Fixed problem with saving images in Android sample #24622 Fixes https://github.com/opencv/opencv/issues/24590 Current code for saving images in Android sample worked only on very old phones. Added support for modern Android versions. Required: - https://github.com/opencv/ci-gha-workflow/pull/127 - https://github.com/opencv-infrastructure/opencv-gha-dockerfile/pull/27
