Now live: A fully responsive profile. Reducing the weight of our footer. Otherwise, there was some failure. This code was originally found on Kotlin Academy. Before making the fragment, we need a view model and a layout.

The view model is simple, only containing a Boolean to indicate if the download is occurring. The base of the fragment is straightforward enough.

When the fragment loads, if we have permissions, we can set the button click listener; otherwise, we have to request permission. Some apps request these permissions on first load if they require them throughout the app. Others only request them where they are actually needed. If your app has a specific place where file downloads occur, you can just request permission there. First, we need functions to check the permissions and the request result. Note that only devices with Marshmallow API 23 or later need permissions; earlier devices had them by default.

If permission needs to be requested, our return should set the click listener when permission is granted. Either you can force the download to occur where you want with the name you provide, or you can let the user decide the name and location. I use the latter case here; the click will start an intent for creating a document with some defaults set. Downloading the file opens the output stream to the URI given and dispatches the download file coroutine. The download itself is handled on the IO thread, but the emitter results are handled on the Main thread.

This allows for the correct asynchronous updates in this case, updating the progress bar. The viewFile function takes the same URI given and opens it in an intent, if able.
