2.2 Quick Integration

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

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

1. Add the following code to the build.gradle in your application

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

Add following code in the dependencies{} section of build.gradle

compile project(':DFESign')

For example:

allprojects {
    repositories {
        google()
        jcenter()

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

 dependencies {
     compile project('DFESign')
 }

2.3 Start Detection

Jump signature activity

  DFESign eSign = new DFESign();
  eSign.setApiId(API_ID) //required, api id
    .setApiSecret(API_SECRET) //required, api secret
    .setDocumentId("1234678") //required, document id
    .setAadhaarNumber("123456789012") //required, aadhaar number of signatory
    .setName(name) //required, name of signatory
    .setLocation("location") //optional,Address of signatory
    .setReason("reason") //optional,Reason for signing
    .setSignaturePageNumber(1) //optional, the page number which user sign to
    .setXCoordinate(10) //optional, x offset distance of signature area
    .setYCoordinate(10) //optional, y offset distance of signature area
    .setSignatureWidth(200) //optional, width of signature area
    .setSignatureHeight(64) //optional, height of signature area
    .setTickImageFile(BitmapFactory.decodeResource(getResources(), R.mipmap.ic_launcher)) //optional, signature image, if null, a signature image is automatically generated based on the name
    .startESign(this, 100);

Use onActivityResult to get result

protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {
     if (requestCode == REQUEST_START_E_SIGN) {
            if (resultCode == RESULT_OK) {
                //Get the successful signing result
                DFESignResult eSignResult = DFESign.obtainESignResult(data);
                Intent intent = new Intent(this, DFResultActivity.class);
                intent.putExtra(DFResultActivity.KEY_RESULT_DATA, eSignResult);
                startActivity(intent);
            } else {
                //Get the reason why the signature failed
                DFErrorResult errorResult = DFESign.obtainErrorResult(data);
                DFAppUtils.logI(TAG, "dealESignResult", "errorResult", errorResult);
            }
     }
}

DFESignResult for successful result.

DFErrorResult for failure result.
