This doesn't work well on CI as files are re-downloaded at every CI run. If you follow the approach mentioned in the previous paragraph, you should be able to parallelize the native build on 4 different ABIs and you will most likely not need ccache on CI.Ĭcache relies on timestamps to compute a cache hit. On CI, we recommend to do a full clean build, to avoid poisoned cache problems. However, there are a couple of things to be aware: Therefore you could save & restore the corresponding folder also on CI to speedup your builds. Using this approach on a CI Ĭcache uses the /Users/$USER/Library/Caches/ccache folder on macOS to store the cache. More on this can be found in the official ccache manual. The same may be configured in a nf file or any other mechanism ccache provides. To confirm that this approach is working fine, you'll see a message like info Detected architectures arm64-v8a on console. This flag will make sure the correct ABI is picked up from either the running emulator or the plugged in phone.

If you're using the React Native CLI, you can use the -active-arch-only flag together with the run-android command. This should reduce your build time by a ~75% factor. However, you probably don't need to build all of them if you're building locally and testing your emulator or on a physical device. When building your android app locally, by default you build all the 4 Application Binary Interfaces (ABIs) : armeabi-v7a, arm64-v8a, x86 & x86_64. Build only one ABI during development (Android-only) To mitigate this performance hit, this page shares some suggestions on how to improve your build time. With the New React Native Architecture, this problem is becoming more criticalĪs you might have to compile some native C++ code in your project with the Android NDK in addition to the native code already necessary for the iOS and Android platforms. This can be problematic as your project grows and generally in bigger organizations with multiple React Native developers. Building your React Native app could be expensive and take several minutes of developers time.
