Android 關於android.os.Build介紹
關於Build類的介紹
這個類爲一個獲取設備一些初始化信息的類，該類的主要信息都是通過一些static的字段獲得：
| public static final String | BOARD | The name of the underlying board, like "goldfish".（設備廠商） |
| public static final String | BOOTLOADER | The system bootloader version number. |
| public static final String | BRAND | The brand (e.g., carrier) the software is customized for, if any. |
| public static final String | CPU_ABI | The name of the instruction set (CPU type + ABI convention) of native code. |
| public static final String | CPU_ABI2 | The name of the second instruction set (CPU type + ABI convention) of native code. |
| public static final String | DEVICE | The name of the industrial design. |
| public static final String | DISPLAY | A build ID string meant for displaying to the user |
| public static final String | FINGERPRINT | A string that uniquely identifies this build. |
| public static final String | HARDWARE | The name of the hardware (from the kernel command line or /proc). |
| public static final String | HOST | |
| public static final String | ID | Either a changelist number, or a label like "M4-rc20". |
| public static final String | MANUFACTURER | The manufacturer of the product/hardware. |
| public static final String | MODEL | The end-user-visible name for the end product.（設備名） |
| public static final String | PRODUCT | The name of the overall product. |
| public static final String | RADIO |
This field is deprecated. The radio firmware version is frequently not available when this class is initialized, leading to a blank or "unknown" value for this string. Use getRadioVersion() instead. |
| public static final String | SERIAL | A hardware serial number, if available. |
| public static final String | TAGS | Comma-separated tags describing the build, like "unsigned,debug". |
| public static final long | TIME | |
| public static final String | TYPE | The type of build, like "user" or "eng". |
| public static final String | USER |
//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;
}
//判斷機型實例
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的信息
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)獲取設備屏幕分辨率
首先我們需要用到的是DisplayMetrics這個類，它可以爲我們獲得手機屏幕屬性，這裏將其所在類導入。
view plaincopy to clipboardprint?
import android.util.DisplayMetrics;
import android.util.DisplayMetrics;
得到實例對象。
view plaincopy to clipboardprint?
DisplayMetrics dm = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(dm);
DisplayMetrics dm = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(dm);
得到手機屏幕高度：
view plaincopy to clipboardprint?
dm.heightPixels;
dm.heightPixels;
得到手機屏幕寬度：
view plaincopy to clipboardprint?
dm.widthPixels;
dm.widthPixels;
得到以上手機屏幕的高度跟寬度後，即可以通過這兩個值按照比例還設定程序佈局中空間的大小。
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)
* 讀取失敗爲"0000000000000000"
*/
public static String getCPUSerial() {
String str = "", strCPU = "", cpuAddress = "0000000000000000";
try {
//讀取CPU信息
Process pp = Runtime.getRuntime().exec("cat /proc/cpuinfo");
InputStreamReader ir = new InputStreamReader(pp.getInputStream());
LineNumberReader input = new LineNumberReader(ir);
//查找CPU序列號
for (int i = 1; i
str = input.readLine();
if (str != null) {
//查找到序列號所在行
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{
//文件結尾
break;
}
}
} catch (IOException ex) {
//賦予默認值
ex.printStackTrace();
}
return cpuAddress;
}
/**
* 獲取CPU序列號
*
* @return CPU序列號(16位)
* 讀取失敗爲"0000000000000000"
*/
public static String getCPUSerial() {
String str = "", strCPU = "", cpuAddress = "0000000000000000";
try {
//讀取CPU信息
Process pp = Runtime.getRuntime().exec("cat /proc/cpuinfo");
InputStreamReader ir = new InputStreamReader(pp.getInputStream());
LineNumberReader input = new LineNumberReader(ir);
//查找CPU序列號
for (int i = 1; i
str = input.readLine();
if (str != null) {
//查找到序列號所在行
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{
//文件結尾
break;
}
}
} catch (IOException ex) {
//賦予默認值
ex.printStackTrace();
}
return cpuAddress;
}
7)獲取位置信息: locationManager
1.獲取LocationManager對象
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爲例：
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();
