android获取设备唯一标识
这里列举了获取所有可以获取到的设备唯一识别码：getDeviceId()。
我的设备是TV，获取不到IMEI，但是有以太网口，所以最好的办法是获取以太网mac作为唯一标识。
public class MobileInfoUtil {
private static String wifiTag = "wlan0";//无线标志，关闭wifi开关后获取不到
private static String localTag = "eth0";//有线标志,插不插网线都能获取到
public static String getDeviceId(Context context) {
StringBuilder deviceId = new StringBuilder();
try {
String wifiMac = getMachineHardwareAddress();//因为我的设备是tv 系统是7.0以上 所以直接不再判断系统来选择获取方案，如果不确定系统版本则使用getMac(context)
if(!isEmpty(wifiMac) && !"02:00:00:00:00:00".equals(wifiMac)){
deviceId.append("wifi");
deviceId.append(wifiMac);
Logc.e("getDeviceId : "+deviceId.toString());
return deviceId.toString();
}
//IMEI（imei）
TelephonyManager tm = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
@SuppressLint("MissingPermission") String imei = tm.getDeviceId();
if(!isEmpty(imei)){
deviceId.append("imei");
deviceId.append(imei);
Logc.e("getDeviceId : "+deviceId.toString());
return deviceId.toString();
}
//序列号（sn）
@SuppressLint("MissingPermission") String sn = tm.getSimSerialNumber();
if(!isEmpty(sn)){
deviceId.append("sn");
deviceId.append(sn);
Logc.e("getDeviceId : "+deviceId.toString());
return deviceId.toString();
}
//设备号（deviceId）
@SuppressLint("MissingPermission") String d = tm.getDeviceId();
if(!isEmpty(d)){
deviceId.append("d");
deviceId.append(d);
Logc.e("getDeviceId : "+ deviceId.toString());
return deviceId.toString();
}
//TX3 mini电视盒子只能获取Android_id
String ANDROID_ID = Settings.System.getString(context.getContentResolver(), Settings.System.ANDROID_ID);
if(!isEmpty(ANDROID_ID)){
deviceId.append("ANDROID_ID");
deviceId.append(ANDROID_ID);
Logc.e("getDeviceId : "+deviceId.toString());
return deviceId.toString();
}
//如果上面都没有， 则生成一个id：随机码
String uuid = getUUID(context);
if(!isEmpty(uuid)){
deviceId.append("id");
deviceId.append(uuid);
Logc.e("getDeviceId : ", deviceId.toString());
return deviceId.toString();
}
} catch (Exception e) {
e.printStackTrace();
deviceId.append("id").append(getUUID(context));
}
Logc.e("getDeviceId : ", deviceId.toString());
return deviceId.toString();
