2.2 SDK Directory Structure

2.3 Quick Integration

Before you use the SDK, you need to integrate it into your development environment first.

1,Import DFOCRScanDemo's DFOCRScan module to your project by File->New->importModule->Select the DFOCRScan in DFOCRScanDemo folder->Continuously click Next to complete the import.

2,Add following code to the dependencies{} section of build.gradle.

compile project(':DFOCRScan')

For example:

allprojects {
    repositories {
        google()
        jcenter()

        flatDir {
            dirs project(':DFOCRScan').file('libs')
        }

    }
}

 dependencies {
     compile project('DFOCRScan')
 }

3,Copy all files in the assets directory of the DFOCRScanDemo project to your project's assets directory.

2.4 Start Detection

Jump detection card activity

 DFOCRScan.create(this)
        .startCardDetect()
        .forResult(100);

Use onActivityResult to receive data

if (requestCode == 100){
    if (resultCode == RESULT_OK) {
            //detect card result
            DFCardInfo cardInfo = DFOCRScan.obtainCardResult(data);

            String cardType = cardInfo.getCardType();
            if (TextUtils.equals(cardType, DFCardInfo.CARD_TYPE_AADHAAR_CARD_FRONT)) {
                DFAadhaarCardFrontInfo  aadhaarCardFrontInfo = (DFAadhaarCardFrontInfo) cardInfo.getCardInfo();
            } else if (TextUtils.equals(cardType, DFCardInfo.CARD_TYPE_AADHAAR_CARD_BACK)) {
                DFAadhaarCardBackInfo  aadhaarCardBackInfo = (DFAadhaarCardBackInfo) cardInfo.getCardInfo();
            } else if (TextUtils.equals(cardType, DFCardInfo.CARD_TYPE_PAN_CARD)) {
                DFPanCardInfo  panCardInfo = (DFPanCardInfo) cardInfo.getCardInfo();
            }
    } else {
        if (data != null) {
              //error code
              int errorCode = DFOCRScan.obtainErrorCode(data);
        }
    }
}

card result refer to DFCardInfo

aadhaar front card result refer to DFAadhaarCardFrontInfo

aadhaar back card result refer to DFAadhaarCardBackInfo

pan card result refer to DFPanCardInfo

2.5 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.** { *; }

2.6 Get SDK Version

int sdkVersion = DFOCRClassifySDK.getSDKVersion()
