"Required permission was denied!" when requesting WRITE_EXTERNAL_STORAGE

I am trying to request WRITE_EXTERNAL_STORAGE permission on Android 10. I do that using the following code:

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);

Here is the manifest

<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" />

All other permissions work except WRITE_EXTERNAL_STORAGE. When I try to request it, it does not display any dialog for confirming permission, but it simply denies it. Why and how can I fix it?

I have discovered the solution, however the cause of the problem is still a mystery to me. If anyone has an explination, it would be greatly appreciated. Basically my issue is a duplicate of this issue. All I had to do is to change the following line from

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

to

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" tools:node="replace"/>

What does tools:node="replace" do?

You can use Android Runtime Permission Library by nabinbhandari in you build.gradle app module file write this

 //Android Runtime Permission Library
        implementation 'com.nabinbhandari.android:permissions:3.8'

In your Manifest file write

    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

and in Activity declare these variables

    String[] permissions = new String[]{READ_EXTERNAL_STORAGE, WRITE_EXTERNAL_STORAGE};
    String rationale = "Please provide storage permission to proceed ...";

And in your onCreate() Method write this

Permissions.Options options = new Permissions.Options()
                .setRationaleDialogTitle("Info")
                .setSettingsDialogTitle("Warning");

        Permissions.check(MainActivity.this, permissions, rationale, options, new PermissionHandler() {
            @Override
            public void onGranted() {
                // do your task.
                Toast.makeText(MainActivity.this, "Permissions granted", Toast.LENGTH_SHORT).show();
            }

            @Override
            public void onDenied(Context context, ArrayList<String> deniedPermissions) {
                // permission denied
                Toast.makeText(MainActivity.this, "Permissions denied", Toast.LENGTH_SHORT).show();

            }
        });

You can handle requested permission using this method (works with android 10), Here is the documentation.

    @Override
    public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
        super.onRequestPermissionsResult(requestCode, permissions, grantResults);
        if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
            switch (requestCode) {
                case PERMISSION_REQUEST_ID_STORAGE:
                    // permisstion granted by user
                    break;
            }
        } else {
            switch (requestCode) {
                case PERMISSION_REQUEST_ID_STORAGE:
                    // permission denied by user
                    break;
            }
        }
    }
