Alternatively use the shake gesture:

Clicking on the menu button in the Genymotion Android simulator
You can use this menu to enable/disable live reloading, hot reloading, component inspector, etc.
This option allows you to debug your JavaScript code in Google Chrome. The code is executed in a Chrome tab you have access to all the usual devtools such as: debugger statements, break-points, console logging, etc.
Using console.warn will display an on-screen log on a yellow background. Click on this warning to show more information about it full screen and/or dismiss the warning. Place
console.disableYellowBox = true;in the root component to temporarily disable warnings
You can use console.error to display a full screen error on a red background.
