AttributedHandler.java

package com.gmail.altakey.bette.hack;

import android.os.Handler;
import android.os.Looper;
import android.os.Message;

public class AttributedHandler extends Handler {
    public AttributedHandler() {
    }

    public AttributedHandler(Callback callback) {
        super(callback);
    }

    public AttributedHandler(Looper looper) {
        super(looper);
    }

    public AttributedHandler(Looper looper, Callback callback) {
        super(looper, callback);
    }

    public boolean postDelayed(Runnable r, Object token, long delayMillis) {
        return sendMessageDelayed(getPostMessage(r, token), delayMillis);
    }

    private Message getPostMessage(final Runnable r, final Object token) {
        final Message m = Message.obtain(this, r);
        m.obj = token;
        return m;
    }
}

postDelayed is final since Android 28
