Anroid Platform Fingerprint scheme

Fingerprint scheme of Aegis

In the Java layer, the aegis mainly provides several packages as follows:

Egistec.fingerauth.api.FPAuthListeners;

Egistec.fingerauth.api.FPAuthListeners.EnrollListener;

Egistec.fingerauth.api.FPAuthListeners.EnrollMapProgressListener;

Egistec.fingerauth.api.FPAuthListeners.StatusListener;

Egistec.fingerauth.api.SettingLib;

Specific use,

1) Provide fingerprint-related functions by generating Settinglib objects

MLib = new Settinglib (Context);

2) Set 3 commonly used listener,

Fpauthlisteners.enrolllistener//Fingerprint entry stage get notify, the method will be callback

Fpauthlisteners.statuslistener//When the status of the fingerprint sensor changes, it will be notify

Fpauthlisteners.enrollmapprogresslistener//Fingerprint input (there are 10 stages), each stage input completion will be called once

Specific as follows:

Fpauthlisteners.enrolllistener () {

public void Onfail () {

}

public void OnProgress () {

}

public void Ondoublecheckedfail () {

}

public void onsuccess () {

}

}

Fpauthlisteners.statuslistener () {

public void onbadimage (int status) {

}

public void Onfingerfetch () {

}

public void onfingerimagegetted () {

}

public void onserviceconnected () {

}

public void onservicedisconnected () {

}

public void onstatus (int status) {

}

public void Onuserabort () {

}

}

Fpauthlisteners.enrollmapprogresslistener () {

public void onenrollmapprogress (int progress) {

}

}

3) bind to Settinglib,mlib.bind ();

4) End of service:

Mlib.abort ();

Mlib.disconnectdevice ();

Mlib.cleanlisteners ();

Mlib.unbind ();

5) Typical function call:

A. Enroll Fingerprint: Fingerprint entry

Mlib.setstatuslistener (New Fpauthlisteners.statuslistener () {

public void onserviceconnected () {

Mlib.enroll ("Fp_0" + mfingerindex);

}

});

Lib.bind ();

B. Delete fingerprint: Delete fingerprint template

Lib.setstatuslistener (New Fpauthlisteners.statuslistener () {

public void onserviceconnected () {

Boolean result = Lib.deletefeature (UID);

}

});

Lib.bind ();

C. Remove calibration: Fingerprint calibration

Lib.setstatuslistener (New Fpauthlisteners.statuslistener () {

public void onserviceconnected () {

Lib.connectdevice ();

Lib.removecalibration ();

Lib.disconnectdevice ();

}

});

Lib.bind ();

6. For the preservation of fingerprint data, by the aegis of the completion, we can not see the data collection and preservation process; We only save a row of fingerprint_* as key in Settings.system, and a value of 1 means data_exsit = 1, the data exists.

The name of the fingerprint is similar to: fingerprint_title*
