Android Tutorial – 100+ Tutorials

Android Studio makes it easier than ever to build, test, and publish your first Android app without getting stuck on the basics. It offers a feature-rich set of tools designed specifically for building apps on the Android platform using the Java programming language. Building an app might seem like an intimidating task, but the truth is that it’s actually easier than you think to make something with just one line of code. Don’t believe us? Take this tutorial and learn how to make an Android app in Android Studio. Android Tutorial – 100+ Tutorials 

Basic Android Application

The basic Android application contains a single activity. An activity is a single, focused thing that the user can do. Activities are subclasses of the Activity class and have their own lifecycle, which includes things like starting up, being destroyed after use and transitions between states (e.g., going from foreground to background).

The first step in creating an Android application is writing this one activity class: Activity1

Fragments

Fragments are a way of structuring an activity. They can be used to create modular activities that have their own UI and behavior, instead of being hard-coded into the main activity.

Fragments are also useful for creating multiple “activities” in a single activity (for example, separate screens). If you’re familiar with MVP (Model-View-Presenter) patterns, then you might be wondering why we would need to use fragments when there’s already a good solution out there? It’s because MVP doesn’t allow us to easily split our functionality across multiple classes or components; instead it relies on ViewModels which have no ability to extend or override any code already written by another class. This means we end up having one huge file with lots of global state which makes it difficult for developers working across different teams – especially if they’re not using RxJava!

Animation and Graphics

  • Create a new project
  • Create a new activity
  • Create a new layout file
  • Set the background color of your layout file (Hint: right-click on it and select Properties > Background)
  • Set the text color of your layout file (Hint: right-click on it and select Properties > Text Color)
  • Set the text size of your layout file (Hint: right-click on it and select Properties > Text Size)

You can also set different styles for each text field, by selecting one in Design Mode, then clicking “Style” under Text Style option at top left corner; this will open up an options window where you can choose from various styles such as bold/italic/underline etc., which must be applied to all fields with same text style Android Tutorial – 100+ Tutorials

Services

Services are a way to run code in the background and have it perform operations when requested. For example, you can use services to update your app’s data in the background while you’re sleeping, or even create a service that only runs every hour or so.

To create a new service:

  • In Xcode, select File > New > Service from the main menu (or right-click on any project in Xcode).
  • Select “Service” from under “Create With”, then click Next. Make sure “Allocate Memory” is checked and click Next again until you reach the screen where you can choose between which type of executable will be created (iOS or MacOS). Choose iOS if this is all about iOS development; otherwise choose MacOS if this is more about macOS development (which requires El Capitan). Click Create!

SQLite

SQLite is a lightweight database that’s embedded in the Android operating system. It’s a relational database, meaning it stores data in tables and has a single record per row.

SQLite is great for simple uses like keeping track of items you want to buy on Amazon or keeping track of friends or family members’ birthdays (or any other type of personal information). You can even use it to save photos from your camera!

The biggest benefit of using SQLite over other databases is that it’s easy to use—and therefore easier for beginners who may not know much about databases or programming languages yet want something easy-to-set up quickly so they can get started learning more advanced topics later on.

Learn about the Android Development

Android is an open source operating system based on the Linux kernel. It’s used to develop mobile devices, desktop computers and smartwatches.

Android is developed by Google and the Open Handset Alliance (OHA). In 2011, Motorola partnered with Google to create the Droid brand of smartphones based on Android’s open source software stack.

How to Make an Android App in Android Studio

Android Studio makes it easier than ever to build, test, and publish your first Android app without getting stuck on the basics. It offers a feature-rich set of tools designed specifically for building apps on the Android platform using the Java programming language. Building an app might seem like an intimidating task, but the truth is that it’s actually easier than you think to make something with just one line of code. Don’t believe us? Take this tutorial and learn how to make an Android app in Android Studio.

Step 1: Creating a Project

Create a new project by clicking the Start a new Android Project button, and set up your desired app name. This will be your package name. Then, go to the next page and fill out the required fields. You can make any changes as you please later on if need be, but this is just for now. Press Finish when you’re done filling out these fields.

Step 2: Designing the User Interface

In the New Project Wizard, name your project (e.g., Hello-World), enter your app’s package name, and set its minimum SDK. Then you can make a new activity by choosing File -> New -> Activity -> Empty Activity and naming it MainActivity.

Step 3: Writing Java Code

We’re going to add another button that we’ll assign a keyboard shortcut to. To do this, go into the Assign Key Stroke menu, find your desired key combination, and type it into the box below. For this example, I’m using CTRL+W as my keyboard shortcut.

Step 4: Testing Your Application

You can now test your application on a real device. Connect your device to your computer and hit the Run button from the top menu bar. If everything is working, you will see a green play icon and the Android Studio welcome screen. Tap the triangle button and select your connected device from the drop-down list. Your app should be available on the default Home screen of that device. Android Tutorial – 100+ Tutorials
