Android SDK

SDK module introduction

The Financial-grade Real Person Authentication Android SDK includes the following modules:

Module name	Description	Compiled size
Module name	Description	Dual architecture	ARM64	ARMv7
aliyun-base-[version]-[timestamp].aar	Basic feature module.	2.65 MB	1.90 MB	1.69 MB
aliyun-facade-[version]-[timestamp].aar	Basic feature module.
aliyun-face-[version]-[timestamp].aar	Basic feature module.
aliyun-facequality-[version]-[timestamp].aar	Strict Face Quality Detection module. This module is not included in the default package because it increases the SDK package size. To use this module, download the complete SDK from the link. Note When this module is enabled, the client prompts the user to retry detection if the face is occluded, for example, by a hat or a mask. This helps capture a higher-quality face image before authentication. The strict quality detection may decrease the face recognition success rate. For the ID_PRO solution, set the `AppQualityCheck` parameter to `Y` when you call the InitFaceVerify-Initiate authentication request operation.	5.04 MB	3.68 MB	3.22 MB
aliyun-photinus-[version]-[timestamp].aar Note Starting with SDK 2.3.38, this module is merged into the aliyun-face module.	Colorful liveness detection module.	8.49 KB
aliyun-faceaudio-[version]-[timestamp].aar	Senior-friendly mode audio resources.	65.10 KB
aliyun-facelanguage-[version]-[timestamp].aar	Multi-language resources. Note Multi-language support applies only to text prompts on the face recognition page. Other pages are not supported.	18.0 KB
aliyun-ocr-[version]-[timestamp].aar	ID card OCR module.	211.92 KB
aliyun-nfc-[version]-[timestamp].aar	NFC authentication module.	2.84 MB	2.54 MB	2.05 MB
aliyun-wishverify-[version]-[timestamp].aar	Multi-factor intent authentication module.	427.05 KB
Android-AliyunFaceGuard-[version].aar	Device assistant module.	2.22 MB	1.28 MB	0.94 MB
APSecuritySDK-DeepSec-[version].[timestamp].jiagu.aar	Secures the authentication channel.	4.13 MB	2.24 MB	1.99 MB
aliyun-facebeauty-[version]-[timestamp].aar	Beauty filter module.	9.29 KB

Note

version is the SDK version, and timestamp is the timestamp when the SDK was generated. Refer to the downloaded SDK for actual values.
The package size may vary depending on the compilation environment. Refer to the actual compilation result.

Module trimming instructions

By default, the SDK downloaded from the development reference is a full-featured module that includes all product capabilities certified on the official website. During actual use, you can adjust the dependencies in build.gradle based on the following instructions and your actual business scenarios:

# Alibaba Cloud Real Person Authentication Service SDK AARs

Compile-time trimming

To further reduce the SDK package size, you can modify the build script to remove the toyger.face.dat and toyger.quality.dat face model files. These files are in the Assets directories of the aliyun-face and aliyun-facequality modules, respectively. You can then download them on-demand at runtime to ensure authentication works properly.

android {
    ...
        android.applicationVariants.all { variant ->
            variant.mergeAssets.doLast {
                delete(fileTree(dir: variant.mergeAssets.outputDir, includes: ['toyger.face.dat', 'toyger.quality.dat']))
            }
        }
}
