android - Lint error in getting Bluetooth adapter -

-

I'm following the documentation for bluetooth low energy devices to scan BLE devices.

As the doctor, I defined --- 

  Bluetooth adapter mblluetoothAdapter = null; Last BluetoothManager bluetoothManager = (Bluetooth Manager) getSystemService (Event.BULUETOOTH_SERVICE); MBluetoothAdapter = bluetoothManager.getAdapter (); // lint error ..   
 but I am getting a lint error ---  
 
 The API level 18 for the call (current is the minimum 8 ): Android .bluetooth.bluetoothManager #getAdapter   
 So I changed my code -  
  mBluetoothAdapter = BluetoothAdapter.getDefaultAdapter ();   
 What is the code replacement for the above lint error?   
 
 
 You can call  BluetoothAdapter.getDefaultAdapter () . Say that use  
  to create, then call to get it.   
   Alternatively, you can call only the steady assistant.    
 
 Or you can see the build version and start  mBluetoothAdapter , such as  
  If (android.os.build.VERSION.SDK_INT & gt; = android.os.build.VERSION_CODES.JELLY_BEAN_MR2) {mBluetoothAdapter = bluetoothManager.getAdapter (); } And {mBluetoothAdapter = BluetoothAdapter.getDefaultAdapter (); }

I am trying to implement a screen-scraps application that opens a URL in which a parameter changes as it is for a loop: var data = [ '100', '101', '102', '103', '104']; (Var indexA = 0; indexA & lt; data.length; indexA ++) for {Phantom Generation ({'port': freeport}, function (pH) {ph.create page (function (page) {page.open ("http: //...++ data [index B] +" ...

Data is verified in scrap HTML and from index to array Matches. So in page 101 I scrap '101 and retrieve' and pu
