1: Open (app/src/main/res/values/strings.xml)
Find the line: <string name="app_name">My HTML App</string>
Change "My HTML App" to your desired name.
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
Update the android:icon and android:roundIcon attributes to match your file name:
android:icon="@drawable/my_icon"
android:roundIcon="@drawable/my_icon"
This connects your app to the Play Store and identifies it uniquely.
Open app/build.gradle
Find the defaultConfig block.
Change the applicationId value:
applicationId "com.yourcompany.appname"
To update the version when releasing updates:
Open app/build.gradle.
app/build.gradle.defaultConfig:
versionCode 2
versionName "1.1"
Just like modifying html content you need to sync with gradle, you do the same when changing any of these values
Celebrate!
