Native Android apps for consumer products and business workflows, tested across the device, connectivity and lifecycle conditions users encounter.

Stock delivery

`SKU-104`

Quantity **1 received**

Saved on device

Synchronization queued

Work resumes after restart

## Tools & technologies

-   Kotlin
-   Jetpack Compose or Views
-   Room
-   Android SDK

## Support the Android devices in your audience.

### Customer applications

Product discovery, account and order journeys for Android users.

### Workforce tools

Role-based records, scanning and task completion on supported handhelds.

### Existing Android apps

Maintain dependencies, modernize screens and fix crash or performance issues.

## Scan stock into a delivery

Capability Example

A worker scans an item and the operating system later closes the app.

### Validate

### Persist

### Resume

Illustrative data. Nothing is sent to an external system.

Example workspace 1 / 3

### Scanned item

-   SKU: 104
-   Expected delivery: D-17
-   Item accepted

Check the scanned identifier against the expected delivery.

### Local delivery

-   Line stored on device
-   Received count updated
-   App closed by operating system

Save the accepted line before updating the visible count.

### Restored session

-   Delivery D-17 reopened
-   Accepted line still present
-   Scan is not counted twice

Restore the delivery from local storage on the next launch.

A recoverable delivery record that can synchronize when connectivity returns.

Follow the record through the next step

## An app that survives real device conditions.

-   **Android source and build setup**
-   **Device coverage report**

-   **Offline and lifecycle tests**
-   **Distribution and support guide**

## Define the device and background-work policy.

### Hardware

Scanner, tablet and phone behavior must be tested on agreed devices.

### Distribution

Public store, enterprise-managed and private distribution have different setup requirements.

## Questions before we start.

### Can an app support low-connectivity environments?

Yes, when local data, synchronization conflicts and retry behavior are designed explicitly.

### Can you work with an existing Java app?

Yes. Maintenance and Kotlin adoption can be staged without rewriting every screen.
