在APP开发时,经常会遇到要获取手机状态信息的场景,像升级时获取版本号,像发生异常时要收集手机信息等等。有些软件还要根据Mac地址来判定当前用户以前是否登录过。下面将一一介绍获取这些手机状态信息的方法。
<uses-permission android:name="android.permission.READ_PHONE_STATE"/>
下面是Build类的字段所对应的信息
String BOARD The name of the underlying board, like "goldfish".基板名
String BOOTLOADER The system bootloader version number.
String BRAND The brand (e.g., carrier) the software is customized for, if any.品牌名
String CPU_ABI The name of the instruction set (CPU type + ABI convention) of native code.
String CPU_ABI2 The name of the second instruction set (CPU type + ABI convention) of native code.
String DEVICE The name of the industrial design.品牌型号名,如小米4对应cancro
String DISPLAY A build ID string meant for displaying to the user
String FINGERPRINT A string that uniquely identifies this build.包含制造商,设备名,系统版本等诸多信息
String HARDWARE The name of the hardware (from the kernel command line or /proc).
String HOST
String ID Either a changelist number, or a label like "M4-rc20".
String MANUFACTURER The manufacturer of the product/hardware.
String MODEL The end-user-visible name for the end product.
String PRODUCT The name of the overall product.
String RADIO The radio firmware version number.
String SERIAL A hardware serial number, if available.
String TAGS Comma-separated tags describing the build, like "unsigned,debug".
long TIME 当前时间,毫秒值
String TYPE The type of build, like "user" or "eng".
String UNKNOWN Value used for when a build property is unknown.
String USER
//运用反射得到build类里的字段
Field[] fields = Build.class.getDeclaredFields();
//遍历字段名数组
for (Field field : fields) {
try {
//将字段都设为public可获取
field.setAccessible(true);
//filed.get(null)得到的即是设备信息
haspmap.put(field.getName(), field.get(null).toString());
Log.d("CrashHandler", field.getName() + " : " + field.get(null));
} catch (Exception e) {
}
}

Context.getSystemService()这个方法是非常实用的方法,只须在参数里输入一个String 字符串常量就可得到对应的服务管理方法,可以用来获取绝大部分的系统信息,各个常量对应的含义如下。
WINDOW_SERVICE (“window”)
The top-level window manager in which you can place custom windows. The returned object is a WindowManager.
LAYOUT_INFLATER_SERVICE (“layout_inflater”)
A LayoutInflater for inflating layout resources in this context.
ACTIVITY_SERVICE (“activity”)
A ActivityManager for interacting with the global activity state of the system.
POWER_SERVICE (“power”)
A PowerManager for controlling power management.
NOTIFICATION_SERVICE (“notification”)
A NotificationManager for informing the user of background events.
KEYGUARD_SERVICE (“keyguard”)
A KeyguardManager for controlling keyguard.
LOCATION_SERVICE (“location”)
A LocationManager for controlling location (e.g., GPS) updates.
SEARCH_SERVICE (“search”)
A SearchManager for handling search.
VIBRATOR_SERVICE (“vibrator”)
A Vibrator for interacting with the vibrator hardware.
CONNECTIVITY_SERVICE (“connection”)
A ConnectivityManager for handling management of network connections.
WIFI_SERVICE (“wifi”)
A WifiManager for management of Wi-Fi connectivity.
WIFI_P2P_SERVICE (“wifip2p”)
A WifiP2pManager for management of Wi-Fi Direct connectivity.
INPUT_METHOD_SERVICE (“input_method”)
An InputMethodManager for management of input methods.
UI_MODE_SERVICE (“uimode”)
An UiModeManager for controlling UI modes.
DOWNLOAD_SERVICE (“download”)
A DownloadManager for requesting HTTP downloads
BATTERY_SERVICE (“batterymanager”)
A BatteryManager for managing battery state
JOB_SCHEDULER_SERVICE (“taskmanager”)
A JobScheduler for managing scheduled tasks
NETWORK_STATS_SERVICE (“netstats”)
A NetworkStatsManager for querying network usage statistics.
Note: System services obtained via this API may be closely associated with the Context in which they are obtained from. In general, do not share the service objects between various different contexts (Activities, Applications, Services, Providers, etc.)
Parameters
name
The name of the desired service.
需要权限:
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
/**获得IP地址,分为两种情况,一是wifi下,二是移动网络下,得到的ip地址是不一样的*/

我们知道mac地址是网卡的唯一标识,通过这个可以判断网络当前连接的手机设备有几台。代码如下:
public static String getMacAddress(){
/*获取mac地址有一点需要注意的就是android 6.0版本后,以下注释方法不再适用,不管任何手机都会返回"02:00:00:00:00:00"这个默认的mac地址,这是googel官方为了加强权限管理而禁用了getSYstemService(Context.WIFI_SERVICE)方法来获得mac地址。*/
// String macAddress= "";
// WifiManager wifiManager = (WifiManager) MyApp.getContext().getSystemService(Context.WIFI_SERVICE);
// WifiInfo wifiInfo = wifiManager.getConnectionInfo();
// macAddress = wifiInfo.getMacAddress();
// return macAddress;
String macAddress = null;
StringBuffer buf = new StringBuffer();
NetworkInterface networkInterface = null;
try {
networkInterface = NetworkInterface.getByName("eth1");
if (networkInterface == null) {
networkInterface = NetworkInterface.getByName("wlan0");
}
if (networkInterface == null) {
return "02:00:00:00:00:02";
}
byte[] addr = networkInterface.getHardwareAddress();
for (byte b : addr) {
buf.append(String.format("%02X:", b));
}
if (buf.length() > 0) {
buf.deleteCharAt(buf.length() - 1);
}
macAddress = buf.toString();
} catch (SocketException e) {
e.printStackTrace();
return "02:00:00:00:00:02";
}
return macAddress;
}
/**获取手机的IMEI号码*/
public static String getPhoneIMEI() {
TelephonyManager mTm = (TelephonyManager) MyApp.getContext().getSystemService(Context.TELEPHONY_SERVICE);
String imei = mTm.getDeviceId();
String imsi = mTm.getSubscriberId();
String mtype = android.os.Build.MODEL; // 手机型号
String numer = mTm.getLine1Number(); // 手机号码,有的可得,有的不可得
return imei;
}
