Upload recorded file to AWS S3 storage or google drive

I have created an app to record the audio in the android wear but I am not able to transfer that recorded file to mobile phone as there is no dedicated file manager in Samsung galaxy watch 4. So for that I need to upload the the recorded file to the AWS S3 STORAGE.
Here is the code for audio recording.

i want to solve my issue

Please wrap with function and make annotations there instead of mentioning in the main content view and wrap using UI thread.And refer sample github agora sdk github for reference - https://github.com/AgoraIO-Community/VideoUIKit-Android

Altbeacon library not able to find/trace transmitting beacon near device

I am using altbeacon library for contact tracing. But i am not able to find/trace my device when it comes near my other scanning phone. I have two mobiles basically, one i am using for scanning and other as beacon transmitter. I am able to transmit as beacon from my phone number 2. I tested also in Locate Beacon app. It showed my phone in that. But when i am testing on my phone number 1, its not working. I am not able to see any beacon on any logs even though my didDetermineStateForRegion and onBeaconServiceConnect is being called.

Can anyone please tell me what i am doing wrong or if some step is missing. I tried looking into other answers on stackoverflow, but this is the only library where i am seeing new classes and interfaces everywhere in all answers. Too much confusion.
P.S.
I am trying to make contact tracing app. Any other library or something you can suggest will also be appreciated.

Try reversing phones 1 and 2 for your tests. If you use BeaconScope to scan, can it see the transmissions of both phones 1&2? If you use BeaconScope to transmit, can your app on either phone 1 or 2 see the beacon tranamission?
If you cannot detect beacon scope on one or both phones, check app permissions to confirm that location permission has been granted to your app. Go to Settings -> Applications -> Your App and check the granted permissions.
Also check that location is enabled globally on the phone and that Bluetooth is on.

Kotlin Android Full Sized Camera instead of Thumbnail?

thanks for looking by! I've pretty much finished my little application i've been working on. I tried the app on my phone and found an error that I wasn't aware of when using the emulator (rookie mistake I suppose). So when the app is started the user can add like a "happy place" that looks the following:
the issue starts when the user wants to add a picture that he wants to take with the Camera itself. (That itself works). Taking the picture and also displaying it in that small box works (partly). But here is also my issue. After trying the app out on the phone i realised that the taken picture had terrible quality. I googled that issue and found out that i have used a method that only get's me the thumbnail on not the actual full sized picture. I googled more to find out how i can get that to work, unfortnunately i only found the documentation and i couldn't really figure it out either way what i had to change.
Here is my code that contains all info regarding the camera functionality:
