Android WebView: Secure Coding Practices


This is part one of a three-part series. Click here to read part two.There is no doubt that mobile applications have changed the world in a bigway. Just look at interaction habits, for example, the way people socialize asindividuals or in a group has changed as what was once far away is now at ourfingertips. There is an infinite number of applications and resourcesavailable to millions of users. And as these numbers grow, security concernsraise as well.Everything nowadays is all about connectivity and delivering a great, secureand transparent browsing capability. With this in mind, web-based content canbe embedded into Android applications using a resource called WebView. Usingthis component brings many functionalities, but it can also be a huge risk.That is why assuring WebView secure coding is so important.WebView is a system component that allows Android apps to display content fromthe web directly inside an application, creating the concept of hybrid apps.An app can be Native, Hybrid, or Web (HTML5).A Native app has to be installed on the device, as the Web app runs on thebrowser with no need for installation. The Native approach will use theoperating system’s supported language, which in Android’s case is Java(Objective-C/Swift in iOS systems, C

It is the next step of app development, It brings the paceand power of a native app with the clarity and simple of an web app. It’sdeveloped by Emberify founded by Shashwat Pradhan. Instant 4.0 was launched on13th July 2016 with a Chatbot Coach.Using an Android Instant App is analogous to browsing to a web page. Once youclose up the window, it disappears. With Android Instant app, people can usean app or game without installing it first. The Android Instant App is a smallsoftware program that enables end users to test out a portit of a nativeAndroid application without installing it on the device. Android Instant appsdo not take up storage on the device. Instant apps are relatively easy to makeand do not require additional skills.

Features of Android Instant Apps :


• Android Instant apps give daily and weekly reports based on the user’stracked data. All the data stays only on the user’s device.• Instant app also can connect to the user’s Android Wear smartwatch and AppleWatch.• It allows Android users to run their apps instantly, without installation.• Users can get native Android experience from any URL—including messaging,search, social media, and other deep links with no need to install your appfirst.• You can use an app without needing to fully download it onto your phone.App developers often struggle to increase the visibility of an app as it isburied within the App Store. More applications will be added to the InstantApps lineup in the future, but as of right now, the list of supported apps ispretty short. Do you have a favourite Instant app?

Android WebView vulnerability


WebView is an Android view that is used in order to display web content in anapplication. It uses the WebKit rendering engine in order to display web pagesand other content with the file:// and data:// protocols, which could be usedto load files and data content from the filesystem. WebView is used in variousAndroid applications as well, which display the web content in theapplication, such as applications offering signup and login, by framing theirmobile website in the application’s layout. We will be discussing more aboutWebKit and its rendering engine in the next chapter. For this chapter, we willonly be concerned about those applications that use WebKit.

The way forward


One of Google’s most common business strategies is to develop two competingproducts and see which one wins out in the end — Progressive Web Apps andInstant Apps, Allo and Android Messages, and so on. The two environments forcreating applications on Chrome OS, Android and the web, is seemingly anotherexample of this. They’re achieving the same goal, but taking different routes.Google wants to adapt desktop web applications to work on touch screens, whilealso tweaking smartphone/tablet Android apps to work on desktops.We’ve already covered how Progressive Web Apps are becoming more and morepowerful. They can work offline, have different interfaces for differentscreen sizes, send notifications, sync data in the background, and so on. Aproperly-designed PWA works significantly better on Chrome OS than the sameapp written for Android — you’ll know what I mean if you’ve ever tried TwitterLite instead of the Twitter Android app.If the Chrome OS team leaned a little harder into PWAs, the benefit for usersand developers alike could be massive. The Chrome Web Store should berevamped, with a focus on highlighting modern web apps. Google could addpopular applications and sites to the store automatically, just like whatMicrosoft is doing with the Windows Store. Instead of being a library ofabandoned Chrome-specific packaged apps, it should be a showcase of the bestPWAs on the web — with an install button for each.Chromebooks shine the brightest when used for their original purpose —browsing the web and using cloud-based applications. I’m glad the Play Storeis available, because the promise of an all-web future isn’t quite here yet,but I think Google could do a bit more to make that future happen.Check out the new Android PoliceWe’ve got a new look, hope you like itRead NextAbout The AuthorCorbin Davenport (3633 Articles Published)Corbin is a tech journalist and developer who worked at Android Police from2016 until 2021.
