bluetooth 相关问题

如何在我的 VOIP 应用程序中接收蓝牙颈带播放暂停事件？我在应用程序中实现了下面的广播接收器。清单文件如何在我的 VOIP 应用程序中接收蓝牙颈带播放暂停事件？我在应用程序中实现了下面的广播接收器。清单文件 <uses-permission android:name="android.permission.BLUETOOTH" /> <uses-permission android:name="android.permission.BLUETOOTH_CONNECT" /> <uses-permission android:name="android.permission.BLUETOOTH_ADMIN" /> <receiver android:name=".MediaButtonReceiver" android:exported="true" android:priority="10000" > <intent-filter > <action android:name="android.intent.action.MEDIA_BUTTON" /> </intent-filter> </receiver> public class MediaButtonReceiver extends BroadcastReceiver { @Override public void onReceive(Context context, Intent intent) { android.util.Log.d("TAG", "Bluetooth onPlay: "+intent.getAction()); if (Intent.ACTION_MEDIA_BUTTON.equals(intent.getAction())) { KeyEvent event = intent.getParcelableExtra(Intent.EXTRA_KEY_EVENT); if (event != null && event.getAction() == KeyEvent.ACTION_DOWN) { int keyCode = event.getKeyCode(); if (keyCode == KeyEvent.KEYCODE_MEDIA_PLAY || keyCode == KeyEvent.KEYCODE_MEDIA_PAUSE) { // Handle play/pause event } } } } } 并像这样注册到调用活动 MediaButtonReceiver r = new MediaButtonReceiver(); registerReceiver(r, new IntentFilter(Intent.ACTION_MEDIA_BUTTON)); 并且还在应用程序中的广播接收器下面实现了 public class BluetoothHeadsetReceiver extends BroadcastReceiver implements BluetoothProfile.ServiceListener { private static final String TAG = "BluetoothHeadsetReceiver"; private BluetoothHeadset bluetoothHeadset; @Override public void onServiceConnected(int profile, BluetoothProfile proxy) { if (profile == BluetoothProfile.HEADSET) { bluetoothHeadset = (BluetoothHeadset) proxy; Log.d(TAG, "Bluetooth Headset connected"); } } @Override public void onServiceDisconnected(int profile) { if (profile == BluetoothProfile.HEADSET) { bluetoothHeadset = null; Log.d(TAG, "Bluetooth Headset disconnected"); } } @Override public void onReceive(Context context, Intent intent) { String action = intent.getAction(); Log.d(TAG, "Bluetooth Headset onReceive : "+action); if (BluetoothHeadset.ACTION_CONNECTION_STATE_CHANGED.equals(action)) { int state = intent.getIntExtra(BluetoothHeadset.EXTRA_STATE, BluetoothHeadset.STATE_DISCONNECTED); if (state == BluetoothHeadset.STATE_CONNECTED) { Log.d(TAG, "Bluetooth Headset connected"); } else if (state == BluetoothHeadset.STATE_DISCONNECTED) { Log.d(TAG, "Bluetooth Headset disconnected"); } } else if (BluetoothHeadset.ACTION_AUDIO_STATE_CHANGED.equals(action)) { int state = intent.getIntExtra(BluetoothHeadset.EXTRA_STATE, BluetoothHeadset.STATE_AUDIO_DISCONNECTED); if (state == BluetoothHeadset.STATE_AUDIO_CONNECTED) { Log.d(TAG, "Bluetooth Headset audio connected"); // Handle button click events or other actions here } else if (state == BluetoothHeadset.STATE_AUDIO_DISCONNECTED) { Log.d(TAG, "Bluetooth Headset audio disconnected"); } }else{ Log.d(TAG, "Bluetooth Headset onReceive else : "); } } public void register(Context context) { BluetoothAdapter bluetoothAdapter = BluetoothAdapter.getDefaultAdapter(); if (bluetoothAdapter != null) { bluetoothAdapter.getProfileProxy(context, this, BluetoothProfile.HEADSET); IntentFilter filter = new IntentFilter(); filter.addAction(BluetoothHeadset.ACTION_CONNECTION_STATE_CHANGED); filter.addAction(BluetoothHeadset.ACTION_AUDIO_STATE_CHANGED); context.registerReceiver(this, filter); } else { Log.e(TAG, "Bluetooth is not supported on this device"); } } public void unregister(Context context) { context.unregisterReceiver(this); if (bluetoothHeadset != null) { BluetoothAdapter.getDefaultAdapter().closeProfileProxy(BluetoothProfile.HEADSET, bluetoothHeadset); } } } 在调用 Activity OnCreate() 方法中注册以下代码。 MediaButtonReceiver r = new MediaButtonReceiver(); registerReceiver(r, new IntentFilter(Intent.ACTION_MEDIA_BUTTON)); if(gc.hasBTPermission(this, ConstantStrings.BLUETOOTH_PERMISSION)) { if (BluetoothManager.getInstance().isBluetoothHeadsetAvailable()) { headsetReceiver = new BluetoothHeadsetReceiver(); headsetReceiver.register(this); BluetoothManager.getInstance().initBluetooth(); } } 但不接收蓝牙耳机播放，暂停点击事件仅接收应用程序中的蓝牙连接和断开事件。我想基于蓝牙点击事件呼叫接受和挂断呼叫，但不在应用程序中接收事件。蓝牙 HID 配置文件/服务始终由设备的底层操作系统处理。只需订阅操作系统的关键事件即可。在 Android 中，应用程序可以通过覆盖 MediaSession.Callback.onMediaButtonEvent(Intent) 来覆盖默认行为。在这种情况下，应用程序可以/需要自行处理所有 API 细节。

在 Android 上禁用“蓝牙权限请求”确认 - 使用 ACTION_REQUEST_DISCOVERABLE

我正在尝试将我的Android手机作为蓝牙服务器进行广播，为此，我首先想让Android“可发现”。我使用 ACTION_REQUEST_DISCOVERABLE 来执行此操作，如下所示： http://
