Manifest

cargo supports the metadata table for configurations for external tools like cargo apk. Following configuration options are supported by cargo apk under [package.metadata.android]:

[package.metadata.android]
# Specifies the package property of the manifest.
package = "com.foo.bar"

# Specifies the array of targets to build for.
build_targets = [ "armv7-linux-androideabi", "aarch64-linux-android", "i686-linux-android", "x86_64-linux-android" ]

# Path to your application's resources folder.
# If not specified, resources will not be included in the APK.
resources = "path/to/resources_folder"

# Path to the folder containing your application's assets.
# If not specified, assets will not be included in the APK.
assets = "path/to/assets_folder"

# Name for final APK file.
# Defaults to package name.
apk_name = "myapp"

# `default` (or unspecified) - Debug symbols, if they exist, are not treated
#                              specially.
#
# `strip`                    - Debug symbols are stripped from the shared
#                              libraries before being copied into the APK.
#
# `split`                    - Functions the same as `strip`, except the debug
#                              symbols are written to the apk output directory
#                              alongside the stripped shared libraries, with
#                              a `.dwarf` extension.
#
# Note that the `strip` and `split` options will only have an effect if
# debug symbols are present in the `.so` file(s) produced by your build, enabling
# https://doc.rust-lang.org/cargo/reference/profiles.html#strip or
# https://doc.rust-lang.org/cargo/reference/profiles.html#split-debuginfo
# in your cargo manifest can cause debug symbols to no longer be present
# in the `.so`.
strip = "default"

# Folder containing extra shared libraries intended to be dynamically loaded at runtime.
# Files matching `libs_folder/${android_abi}/*.so` are added to the apk
# according to the specified build_targets.
runtime_libs = "path/to/libs_folder"

# The name of a Linux user ID that is shared with other apps. By
# default, Android assigns each app its own unique user ID. However, if
# this attribute is set to the same value for two or more apps, they all
# share the same ID, provided that their certificate sets are identical.
# Apps with the same user ID can access each other's data and, if
# desired, run in the same process.
shared_user_id = "my.shared.user.id"

# Defaults to `$HOME/.android/debug.keystore` for the `dev` profile. Will ONLY
# generate a new debug.keystore if this file does NOT exist. A keystore is never
# auto-generated for other profiles.
#
# The keystore path can be absolute, or relative to the Cargo.toml file.
#
# The environment variables `CARGO_APK_<PROFILE>_KEYSTORE` and
# `CARGO_APK_<PROFILE>_KEYSTORE_PASSWORD` can be set to a keystore path
# and keystore password respectively. The profile portion follows the same rules
# as `<cfg>`, it is the uppercased profile name with `-` replaced with `_`.
#
# If present they take precedence over the signing information in the manifest.
