MimeTypeMap | Provides a huge dictionary of file extensions to mime types | Browser Plugin library

I see that in the downloadFile method > inside try, you are creating the Uri of the url by parsing it. But, the url cannot be converted to Uri as it does not exist on the device!

Replace

I simple changed this

Reading both exceptions i can understand that the permissions i granted for Media folder inside Android may not be correct

You cannot grant anything. Instead you were granted access to Whatsapp Media folder. But only while using SAF.

Now you have a bunch of irrelevant code where you define providers and paths. No good. Scary code.

And while you may succeed in listing all the files you are not using the uries of all those files (You should put them in an list to be used by the recycle view) but with again all kind of tricks build up a File path.

So throw away all those provider and path definitions.

Just list the content of the Media folder with a direct query(). If you see the ".Statuses" folder listed then go and list that folder. And.. save the obtained file uries to an Uri list.

You started with SAF and converted to File. Dont do such nasty things. Your SAF permissions are no File permissions. You do not need any permission in manifest to use SAF.

Turns out that I found a solution to my problem, if anyone else ever faces the same issue. I actually modified the ExtAudioRecorder class and now everything seems to be working right.

Especially after changing this line:

audioRecorder = new AudioRecord(aSource, sRate, nChannels + 1, aFormat, bufferSize);

into this:

audioRecorder = new AudioRecord(aSource, sRate, nChannels, aFormat, bufferSize);

I think the problem was lying somewhere there.

Here's the modified code for ExtAudioRecorder.java file:

If you're only trying to upload the video files, why not use a custom RequestBody which means you're not reading the entire file into memory? Like so:

Call stream.Position = 0 before you return it (or if there is a reason CreateTar should return a stream that is pointing to the end of itself, capture it into a variable and reset the position before you pass it into File(...))

Its because FirebaseStorage uploads your images asynchronously. Here is a sample:

Based on @blackapps suggestions, I did the following changes.

#1. To add a new section in the AndroidManifest.xml:

There are two major issues in your code. The first one, you are defining the following StorageReference object like so:
