Google engineers also visited us on-site to profile and optimize Fortnite, helping us to identify key optimizations, a memory leak, and also to work out a solid frame pacing implementation for OpenGL on Android. We also worked with Samsung to create the most seamless and secure installation process possible for users of Samsung phones.

Using instrumented test phones and their in-house engineering tools, they were able to give us insight into what our performance and memory bottlenecks were and how to address them. Samsung sent engineers to multiple Epic offices worldwide and worked directly with our engineers on optimizations and performance analysis, and contributed many code changes especially for the Vulkan renderer.

We worked closely with Samsung to profile and optimize Fortnite for their devices. Without their knowledge, expertise, and hard work it would not have been possible.

Working with partners has been crucial to bringing Fortnite to Android.

While much of our work to make this possible was spent on rendering performance, stability and memory, the sheer number and variety of Android hardware, OS versions, and driver versions was the major hurdle we had to overcome. Since January 2018 we have been hard at work with a significant team on the Android version of FNBR. In Fortnite, Android players can be in the same match with their friends on PC and console, so we must render everything that affects gameplay. For instance, you might cull objects closer to the camera to reduce draw calls. Usually, when trying to scale a game down for mobile devices, you simplify the content and even design, in order to fit within the performance constraints of the platform. Shipping the same game across all platforms while supporting cross-play presented a unique challenge. While we are in an invite-only phase for Android, our conversion from players being invited to playing is similar to that of the iOS beta. In the first 21 days since the Fortnite’s launch on Android, interest has been extremely high, with over 23 million players entering our Android beta and over 15 million players installing our APK. Let’s dive into the technical details behind the launch, what we’re working on and where we see Android in the near future. We’ve learned a lot from the beta with regards to performance, security, device compatibility and providing Fortnite on Android through the Fortnite Installer.

A few days later, we began issuing invitations to a subset of Android device owners across a variety of handset manufacturers. On August 9th we launched the Android Beta of Fortnite on select devices from our partners at Samsung. Topics include Hardware Optimization, Performance, Security, and more. Epic Games has released a Blog Post detailing the technicalities of bringing Fortnite to the Android Mobile Platform.
