// The NDK marks an API unavailable whenever it is newer than the API level the build targets, and
|
||
|
|
// fastfetch keeps running on devices below the levels it uses: AImageDecoder is 30, decoding past
|
||
|
|
// the first frame is 31, and AMediaCodec_getName is 28. CMake compiles the files that reach for
|
||
|
|
// them with -D__ANDROID_UNAVAILABLE_SYMBOLS_ARE_WEAK__ -Werror=unguarded-availability, which turns
|
||
|
|
// those entry points into weak references and makes every unguarded use an error. Two things follow:
|
||
|
|
//
|
||
|
|
// * A weak reference resolves to null on an older device, so every use needs a run-time check --
|
||
|
|
// that is FF_API_AT_LEAST. Unguarded, the call would jump to a null pointer.
|
||
|
|
// * Annotating a helper with FF_REQUIRES_API keeps the check in one place: the compiler rejects
|
||
|
|
// any call of that helper which is not itself inside a guard.
