olivierg基本上是对的(AudioSource仍然可以是MIC),一些基本的代码将如下所示：
am = (AudioManager) getSystemService(Context.AUDIO_SERVICE);
registerReceiver(new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
int state = intent.getIntExtra(AudioManager.EXTRA_SCO_AUDIO_STATE, -1);
Log.d(TAG, "Audio SCO state: " + state);
if (AudioManager.SCO_AUDIO_STATE_CONNECTED == state) {
/*
* Now the connection has been established to the bluetooth device.
* Record audio or whatever (on another thread).With AudioRecord you can record with an object created like this:
* new AudioRecord(MediaRecorder.AudioSource.MIC, 8000, AudioFormat.CHANNEL_CONFIGURATION_MONO,
* AudioFormat.ENCODING_PCM_16BIT, audioBufferSize);
*
* After finishing, don't forget to unregister this receiver and
* to stop the bluetooth connection with am.stopBluetoothSco();
*/
unregisterReceiver(this);
}
}
}, new IntentFilter(AudioManager.ACTION_SCO_AUDIO_STATE_CHANGED));
Log.d(TAG, "starting bluetooth");
am.startBluetoothSco();
这个我再次偶然发现,我想指出,插槽评论的重要性包括正确的权限,最重要的是设置
在你的清单文件.没有它,您将不会收到任何错误信息,但状态将不会更改为连接.
