Android builds will honor the `ANDROID_API_LEVEL` environment variable to set the
minimum supported [API level](https://developer.android.com/tools/releases/platforms)
for generated wheels. This will default to the minimum API level of the selected Python
version.
If the [`repair-wheel-command`](options.md#repair-wheel-command) adds any libraries to
the wheel, then `ANDROID_API_LEVEL` must be at least 24. This is already the default
when building for Python 3.14 and later, but you may need to set it when building for
Python 3.13.
for generated wheels. This defaults to 24, which is supported by [99% of active
devices](https://dl.google.com/android/studio/metadata/distributions.json), and is the first
version to support RUNPATH, which auditwheel needs in order to graft external libraries.
