This plugin helps you to prevent the white screen of death for your Cordova/Ionic applications. Different versions of Android come with a different version of Android System WebView installed. Certain JS features work only in newer webview versions, so when a user tries to start a Cordova/Ionic application with an older webview implementation, the JS parser throws an error which will lead to an empty white screen. This plugin can be used to check the available webview version before parsing your main application bundle and show a meaningful error message to the user.
