A fork of an old android-rs-glue crate, compatible with building miniquad-based projects.

Supported [package.metadata.android] entries

# The target Android API level.
# "android_version" is the compile SDK version. It defaults to 29.
# (target_sdk_version defaults to the value of "android_version")
# (min_sdk_version defaults to 18) It defaults to 18 because this is the minimum supported by rustc.
android_version = 29
target_sdk_version = 29
min_sdk_version = 26

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

# The following values can be customized on a per bin/example basis. See multiple_targets example
# If a value is not specified for a secondary target, it will inherit the value defined in the `package.metadata.android`
# section unless otherwise noted.

# The Java package name for your application.
# Hyphens are converted to underscores.
# Defaults to rust.<target_name> for binaries. 
# Defaults to rust.<package_name>.example.<target_name> for examples.
# For example: for a binary "my_app", the default package name will be "rust.my_app"
# Secondary targets will not inherit the value defined in the root android configuration.
package_name = "rust.cargo.apk.advanced"

# The user-friendly name for your app, as displayed in the applications menu.
# Defaults to the target name
# Secondary targets will not inherit the value defined in the root android configuration.

# Internal version number used to determine whether one version is more recent than another. Must be an integer.
# Defaults to 1
# See https://developer.android.com/guide/topics/manifest/manifest-element

# The version number shown to users.
# Defaults to the cargo package version number
# See https://developer.android.com/guide/topics/manifest/manifest-element

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

# Virtual path your application's icon for any mipmap level.
# If not specified, an icon will not be included in the APK.

# If set to true, makes the app run in full-screen, by adding the following line
# as an XML attribute to the manifest's <application> tag :
#     android:theme="@android:style/Theme.DeviceDefault.NoActionBar.Fullscreen
# Defaults to false.

# The maximum supported OpenGL ES version , as claimed by the manifest.
# Defaults to 2.0.
# See https://developer.android.com/guide/topics/graphics/opengl.html#manifest

# Adds extra arbitrary XML attributes to the <application> tag in the manifest.
# See https://developer.android.com/guide/topics/manifest/application-element.html

"android:hardwareAccelerated" = "true"

# Adds extra arbitrary XML attributes to the <activity> tag in the manifest.
# See https://developer.android.com/guide/topics/manifest/activity-element.html
"android:screenOrientation" = "unspecified"
"android:uiOptions" = "none"

# Adds a uses-feature element to the manifest
# Supported keys: name, required, version
# The glEsVersion attribute is not supported using this section. 
# It can be specified using the opengles_version_major and opengles_version_minor values
# See https://developer.android.com/guide/topics/manifest/uses-feature-element

# Adds a uses-permission element to the manifest.
# Note that android_version 23 and higher, Android requires the application to request permissions at runtime.
# There is currently no way to do this using a pure NDK based application.

Environment Variables

Cargo-apk sets environment variables which are used to expose the appropriate C and C++ build tools to build scripts. The primary intent is to support building crates which have build scripts which use the cc and cmake crates.

  • CC : path to NDK provided clang wrapper for the appropriate target and android platform.
  • CXX : path to NDK provided clang++ wrapper for the appropriate target and android platform.
  • AR : path to NDK provided ar
  • CXXSTDLIB : c++ to use the full featured C++ standard library provided by the NDK.
  • CMAKE_TOOLCHAIN_FILE : the path to the generated CMake toolchain. This toolchain sets the ABI, overrides any target specified, and includes the toolchain provided by the NDK.
  • CMAKE_GENERATOR : Unix Makefiles to default to Unix Makefiles as opposed to using the CMake default which may not be appropriate depending on platform.
  • CMAKE_MAKE_PROGRAM: Path to NDK provided make.

C++ Standard Library Compatibility Issues

When a crate links to the C++ standard library, the shared library version provided by the NDK is used. Unfortunately, dependency loading issues will cause the application to crash on older versions of android. Once lld linker issues are resolved on all platforms, cargo apk will be updated to link to the static C++ library. This should resolve the compatibility issues.
