BONUS: What are the best developer options for Android

Other than enabling development in your Android device, the developer options provide additional tools that can help you out during development.

Here is a list of the most frequently used developer options:

  1. Input > Show taps

This option will display a visual feedback when a touch is detected. Useful when you are recording screen recordings or demos.

  1. Input > Pointer location

Enabling this will display the screen coordinates of any touch input detected. Useful when debugging UI.

  1. Drawing > Show layout bounds

Displays the bounds of each view, so that you can debug spacing, margins, and UI.

  1. Drawing > Force RTL layout direction

Changes the layout from Left-to-Right to Right-to-Left so that you can test your application in languages without changing the system language.

  1. Drawing > X animation scale

Changes the duration of animations. You can set the scale to x10 in order to dramatically slow down animations and debug your transitions and animations.

Setting them to x0 will disable animations entirely.

  1. Hardware accelerated rendering > Debug GPU overdraw

Overdraw is when your app draws pixels on the screen that are never displayed to the end users. This might be because you are placing multiple Views on top of each other. This option will display:

  • 🔵 a blue color for 1x Overdraw (best)
  • 🟢 a green color for 2x Overdraw
  • 🌸 a pink color for 3x Overdraw
  • 🔴 a red color for 4x Overdraw (worst).
  1. Hardware accelerated rendering > Simulate color space

Changes the colors of the device in order to simulate a color space such as Monochromacy or Deuteranomaly (red-green).

  1. Monitoring > Profile GPU rendering

Reports the GPU rendering happening on the screen. The 'On screen as bars' option will display bars on the screen every time new frames are pushed to the screen. When the bars pass the horizontal line, it means that the frame took longer than the benchmark 16.67ms per frame.

  1. Apps > Don't keep activities

Finishes each activity every time onStop() is called. This is useful when you want to simulate the event where Android terminates your application due to memory constraints.

Conclusion

Enabling the developer options in your device is enabled by tapping on the 'Build number' in your device 7 times in a row. This option can be found in different places depending on the manufacturer and Android version of the device. The developer settings allow you to debug your application and include various helpful developer tools.
