如何通过程序重命名Android蓝牙配对设备？

Question

I need to "rename" bluetooth paired device of Android phone with programming. But searching results are most discuss about local bluetooth rename method. And it could use setname() to complete. Does there have any method to rename "paired device" of Android phone ?

Answer 1

I know the question is old, but I just needed this and found out how to do it. It uses reflexion so I'm not sure this is the best way to go but it works.

public void renamePairDevice(BluetoothDevice device, String name) 
        throws IllegalAccessException, InvocationTargetException, NoSuchMethodException
{
    Method m = device.getClass().getMethod("setAlias", String.class);
    m.invoke(device, name);
}

I don't think you can rename the name of the paired device. You can only change the name from the paired device's settings.

Think of it like a wifi router, you cannot change the name of the router, but you can only connect to it.

However if you want,you could assign this way

Set<BluetoothDevice> devices = btAdapter.getBondedDevices();
    if (devices.size() > 0) {
         for(int i=0;i<device.size();i++) {
            mDevice[i] = device;
            bondedDevices.add(mDevice.getName());


        }
    }

That way you could get the name of the paired Devices as a mDevice array. Hope it solved your issue
