IMEI等の取得

public String getPhoneInfo(Context context) {  
   TelephonyManager tm = (TelephonyManager) context  
           .getSystemService(Context.TELEPHONY_SERVICE);  
   StringBuilder sb = new StringBuilder();  

   sb.append("
DeviceId(IMEI) = " + tm.getDeviceId());//    IMEI    
   sb.append("
DeviceSoftwareVersion = " + tm.getDeviceSoftwareVersion());  
   sb.append("
Line1Number = " + tm.getLine1Number());  
   sb.append("
NetworkCountryIso = " + tm.getNetworkCountryIso());  
   sb.append("
NetworkOperator = " + tm.getNetworkOperator());  
   sb.append("
NetworkOperatorName = " + tm.getNetworkOperatorName());  
   sb.append("
NetworkType = " + tm.getNetworkType());  
   sb.append("
PhoneType = " + tm.getPhoneType());  
   sb.append("
SimCountryIso = " + tm.getSimCountryIso());  
   sb.append("
SimOperator = " + tm.getSimOperator());

SimState = " + tm.getSimState());  
   sb.append("
SubscriberId(IMSI) = " + tm.getSubscriberId());  
   sb.append("
VoiceMailNumber = " + tm.getVoiceMailNumber());  
   return sb.toString();

画面に関する情報の取得

    private int screenWidth;  
    private int screenHeigth;  
    private float screenDensity;  
    private int screenDpi;  
    private float screenScaledDensity;  

   public void getScreenInfo(Activity activity) {  
       DisplayMetrics metric = new DisplayMetrics();  
       activity.getWindowManager().getDefaultDisplay().getMetrics(metric);  
       screenWidth = metric.widthPixels;  
       screenHeigth = metric.heightPixels;  
       screenDensity = metric.density;  
       screenDpi = metric.densityDpi;  
       screenScaledDensity = metric.scaledDensity;  
   }  

画面幅の取得

     * @return the screen width 
     */  
    @SuppressWarnings("deprecation")

            return size.x;  
        }  
        return display.getWidth();  
    }  

画面の高さを取得

/** 
     * Get the screen height. 
     *  
     * @param context 
     * @return the screen height 
     */

            return size.y;  
        }  
        return display.getHeight();  
    }  

ネットワーク接続ステータスの取得

public boolean isConnect(Context context) {  
        try {

                    .getSystemService(Context.CONNECTIVITY_SERVICE);

                    if (mobile != null && mobile.equals(State.CONNECTED)) {  
                        return true;  
                    }  
                }  

                NetworkInfo wifiNetworkInfo = conMan  
                        .getNetworkInfo(ConnectivityManager.TYPE_WIFI);  
                if (wifiNetworkInfo != null) {  
                    State wifi = wifiNetworkInfo.getState();

                        return true;  
                    }
