Getting errors when using newer version of Android sdk

[micky2be]

Sadly in my apps I need a newer sdk than the version 19.
While everything works fine on a 4.4.2 device I get the following error on a 5.0.2 device:

Any idea how I could fix it?
Having the source of WebView+ could help

+1 on this, getting the same error on Android 5.x when using WebView+

+1, cordova/phonegap app not installing on lollypop build with WebView+

[MayankLogiciel]

does creators of WebView+ stopped supporting this project?
