最近又涉及到了獲取設(shè)備信息的東西沐鼠，因為之前做過但是沒有做記錄徽惋，導(dǎo)致這次又做的時候又重新去百度回怜，所以這次做完了要記錄一下距辆。

1.獲取手機廠商

public String getDeviceBrand(){
    return android.os.Build.BRAND;
}

2.獲取設(shè)備型號

public String getSystemModel() {
    return android.os.Build.MODEL;
}

3.獲取當(dāng)前系統(tǒng)版本

public String getSystemVersion() {
    return android.os.Build.VERSION.RELEASE;
}

4.獲取運營商的名字

 public static String getOperatorName(Context context) {
    /*
     * getSimOperatorName()就可以直接獲取到運營商的名字
     * 也可以使用IMSI獲取翘紊，getSimOperator()蔽氨，然后根據(jù)返回值判斷，例如"46000"為移動
     * IMSI相關(guān)鏈接：http://baike.baidu.com/item/imsi
     */
    TelephonyManager telephonyManager = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
    // getSimOperatorName就可以直接獲取到運營商的名字
    return telephonyManager.getSimOperatorName();
}

5.獲取聯(lián)網(wǎng)方式

public static String getNetworkState(Context context) {
    String strNetworkType = "";
    ConnectivityManager connManager = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE); // 獲取網(wǎng)絡(luò)服務(wù)
    //NetworkInfo networkInfo = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE).getActiveNetworkInfo();
    NetworkInfo networkInfo = connManager.getActiveNetworkInfo();
    if (networkInfo != null && networkInfo.isAvailable())
    {
        if (networkInfo.getType() == ConnectivityManager.TYPE_WIFI)
        {
            strNetworkType = "WIFI";
        }
        else if (networkInfo.getType() == ConnectivityManager.TYPE_MOBILE)
        {
            String _strSubTypeName = networkInfo.getSubtypeName();

            // TD-SCDMA   networkType is 17
            int networkType = networkInfo.getSubtype();
            switch (networkType) {
                case TelephonyManager.NETWORK_TYPE_GPRS:
                case TelephonyManager.NETWORK_TYPE_EDGE:
                case TelephonyManager.NETWORK_TYPE_CDMA:
                case TelephonyManager.NETWORK_TYPE_1xRTT:
                case TelephonyManager.NETWORK_TYPE_IDEN: //api<8 : replace by 11
                    strNetworkType = "2G";
                    break;
                case TelephonyManager.NETWORK_TYPE_UMTS:
                case TelephonyManager.NETWORK_TYPE_EVDO_0:
                case TelephonyManager.NETWORK_TYPE_EVDO_A:
                case TelephonyManager.NETWORK_TYPE_HSDPA:
                case TelephonyManager.NETWORK_TYPE_HSUPA:
                case TelephonyManager.NETWORK_TYPE_HSPA:
                case TelephonyManager.NETWORK_TYPE_EVDO_B: //api<9 : replace by 14
                case TelephonyManager.NETWORK_TYPE_EHRPD:  //api<11 : replace by 12
                case TelephonyManager.NETWORK_TYPE_HSPAP:  //api<13 : replace by 15
                    strNetworkType = "3G";
                    break;
                case TelephonyManager.NETWORK_TYPE_LTE:    //api<11 : replace by 13
                    strNetworkType = "4G";
                    break;
                default:
                    // http://baike.baidu.com/item/TD-SCDMA 中國移動 聯(lián)通 電信 三種3G制式
                    if (_strSubTypeName.equalsIgnoreCase("TD-SCDMA") || _strSubTypeName.equalsIgnoreCase("WCDMA") || _strSubTypeName.equalsIgnoreCase("CDMA2000"))
                    {
                        strNetworkType = "3G";
                    }
                    else
                    {
                        strNetworkType = _strSubTypeName;
                    }

                    break;
            }
        }
    }
    return strNetworkType;
}

6.獲取屏幕分辨率

public static Integer[] getScreenWH(Context context) {
    DisplayMetrics dm = new DisplayMetrics();
    ((Activity) context).getWindowManager().getDefaultDisplay()
            .getMetrics(dm);

    return new Integer[]{dm.widthPixels, dm.heightPixels};
}

7.檢查當(dāng)前網(wǎng)絡(luò)是否可用

public static boolean isNetworkAvailable(Context context) {
    /* 獲取手機所有連接管理對象（包括對wi-fi,net等連接的管理） */
    if (null == context) {
        context = MyApplication.getInstance();
    }
    ConnectivityManager connectivityManager = (ConnectivityManager) context
            .getSystemService(Context.CONNECTIVITY_SERVICE);

    if (connectivityManager == null) {
        return false;
    } else {
        NetworkInfo[] networkInfo = connectivityManager.getAllNetworkInfo();

        if (networkInfo != null && networkInfo.length > 0) {
            for (int i = 0; i < networkInfo.length; i++) {
                /* 判斷當(dāng)前網(wǎng)絡(luò)狀態(tài)是否為連接狀態(tài) */
                if (networkInfo[i].getState() == NetworkInfo.State.CONNECTED) {
                    return true;
                }
            }
        }
    }
    return false;
}
