Android App Dev Example

android app development example

Here’s a simple example of an Android app development:

Open Android Studio

Enter the name and package name for the app, then click “Finish”
In the MainActivity.java file, add the following code to display a “Hello World” message:
java
Copy code
import android. os.Bundle;
import android. widget.TextView;

import android.appcompat.app.AppCompatActivity;

public class MainActivity extends AppCompatActivity {

@Override
protected void onCreate(Bundle saved instance state) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

TextView textView = findViewById(R.id.text_view);
textView.setText(“Hello World”);
}
}
In the activity_main.xml file, add the following code to create a TextView to display the message:
Python
Copy code
<TextView
android:id=”@+id/text_view”
android:layout_width=”wrap_content”
android:layout_height=”wrap_content”
android:textSize=”30sp”
android:text=”Hello World” />
Run the app on an emulator or physical device by clicking the “Run” button in Android Studio.
This is just a simple example to demonstrate the basics of Android app development. You can build upon this to create more complex apps with various features and functionalities.

 Here are a few more steps to add functionality to the app:

Add a button to the activity_main.xml file:
Python
Copy code
<Button
android:id=”@+id/button”
android:layout_width=”wrap_content”
android:layout_height=”wrap_content”
android:text=”Click Me” />
In the MainActivity.java file, add an OnClickListener for the button to change the text of the TextView:
java
Copy code
import android. view.View;
import android. widget.Button;

…

public class MainActivity extends AppCompatActivity {

…

@Override
protected void onCreate(Bundle saved instance state) {
…

Button = findViewById(R.id.button);
button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
textView.setText(“Button was clicked”);
}
});
}
}
Run the app again and test the button by clicking it. You should see the text of the TextView change to “Button was clicked.”
This is just a basic example of adding button functionality to an Android app. You can use these concepts to create more complex apps with various buttons and actions.

Android App Language: Java.

android app code language

The primary language used for developing Android apps is Java, however, other programming languages such as Kotlin, C++, and Python can also be used.

Additionally, Android Studio, the official Integrated Development Environment (IDE) for Android app development, provides support for both Java and Kotlin programming languages.

 Java is the most commonly used language for Android app development due to its rich collection of libraries and its long history of usage for building applications on the Java platform.

Kotlin, on the other hand, is a more modern and concise language that is fully interoperable with Java and has gained popularity as an alternative language for Android development. C++ can also be used for developing native Android apps, but this is more commonly used for performance-critical components such as games.

Python is a high-level programming language that can be used to build Android apps through a variety of tools and frameworks. Ultimately, the choice of language for Android app development will depend on the requirements of the app and the developer’s experience and preference.

No programming language is prohibited from being used for Android app development. However, some programming languages, such as Ruby and Swift, are not as commonly used for developing Android apps compared to Java, Kotlin, C++, or Python.
That being said, it is possible to build Android apps with these languages through the use of cross-platform development tools or by using a different approach such as using a WebView to run a web app inside a native app container.

Ultimately, the choice of language for Android app development will depend on the requirements of the app and the developer’s experience and preference.

It’s worth mentioning that while any programming language can technically be used to develop Android apps, some are better suited than others.

Java and Kotlin are officially supported by Google and have a large community of developers, making them the most popular choice for Android app development.

C++ can also be used to develop high-performance components of Android apps, such as games, and is well-suited for this use case due to its low-level nature and performance optimizations.

Python, while not as commonly used as Java or Kotlin, can still be a viable option for building simple Android apps, especially for those familiar with the language.

In contrast, languages like Ruby and Swift were not originally designed for mobile app development, and as such, may require additional effort and tooling to get up and running for Android development.

Furthermore, the support and community for these languages in the Android ecosystem may be limited, making it more difficult to find help or resources when needed.

Ultimately, the choice of programming language for Android app development will depend on various factors, including the complexity of the app, the experience and skills of the developer, and the available tools and libraries for the language in question.
