How to Customize Your Android App

This guide explains how to manually change the key properties of your application.

1. App Name

To change the display name of your app (what users see under the icon):

  1. Open app/src/main/res/values/strings.xml.
  2. Find the line: <string name="app_name">My HTML App</string>.
  3. Change "My HTML App" to your desired name.

2. App Icon

To change the app icon:

  1. Place your new image file (e.g., my_icon.png) in the app/src/main/res/drawable folder.
  2. Open app/src/main/AndroidManifest.xml.
  3. Find the <application> tag.
  4. Update the android:icon and android:roundIcon attributes to match your file name: 
    android:icon="@drawable/my_icon"
android:roundIcon="@drawable/my_icon"

3. Package Name (Application ID)

This connects your app to the Play Store and identifies it uniquely.

  1. Open app/build.gradle.
  2. Find the defaultConfig block.
  3. Change the applicationId value: 
    applicationId "com.yourcompany.appname"

4. App Version

To update the version when releasing updates:

  1. Open app/build.gradle.
  2. Inside defaultConfig:
    • versionCode: Integer that must increase with every release (e.g., 1, 2, 3...).
    • versionName: String visible to users (e.g., "1.0", "1.1", "2.0").
    versionCode 2
versionName "1.1"

5. Apply Changes

After making any of these changes, sync your project with Gradle (if using Android Studio) or rebuild the app for the changes to take effect.

6. How to Compile & Run

Once you are happy with your changes, here is how to build the app:

Using Android Studio (Recommended)

  1. Open Android Studio and select Open.
  2. Navigate to and select the AndroidHtmlApp folder.
  3. Wait for Gradle sync to complete.
  4. Connect your Android device or create an Emulator.
  5. Click the green Run button (▶) in the toolbar.
  6. To build an APK for sharing: Go to Build > Build Bundle(s) / APK(s) > Build APK(s). The APK will be in app/build/outputs/apk/debug/.

Using Command Line

If you have the Android SDK installed:

  1. Open a terminal in the AndroidHtmlApp folder.
  2. Run the build command:
    • Windows: gradlew.bat assembleDebug
    • Mac/Linux: ./gradlew assembleDebug
  3. Find the APK at app/build/outputs/apk/debug/app-debug.apk.
