Android 6.0前后权限问题

Question

• github 上下载了别人的源码，看到特意针对 android 6.0区别处理了，不清楚为什么这样做，难道 6.0 以下是不需要申请权限的？

• 下面是我下载的源码

    package com.mobile.mobileinfo.util;
  
    import android.Manifest;
    import android.app.Activity;
    import android.content.Context;
    import android.content.pm.PackageManager;
    import android.os.Build;
  
    import java.util.ArrayList;
    import java.util.List;
  
    public class PermissionUtil {
  
        // 动态权限申请
        public static void checkPermission(Activity context) {
            if (Build.VERSION.SDK_INT >= 23) {
                List<String> permissions = null;
                if (context.checkSelfPermission(Manifest.permission.READ_PHONE_STATE) != PackageManager.PERMISSION_GRANTED) {
                    permissions = new ArrayList<>();
                    permissions.add(Manifest.permission.READ_PHONE_STATE);
                }
                if (context.checkSelfPermission(Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
                    if (permissions == null) {
                        permissions = new ArrayList<>();
                    }
                    permissions.add(Manifest.permission.ACCESS_COARSE_LOCATION);
                }
                if (context.checkSelfPermission(Manifest.permission.WRITE_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED) {
                    if (permissions == null) {
                        permissions = new ArrayList<>();
                    }
                    permissions.add(Manifest.permission.WRITE_EXTERNAL_STORAGE);
                }
  
                if (context.checkSelfPermission(Manifest.permission.CAMERA) != PackageManager.PERMISSION_GRANTED) {
                    if (permissions == null) {
                        permissions = new ArrayList<>();
                    }
                    permissions.add(Manifest.permission.CAMERA);
                }
                if (permissions != null) {
                    String[] permissionArray = new String[permissions.size()];
                    permissions.toArray(permissionArray);
                    context.requestPermissions(permissionArray, 0);
                }
            }
        }
    }

以前是在xml里静态声明的，无法动态许可。
