在进行程序化配对时，如何避免或关闭 Android 的蓝牙配对通知? [英] How can I avoid or dismiss Android's Bluetooth pairing notification when I am doing programmatic pairing?

问题描述

我有一个应用程序，我可以在其中以编程方式控制蓝牙配对和取消配对.我可以在连接前配对并在连接后取消配对.我需要这样做的原因特定于我的应用程序，而不是我的问题范围.

I have an app where I am programmatically controlling Bluetooth pairing and unpairing. I can pair before connection and unpair afterwards. The reason I need to do this is specific to my application and not in the scope of my question.

基本上我正在做的是:

1. 获取对 IBluetooth 对象的引用 ib，如这个答案
2. 为 android.bluetooth.device.action.PAIRING_REQUEST 注册一个广播接收器
3. 调用ib.createBond(address)
4. 等待 BroadcastReceiver 触发
5. 使用 convertPinToBytes()
6. 从 BroadcastReceiver 中调用 ib.setPin(address, pinBytes)

1. Get a reference ib to IBluetooth object as described in this answer
2. Register a BroadcastReceiver for android.bluetooth.device.action.PAIRING_REQUEST
3. Call ib.createBond(address)
4. Wait for BroadcastReceiver to trigger
5. Convert user pin into bytes with convertPinToBytes()
6. Call ib.setPin(address, pinBytes) from within BroadcastReceiver

无论如何，这种方法非常有效，除了当我进行配对时，我会在状态栏中收到一条通知，要求用户输入 PIN 以完成配对.但这实际上是不必要的，因为当用户看到这个时，我的应用程序已经使用了 setPin().我真的希望该通知 a) 根本不出现，或者 b) 以某种方式自动关闭.

Anyways, this approach works great, except for the fact that when I do the pairing, I get a notification in the Status bar requesting that the user enter a PIN to complete the pairing. But this is in fact unnecessary, because by the time the user sees this, my app has already used setPin(). I'd really like for that notification to either a) not appear at all, or b) be dismissed automatically somehow.

我意识到这甚至可能是不可能的，但我想如果有人有创意我会问.

I realize this may not even be possible, but I thought I would ask in case someone has a creative idea.

推荐答案

尝试在PAIRING_REQUEST

BluetoothDevice device = intent.getParcelableExtra("android.bluetooth.device.extra.DEVICE");

device.getClass().getMethod("setPairingConfirmation", boolean.class).invoke(device, true);
device.getClass().getMethod("cancelPairingUserInput").invoke(device);

这对我在使用 RFCOMM 的两台 Android 设备之间有效，但我没有输入任何 PIN 码

This worked for me between two Android devices using RFCOMM but I'm not entering any PINs
