FAQ

📘 My app only needs to support one language, and the default language is not English. What should I do?

• Add the following configuration in the build.gradle file of your app module to ensure that other languages are ignored when packaging the APK.

android {  
       defaultConfig {
         ...
         resConfigs("in-rID") // For example, only Indonesian is supported
       }
   }

• Since the default language of the SDK is English, meaning the values directory contains English resources, you need to copy the language resources from the values-in-rID folder to the values directory to replace the English resources.

📘 My app has undergone code obfuscation using ProGuard. Do I need to add additional obfuscation rules for the IQA SDK?

No, it’s not necessary. The SDK has built-in consumer roles.

📘 What value should be passed as the userId in the bindUser method?

A string that can identify the current liveness event. Recommended values: user ID, username, device ID, transaction number.

📘 How much memory will the SDK consume at runtime?

It depends on the camera performance, there is no specific value. It is recommended to use relevant tools for detection.

📘 Scanning found that the SDK called methods like androidId that access device information, how to remove it?

Use the corresponding nd version of the core dependency:（Here, we take version 6.0.0 of the core as an example. In fact, each version of the core has a corresponding ND version, and you should choose the core that matches the current IQA SDK version.）

📘 Do I need to save the eventId? What is the purpose of eventId?

Yes, the eventId is very important. It is a key field used for reporting issues to us. Without this ID, it will be difficult to troubleshoot problems, so please make sure to save it.
