私の単純なオーディオ ストリーミング アプリは 1.6 では完全に動作し、2.1 は 2.2 では動作しません。理由はわかりません。エミュレーターでは問題なく動作しますが、実際の 2.2 デバイスでは、オーディオは約 10 分後に予期せず停止します。携帯電話 (HTC EVO) で logcat を見ると、次のように表示されます。

I/HTTPStream(   65): 1358 Bytes read, progress 34346/65536
I/HTTPStream(   65): 1358 Bytes read, progress 35704/65536

I/HTTPStream(   65): 1358 Bytes read, progress 46571/65536

そして突然：

E/HTTPStream(   65): recv failed, errno = 11 (Try again)

コードは基本的に、Google 自身のドキュメント「Playing from a file or stream」( http://developer.android.com/guide/topics/media/index.html ) から直接作成されています。

ここでも、1.6 と 2.1、および 2.2エミュレーターでは完全に動作しますが、2.2デバイスでは上記のように失敗します。

これは私を夢中にさせています、何かアイデアはありますか？ありがとう。

編集:これは、実行時の私の電話のlogcatの別の例であり、突然の受信がすべて失敗し、サーバーが「なくなった」:

繰り返しますが、1.6 と 2.1 および 2.2エミュレーターでは正常に動作しますが、2.2デバイス、特に私の HTC EVO 4G では失敗します。これは、信号が良好な Wi-Fi を使用していることに注意してください。
