Build Android App Step By Step


Change The Background Color Of The Layout

01. How to Make an Awesome Android App Step by step (MAC SETUP)

Give your new activity a different background color than the first activity:

  • In colors.xml, add a new color resource:
  • < color name="screenBackground2"> #26C6DA< /color> 
  • In the layout for the second activity, fragment_second.xml, set the background of the ConstraintLayout to the new color.
  • In the Attributes panel:

    Or in XML:

    Your app now has a completed layout for the second fragment. But if you run your app and press the Random button, it may crash. The click handler that Android Studio set up for that button needs some changes. In the next task, you will explore and fix this error.

    Publish Your App On The Stores

    Publish your apps on the stores: Google Play and App Store

    Once your app is ready, it is time to think about publishing it. Its a good idea to publish your app on as many platforms as possible as it will allow you to reach as many users as possible.

    Publishing an app can be a complex and slightly overwhelming process, starting with registering as a developer

    Developers’ accounts . For Apple devices you will be subscribing to the Developer Program for the App Store , costing $99 per membership year. Keep in mind that Apple requires the owner of the content in the app to match the owner of the developer account, so if you publish multiple iOS apps for different projects, each will need to have its own individual developer account. Becoming a Publisher costs $25 , and you must also own a Gmail account.

  • Google Play: Android offers different choices to distribute apps, however with over 1 billion active users, Google remains the premier platform for Android apps.
  • Store listing and mandatory info

    Dont launch all features at once, its good to hold back. It gives you room to further develop your application and launch an updated version later on.

    With the GoodBarber Takes Care service, you let our experts do all the work for you. They will take care of the publication process of your app on Google Play and the App Store, so you can focus your Marketing Strategy.

    Add A Constraint To The New Button

    You will now constrain the top of the button to the bottom of the TextView.

  • Move the cursor over the circle at the top of the Button.
  • The Button moves up to sit just below the TextView because the top of the button is now constrained to the bottom of the TextView.

  • Take a look at the Constraint Widget in the Layout pane of the Attributes panel. It shows some constraints for the Button, including Top -> BottomOf textView.
  • Take a look at the XML code for the button. It now includes the attribute that constrains the top of the button to the bottom of the TextView.
  • You may see a warning, “Not Horizontally Constrained“. To fix this, add a constraint from the left side of the button to the left side of the screen.
  • Also add a constraint to constrain the bottom of the button to the bottom of the screen.
  • Before adding another button, relabel this button so things are a little clearer about which button is which.

  • Look at the Attributes panel on the right, and notice the id field.
  • Change the id from button to toast_button.
  • Three: Create A Prototype

    how to create free android app without coding in simpal way step by ...

    Once youve figured out how you would like the application to look, and youve got a clear idea of its functionality, the next step is to create a working prototype.

    “This could be a simple paper prototype outlining your ideas,” explains Gumtree’s Android app team lead, Claudia Hosu. “Or a digital one with a mock-up of your proposed app.”

    Feedback is perhaps the most important tool for successfully completing this stage. Your initial ideas may have seemed solid as a concept and may have even looked doable on paper, but not every idea will work well with users in the real world.

    This stage isnt simply about making your paper plan a reality. You should spend a great deal of time tweaking the features, design, and UX of your app, as well as address any unexpected conflicts or broken functions. If you dont find any issues, its very likely youve missed something.

    The most valuable feedback will come from a random group of neutral testers, who will be able to provide honest reactions to your work just be warned that everyone will be a fan.

    How Do You Make Money With An App

    There are lots of different ways to make money with an app.

    For starters, you can use a mobile app to generate more revenue for your business. Mobile commerce sales, customer loyalty programs, and referral programs are all excellent ways to make money.

    You can also make money by charging app users a one-time fee to download your app. App purchases for things like coins or content upgrades are both common ways to profit from your app. Alternatively, charging app users for a subscription on a monthly or annual basis is a great way to generate recurring revenue.

