measureInWindow returns an incorrect Y coord on Android

Description

Measuring an Android View using NativeMethodsMixin.measureInWindow returns the incorrect Y coordinate. It seems it always subtracts 24 (I guess it’s the StatusBar height) from the Y coordinate. It returns the correct value on iOS.

Environment

Environment:

• OS: macOS High Sierra 10.13.4
• Node: 9.9.0
• Yarn: 1.5.1
• npm: 6.0.1
• Watchman: 4.6.0
• Xcode: Xcode 9.3.1 Build version 9E501
• Android Studio: 2.3 AI-162.4069837

Packages: (wanted => installed)

• react: 16.3.1 => 16.3.1
• react-native: ~0.55.2 => 0.55.4

Steps to Reproduce

Create a new app using CRNA/Expo and change App.js like this:

/* @flow */
import * as React from "react";
import { StyleSheet, View, findNodeHandle } from "react-native";
// $FlowFixMe
import NativeMethodsMixin from "NativeMethodsMixin";

class AndroidMeasureTester extends React.Component<{}> {
  boxRef: ?View = null;

  handleBoxLayout = () => {
    if (this.boxRef) {
      NativeMethodsMixin.measureInWindow.call(
        findNodeHandle(this.boxRef),
        (x, y, width, height) => {
          console.debug("RED BOX LAYOUT:");
          console.debug("x", x);
          console.debug("y", y);
          console.debug("width", width);
          console.debug("height", height);
        }
      );
    }
  };

  render() {
    return (
      <View style={styles.container}>
        <View
          style={styles.box}
          ref={ref => (this.boxRef = ref)}
          onLayout={this.handleBoxLayout}
        />
      </View>
    );
  }
}

const styles = StyleSheet.create({
  container: {
    flex: 1,
    height: "100%",
    width: "100%"
  },
  box: {
    width: 80,
    height: 80,
    backgroundColor: "red"
  }
});

export default AndroidMeasureTester;

I also create an Expo Snack.

Expected Behavior

The measured Y coordinate should be 0 (it’s printed on console):

x: 0
y: 0
width: 80
height: 80

Actual Behavior

The measured Y coordinate is -24 (it’s printed on console):

x: 0
y: -24
width: 80
height: 80
