Hello Oboe is an Android sample that uses the Oboe library to play audio natively. Oboe wraps both AAudio and OpenSLES to help developers play and record audio in performance sensitive contexts across Android versions. The Oboe repository has more information about how to fully take advantage of the Oboe API, as well as more in-depth examples and documentation.
