1. Gradle

compile 'com.wei.android.lib:fingerprintidentify:1.2.1'

2. AndroidManifest

<uses-permission android:name="android.permission.USE_FINGERPRINT"/>
<uses-permission android:name="com.fingerprints.service.ACCESS_FINGERPRINT_MANAGER"/>
<uses-permission android:name="com.samsung.android.providers.context.permission.WRITE_USE_APP_FEATURE_SURVEY"/>

3. FingerprintIdentify api

mFingerprintIdentify = new FingerprintIdentify(this);                       // create object
mFingerprintIdentify = new FingerprintIdentify(this, exceptionListener);    // exception callback for develop only
mFingerprintIdentify.isFingerprintEnable();                                 // is fingerprint usable
mFingerprintIdentify.isHardwareEnable();                                    // is hardware usable
mFingerprintIdentify.isRegisteredFingerprint();                             // is fingerprint collected
mFingerprintIdentify.startIdentify(maxTimes, listener);                     // start identify
mFingerprintIdentify.cancelIdentify();                                      // cancel identify
mFingerprintIdentify.resumeIdentify();                                      // resume identify

4. startIdentify method

mFingerprintIdentify.startIdentify(3, new BaseFingerprint.FingerprintIdentifyListener() {
    @Override
    public void onSucceed() {
        // succeed, release hardware automatically
    }

    @Override
    public void onNotMatch(int availableTimes) {
        // not match, try again automatically
    }

    @Override
    public void onFailed(boolean isDeviceLocked) {
        // failed, release hardware automatically
        // isDeviceLocked: is device locked temporarily
    }

    @Override
    public void onStartFailedByDeviceLocked() {
        // the first start failed because the device was locked temporarily
    }
});

5. Proguard

# MeiZuFingerprint
-keep class com.fingerprints.service.** { *; }

# SmsungFingerprint
-keep class com.samsung.android.sdk.** { *; }

6. Notice

1. Usually, device will be locked temporarily when read incorrect fingerprints continuously 5 times.
   And it need to takes about 30 seconds to get back to normal.
   But it's not standardized, MeiZu SDK has no limit to this.

2. About 'com.android.support:appcompat-v7:25.3.1' version
   The class FingerprintManagerCompatApi23 will check the feature FEATURE_FINGERPRINT from version 25.
   More info：https://code.google.com/p/android/issues/detail?id=231939

3. Some manufacturers will transplant standard fingerprint API to the device
   which version less than Android M, such as OPPO.
   But the API will be modified sometimes and cause calling crash, such as VIVO.

4. We need to check the manufacturers because Meizu's sdk is available on some other devices.

5. MeiZu's SDK runs abnormally on MeiLan Note3 sometimes, it can't switch to mback mode event called release。
