请求WRITE_EXTERNAL_STORAGE权限的正确方法 [英] Proper Way of Requesting WRITE_EXTERNAL_STORAGE Permission

问题描述

我一直在努力弄清楚存储系统在Android上是如何工作的.现在，我一直在要求获得WRITE_EXTERNAL_STORAGE的许可，并且我使用的是Android 7.1.1.这是我的代码:

I have struggled trying to figure out how the storage system work on Android. Now I am stuck at requesting permission for WRITE_EXTERNAL_STORAGE, and I am using Android 7.1.1. Here is my code:

int check = ActivityCompat.checkSelfPermission(this, Manifest.permission.WRITE_EXTERNAL_STORAGE);
        if (check == PackageManager.PERMISSION_GRANTED) {
            //Do something
        } else {
            requestPermissions(new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE},1024);
        }

更新:所以该代码确实有效，以前没用过，因为我在AndroidManifest.xml中输入错误，谢谢您的所有帮助！

UPDATE: So the code does work, it didn't work before because I had a typo in AndroidManifest.xml, thank you for all of your help!
