android.os.Build裝置常量以及imsi號與ip地址的獲得

android.os.Build.MODEL ：裝置名
android.os.Build.BRAND： 裝置廠商
android.os.Build.VERSION.SDK：sdk版本號
一般用於版本相容的檢測或者其他功能
比如說coolpad 9930手機2.2的android系統
擇MODEL為9930，BRAND為coolpad，sdk為8
imsi號獲得
(TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE).getSubscriberId()；
獲取ip地址

 Android 關於android.os.Build介紹

關於Build類的介紹

這個類為一個獲取裝置一些初始化資訊的類，該類的主要資訊都是通過一些static的欄位獲得：

//獲取當前ANDRROID 版本

 public static int getApiLevel() {

int currentApi = 0;
  if (currentApi > 0) {
   return currentApi;
  }
  try {
   currentApi = Integer.valueOf(android.os.Build.VERSION.SDK);
  } catch (NumberFormatException e) {
   currentApi = 0;
  }
  return currentApi;
 }

//判斷機型例項

 public static boolean shouldChangeConnectForBluetooth(){
  if (android.os.Build.MODEL.equalsIgnoreCase("GT-I9300")) {
   return true;
  }
  if (android.os.Build.MODEL.equalsIgnoreCase("GT-N8000")) {
   return true;
  }
  return false;
 }

 public static boolean shouldUseModeApi() {

  // Samsung GT-I5508
  if (android.os.Build.DEVICE.equalsIgnoreCase("GT-I5508")) {
   return true;
  }

}

  // Motorola milestone 1 and 2 & motorola droid
  if (android.os.Build.DEVICE.toLowerCase().contains("milestone2")
    || android.os.Build.BOARD.toLowerCase().contains("sholes")
    || android.os.Build.PRODUCT.toLowerCase().contains("sholes")) {
   return true;
  }

  if (android.os.Build.BRAND.toLowerCase().startsWith("dell")
    && android.os.Build.DEVICE.equalsIgnoreCase("streak")) {
   return true;
  }

 public static String getCpuAbi() {
  if (isCompatible(4)) {
   Field field;
   try {
    field = android.os.Build.class.getField("CPU_ABI");
    return field.get(null).toString();
   } catch (Exception e) {
    Log.w(THIS_FILE,
      "Announce to be android 1.6 but no CPU ABI field", e);
   }

  }
  return "armeabi";
 }

3)獲取AndroidManifest.xml的資訊
1.versionCode
view plaincopy to clipboardprint?
·········10········20········30········40········50········60········70········80········90········100·······110·······120·······130·······140·······150
getPackageManager().getPackageInfo(packageName, 0).versionCode
getPackageManager().getPackageInfo(packageName, 0).versionCode
可以用Context.gerPackageName()取得packageName
2.versionName
view plaincopy to clipboardprint?
·········10········20········30········40········50········60········70········80········90········100·······110·······120·······130·······140·······150
getPackageManager().getPackageInfo(packageName, 0).versionName
getPackageManager().getPackageInfo(pName, PackageManager.GET_CONFIGURATIONS);
getPackageManager().getPackageInfo(packageName, 0).versionName
getPackageManager().getPackageInfo(pName, PackageManager.GET_CONFIGURATIONS);

4)Android判斷應用是否存在
1.通過包名判斷
view plaincopy to clipboardprint?
·········10········20········30········40········50········60········70········80········90········100·······110·······120·······130·······140·······150
public boolean checkBrowser(String packageName) {
if (packageName == null || "".equals(packageName))
return false;
try {
ApplicationInfo info = getPackageManager().getApplicationInfo(
packageName, PackageManager.GET_UNINSTALLED_PACKAGES);
return true;
} catch (NameNotFoundException e) {
return false;
}
}
public boolean checkBrowser(String packageName) {
if (packageName == null || "".equals(packageName))
return false;
try {
ApplicationInfo info = getPackageManager().getApplicationInfo(
packageName, PackageManager.GET_UNINSTALLED_PACKAGES);
return true;
} catch (NameNotFoundException e) {
return false;
}
}

