Send Qr Intent Command Android
An Android app that demonstrates sending custom intents to other apps for dynamic QR code generation, payment processing, and related tasks.
The CommandIntentApp is designed to interact with other Android apps by sending custom intents with specific data. This app can be used for a variety of tasks, including generating and displaying dynamic QR codes, sending payment details, and interacting with third-party apps that handle these commands.
Key Features:
- Toolbar and Edge-to-Edge Support: The app uses an edge-to-edge design to make the UI look modern, along with a custom toolbar for navigation.
- App Selection Spinner: A dropdown spinner allows the user to select the target app for sending intents.
- Send Dynamic Data via Intents: Various buttons enable users to send different commands to the selected target app, including:
1️. Welcome screen command
2️. Payment amount details
3️. QR code generation
4️. Success, failure, and cancellation screens
5. Total amount summary screen
6. Item detail screen
💡 Custom Dialog: A custom dialog is available to input and send payment amounts.
💡 Multiple Colored Buttons: Buttons with different colors are available for various actions, making
the
interface visually distinct.
