分享一些获取手机基本信息和apk信息的函数

1.获取cpu信息 基本上耗时 几毫秒 0型号 1频率 ARMv7

public static String[] getCpuInfo() {
if (sCpuInfo == null) {
String path = "/proc/cpuinfo";
String data = "";
String[] cpuInfo = { "", "" };
String[] arrayOfString;
try {
FileReader file = new FileReader(path);
BufferedReader localBufferedReader = new BufferedReader(file, 8192);
data = localBufferedReader.readLine();
arrayOfString = data.split("\\s+");
for (int i = 2; i < arrayOfString.length; i++) {
cpuInfo[0] = cpuInfo[0] + arrayOfString[i] + " ";
}
data = localBufferedReader.readLine();
arrayOfString = data.split("\\s+");
cpuInfo[1] += arrayOfString[2];
localBufferedReader.close();

sCpuInfo = cpuInfo;
} catch (IOException e) {
}
}
return sCpuInfo;
}

public static String getCpuType() {
String cpu = android.os.Build.CPU_ABI;
if (TextUtils.isEmpty(cpu)) {
String[] cpuInfo = getCpuInfo();
if (cpuInfo != null && !TextUtils.isEmpty(cpuInfo[0])) {
cpu = cpuInfo[0].toLowerCase();
}
} else {
cpu = cpu.toLowerCase();
}
XLogger.d(TAG, "cpu:" + cpu);
return cpu;
}

2是否是特定类型，仅供参考

public static boolean isArmCpu() {
String cpu = getCpuType();
if (TextUtils.isEmpty(cpu)) {
return false;
} else {
return cpu.contains("arm");
}
}

public static boolean isArmV7Cpu() {
String cpu = getCpuType();
if (TextUtils.isEmpty(cpu)) {
return false;
} else {
return cpu.contains("v7");
}
}
3设备信息

public static String getImsi() {
TelephonyManager telephonyManager = (TelephonyManager) MApplication
.mApplication.getSystemService(Context.TELEPHONY_SERVICE);
String imsi = telephonyManager.getSubscriberId();
return imsi;
}

public static String getImei() {
TelephonyManager telephonyManager = (TelephonyManager) MApplication
.mApplication.getSystemService(Context.TELEPHONY_SERVICE);
String imei = telephonyManager.getDeviceId();
return imei;
}

public static String getWifiMac() {
WifiManager wifi = (WifiManager) MApplication
.mApplication.getSystemService(Context.WIFI_SERVICE);
WifiInfo mac = wifi.getConnectionInfo();
String macAdress = (mac != null ? mac.getMacAddress() : "");
return macAdress;
}

public static String getWifiBssid() {
WifiManager wifi = (WifiManager) MApplication
.mApplication.getSystemService(Context.WIFI_SERVICE);
WifiInfo mac = wifi.getConnectionInfo();
String bssidAdress = (mac != null ? mac.getBSSID() : "");
return bssidAdress;
}

/**
* 获取imsi前5位
*
* @param context
* @return
*/
public static String getSimInfo(Context context) {
String imsi = getImsi();
String siminfo = "00000";
if (!TextUtils.isEmpty(imsi) && imsi.length() > 4) {
siminfo = imsi.substring(0, 5);
}
return siminfo;
}

/**
* @return 返回当前手机的像素密度，xh 分辨率的是 320，h 的是 240 ，m 的是 160
*/
public static int getDefaultDisplayMetricsDensity(){
if(mScreenDensity < 0){
mScreenDensity = getDefaultDisplayMetrics().densityDpi;
}
return mScreenDensity;
}

/**
* 获取手机屏幕宽，高<br>
* 返回的 DisplayMetricx 不能被 copy ，因为该 DisplayMetricx 会随着手机的变化而变化，比如横竖屏切换时，DisplayMetricx 里面的宽、高的值就会发生对换
* @return
*/
public static DisplayMetrics getDefaultDisplayMetrics(){
if(mDisplayMetrics == null){
mDisplayMetrics = mApplication.getResources().getDisplayMetrics();
}
return mDisplayMetrics;
}

public static int getScreenWidth(Activity activity) {
DisplayMetrics dm = getDisplayMetrics(activity);
if (dm == null) return 0;
return dm.widthPixels;
}

public static int getScreenHeight(Activity activity) {
DisplayMetrics dm = getDisplayMetrics(activity);
if (dm == null) return 0;
return dm.heightPixels;
}

private static DisplayMetrics getDisplayMetrics(Activity activity) {
if (activity == null) return null;
DisplayMetrics dm = new DisplayMetrics();
activity.getWindowManager().getDefaultDisplay().getMetrics(dm);
return dm;
}

public static float getDimensValue(int resId) {
return MApplication.mApplication.getResources().getDimension(resId);
}


4.dp、px、sp转换函数
public static int convertDpToPx(int dp) {
return (int) (getDefaultDisplayMetrics().density * dp + 0.5f);
}

public static float convertDpToPx(float dp) {
return (getDefaultDisplayMetrics().density * dp);
}

public static int convertPxToDp(int px) {
return (int) (px / getDefaultDisplayMetrics().density + 0.5f);
}

public static int convertSpToPx(float sp) {
return (int) (getDefaultDisplayMetrics().scaledDensity * sp);
}

5.获取手机系统版本，获取sdk版本
public static String getOSVersion() {
return android.os.Build.VERSION.RELEASE;
}

public static int getSDKVersion() {
return android.os.Build.VERSION.SDK_INT;
}


6.根据ip获取本地mac等

//根据IP获取本地Mac
public static String getLocalMacAddressFromIp() {
Reflection reflection = new Reflection();

String mac_s = "";
try {
byte[] mac;
NetworkInterface ne = NetworkInterface.getByInetAddress(InetAddress.getByName(getLocalIpAddress()));
mac = (byte[]) reflection.invokeMethod(ne, "getHardwareAddress", new Object[] {});
mac_s = byte2hex(mac);
} catch (Exception e) {
e.printStackTrace();
}
return mac_s;
}

public static String getLocalIpAddress() {
try {
String ipv4;
List<NetworkInterface> nilist = Collections.list(NetworkInterface.getNetworkInterfaces());
for (NetworkInterface ni: nilist)
{
List<InetAddress> ialist = Collections.list(ni.getInetAddresses());
for (InetAddress address: ialist){
if (!address.isLoopbackAddress() && InetAddressUtils.isIPv4Address(ipv4=address.getHostAddress()))
{
return ipv4;
}
}
}

} catch (SocketException ex) {
}
return null;
}
public static String byte2hex(byte[] b) {
        StringBuffer hs = new StringBuffer(b.length);
        String stmp = "";
        int len = b.length;
        for (int n = 0; n < len; n++) {
            stmp = Integer.toHexString(b
& 0xFF);
            if (stmp.length() == 1)
                hs = hs.append("0").append(stmp);
            else {
                hs = hs.append(stmp);
            }
        }
        return String.valueOf(hs);
    }
