to the second part of my tutorial about how to save your database to Dropbox from within a Cordova mobile application.
