在 Android 中尝试使用 BluetoothSocket.connet() 时，A2DP 会下降

因此，我正在使用利用 A2DP、HFP、AVRCP 和 SPP 的硬件设备。我遇到的问题似乎只出现在某些手机上，但我想解决它。

通过 Android (pair.connect) 连接硬件设备时，一切正常。如果我进入默认音乐播放器，它会正确播放并且 AVRCP 命令正常工作。

然而，在我正在开发的应用程序中，我使用 SPP。当我尝试使用 BluetoothSocket.connet() 方法时，它会导致硬件丢失 A2DP 和 AVRCP（媒体连接），我正在使用蓝牙聊天示例中的标准 bluetoothSerialService 类

private static final UUID SerialPortServiceClass_UUID = UUID.fromString("00001101-0000-1000-8000-00805F9B34FB");

...

mmSocket = mmDevice.createRfcommSocketToServiceRecord(SerialPortServiceClass_UUID);
mmSocket.connect();

无法工作的手机，我am 测试包括 Droid X (2.2/2.3)、HTC Desire 2.2、Droid1 2.2。它适用于 Samsung Captivate 2.2 和 LG Optimus One 2.2

So I am working with a hardware device that utilizes A2DP, HFP, AVRCP, and SPP. The problem I am getting seems to be only on some phones but I want to resolve it.

While connecting the hardware device through Android (pair.connect) everything works fine. If I go into a default music player it streams correctly as well as AVRCP commands working.

However, in the app I am working on I use SPP. And when I try to use the BluetoothSocket.connet() method it causes the hardware to lose A2DP and AVRCP (media connections) I am using the standard bluetoothSerialService class from the Bluetooth Chat example

private static final UUID SerialPortServiceClass_UUID = UUID.fromString("00001101-0000-1000-8000-00805F9B34FB");

...

mmSocket = mmDevice.createRfcommSocketToServiceRecord(SerialPortServiceClass_UUID);
mmSocket.connect();

The phones that don't work and I am testing include Droid X (2.2/2.3), HTC Desire 2.2, Droid1 2.2. And it works on Samsung Captivate 2.2 and LG Optimus One 2.2
