OpenSL ES Audio Playerから完成したバッファーを解放する必要がありますか？

Question

確認のために

。AndroidのOpenSL ESを介して作成されたオーディオプレーヤーが、バッファの再生を終了すると、そのバッファはガベージコレクタによって自動的に解放されますか？それとも私自身を解放する必要がありますか？

後者の場合は、私はいくつかの助けを使うことができました。しかし今のとおり、私が自分でやる必要があると言われるまで私はコードを投稿しません...

Answer 1

The buffer queue doesn't actually allocate buffer memory itself (or need to free it), you pass in pointers to memory you have allocated via the 'enqueue' function. You will need to free the memory you allocated when you're finished playing buffers.

As OpenSL ES is a native library in C++, it knows nothing of garbage collection, any memory you allocate for the API must be freed by you, and objects you create must have 'destroy' called on them to clean up internal memory.

Answer 2

As the previous poster said, you call Enqueue with a buffer you have created previously. I'd point out, however, that unless you're playing only one audio event once in your app, you should probably keep re-using your audio buffers to avoid GC altogether - the beauty of C!

Also check out the Android OpenSL ES doc concerning Destroying your interfaces once your done with them, that has to be done manually.
