在Android中，有没有合适的方法来检测用户在应用运行或关闭状态下是否添加或删除了指纹？

<uses-permission android:name="android.permission.USE_FINGERPRINT" />

FingerprintManager fingerprintManager = (FingerprintManager) getSystemService(Context.FINGERPRINT_SERVICE);
if (!fingerprintManager.isHardwareDetected()) {
    // 设备不支持指纹识别
}

if (!fingerprintManager.hasEnrolledFingerprints()) {
    // 用户未添加指纹
}

FingerprintManager.AuthenticationCallback authenticationCallback = new FingerprintManager.AuthenticationCallback() {
    @Override
    public void onAuthenticationError(int errorCode, CharSequence errString) {
        // 指纹识别错误
    }

    @Override
    public void onAuthenticationHelp(int helpCode, CharSequence helpString) {
        // 指纹识别帮助信息
    }

    @Override
    public void onAuthenticationSucceeded(FingerprintManager.AuthenticationResult result) {
        // 指纹识别成功
    }

    @Override
    public void onAuthenticationFailed() {
        // 指纹识别失败
    }
};

fingerprintManager.authenticate(null, null, 0, authenticationCallback, null);
