OnePlus 1中是否含有棉花糖？是的，它含有棉花糖。设备应用程序设置中是否已接受权限？因为我有MinSDK版本23，运行时权限应该有效。或者我是否仍需要检查设备应用程序设置以获取权限？发现导致此行为的问题。我正在向子活动请求权限。当我尝试使用ActivityCompat.requestPermissions（getParent（），新字符串[]{android.Manifest.permission.WRITE_EXTERNAL_STORAGE}，1）；它不知怎么起作用了。但不清楚原因。谢谢大家，这是我第一次尝试。但事实并非如此working@priyankbrahmbhatt尝试添加context ContextCompat.checkSelfPermission（这个，android.Manifest.permission.WRITE_EXTERNAL_STORAGE）=PackageManager.permission_grated）与ContextCompat的结果相同
