We have now three of these classes with similar functionality. It would be nice
if you could extract the common things to a base class, something like

class AndroidBrowserBase extends Browser {
  static const String viewAction = 'android.intent.action.VIEW';

  AdbDevice _adbDevice;

  AndroidBrowserBase(this._adbDevice);

  Future<bool> close() {
    ...
  }
}

You can keep the 'start()' method (although they're a bit redundant as well).

I'm not comfortable modifying AndroidChrome since I can't test it locally, but
I've refactored DartiumOnAndroid and ContentShellOnAndroid to eliminate
redundancies. I'll commit for now, but there is more cleanup possible, so
further comments are certainly welcome.