    Another way to monetize your app is by selling advertising space. Its the same concept of running ads on your website.

    In some cases, certain types of apps dont necessarily make money, but they help save you money. Internal business apps are a perfect example of this. Creating an app for remote employees, field service workers, human resources, or internal employee communication can save your company tens of thousands of dollars per year in productivity costs.

    Give Your Mobile App Regular Aso Health Checks

    If your app downloads have flatlined, dont panic.

    Maybe your app has been sitting in the Apple App Store or Google Play Store for a while, and growth is stagnating. What can you do about it?

    A mobile app, much like the human body, needs regular fixing and fine-tuning. Theres always room for improvement in fact, you should be actively looking for ways to improve your app: updating it with the latest software, adding new features, fixing bugs, etc. And you should always be exploring strategies to expand your user base.

    That bring us to the ASO health check.

    1. Reconfirm Your Keywords

    Understanding how your target audience conducts a search is the first step toward making your app visible in the app store.

    Even if you did some keyword research when you first launched the app, its likely your users needs have evolved and theyre searching for terms that you havent leveraged yet.

    Keep in mind: The words you associate with your app may not be the same ones your target audience is actually searching for. You have to do your research to make sure that the problems your audience is trying to solve and the features theyre looking for are incorporated into your keywords.

    Having the right keywords and placing them correctlyin the title, subtitle, description and/or keyword bank is crucial to getting more eyes on your app.

    2. Update Your App Icon

    Have you considered that your branding may be in need of a refresh?

    3. Upload New Screenshots

    Adding A Menu To Your App

    Now that you configured the Auth0 library, the next thing you will do is to add a menu for your app. This will be a dynamic menu that will allow users to either log in or log out .

    To start defining this menu, create a new directory called menu inside ./app/src/main/res/. Then, create a file called menu.xml inside menu and add the following code to it:

    This menu is quite simple. It contains a single item just with an id and an empty title. You will define the title of the menu, along with its behavior, programmatically.

    Now, as the menu will only cover two scenarios , you will define two menu listeners: LoginListener and LogoutListener. When your users click on the menu, your app will call one of these listeners to either start the authentication process or end the user session.

    To define the first listener, create a class called LoginListener inside the com.auth0.todo.util package and add the following code to it:

    As you can see, this class implements an interface called MenuItem.OnMenuItemClickListener. It also defines a constructor that receives an instance of a class called AuthenticationHandler. You will create this class soon. Lastly, it defines that the onMenuItemClick will trigger a method called startAuthenticationProcess. As its name suggests, this method will start the authentication process.

    After defining the login listener, you will create the LogoutListener inside the same package and add the following code to it:

    In the previous phase, you should have a very good concept of what your app will look like and what features you want to include. So now is the ideal time to start sketching out your app and creating a storyboard to give your concept some form. However, in order to boost your app’s competitiveness, your storyboard must be strategic.

    Examine your competitors’ performance and the Google App Store’s evaluations to see where you’ll need to fill those gaps. Their flaws will serve as the ideal USP for your Android app. As a result, you may look into their mobile app development history for more information on how to choose the best method.

    See if you can learn more about the difficulties they faced and how they overcome them. Keep a tight eye on everything, pay attention, and take notes.

    How To Plan The Ux & User Journey

    Mapping out the user journey begins on the whiteboard.

    At the stage, youre defining the entire user journey, screen by screen. This doesnt mean crafting beautiful app screensyoure only mapping out the wireframes to understand how the app will function.

    Start with your overall goals for the user. What are you trying to help them do?

    Then map out how they can get from point A to point B as efficiently as possible.

    Once you have the overall journey mapped out, you can refine your wireframes using Sketch. But always make sure youre mapping before investing extra resources into design.

    A seamless UX is often what separates the successful apps from the not-so-successful apps. Here are a few big mistakes you need to avoid when planning your apps UX:

    Mistake #1: Not understanding your users needs

    Understanding your users is the foundation for building any great product, mobile apps included.

