Unable to start activity ComponentInfo java.lang.RuntimeException: Failed to create webview

Question

I am working on ionic v1 project.My problem is - after updating the android platform version to latest - 8.0.0, the app crashes on launch.

Getting this error on logcat-

java.lang.RuntimeException: Unable to start activity ComponentInfo{com.tv.gpd/com.tv.gpd.MainActivity}: java.lang.RuntimeException: Failed to create webview.

I am using this command to add latest android platform-

ionic cordova platform add android@latest

I did some digging and found some solutions and I tried it-

1)Add below line of code in proguard-custom.txt

# These clases contain references to cordova webView
-keep class com.ionicframework.cordova.webview.** {*; }
-keep class com.ionicframework.cordova.webview.*

2)Also checked it by downgrading the "cordova-plugin-ionic-webview" plugin to - 1.2.1 previously webview version is - 2.3.2

I am working with -

Ionic 3.19.0
Cordova CLI 7.0.0
Cordova-Android 8.0.0

Any help will be appreciated as I need to make app to support Android latest - Oreo and Pie version.

Thanks

You have to do this also If your project uses WebView with JS, uncomment the following and specify the fully qualified class name to the JavaScript interface

-keepclassmembers class android.webkit.WebView {
   public *;
}
