How do I share a PDF on Android?

Quick start (minimal MWE)

import com.mobilebytelabs.kmptoolkit.share.Share
import com.mobilebytelabs.kmptoolkit.share.SharePayload
import com.mobilebytelabs.kmptoolkit.share.ShareOptions
import java.io.File

suspend fun shareInvoice(pdfFile: File) {
    Share.share(
        payload = SharePayload.File(
            path = pdfFile.absolutePath,
            mimeType = "application/pdf",
            displayName = pdfFile.name,
        ),
        options = ShareOptions(title = "Share invoice"),
    )
}

Caveats / per-platform notes

• Android: the file must be reachable via FileProvider. cmp-share auto-wires the manifest <provider> entry; if you've overridden it, ensure your authority matches ${applicationId}.cmp-share.fileprovider.
• iOS: mime type ignored — UTI inferred from the file extension; use .pdf.
• JS / wasmJs: falls back to download-then-share via Web Share API Level 2; Safari only supports it inside a user-gesture handler.
• JVM Desktop: opens the system "Share" dialog on macOS Sonoma+ / Windows 11; otherwise opens the Files browser at the parent directory.
