Technical content is the core of RuggedLayer. Public resources show reproducible device-interface patterns and the evidence needed to move an existing app toward deployment, while restricted manufacturer SDKs remain behind approved distribution channels.
Comparable device evidence with method, version and limitations.
- An Android app with one workflow that needs a barcode result.
- The exact target model, Android build and approved device SDK identified.
- A decision about wedge, intent or direct SDK transport; do not mix them accidentally.

- 01
Choose the transport for the workflow
Use wedge when a focused form needs a fast retrofit. Use an explicit intent or callback when the application owns the event. Use a direct device API only behind a small adapter so business screens do not depend on vendor types.
- 02
Define the event your application owns
Keep decoded text, raw bytes, symbology and received time together. Treat the transport payload as untrusted input and reject missing, oversized or undecodable data before it reaches inventory logic.
- 03
Open, listen, start and stop in one owner
Register the result path before starting a decode. Start only once, stop when the workflow ends, and close the device resource from every exit path including background, cancellation and errors.
- 04
Prove the unhappy paths
Test an empty payload, duplicate result, timeout, unsupported symbology, screen resume and a device with no scanner option. A green scan on one device is not a compatibility statement for every configuration.

SDK and API patterns
Original adapter pattern. Bind CapturePort to the approved device SDK in your private Android project.
data class CaptureEvent(
val value: String,
val symbology: String?,
val capturedAt: Instant,
)
interface CapturePort {
fun open()
fun start()
fun stop()
fun close()
fun setListener(listener: (CaptureEvent) -> Unit)
}
class ScanWorkflow(private val scanner: CapturePort) {
private var active = false
fun begin(onCapture: (CaptureEvent) -> Unit) {
if (active) return
scanner.open()
scanner.setListener(onCapture)
scanner.start()
active = true
}
fun end() {
if (!active) return
runCatching { scanner.stop() }
runCatching { scanner.close() }
active = false
}

Publication gate
No vendor binary, API reference, firmware or source sample is published until its redistribution permission and supported scope are recorded.
Return an input error and keep the workflow available for another scan.
Deduplicate by a short-lived event key; never silently double-receive inventory.
Stop the current operation, show a recoverable state and allow a controlled retry.
Stop or pause according to the workflow contract, then re-register safely on resume.
How to read the references
Comparable device evidence with method, version and limitations.
- 01
Record model, scanner option, Android build, firmware and SDK release.
- 02
Run cold start, repeated start/stop, background/resume and cancellation tests.
- 03
Use Code 128, a damaged label, an empty trigger and one unsupported symbology.
- 04
Confirm that no raw scan data or customer identifier is written to ordinary logs.
