Android获取手机唯一标识

1.许多应用都有这样的需求获取你的手机唯一标识，当你卸载软件重新安装的时候也要保证这个唯一标识不变，所以只能根据手机硬件的去获取到唯一标识，
2.有好多跟硬件相关都会有各种权限问题。一种很简单直接获取到READ_PHONE_STATE的权限，读取到设备串号.
3.如果是Android6.0系统需要去申请权限，否则会奔溃，这是6.0的新特性。虽然没有什么暖用。

（1）这种方式不加密，直接获取串号

if (EasyPermissions.hasPermissions(context, Manifest.permission.READ_PHONE_STATE)) {

// 已经有摄像头权限了，可以使用该权限完成app的相应的操作了

Log.e(“执行请求”, “获取true”);

TelephonyManager telephonyManager = (TelephonyManager) context

.getSystemService(Context.TELEPHONY_SERVICE);

deviceId = telephonyManager.getDeviceId();// imei

if (deviceId == null) {

deviceId = telephonyManager.getSubscriberId();// imsi

}

if (deviceId == null) {

deviceId = telephonyManager.getSimSerialNumber();

}

if (deviceId == null) {

deviceId = “noimei” + telephonyManager.getNetworkOperatorName();

}

Log.e("手机唯一标志deviceId", deviceId);

// textView.setText(“设备号”+deviceId);

return deviceId;

} else {
EasyPermissions.requestPermissions(context, "请您为“软件”不打开读取手机标志权限",
2, Manifest.permission.READ_PHONE_STATE);
return null;
}

（2） 这种方式为多种硬件相关组合到一块，加密方式

//获取手机唯一串号

String szImei = null;

if (EasyPermissions.hasPermissions(context, Manifest.permission.READ_PHONE_STATE)) {

TelephonyManager TelephonyMgr = (TelephonyManager) context

.getSystemService(Context.TELEPHONY_SERVICE);

szImei = TelephonyMgr.getDeviceId();

} else {

// EasyPermissions.requestPermissions(context, “请您为打开唯一标志权限”,

// 2, Manifest.permission.READ_PHONE_STATE);

}

String m_szDevIDShort = "35" + //we make this look like a valid IMEI
Build.BOARD.length() % 10 +
Build.BRAND.length() % 10 +
Build.CPU_ABI.length() % 10 +
Build.DEVICE.length() % 10 +
Build.DISPLAY.length() % 10 +
Build.HOST.length() % 10 +
Build.ID.length() % 10 +
Build.MANUFACTURER.length() % 10 +
Build.MODEL.length() % 10 +
Build.PRODUCT.length() % 10 +
Build.TAGS.length() % 10 +
Build.TYPE.length() % 10 +
Build.USER.length() % 10; //13 digits

String m_szAndroidID = Settings.Secure.getString(context.getContentResolver(), Settings.Secure.ANDROID_ID);

WifiManager wm = (WifiManager) context.getSystemService(Context.WIFI_SERVICE);
String m_szWLANMAC = wm.getConnectionInfo().getMacAddress();

String m_szLongID = szImei + m_szDevIDShort
+ m_szAndroidID + m_szWLANMAC;
// compute md5
MessageDigest m = null;
try {
m = MessageDigest.getInstance("MD5");
} catch (NoSuchAlgorithmException e) {
e.printStackTrace();
}
m.update(m_szLongID.getBytes(), 0, m_szLongID.length());
// get md5 bytes
byte p_md5Data[] = m.digest();
// create a hex string
String m_szUniqueID = new String();
for (int i = 0; i < p_md5Data.length; i++) {
int b = (0xFF & p_md5Data[i]);
// if it is a single digit, make sure it have 0 in front (proper padding)
if (b <= 0xF)
m_szUniqueID += "0";
// add number to string
m_szUniqueID += Integer.toHexString(b);
}   // hex string to uppercase
m_szUniqueID = m_szUniqueID.toUpperCase();

Log.e("手机唯一标志deviceId", m_szUniqueID);
