Answer 1

As per Jon suggestion, I got another way to enable WifiHotSpot in Android Oreo and above.

public boolean enableTetheringNew(MyTetheringCallback callback) {
    File outputDir = mContext.getCodeCacheDir();
    try {
        proxy = ProxyBuilder.forClass(classOnStartTetheringCallback())
                .dexCache(outputDir).handler(new InvocationHandler() {
                    @Override
                    public Object invoke(Object proxy, Method method, Object[] args) throws Throwable {
                       switch (method.getName()) {
                            case "onTetheringStarted":
                                callback.onTetheringStarted();
                                break;
                            case "onTetheringFailed":
                                callback.onTetheringFailed();
                                break;
                            default:
                                ProxyBuilder.callSuper(proxy, method, args);
                        }
                        return null;
                    }

                }).build();
    } catch (IOException e) {
        e.printStackTrace();
    }
    ConnectivityManager manager = (ConnectivityManager) mContext.getApplicationContext().getSystemService(ConnectivityManager.class);

    Method method = null;
    try {
        method = manager.getClass().getDeclaredMethod("startTethering", int.class, boolean.class, classOnStartTetheringCallback(), Handler.class);
        if (method == null) {
            Log.e(TAG, "startTetheringMethod is null");
        } else {
            method.invoke(manager, TETHERING_WIFI, false, proxy, null);

        }
        return true;
    } catch (NoSuchMethodException e) {
        e.printStackTrace();
    } catch (IllegalAccessException e) {
        e.printStackTrace();
    } catch (InvocationTargetException e) {
        e.printStackTrace();
    }
    return false;
}

private Class classOnStartTetheringCallback() {
    try {
        return Class.forName("android.net.ConnectivityManager$OnStartTetheringCallback");
    } catch (ClassNotFoundException e) {
        e.printStackTrace();
    }
    return null;
}
