如何在Android中实现下载位置的首选项活动

Question

I have developed an app which downloads some files from server. I'm using android download manager to download files to mobile device. I want to build a settings screen asking default location to store files using preference activity. How can i implement it.

I want to show all the storage options available in mobile in preference activity. Currently i'm using below line to store the files using download manage.

Here is the code:

request.setDestinationInExternalFilesDir(context, Environment.DIRECTORY_DOWNLOADS + DownloadEntries.getFile_dest_path(), filepaths.get(i));

Please help. I'm new to android.

What you need is something called PreferenceFragment

Preference fragment is just an easy way of creating a settings screen in Android.

You can refer here for the Preference Fragments.

Since Preference Fragments doesn't support file pickers by default, you can use this library here for the file picker.

So you can tell the user to pick a folder and you can create your file in there.
