Introducing Andromo - Create Android Apps Without Coding

Have you ever tried to learn how to develop an Android app?

If so, you might know that it requires knowledge of programming languages like Java or Kotlin.

Android development is surely a difficult and complex task. But, the Andromo app maker provides you a solution that makes the job a lot easier. It allows you to make an Android app without coding.

It’s a website, meaning that you don’t need to install Android Studio or any other software on your device.

In my opinion, Andromo is a great tool for those who find programming a bit difficult. It enables you to design an app by offering a range of ready-made app features.

For example, you can add the following features with just a click.

Photo Gallery / Wallpaper

Polls
Ads
etc.

And you know what, it’s even easier to customize the design according to your business requirements.

So, no matter whether you are a programmer or not. You can now design, monetize, and publish your app by performing simple steps.

There is a huge number of apps on Google play that are built on Andromo. You can build Games, Recipe apps, Educational apps, Business apps, and many others according to your requirements.

Today, I will explain to you the features and working of Andromo in detail.

So, let’s get started!

Features

Andromo has tons of features (aka Activities) that could help you design any kind of app. But, for the sake of this blog post, I’ll briefly introduce you to a few of them.

Google Maps

Andromo Map activity provides you the facility of displaying your location on the Map. Your user can easily get the navigation and direction of your business.

PDF

By using Andromo PDF activity you can easily insert a PDF file into your Android application. But, remember that this PDF document will open externally.

Youtube Video

You can display Youtube videos inside your Android app by using Youtube activity. Youtube Data API v3 is used in this activity.

Audio

You can create an audio player inside your Android application by using Audio activity.

Photo Gallery

You can upload a photo in your app and display it in the Gallery section by using the Photo Gallery activity. This Activity also allows you to set the size and layout of the photo.

How It Works

In this section, I’m going to explain to you the working model of the Andromo website and how you can make an Android application using it.

At first, you need to create an account on the Andromo.com website. It’s free and no credit card is required. Basically, they offer a completely free trial for two weeks. During this time you have access to all the activities.

I think 14 days are enough to explore this app builder and create a mobile app. After that, if you like this platform then I would highly recommend you to buy a subscription plan.

I myself bought its “PRO” plan that helps me design custom apps for my clients with ease.

Anyways, login to the Andromo.com website and then click on the “CREATE AN APP FOR FREE” button.

You have to pick the theme according to your requirement, and then give a name to your app. After that click on the “BUILD THIS APP” button and you are ready to go.

You will find the following tabs on your screen

When you click on any of these tabs they provide you different functionalities. The most important ones are Activities and Theme.

I will briefly discuss some of these functionalities to help you get familiar with Andromo.

Activities

This tab decides the working of the app. I picked a theme for the Fashion app and the following activities are already included in our app.

We can add or delete activities according to our requirements. There are many other activities available including PDF documents, HTML Archive, Photo Gallery, etc.

You can also change the position of the activity by drag and drop according to your requirements.

When you click on any Activity the following page appears on the website.

There are five tabs inside every activity including Settings, Content, Style, Images, and Toolbar. Now, I will discuss all of them one by one.

Settings

You can insert the Name, Subtitle, and Description of the Activity in this section.

Content

You can place content inside your app according to your activity. Content may include the website’s URL or pictures depending on the activity you’ve selected.

Style

You can change the style of the theme to Global or you can customize it according to your choice.

Images

There is an option of Feature Image and Custom Image and you can also pick Grid Layout or Drawer Icon of your choice.

Toolbar

In the Toolbar, you can customize the design of your app according to your needs.

Theme

In this option, you are allowed to change the theme of your app. When you select the Theme icon, the following page appears.

There are seven tabs under the Theme icon including Startup, Navigation, Settings, Layout, Style, Images, and Toolbar.

Startup

Startup is the first option that controls the initial screen at the launching of your app. You can add any activity in the Dashboard that is selected in the Activity tab.

Navigation

In the Navigation part, you can Enable or Disable the navigation drawer and you also have to decide whether the drawer remains open or close at the start of App.

