Step by Step Android Development Tutorial with Examples

Finding the best Android Development Tutorial is necessary as most of these Android App Tutorials are not for beginners.

Some of these beginners’ tutorials do not give beginners information instead you will find more advanced topics.

Android is an OS (operating system) based on the Linux Kernel. It is developed in the AOSP (Android Open Source Project).

To build your first App, then you should find the tutorial that is suitable for beginners.

If you are a novice in programming or anything related to app program, then it could be very difficult to understand the android app tutorial unless you have some experience in programming.

The step by step Android Development Tutorial with examples offers best practice sections, and it helps the beginners to understand the vital content and helps them build the app on their own just by reading these simple steps.

The AOS (Android Operating System) is divided into four parts, and the application developers of android basically work with the 2-layers on top to develop latest Android applications.

Android software layers:

The Android software layers, these levels are described as Applications, which contains applications like camera, browser, music, and phone.

The other level is Application framework, in which the Android System will have high-level interactions.

Another level is considered as the Libraries and runtime, which contains may standard framework function, including data storage, graphics rendering, and web browsing.

Also, in this level, you can also find the Android runtime and also you will find vital Java libraries for running Android App.

Android Application:

An Android App is a single unit that can be initiated and utilized independently.

This Android application contains configuration files, resource files, and Java Source.

You can categorize the following segments in your configuration files.

Application:   An Android application, this class is commenced before any other component as it is the final component that stopped at the time of application shutdown.  To describe it precisely, Android produced a default application entity for your app.

Activity: An activity is image version of an android application. Each Android app can have various activities. Activities use fragments and views to generate their UI (user interface) and to relate to the user.

Service A service executes jobs without any user interface.  The individuals can communicate with other Android devices and they can send notifications to the user. For instance, a transmit-receiver can inform the user through the notification support in Android

Broadcast receiver: Broadcast receiver or transmit receiver can be listed to listen to system intents and messages.  A receiver gets the report by Android App if any particular event happens. For instance, you can schedule a receiver for the event that the system completed the booting process, or you can schedule for the event that the status of the phone altered, like, somebody is calling.

Content Provider:  It defines a prearrange interface to data application. A source can be used for getting data in one application, but it can also share data with other applications.  Android contains database called SQLite that is constantly used in combination with the content provider. This SQLite Database can store the data that can be accessed easily through the provider.

Configuration through the Manifest File:

The Android Manifest file contains the details of components, metadata, and setting of an Android application.

This file is called as a manifest file, and it converts to the Android System at the time of the application installation.

The Android structure analysis it and decides the capacity of the application.

The file must contain the details of services, activities, and content provider factors of the application.

The Broadcast receiver can either identified here or listed animatedly at runtime.

The Gradle build structure can change the manifest file at manufacture time.

For instance, the app version is usually completed by the Gradle build file.

The following record shows an example for a quick Android manifest file.

<manifest xmlns:android=””



android:versionName=”1.0″ >

<uses-permission android:name=”android.permission.INTERNET” />







android:theme=”@style/AppTheme” >



android:label=”@string/title_activity_main” >


<action android:name=”android.intent.action.MAIN” />


<category android:name=”android.intent.category.LAUNCHER” />





android:label=”Details” >


<activity android:name=”MyPreferenceActivity” >



<service android:name=”RssDownloadService” >






Using the Android device for testing:

use android devise as testing

To use a standard Android Device you should connect the device to the development machine through USB.

On your device activate USB Debugging.

Now, go to Setting and select Development Options, and now press the USB-Debugging option.

You may have to set up the driver on your mobile phone.

Mac and Linux Operating Systems generally work without any driver, but if you are using the MS Windows then you have to install the driver.

If you have connected various devices to your computer, you can choose the one that you want to use.

If only one device is linked, then the app is automatically installed on that device.

Using the Android Virtual Device and Android Emulator:

An Android Emulator can be used run AVD (Android Virtual Device), the emulator can help you use your Android device to play old games.

The AVD facilitates you to experiment your application on particular Android Devices without using the real hardware.

The virtual devices allow you to test the application with certain configurations.

Even if you have the android device with you, you still need to get familiar with the usage and creation of AVDs.

While making your Android Virtual Device, you must classify the configuration for the AVD like the Android API version, the resolution, and the display density.

You can identify various Ads with different compositions and begin them in parallel.

You should remember that if you stop AVD at the startup time, then the AVD might get degraded.

On old device, it takes several minutes, but on a new device, it takes less than a minute to start the new AVD.

The GUI can be controlled with the mouse once you start the AVD.

You can also use the phone buttons through a menu located on the right side of the emulator.

Once you start the AVD, don’t stop during the process.

In case, you want to change the application and try to test a new edition, then just re-use your application on the Android Virtual Device.

An Android Virtual Device made for Android comes with AOSP (Android Open Source Project) programs.

An AVD made for the Google API’s comes with added Google precise code.

The Google API virtual device allows you to test the app using Google Play Services like the NLS (New Location Services) or the New Google API Maps.

While creating the emulator, you can select either Host GPU or Snapshot.

If you choose the Snapshot option, and when you start the device the second time, it starts very quickly this is because when you close the option, the AVD still stores its state.

If you choose Use Host GPU, then the AVD utilizes directly the host computer graphic cards, which makes the interpretation on the emulated device quicker.

Startup Preferences of the Emulator:

If it is possible, you can choose an AVD with image support on the ARM CPU style or support on the Intel CPU structure.

An AVD that uses the Intel system executes the images faster, but sometimes the images supported by Intel do not work on some machines.

If your device does not work on Intel system, then try an ARM system as this system works on all computers.

Android can be developed practically on any sized computer.

But, if you want to experience the best, then develop the app in 2.6 GHz CPU with 8GB of memory.

A Solid State Drive increases the speed of the Android Emulator.

Learn JAVA For Android:

You can develop Android Application in different languages, including C++, C, Java, Scala, etc, but the most popular among them is Java.

It is because Java is the certified language to develop Android App.

That is why it is important for you to learn JAVA before developing the Android App, and you should have good knowledge of OOPS concept.

Design Android UI:

Android UI design templates free

You can design the AUI (Android User Interface) in the application or in XML.

But, most people prefer XML to design Android UI as it gives the clear code and makes it easy to manage, visualize, debug, and edit the App.

Android Programming:

Developing Android Programming can benefit in both ways, one you can have a lot of fun while learning programming, and two, you can earn a lot of money later on.

The reports revealed that Google Play is the biggest mobile App store that has over 1.6 million Apps and every year billions of apps are downloaded.

As you know that the Android Programming can give you the job satisfaction and sound career, and also brings out your hidden talent and makes you the best developer.

Develop Android App In AS (Android Studio):

As an Android App Developer, you will start the journey with learning Java, then you will travel to Android UI programming, and finally, you will reach the last step of developing Android App in AS.

Developing the app in Android Studio is not easy even if you know the theory very well.

That is why you need to follow this kind of step-by-step Android development tutorial so that you can develop it effortlessly.
