WebView on Lollipop won't work but it works on Kitkat

My WebView works fine on Kitkat and lower API levels, but on Lollipop my WebView is in an infinite loading state. How to fix it to work on Lollipop too?

This is error that is showing:

E/SysUtils: ApplicationContext is null in ApplicationStatus...
E/chromium: [ERROR:browser_gpu_channel_host_factory.cc(258)] Failed to init browser shader disk cache...
E/libEGL: validate_display:255 error 3008 (EGL_BAD_DISPLAY)