You can add Title, Subtitle, and Header Images in the Dashboard.

Settings

In the setting tab, you can change your Dashboard name and also show the social sharing buttons.

Layout

You can select the layout of your choice. You have the option of selecting it by appearance or you can design your layout in the form of a Grid, card, or list.

Style

You have to select the Style mode custom or global. In custom, you can change color according to your choice. You can also customize Bodystyle which includes Window Color, Background Color, and Text Color.

Images

In this section, you can upload Background Image and Feature Image. You can even select the layout of your image and change the Drawer icons.

Toolbar

In the toolbar, you have to select custom or global mode. In the custom mode, you can change the color, icon, and Background according to your choice.

Global Style

On the Global style page, you have three tabs Color settings, Image settings, and Toolbar settings. When you click the Global Style menu, the following page appears.

These are the simple options of setting the color, images, and toolbar. Basically, you can customize the look and feel of your app by using these options.

Settings

When you click on the Settings tab following page appears.

Here, you can provide information related to your app like its name, icon, version, etc.

Monetization

Most of us usually want to earn money by creating Android apps. So, this page is going to be the most important one.

When you click on the Monetization tab following page appears.

Through this Monetization tab, you can enable ads in your app and you can use any of the above networks that are shown in the image.

Services

In the services tab, you can add Firebase Analytics, OneSignal, and Intercom. You can view statistics by using Firebase Analytics.

Build

After completing the app you have to build it. This is the last step before you can run it on your Android devices.

Conclusion

In my opinion, Andromo is one of the best app makers for Android. You can create a mobile app for your business even if you don’t have any coding experience.

It is interesting to note that 1.1 million people are actively using Andromo to quickly build their Android apps.

So, what are you waiting for? Try this free android creator now!

How I Hacked Cookie Clicker Game with Inspect Element 2025

Muhammad Furqan Ul Haq — Tue, 02 Feb 2021 17:58:13 +0000

How I Hacked Cookie Clicker Game with Inspect Element

Cookie Clicker is a very popular browser-based game. It revolves around producing cookies for the world. This game gets more interesting over time which keeps the player engaged.

Basically, there are a few ways to get cookies. These cookies can then be used to create new buildings or purchase upgrades. At first, I’m going to mention a few genuine ways to earn cookies.

By clicking the big “Cookie” shown on the user interface.
By creating new buildings. There are different types of buildings and each type can only produce a specified number of cookies per second. Initially, all buildings are locked, but they will get unlocked over time as the game progresses.
By enhancing the efficiency of your cookie store through upgrades.

I would like to mention here that in the past I wrote a very popular article about the best open-source HTML Games. I think the source code of these games will help you improve your game development/hacking skills. So, please do have a look.

Now, here comes the actual hacking stuff you’re waiting for.

Getting Started

As I mentioned earlier, this is a browser-based game. Meaning that it is developed using HTML5, CSS3, and JavaScript. All of these are client-side languages that can be modified through programs like Chrome DevTools.

Let’s open this game in Google Chrome.

Now to open Chrome DevTools, right-click anywhere on the game and select “Inspect” from the context menu. For now, we will only be focusing on its functionality that is written in JavaScript. So, open the “Console” tab.

Another way is to press Ctrl+Shift+J on Windows or ⌘+⌥Option+J on Mac.

You’ve to execute the below-mentioned codes here.

It’s time to hack different features of this Cookie Clicker game.

Hack Cookies

As everything in this game depends on cookies, so I hacked them!

Basically, after analyzing its source code, I found that the functionality of this game is written inside a file called “main.js”.

This file initializes an object Game through which we can easily access different features of Cookie Clicker. For example, we can modify the number of cookies we have using the Game.cookies property.

Let’s do that now!

Simply copy the below code and paste it inside the “Console” tab of Chrome DevTools. Press “Enter” to execute it.

Game.cookies = 57000

Once executed, you will get 57000 cookies absolutely FREE. You can add any number here.

