Android 获取设备号

前言

最近在对接口的时候 根据后台要求生成设备唯一id 作为key

android 获取设备号比较简单 这里记录一下

实现

  /**
     * 获取设备号
     * @param context
     * @return
     */
    public static String getDeviceId(Context context) {
        String deviceId;

        if (Build.VERSION.SDK_INT >= 29) {
            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;
    }
