Tell me please. What webview do you use for android?
Crosswalk Project is completed 9 months ago. Also it has a problem it is impossible to forbid the input of characters because Google has removed this feature for the virtual keyboard. So masks don’t work.
Gekko webview from Mozilla is very old.
Another one webview x5 also is very old.
I didn’t other webview.
Maybe you write your own webview?)
What is wrong with the default one?