For example, the below code will give you “Infinity Cookies”.

Game.cookies = 999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999

Keep Getting Cookies

This game also has the functionality of earning cookies per second. Game.cookiesPs property will give us a specified number of cookies for one second.

So, why not wrap it inside a setInterval of one second to continuously get more and more cookies?

Here’s the code snippet to do so.

setInterval(function(){
    Game.cookiesPs = 50
}, 1000);

This code will add 50 cookies to your account every second.

Unlock All Upgrades and Purchase Them

Finally, the developers of Cookie Clicker have also provided a cheat to get all upgrades for free.

Basically, the below method will give you all upgrades as well as unlocks all types of buildings. Additionally, you will get 1.000 nonillion cookies.

Game.RuinTheFun();

Now you might be wondering can we hack other browser-based games too?

And the answer is "Yes, definitely!"

You can hack any game no matter whether it is browser-based, Android, or even PC.

I would like to mention that I learned game hacking from guidedhacking.com. It is the best community forum that helps us understand all the concepts of game hacking in a step-by-step manner.

Spend some time there!

You'll find game hacking tutorials and guides right from their main menu. If you find something difficult then you can always ask questions from fellow hackers.

At last, I would say that game hacking is not very difficult. It just depends on how much time you can dedicate to learn it.

Shopify vs WooCommerce - The Best Choice for Dropshipping 2025

Muhammad Furqan Ul Haq — Fri, 06 Nov 2020 08:25:06 +0000

Traditionally, starting an online eCommerce store requires some investment. The major portion of this money is used to purchase the inventory. Meaning that you need to have some products in stock before selling them.

But, dropshipping has completely changed the way we do business online. It introduces the concept of selling someone else products in our store.

To get started, we have two popular options. Whether set up a Shopify store or go with WordPress plugin WooCommerce.

Overview of Shopify and WooCommerce

Shopify is an online service that enables you to launch an eCommerce business with ease. Basically, they manage the technical stuff for you like hosting, security, updates, etc.

Whereas, WooCommerce is a WordPress plugin through which you can create and customize an eCommerce store according to your needs. It gives you much more flexibility than Shopify as you’re in complete control.

How Dropshipping Works?

In dropshipping, you need to source products from online Suppliers and Vendors. Basically, when someone places an order on your website/app then the supplier is automatically informed about it. They receive the order details as well as where to ship them.

Once the order is ready, the supplier ships it to the buyer. Our job is just to bring more customers and the supplier will handle their orders.

Here, we earn money through margins. Meaning that if a supplier is selling a product for $100 and we add that product on our website at $125, then we will earn $25 for each sale.

Dropshipping with Shopify

Shopify is a software to set up an online shop. It has tons of features that make it stand out from other eCommerce platforms.

For example, it has features like:

Readymade themes that are specifically designed for online stores.
Integration with 100 payment gateways.
Launch your shop in 50+ languages.
Out of the box support for Dropshipping.
Quickly integrate with social media platforms. For example, you can sell on Facebook from Shopify.
Intuitive inventory management functionality.
Support for Video & 3D assets.
Subscriptions.
Fast speed web hosting including SSL certificate.
Product reports and analytics.
Support for Augmented reality (AR)

It is a paid service that works on a subscription model. They have three packages to fulfill the needs of small, medium, and large eCommerce businesses.

Basic Shopify – Starting at $29 per month
Shopify – Starting at $79 per month
Advanced Shopify – Starting at $299 per month

Dropshipping with WooCommerce

On the other hand, WooCommerce is an open-source WordPress plugin that allows you to host an online shop yourself.

There are many hosting companies out there, but using the best one is very important for the overall success of the eCommerce business. Here’s a comparison between the best WordPress hosting to help you make an informed decision.

The major reason for using WooCommerce is that Shopify is very costly. They even charge a fee per sale. But, while using WooCommerce we don’t have to give any subscription fee.

As we have the complete source code of WooCommerce so we can easily customize it for any special use case.
