[英]Android : How to disconnect already connected bluetooth device?
I have connect function and it works perfect我已经连接了 function 并且效果很好
fun connect(btDevice: BluetoothDevice?) {
val id: UUID = btDevice?.uuids?.get(0)!!.uuid
val bts = btDevice.createInsecureRfcommSocketToServiceRecord(id)
bts?.connect()
}
But bts.close()
doesnt`t works, if i call this one但是bts.close()
不起作用,如果我调用这个
D/BluetoothSocket: close() this: android.bluetooth.BluetoothSocket@518c676, channel: 2, mSocketIS: android.net.LocalSocketImpl$SocketInputStream@d48a477, mSocketOS: android.net.LocalSocketImpl$SocketOutputStream@51478e4mSocket: null, mSocketState: CLOSED
Kotlin Kotlin
private fun disconnect(device: BluetoothDevice) {
val serviceListener: BluetoothProfile.ServiceListener = object :
BluetoothProfile.ServiceListener {
override fun onServiceDisconnected(profile: Int) {}
@SuppressLint("DiscouragedPrivateApi")
override fun onServiceConnected(profile: Int, proxy: BluetoothProfile) {
val disconnect = BluetoothA2dp::class.java.getDeclaredMethod(
"disconnect",
BluetoothDevice::class.java
)
disconnect.isAccessible = true
disconnect.invoke(proxy, device)
BluetoothAdapter.getDefaultAdapter().closeProfileProxy(profile, proxy)
}
}
BluetoothAdapter.getDefaultAdapter()
.getProfileProxy(this, serviceListener, BluetoothProfile.A2DP)
}
