霜风渐紧寒侵被，听孤雁声嘹唳，一声声送一声悲。《御街行》中的这句诗用来形容这个季节的北京真是再合适不过了，霜风阵阵，跑步的时候也越来越舍不得脱去外套了，考验毅力的时刻到了！
言归正传，开发Android手机APP时，经常需要获取手机的相关信息，比如系统版本号、屏幕分辨率和MAC等。今天咱们就来聊一聊如何获取手机的相关信息。
首先我们可以新建一个类，需要有一个上下文的成员变量，至于其他的，不啰嗦，直接上代码！
获取屏幕分辨率：
//获取分辨率
String resolution = "";
DisplayMetrics dm = mContext.getResources().getDisplayMetrics();
int screenWidth = dm.widthPixels;
int screenHeight = dm.heightPixels;
resolution = screenWidth + "*" + screenHeight;获取运营商：
//获取运营商
String providersName = "";
TelephonyManager telephonyManager = (TelephonyManager) mContext.getSystemService(Context.TELEPHONY_SERVICE);
String IMSI = telephonyManager.getSubscriberId();
if (IMSI != null) {
if (IMSI.startsWith("46000") || IMSI.startsWith("46002") || IMSI.startsWith("46007")) {
providersName = "中国移动";
} else if (IMSI.startsWith("46001") || IMSI.startsWith("46006")) {
providersName = "中国联通";
} else if (IMSI.startsWith("46003")) {
providersName = "中国电信";
} else {
providersName = "其他";
}
} else {
providersName = "无法获取运营商信息";
}获取联网方式：
/获取联网方式
String access = "";
ConnectivityManager connectionManager = (ConnectivityManager) mContext.getSystemService(CONNECTIVITY_SERVICE);
NetworkInfo netWorkInfo = connectionManager.getActiveNetworkInfo();
access = netWorkInfo.getTypeName();获取操作系统版本：
/获取操作系统版本
String osVersion = "";
osVersion = android.os.Build.VERSION.RELEASE;获取APP版本：
//获取APP版本
try {
PackageManager pm = mContext.getPackageManager();
PackageInfo pi = pm.getPackageInfo(mContext.getPackageName(), PackageManager.GET_ACTIVITIES);
if (pi != null) {
errorPram.setAppVersion(pi.versionName == null ? "" : pi.versionName);
}
} catch (NameNotFoundException e) {
}获取设备ID：
//获取设备ID
String deviceId = "";
deviceId = telephonyManager.getDeviceId();获取MAC：
//获取MAC
String macAddress = "";
WifiManager wifiManager = (WifiManager) mContext.getSystemService(Context.WIFI_SERVICE);
WifiInfo info = (null == wifiManager ? null : wifiManager.getConnectionInfo());
if (null != info) {
macAddress = info.getMacAddress();
}获取手机型号：
//获取手机型号
String model = "";
model = android.os.Build.MODEL;获取IMEI：
//获取IMEI
String imei = "";
TelephonyManager tm = (TelephonyManager) mContext.getSystemService(Activity.TELEPHONY_SERVICE);
if (tm != null) {
imei = tm.getDeviceId();
}获取错误报告：
//获取错误报告
String report = "";
Writer writer = new StringWriter();
PrintWriter printWriter = new PrintWriter(writer);
ex.printStackTrace(printWriter);
Throwable cause = ex.getCause();
while (cause != null) {
cause.printStackTrace(printWriter);
cause = cause.getCause();
}
printWriter.close();
report = writer.toString();需要注意的是，如果要获取错误报告，那么这个类需要继承Thread.UncaughtExceptionHandler接口，从而获取产生的异常的实例，也就是代码第四行当中的ex。
使用手机进行测试，可以得到相应信息如下：
