Android Rename Device's Name For Wifi-direct

I am trying to connect two devices using Wifi Direct, but i want to implement programmatically not by user initiated. And for that i have to change Device's WifiDirect's name like

Solution 1:

this is what worked for me, even though I don't recommend using reflection to access hidden APIs in the WifiP2pManager.

public void setDeviceName(String devName) {
    try {
        Class[] paramTypes = new Class[3];
        paramTypes[0] = Channel.class;
        paramTypes[1] = String.class;
        paramTypes[2] = ActionListener.class;
        Method setDeviceName = manager.getClass().getMethod(
                "setDeviceName", paramTypes);
        setDeviceName.setAccessible(true);

        Object arglist[] = new Object[3];
        arglist[0] = channel;
        arglist[1] = devName;
        arglist[2] = new ActionListener() {

            @Override
            public void onSuccess() {
                LOG.debug("setDeviceName succeeded");
            }

            @Override
            public void onFailure(int reason) {
                LOG.debug("setDeviceName failed");
            }
        };

        setDeviceName.invoke(manager, arglist);

    } catch (NoSuchMethodException e) {
        e.printStackTrace();
    } catch (IllegalAccessException e) {
        e.printStackTrace();
    } catch (IllegalArgumentException e) {
        e.printStackTrace();
    } catch (InvocationTargetException e) {
        e.printStackTrace();
    }

}
