指纹传感器高于6.0的设备未使用Android指纹SDK

问题描述

我最近在我的应用中实现了指纹认证（当然使用官方的Android指纹SDK！），我的一些用户抱怨他们的手机中装有指纹传感器（使用Android 6.0），但无法使用该功能。 / p>

我对此进行了一些调查，发现三星S5和Note 4设备具有6.0版指纹传感器，但未使用官方的Android指纹SDK。

我的问题：

1. 是否有人拥有使用其设备的设备列表？自己的指纹SDK。
   


2. 在这种情况下，我想向用户传达该应用程序不支持您的设备。有什么可靠的方法可以通过编程方式找到这些设备（ 具有6.0及以上版本不支持指纹传感器的设备）并显示消息？

解决方案

您可以使用FingerprintManager进行检查，如

 如果（Build.VERSION.SDK_INT> = Build.VERSION_CODES.M）{
 FingerprintManager FingerprintManager =（FingerprintManager）context.getSystemService（Context.FINGERPRINT_SERVICE）; 
 if（！fingerprintManager.isHardwareDetected（））{
 //设备不支持指纹API。通知用户。 
} 
} 
  

和往常一样，您需要获得许可

 <使用权限android：name = android.permission.USE_FINGERPRINT /> 
  

I have implemented fingerprint authentication (of course with official Android fingerprint SDK!) in my app recently, some of my users have complained that they have fingerprint sensor (with Android 6.0) in their phone but unable to use the feature.

I have done some investigation on that, and I found that Samsung S5 and Note 4 devices have fingerprint sensor with 6.0 but they are not using the official Android fingerprint SDK.

My questions:

1. Is anyone have the list of devices which uses their own fingerprint SDK.
   
2. In this case, I would like to convey the user that your device is not supported by the app. Is there any reliable way I can programmatically find these devices("Devices with unsupported fingerprint sensor with 6.0 & above") and show the message?

解决方案

You can check it with the FingerprintManager like

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
    FingerprintManager fingerprintManager = (FingerprintManager) context.getSystemService(Context.FINGERPRINT_SERVICE);
    if (!fingerprintManager.isHardwareDetected()) { 
        // Device doesn't support fingerprint api. Notify the user.
    }
}

and as usual, you'll need the permission

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