androidlint错误警报丢失权限

Question

尽管我在方法上添加了@RequiresPermission，但Android lint仍在报告"缺少权限"。代码为：

@NonNull
@RequiresPermission(Manifest.permission.READ_CONTACTS)
public static Map<String, Integer> selectContactVersions(@Nullable Collection<String> contactIds) {
if (!PermissionUtils.isPermissonGranted(ApplicationKeeper.getApplication(), Manifest.permission.READ_CONTACTS)) {
return Collections.emptyMap();
}

错误报告为：

AddressAccesssor.java:41: Call requires permission which may be rejected by user: code should explicitly check to see if permission is available (with checkPermission) or explicitly handle a potential SecurityException
38   @RequiresPermission(Manifest.permission.READ_CONTACTS)
39   public static Map<String, Integer> selectContactVersions(@Nullable Collection<String> contactIds) {
40       if (!PermissionUtils.isPermissonGranted(ApplicationKeeper.getApplication(), Manifest.permission.READ_CONTACTS)) {
41           return Collections.emptyMap();                                                          
42       }

AddressAccessor.java:126: Call requires permission which may be rejected by user: code should explicitly check to see if permission is available (with checkPermission) or explicitly handle a potential SecurityException
123       return Collections.emptyMap();
124   }
125 
126   Map<String, List<String>> contactIdPhoneListMap = selectPhones(contactIds);                 
127 
128   Map<String, AddressbookContact> addressbookContactMap = new HashMap<String, AddressbookContact>();
129   Cursor cursor = null;

我错过什么了吗？

Answer 1

我错过了什么吗？

嗯，你错过了很多。

权限需要在清单中声明，并且需要在运行时中请求。仅仅压制警告是不够的。

明确请求权限以解决问题。
