我正在尝试在 Android 10 上请求 WRITE_EXTERNAL_STORAGE 权限。我使用以下代码执行此操作：
ArrayList<String> permissions = new ArrayList<>();
if (this.checkSelfPermission(Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
permissions.add(Manifest.permission.ACCESS_FINE_LOCATION);
}
if (this.checkSelfPermission(ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
permissions.add(Manifest.permission.ACCESS_COARSE_LOCATION);
}
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q &&
this.checkSelfPermission(ACCESS_BACKGROUND_LOCATION) != PackageManager.PERMISSION_GRANTED) {
permissions.add(Manifest.permission.ACCESS_BACKGROUND_LOCATION);
}
if (this.checkSelfPermission(Manifest.permission.WRITE_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED) {
permissions.add(Manifest.permission.WRITE_EXTERNAL_STORAGE);
}
if (permissions.size() > 0) requestPermissions(permissions.toArray(new String[0]), PERMISSION_REQUEST_FINE_LOCATION);
这是清单
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.BLUETOOTH" />
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
除 WRITE_EXTERNAL_STORAGE 之外的所有其他权限均有效。当我尝试请求它时，它不会显示任何确认权限的对话框，但它只是拒绝它。为什么以及如何解决它？
我已经找到了解决方案，但问题的原因对我来说仍然是个谜。如果有人有解释，将不胜感激。基本上我的问题是这个的重复issue https://stackoverflow.com/questions/51149210/storage-access-permission-is-not-visible-in-app-info。我所要做的就是将以下行更改为
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
to
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" tools:node="replace"/>
tools:node="replace" 的作用是什么？
