Our mobile application belongs to hybrid category. That means some core features operates with the help of WebView component which is a wrapper around installed mobile web browser. In a case of Android this is based on Chromium browser.
With newer devices (from Android 7) you should be fine as long as system apps are updated. Depending on Android build and from device to the device one should update one of these apps from Google Play Store.
WebView component comes in three flavors (package names):
- com.android.webview (non updateable)
- com.google.android.webview (System Web View Updateable from Google Play)
- com.android.chrome (Chrome Browser Updateable from Google Play)
As this version is not updateable from Google Play, what can we do? Is there a solution?
Well, actually there is.
It might still not work on some devices so take this workaround with grain of salt.
Solution is to manually download custom build com.android.webview apk file and install it on your device. This action will update default device provided version with newer library which might enable our application to work on such devices.
Simply download version 66 of Androd System WebView to your mobile device from here. Then click on downloaded file to install it.
Note: On some devices, manual install should be enabled through system settings. More details here. Or you can search the web for the term "android sideload" to find out more information how to do it.
Which WebView version ?
To check which WebView version you have, update Green Screens Mobile Application to at least Version 3.8.0. Build 188. Then go to the Settings, scroll to About where you should see WebView version and package name.
