It looks like this pull request may not have tests. Please make sure to add tests or get an explicit test exemption before merging. If you are not sure if you need tests, consider this rule of thumb: the purpose of a test is to make sure someone doesn't accidentally revert the fix. Ask yourself, is there anything in your PR that you feel it is important we not accidentally revert back to how it was before your fix? Reviewers: Read the Tree Hygiene page and make sure this patch meets those guidelines before LGTMing. If you believe this PR qualifies for a test exemption, contact "@test-exemption-reviewer" in the #hackers channel in Discord (don't just cc them here, they won't see it!). The test exemption team is a small volunteer group, so all reviewers should feel empowered to ask for tests, without delegating that responsibility entirely to the test exemption group. |

Code Review
This pull request correctly suppresses a deprecation warning for AChoreographer_postFrameCallback which is necessary for compatibility with Android API 35. The use of _Pragma is appropriate for use within a macro. I have one suggestion to improve the portability of this change by adding compiler guards around the Clang-specific pragmas, which would make the code more robust if it were ever compiled with a different toolchain.

Other than the note flagged about this being clang specific (with a suggested workaround), this LGTM. |

Oof, the clang-format seems really weirded out by the macros. Perhaps just // clang-format off for that block? Let me know if you'd rather I take over landing the patch. |

@chinmaygarde Done! Added // clang-format off/on around the macro block. |

AChoreographer_postFrameCallback is deprecated in Android API 35, but we still need to support it for devices running API levels 24-28. The code already uses AChoreographer_postFrameCallback64 when available on API 29+. This change suppresses the deprecation warning to allow building against API 35 while maintaining backward compatibility. Fixes flutter#173656

Description
This PR fixes a build error when compiling Flutter's Impeller engine against Android API 35. The deprecated
AChoreographer_postFrameCallbackAPI causes a fatal compilation error, but is still required for backward compatibility with Android devices running API levels 24-28.The fix adds compiler pragma directives to suppress the deprecation warning without changing runtime behavior. The code continues to:
AChoreographer_postFrameCallback64on API 29+ devices (newer, recommended API)AChoreographer_postFrameCallbackon API 24-28 devices (legacy support)This approach follows the recommendation from @chinmaygarde in the issue comments.
