fixes #18493 We enabled `hermes` for android in the `react-native` upgrade to `0.72.5` Although things seemed fine but developers were seeing frequent crashes in their local environment. After some investigation the crashes were traced to max native call stack depth in `hermes` engine. Disabling `hermes` for local debug builds helps fix that issue. This commit disables `hermes` by default with the help of a exporting an environment variable in the `make run-android` command. It is annoying that this also modifies `android/gradle.properties` so we keep `hermesEnabled` as `false` there as well. We also enable `hermes` when generating release builds so that we can take advantage of `hermes` engine in release builds. We also add a log to print whether `hermes` is enabled or not. I think its helpful to have this so that we know whether `hermes` is enabled or not. |

Description
This folder contains configuration for Nix, a purely functional package manager used by the Status app for its build process.
Configuration
The main config file is nix/nix.conf
and its main purpose is defining the binary caches which allow download of packages to avoid having to compile them yourself locally.
Build arguments
We leverage the environment variables for parameterization of the builds (e.g. to pass a build number or build type).
Here is the list of variables you can use to override defaults:
# Build type (influences which .env file gets used for feature flags)
export BUILD_TYPE="pr"
# Used for versionCode and CFBundleVersion in Android and iOS respectively
export BUILD_NUMBER=9999
# Gradle options passed for Android builds
export ANDROID_GRADLE_OPTS=""
# If APKs should be split based on architectures
export ANDROID_ABI_SPLIT=false
# Android architectures to build for
export ANDROID_ABI_INCLUDE="x86"
# Local source override, see below
export STATUS_GO_SRC_OVERRIDE="$HOME/my/source/status-go"
export STATUS_GO_IPFS_GATEWAY_URL="https://ipfs.status.im/"
You can see the defaults in code:
Shell
In order to access an interactive Nix shell a user should run make shell
.
The Nix shell is started in this repo via the nix/scripts/shell.sh
script, which is a wrapper around the nix-shell
command and is intended for use with our main Makefile
. This allows for an implicit use of nix-shell
as the default shell in the Makefile
.
Normally the shell starts without any specific target platform, if you want to change that you should export the TARGET
env variable with appropriate value:
make shell TARGET=android
This way your shell and all other nix commands should run in a setup that is tailored towards Android development.
For valid values you can check the nix/shells.nix
file.
⚠️ WARNING: To have Nix pick up all changes a new nix-shell
needs to be spawned.
Using a local status-go repository
If you need to use a locally checked-out status-go repository, you can achieve that by defining the STATUS_GO_SRC_OVERRIDE
environment variable:
export STATUS_GO_SRC_OVERRIDE=$GOPATH/src/github.com/status-im/status-go
make release-android
