Usage:

Adding the depencency

Add this to your root build.gradle file:

allprojects {
    repositories {
        ...
        maven { url 'https://jitpack.io' }
    }
}

Now add the dependency to your app build.gradle file:

compile 'com.github.marcoscgdev:FingerAuth:1.0.0'

Creating a dialog

Here is a complete snippet of it usage:

new FingerAuthDialog(this)
        .setTitle("Sign in")
        .setCancelable(false)
        .setMaxFailedCount(3) // Number of attemps, default 3
        .setPositiveButton("Use password", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialogInterface, int i) {
                // do something
            }
        })
        .setOnFingerAuthListener(new FingerAuth.OnFingerAuthListener() {
            @Override
            public void onSuccess() {
                Toast.makeText(MainActivity.this, "onSuccess", Toast.LENGTH_SHORT).show();
            }
            
            @Override
            public void onFailure() {
                Toast.makeText(MainActivity.this, "onFailure", Toast.LENGTH_SHORT).show();
            }

            @Override
            public void onError() {
                Toast.makeText(MainActivity.this, "onError", Toast.LENGTH_SHORT).show();
            }
        })
        .show();

Show dialog only on devices that support fingerprint auth:

boolean hasFingerprintSupport = FingerAuth.hasFingerprintSupport(this);

if (hasFingerprintSupport)
    fingerAuthDialog.show();

Implementing your own method

new FingerAuth(this)
        .setMaxFailedCount(3) // Number of attemps, default 3
        .setOnFingerAuthListener(new FingerAuth.OnFingerAuthListener() {
            @Override
            public void onSuccess() {
                // do something
            }

            @Override
            public void onFailure() {
                // do something
            }

            @Override
            public void onError() {
                // do something
            }
        });

Override strings

<string name="fingerauth_dialog_description">Confirm fingerprint to continue</string>
<string name="fingerauth_dialog_hint">Touch sensor</string>
<string name="fingerauth_dialog_not_recognized">Fingerprint not recognized. Try again</string>
<string name="fingerauth_dialog_success">Fingerprint recognized</string>
