A lot of us have seen this Android System WebView somewhere on our phones. It could be in your settings or among your apps. You might notice it during System Updates on your phone. You may be wondering what it is used for. Why is it on your phone? What is its purpose?
We know you've got questions. That is why we have looked far and wide to bring you these answers. Here is what you need to know about this app.
Android System WebView is like the Chrome App. In Chrome, you have access to any app that has a web version. You do not need to leave Chrome to visit their link. For example, Twitter, Instagram, Facebook, Asana, all of your favorite apps can all be viewed on the chrome component. No features are lost. The Android System WebView has similar features, except it is of a smaller version. It allows you to view links to websites and other apps inside it. So it as though you had a mini-browser within the app.
Not every app supports this feature. For this reason, certain apps may open on Chrome instead. The System WebView comes pre-installed on all Android devices. On your phone it is an app. But if you are using Android 7.0 Nougat or a higher Android version, you will not see the app on your phone. This is because Google incorporated it into the Google Chrome.
Yes, you do!! The System WebView is very beneficial to your device, especially if it is Android. Apart from displaying in-app web content, instead of redirecting you to chrome, it has a lot of other functions as well:

1. You can control the User interface of all your applications with much ease. Plus it is way better!!
2. The app updates itself automatically. Unlike other apps, you won't receive notification updates every few weeks. You also won't experience the disturbance in usage all because you have not upgraded to the latest version.
3. There are no third-party involvements when using the app. If there is a link to another site, the app opens that link right where you are. Instead of directing you to another tab. No need to leave your site to go to another one.
4. It makes cross-platform development easier for app developers. This reduces the cost of producing an app.
There are many other reasons why the Android WebView is needed on your system. Normally, you shouldn't remove, or uninstall it from your system. This is because a lot of apps need it to work on your phone. When you remove it, certain systems may not function as normal anymore.
When developing your app, it is important to incorporate the System WebView into it. Adding a browser feature to your app increases its value. You do this by including WebView Library. You also need to:
· Create a WebView class to incorporate the browser unto the app.
· Add your Java Script.
· In the Manifest file, also add Internet permission and the WebView code. This will enable you open a Web page within your app.
You also need to test your WebView properly, to ensure it performs well.
· Go to the app you want to develop
· Interrupt the webpage when it is loading. Ensure that it is giving the correct response when interrupted. E.g. Like it would behave, if there were no internet.
· Ensure that all hyperlinks open within your app. For example, if you have a hyperlink for messages, or a phone number, ensure the messenger or phone app opens up when you click on it. When your customers want to use the app, all hyperlinks will be working fine.
· Check how well the WebView responds to all network modes, including Wi-Fi, LTE, 3G and 2G.
· Check the user-friendliness of the UI and Navigation. This includes zooming in & zooming out, scroll up/down feature, menu icon, speed of use, etc. It also includes the graphic design and the easiness on the eyes, accessibility to relevant information.
· Check the compress-ability of the text, font and design of your app browser. Is it responsive on different devices, does it easily adapt to different screen sizes?
· Apply all these tests using a cross browser platform. It will show you how the WebView will look like from the customer's point of view. You can easily perform these tests over here.
Espresso Web is a great tool for testing your System WebView. It examines the behaviour of the WebView app for you. It great for testing Hybrid applications (such as Instagram). Hybrid applications are apps that open up links to other websites in their own app, using the help of Android System WebView. For example, Instagram can open up links to websites like Etsy and Blogs without the need to leave the app itself. Espresso Web lets you see how well your app is performing using this feature. For compound Websites, you may need to further analyse the source code before using this too, to prevent complications.
Aside the source code, you can use the Android Device Monitor. When viewing a website through the Android System WebView, some parts may be inaccessible. This is because they have no ID. The Android Device Monitor will show you these inaccessible areas, using a UI. You will need to take a screenshot of each screen. On your own, map out the internal structure of the app. The UIAutomator tool lets you map it out easily.
Uninstalling the app is very possible. However, you can only do it on the Android 7.0 Nougat, or higher versions. These versions already have a replacement. Its system webview is runs on Chrome. You can disable the app using the settings on your phone.
· Go to the Google Play App on your device
· Click on the hamburger icon.
· It will take you to 'My Apps & Games'. Click on it
· There are grouped icons of "Installed", "Updates" and "Library"
· Click 'Installed'. Scroll down till you see Android System WebView. Open it
· It will show you the page on Android System WebView. Click "Uninstall"
For non-Android Nougat users and above, if is safer for you to uninstall the updates. But you can't uninstall the app. But if you are currently experiencing a problem with your Android System WebView, here is how you can fix it:
Google recently released the System Webview as a separate, lone app so it can automatically update itself. When the automatic updates in the settings of your Google Play store is turned on, it updates along with other apps. However, when it is turned off in the settings, it can no longer update. Your will have an outdated app on an upgraded system. This can cause problems, and could be the reason it is not working properly. If that is the case, you need to update the app to the latest version available. You can do this when Google play store. On the Menu icon, you will see a 'My apps and Games' Select it. Under the Updates icon, click on Android System Webview App. Select 'Update '. Then install the app. Reboot your phone to ensure it is back to normal. Also turn on the update settings so it can do so automatically.
Sometimes, the saved data stored in the app can accumulate and cause our apps to stop functioning properly. This is the case for other apps on our phones. To solve this problem, you need to reset the whole app. By resetting the app, you are wiping away unnecessary data that has been stored on your device. This makes the app to restart on a clean, fresh slate for you. The app should be working fine after that. Here is how to do so:
· Click on the Settings app in your device.
· Select Apps/Mange Apps. You will be shown the list of apps you have on your device.
· Click on the menu button. It is usually at the top right of the screen. It will show you the full list of all apps on your device.
· Search for the Android System Webview among this list. Click on it.
· You will see two icons; 'Clear Data' and 'Clear All Data' respectively. Click on each, one after the other. This erases all unnecessary data on your phone.
· When you are done, go back and reboot your system. Check any apps that have been malfunctioning. See if you still have the same problems. Your system Webview should be working fine by now.
Here is everything you need to know about the Android System WebView App. From owners of devices to developers, we hope we answered all questions you have. There is still more to it. But it is for the masters of techie stuff. They don't even speak English (a slang, meaning their tech vocabulary is out of this world!!).You might not understand it. Hope you enjoyed learning about this gray app. You now know of this priced knowledge. Thank you for staying with us. Do have an amazing day!!
