Unity使用單元格.jar Android NFC

Question

AndroidJavaException：java.lang.SecurityException：需要NFC權限：用戶10379或當前進程都沒有android.permission.NFC。

我的AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?> 
    <manifest xmlns:android="http://schemas.android.com/apk/res/android" android:installLocation="preferExternal" package="com.Company.PluginsNFC" android:versionName="1.0" android:versionCode="1">

     </activity> 


     </application> 
     <uses-sdk android:minSdkVersion="9" android:targetSdkVersion="19" /> 
</manifest> 

我找了很久也找不到那裏的問題是

代碼：

public boolean IsUseNFC() { 

     this.mNfcAdapter = NfcAdapter.getDefaultAdapter(this.activity); 

     if(this.mNfcAdapter == null) { 
      this.activity.finish(); 
      return false; 
     } 

     if(!this.mNfcAdapter.isEnabled()) { 
      this.activity.finish(); 
      return false; 
     } 

    this.mNfcAdapter.setNdefPushMessageCallback(this, this.activity); 

    return true; 
} 

[錯誤] NfcAdapter.setNdefPushMessageCallback （this，this）;

Answer 1

如錯誤消息所示，您沒有爲您的應用程序請求NFC權限。您需要添加

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

在應用程序mainfest中的<application ... />標記之前的某處。