2.通過Activity判斷
view plaincopy to clipboardprint?
·········10········20········30········40········50········60········70········80········90········100·······110·······120·······130·······140·······150
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setClassName("com.android.settings", //$NON-NLS-1$
"com.android.settings.InstalledAppDetails"); //$NON-NLS-1$
intent.putExtra("com.android.settings.ApplicationPkgName", //$NON-NLS-1$
mCurrentPkgName);
List acts = getPackageManager().queryIntentActivities(
intent, 0);
if (acts.size() > 0) {
startActivity(intent);
} else {
Toast.makeText(this,
getString(R.string.failed_to_resolve_activity),
Toast.LENGTH_SHORT).show();
}
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setClassName("com.android.settings", //$NON-NLS-1$
"com.android.settings.InstalledAppDetails"); //$NON-NLS-1$
intent.putExtra("com.android.settings.ApplicationPkgName", //$NON-NLS-1$
mCurrentPkgName);
List acts = getPackageManager().queryIntentActivities(
intent, 0);
if (acts.size() > 0) {
startActivity(intent);
} else {
Toast.makeText(this,
getString(R.string.failed_to_resolve_activity),
Toast.LENGTH_SHORT).show();
}

5)獲取裝置螢幕解析度
首先我們需要用到的是DisplayMetrics這個類，它可以為我們獲得手機螢幕屬性，這裡將其所在類匯入。
view plaincopy to clipboardprint?
import android.util.DisplayMetrics;
import android.util.DisplayMetrics;
得到例項物件。
view plaincopy to clipboardprint?
DisplayMetrics dm = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(dm);
DisplayMetrics dm = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(dm);
得到手機螢幕高度：
view plaincopy to clipboardprint?
dm.heightPixels;
dm.heightPixels;
得到手機螢幕寬度：
view plaincopy to clipboardprint?
dm.widthPixels;
dm.widthPixels;

得到以上手機螢幕的高度跟寬度後，即可以通過這兩個值按照比例還設定程式佈局中空間的大小。

6)獲取CPU序列號

view plaincopy to clipboardprint?
·········10········20········30········40········50········60········70········80········90········100·······110·······120·······130·······140·······150
/**
* 獲取CPU序列號
*
* @return CPU序列號(16位)
* 讀取失敗為"0000000000000000"
*/
public static String getCPUSerial() {
String str = "", strCPU = "", cpuAddress = "0000000000000000";
try {
//讀取CPU資訊
Process pp = Runtime.getRuntime().exec("cat /proc/cpuinfo");
InputStreamReader ir = new InputStreamReader(pp.getInputStream());
LineNumberReader input = new LineNumberReader(ir);
//查詢CPU序列號
for (int i = 1; i
str = input.readLine();
if (str != null) {
//查詢到序列號所在行
if (str.indexOf("Serial") > -1) {
//提取序列號
strCPU = str.substring(str.indexOf(":") + 1,
str.length());
//去空格
cpuAddress = strCPU.trim();
break;
}
}else{
//檔案結尾
break;
}
}
} catch (IOException ex) {
//賦予預設值
ex.printStackTrace();
}
return cpuAddress;
}
/**
* 獲取CPU序列號
*
* @return CPU序列號(16位)
* 讀取失敗為"0000000000000000"
*/
public static String getCPUSerial() {
String str = "", strCPU = "", cpuAddress = "0000000000000000";
try {
//讀取CPU資訊
Process pp = Runtime.getRuntime().exec("cat /proc/cpuinfo");
InputStreamReader ir = new InputStreamReader(pp.getInputStream());
LineNumberReader input = new LineNumberReader(ir);
//查詢CPU序列號
for (int i = 1; i
str = input.readLine();
if (str != null) {
//查詢到序列號所在行
if (str.indexOf("Serial") > -1) {
//提取序列號
strCPU = str.substring(str.indexOf(":") + 1,
str.length());
//去空格
cpuAddress = strCPU.trim();
break;
}
}else{
//檔案結尾
break;
}
}
} catch (IOException ex) {
//賦予預設值
ex.printStackTrace();
}
return cpuAddress;
}

7)獲取位置資訊: locationManager
1.獲取LocationManager物件
view plaincopy to clipboardprint?
String serviceString = Context.LOCATION_SERVICE;
LocationManager LocationManager = (LocationManager)getSystemService(serviceString);
String serviceString = Context.LOCATION_SERVICE;
LocationManager LocationManager = (LocationManager)getSystemService(serviceString);
2.選擇定位方法
2.1 GPS_PROVIDER: GPS
2.2 NETWORK_PROVIDER: NETWORK
以network為例：
view plaincopy to clipboardprint?
String provider = LocationManager.NETWORK_PROVIDER
Location location = locationManager.getLaskKnownLocation(provider);
double lat = location.getLatitude();
double lng = location.getLongitude();
String provider = LocationManager.NETWORK_PROVIDER
Location location = locationManager.getLaskKnownLocation(provider);
double lat = location.getLatitude();
double lng = location.getLongitude();
8)當前時間和時區

System.currentTimeMillis()獲取當前時間
時區：
TimeZone.getDefault();
