Device support matrix

The SDK probes these vendors by default (SecuGenReader, BioMiniReader, EadakReader), each behind the common FingerprintReader abstraction.

Vendor IDs (device_filter.xml)

List the vendor IDs of the readers you support so Android shows the permission dialog on attach. The vendor-id attribute is decimal — use the values from the table above:

<resources>
    <usb-device vendor-id="4450" />    <!-- SecuGen -->
    <usb-device vendor-id="5841" />    <!-- Suprema BioMini -->
    <!-- EADAK / Aratek (10477, 13962) are permissioned in-code; no filter entry needed -->
</resources>

[!NOTE] The SDK’s VendorCodes registry is the source of truth for which vendor ids are recognised as supported. A device whose id isn’t in that registry is ignored by discovery even if it’s a fingerprint reader.

Connection

  • All readers connect over USB-OTG. Use a quality OTG adapter.
  • Optical sensors (e.g. SecuGen U20) can exceed a phone port’s power budget — use a powered OTG hub if the reader fails to initialise on bus power.
  • Only one reader at a time is expected (USB bus power constraint).

Native ABIs

The AAR bundles native libraries for arm64-v8a and armeabi-v7a. x86_64 (emulator) is not shipped — test on a real device.
