Test your app works on popular devices

One of the reasons more than a billion users love Android is that they can choose the device that’s right for them from a huge range of models. This can make it hard to test on all the device models that are popular with your users before release. Remember that thoroughly tested apps are more likely to get better reviews and make more money. Google can help with tools that help you implement more comprehensive and accessible testing strategies.

The pre-launch report in the Google Play Console summarizes issues found by tests of your alpha or beta apps run on popular devices using Firebase Test Lab for Android. You can also opt to use Firebase Test Lab to access highly configurable testing, additional functionality, and more detailed reporting to ensure your app meets your user's expectations.

Why it works

By ensuring that your apps or games work on the most popular devices, you reduce the risk of significant issues being discovered after release and adversely affecting your apps’ ratings. It also provides you with the opportunity to identify any devices you might need to exclude from your release.

Best practices

  • Enable the pre-launch report in the Play Console.
  • Use pre-launch report diagnostics to help you fix any crashes detected in pre-launch reports, and identify any layout issues or security vulnerabilities.
  • Test and optimize your app on physical devices and emulators. Your users will own a range of devices and it’s important that you have diversity in your testing mix.
  • Prioritize your testing devices. You don’t have to test on every device available. Focus on major manufacturers and ensure a diversity in screen size, processor, and device memory.
  • Test under realistic user conditions. Make sure to test your app on different networks, locations, and device orientations.
  • Create a meaningful test plan. Think through the critical paths in your app and ensure those are verified every time there is a new build. You can also use the Firebase Test Lab for Android Robo Test, an intelligent crawler that navigates your app automatically and reports crashes and provides screenshots so you can spot errors before users do.
  • Write test scripts where possible. Prioritize scripts for core functionality and parts of your app that aren’t changed often.
  • Integrate physical device testing into your continuous integration process, ideally stopping builds if they fail critical paths in your app.
  • Review the data received from tests and look beyond app functionality. Stability, network performance, and client-side lag are also critical.
