Android获取设备号SSAID (Android ID) 和 IMEI

1、基本方式 

/**
     * 获取手机的设备号.
     * @param context 上下文
     * @return 设备号
     */
    @SuppressLint("HardwareIds")
    public static String getIMEIDeviceId(Context context) {
 
        String deviceId;
        //如果sdk版本大于等于29
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) {
            deviceId = Settings.Secure.getString(context.getContentResolver(), Settings.Secure.ANDROID_ID);
        } else {
            final TelephonyManager mTelephony = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
                if (context.checkSelfPermission(Manifest.permission.READ_PHONE_STATE) != PackageManager.PERMISSION_GRANTED) {
                    return "";
                }
            }
            assert mTelephony != null;
            if (mTelephony.getDeviceId() != null) {
                if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
                    deviceId = mTelephony.getImei();
                } else {
                    deviceId = mTelephony.getDeviceId();
                }
            } else {
                deviceId = Settings.Secure.getString(context.getContentResolver(), Settings.Secure.ANDROID_ID);
            }
        }
 
        return deviceId;
    }

 2、官方推荐

if (context.applicationInfo.targetSdkVersion >= 29 && Build.VERSION.SDK_INT >= 29 ){
		//大于等于29使用特殊方法
      getUniqueID(context);
 }
  private fun getUniqueID(context: Context): String? {
    var id: String? = null
    val androidId = Settings.Secure.getString(context.contentResolver, Settings.Secure.ANDROID_ID)
    if (!Tool.isEmpty(androidId) && "9774d56d682e549c" != androidId) {
      try {
        val uuid = UUID.nameUUIDFromBytes(androidId.toByteArray(charset("utf8")))
        id = uuid.toString()
      } catch (e: Exception) {
        e.printStackTrace()
      }
    }
    if (Tool.isEmpty(id)) {
      id = getUUID()
    }
    return if (Tool.isEmpty(id)) UUID.randomUUID().toString() else id
  }
  private fun getUUID(): String? {
    var serial: String? = null
    val m_szDevIDShort = "35" + Build.BOARD.length % 10 + Build.BRAND.length % 10 + (if (null != Build.CPU_ABI) Build.CPU_ABI.length else 0) % 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 位
    if (Build.VERSION.SDK_INT <= 29) {
      try {
        serial = if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
          Build.getSerial()
        } else {
          Build.SERIAL
        }
        //API>=9 使用serial号
        return UUID(m_szDevIDShort.hashCode().toLong(), serial.hashCode().toLong()).toString()
      } catch (exception: java.lang.Exception) {
        serial = "serial" // 随便一个初始化
      }
    } else {
      serial = Build.UNKNOWN // 随便一个初始化
    }
 
    //使用硬件信息拼凑出来的15位号码
    return UUID(m_szDevIDShort.hashCode().toLong(), serial.hashCode().toLong()).toString()
  }
