FAQ

Q1.What else do I need to do if the project turns on the code confusion?

Code confusion will result in crash because of no corresponding methods, therefore, you should add the following code in proguard file:

-dontwarn com.dfsdk.**
-keep class com.dfsdk.** { *; }

Q2.How do I get the SDK version?

int sdkVersion = DFOCRClassifySDK.getSDKVersion()
