I have built my own android os for hikey and I have added a new app view package into packages folder and I have rebuilt my system it compile all successfully.
When I have flashed my card I had an exception "E WebViewFactory: Chromium WebView package does not exist" when I have launched my webview application:

Why I have this exception ? did you have a solution?
NOTE: I have in the external folder a chromium-webview and when I check in file system of android I have found :
adb shell
hikey960:/ $ find . -name webview.apk 2> /dev/null
./system/app/webview/webview.apk
