私は自分のアンドロイドのサウンドボードを作りました。今、私は 1 つだけ問題があります。曲のイントロがありますが、約 38 秒です。イントロを再生しようとしても、約 20 秒間しか聞こえません。

誰かが私を助けることができますか？

MediaPlayer の代わりに Soundpool を使用している特定の理由はありますか?

このタイプのメディア再生では、MediaPlayer の方がはるかに洗練されています。

サービス (その長さの音楽再生に推奨) またはバックグラウンド スレッドではなく、メイン スレッドでそれを行っている場合、イベント スレッドが長時間ロックされている可能性があります。ちょっとした考え。
