You can also want to put in some SDK equipment. Make positive you download the modern day SDK. Also, set up a system photo if you want to apply the emulator.

Open or Create a Project:

Now, you need a project. If you already have a project, just open it.

To create a new project:

• Click “New Project”.
• Choose a template (like Empty Activity).
• Give your mission a name.
• Set the bundle name and keep location.
• Choose the language (Java or Kotlin).
• Set the minimum SDK (Android five.0 or better is secure).
• Click “Finish”.

Wait for the Gradle build to finish. It may take a few minutes.

Check the Code and Resources:

Before you build the APK, check if your app is working. Make sure:

• There are not any errors.
• The app compiles effectively.
• All photos, layouts, and documents are within the proper folders.

You can also test the app using the emulator or a real phone. Just click the green Play button to run it.

Build the APK File:

Now it’s time to build the APK. Android Studio gives you two main options:

• Debug APK
• Release APK

Debug APK:

This is for testing handiest. It isn’t always signed with a release key. You can set up it on your phone, however you can not post it on the Play Store.

To build a debug APK:

Click “find” to discover the APK document. The file might be in:

ProjectFolder/app/build/outputs/apk/debug/

You will see a file like app-debug.apk.

Release APK:

This is used for publishing. It is signed with a keystore. It is optimized for performance and security.

To build a release APK, follow these steps:

Create a Keystore:

buildTypes {
    release {
        minifyEnabled true
        proguardFiles getDefaultProguardFile(
