如何獲得的WiFi硬件信息在Android

Question

下面就給我基本的WiFi信息，但我想要的硬件信息：

WiFiScanReceiver.java

import java.util.List; 

import android.content.BroadcastReceiver; 
import android.content.Context; 
import android.content.Intent; 
import android.net.wifi.ScanResult; 
import android.net.wifi.WifiManager; 
import android.util.Log; 
import android.widget.Toast; 

public class WiFiScanReceiver extends BroadcastReceiver { 

    private static final String TAG = "WiFiScanReceiver"; 
    systemInfo systemInfo; 

    public WiFiScanReceiver(systemInfo systemInfo) { 
     super(); 
     this.systemInfo = systemInfo; 
    } 

    @Override 
    public void onReceive(Context c, Intent intent) { 
     List<ScanResult> results = systemInfo.wifi.getScanResults(); 
     ScanResult bestSignal = null; 
     for (ScanResult result : results) { 
      if (bestSignal == null 
        || WifiManager.compareSignalLevel(bestSignal.level, 
          result.level) < 0) bestSignal = result; 
     } 
     String message = String.format(
       "%s networks found. %s is the strongest.", results.size(), 
       bestSignal.SSID); 
     Toast.makeText(systemInfo, message, Toast.LENGTH_LONG).show(); 
     Log.d(TAG, "onReceive() message: " + message); 
    } 
} 

systemInfo.java

import java.io.BufferedReader; 
import java.io.File; 
import java.io.FileReader; 
import java.io.IOException; 
import java.util.List; 

import android.app.Activity; 
import android.app.ActivityManager; 
import android.app.ActivityManager.MemoryInfo; 
import android.content.BroadcastReceiver; 
import android.content.Context; 
import android.content.IntentFilter; 

import android.net.wifi.WifiConfiguration; 
import android.net.wifi.WifiInfo; 
import android.net.wifi.WifiManager; 
import android.os.Build; 
import android.os.Bundle; 
import android.util.Log; 
import android.view.View; 
import android.view.View.OnClickListener; 
import android.widget.Button; 
import android.widget.TextView; 
import android.widget.Toast; 

public class systemInfo extends Activity implements OnClickListener { 

    private static final String TAG = "WiFiDemo"; 
    WifiManager wifi; 
    BroadcastReceiver receiver; 
    TextView textStatus; 
    Button buttonScan; 

    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.main); 
     // Setup UI 
     textStatus = (TextView) findViewById(R.id.textStatus); 
     buttonScan = (Button) findViewById(R.id.buttonScan); 
     buttonScan.setOnClickListener(this); 
     // Setup WiFi 
     wifi = (WifiManager) getSystemService(Context.WIFI_SERVICE); 
     // Get WiFi status 
     WifiInfo info = wifi.getConnectionInfo(); 
     textStatus.append("\n\nWiFi Status: " + info.toString()); 
     // List available networks 
     List<WifiConfiguration> configs = wifi.getConfiguredNetworks(); 
     for (WifiConfiguration config : configs) { 
      textStatus.append("\n\n" + config.toString()); 
     } 
     // Register Broadcast Receiver 
     if (receiver == null) receiver = new WiFiScanReceiver(this); 
     registerReceiver(receiver, new IntentFilter(
       WifiManager.SCAN_RESULTS_AVAILABLE_ACTION)); 
     Log.d(TAG, "onCreate()"); 
     MemoryInfo mi = new MemoryInfo(); 
     ActivityManager activityManager = (ActivityManager) getSystemService(ACTIVITY_SERVICE); 
     activityManager.getMemoryInfo(mi); 
     long availableMegs = mi.availMem/1048576L; 
     System.out.println("availableMegs:::::::::::" + availableMegs); 
    } 

    @Override 
    public void onStop() { 
     unregisterReceiver(receiver); 
    } 

    public void onClick(View view) { 
     Toast.makeText(this, "On Click Clicked. Toast to that!!!", 
       Toast.LENGTH_LONG).show(); 
     if (view.getId() == R.id.buttonScan) { 
      Log.d(TAG, "onClick() wifi.startScan()"); 
      wifi.startScan(); 
      String ab = getInfo(); 
      System.out.println("CPU INFORMATON:::::::::::::\n" + ab); 
      textStatus.append("CPU INFORMATON:::::::::::::\n" + ab); 
     } 
    } 

    private String getInfo() { 
     StringBuffer sb = new StringBuffer(); 
     sb.append("abi: ").append(Build.CPU_ABI).append("\n"); 
     if (new File("/proc/cpuinfo").exists()) { 
      try { 
       BufferedReader br = new BufferedReader(new FileReader(new File(
         "/proc/cpuinfo"))); 
       String aLine; 
       while ((aLine = br.readLine()) != null) { 
        sb.append(aLine + "\n"); 
       } 
       if (br != null) { 
        br.close(); 
       } 
      } catch (IOException e) { 
       e.printStackTrace(); 
      } 
     } 
     return sb.toString(); 
    } 
} 

權限爲

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

這給了我基本的無線網絡信息。但我想要的硬件信息..

一個重要的區別就是CPU架構。雖然幾乎所有的Android設備都使用ARM CPU，但它包含不同的版本，包括armv5，armv5te，armv6，armv6與VFP，armv7，armv7與VFP，armv7與霓虹燈等。

如果您的問題是如何獲取有關WiFi芯片的硬件信息，那麼回答很簡單：Android不提供這種類型的數據，除了MAC地址（其實，這不是硬件信息）。