    Before you rush into designing your app, you need to understand your audience and be able to answer these questionswhich you might already have some answers to if you did your homework in the previous section:

    • What features and benefits would provide the most value to our user base?
    • What pain points or problems does our product solve?
    • What makes our solution better than the competition?
    • What sort of interface is critical for providing a great mobile user experience?

    Heres a flowchart of the UCD approach:

    Mistake #2: Trying to incorporate too many features

    Heres an example from :

    Run Your App On A Device

    What you need:

    • An Android device such as a phone or tablet.
    • A data cable to connect your Android device to your computer via the USB port.
    • If you are using a Linux or Windows OS, you may need to perform additional steps to run your app on a hardware device. Check the Run Apps on a Hardware Device documentation. On Windows, you may need to install the appropriate USB driver for your device. See OEM USB Drivers.

    How To Find App Developers

    You can find and hire app developers on various websites like Clutch or Upwork. In fact, Space-O also offers a flexible hiring model. You can take interviews before hiring our developers and designers for your dedicated project. We have 99% job success on Upwork and maintain an average rating of 4.8 on Clutch.

    You can check the developers work profile as well as see what their previous clients are saying about them. This helps you in making informed decisions based on it. Further, you should also check out the portfolio of developers to see the kind of work theyve done before. If an app developer or development company has developed a similar app like yours for anyone, this will benefit your project.

    Creating And Configuring An Auth0 Account

    For starters, if you don’t have one yet, you can now . After that, go to the Applications section of your Auth0 dashboard and click on Create Application.

    When you click on this button, Auth0 will show you a dialog where it will ask you for two things:

    • Name: Here, you can type an identifier for your application .
    • Application Type: Here, you will have to choose “Native”.

    After filling in this form, click on the Create button. Doing so will make Auth0 redirect you to the Quick Start section of your new application. From there, head to the Settings section, and search for the Allowed Callback URLs field. In this field, insert the following value:

    • to-do://< YOUR-AUTH0-DOMAIN> /android/com.auth0.todo/callback

    Note: You will have to replace < YOUR-AUTH0-DOMAIN> with the value available on the Domain property of your new Auth0 Application . Also, if you have chosen to use a package name different than com.auth0.todo, you will have to change that too.

    The authentication process at Auth0 happens on a . That is, when your app starts the authentication process, it will open the login page in a browser and, after the authentication takes place, will redirect your user back to your app. This redirection works because your app will register a deep link in the Android device. Then, as you will configure Auth0 to call this deep link, the device will know that it has to open your app again .

    Send The Count To The Second Fragment

    The Next/Random button was set up by Android Studio to go from the first fragment to the second, but it doesn’t send any information. In this step you’ll change it to send a number for the current count. You will get the current count from the text view that displays it, and pass that to the second fragment.

  • Open
  • Find the method onViewCreated and notice the code that sets up the click listener to go from the first fragment to the second.
  • Replace the code in that click listener with a line to find the count text view, textview_first.
  • int currentCount = Integer.parseInt.toString) 
  • Create an action with currentCount as the argument to actionFirstFragmentToSecondFragment.
  • FirstFragmentDirections.ActionFirstFragmentToSecondFragment action = FirstFragmentDirections.actionFirstFragmentToSecondFragment 

    Why Planning Your Ux In Advance Is So Important

    Make Android chat application tutorial step by step 2018 Lecture 1

    Until you plan your user experience , you have no idea how complex your app is going to be and how much time youll need to invest. Youll also have nothing tangible to show people during your user testing sessions.

    Your UX should follow the path of least resistance for the user. The goal is to carry them from point A to their solution as efficiently and intuitively as possible.

    If you dont plan out this journey before building, youll likely end up plotting a complicated path for your usersand then spending time and resources to fix it.

    The later you find issues, the more expensive theyll be to fix. Tomas Hofmann, Software Developer at MindSea
