PLEASE HELP ME!!

this is my take, if you buy a phone off of ebay or craig's list or even a website, i would not pay any money until the phone has been inspected by you. in fact i always suggest that the deal be done in person and at the carrier you plan to sign the phone up with. this way you can verify with the carrier that the phone is legit and not blacklisted as well as getting the phone registered with them. after that then you can pay the man, as they say.
Absolutely agree with you!

Apps Architectural question: Android Studio Navigation Drawer template project files

My question is an architectural question about Android Studio's Navigation Drawer template project files.
I am teaching myself to use Android for an app for my final year BSc computing project with the Open University (UK).

1) Why does the Navigation Drawer template project include both ViewModel java files for each of the Fragments as well as fragment java files?

I'm trying to understand if this is the way Fragments are usually structured with a separate java file for the actual content of a Fragment screen. If this is the case, what would I put in the Fragment java file rather than the ViewModel java file?

2) The template also provides a second home Fragment, I'm really not sure why? Any explanation for that? (I don't think I need this...)

3) As I'm completely new to Android Fragments (I think I understand how to work with just Activities), could someone please explain the role of the single Activity in the the Navigation Drawer template project?

I understand that you need an Activity to underpin the Fragments. Does the Activity actually need to be one of the visible screen like the home screen (as it would be in an app without Fragments) or is it just there behind the scenes providing the functionality for the Fragments according to what java code I put in the Fragments and Activity java files?

These things are puzzling me.

So far I have adapted the Navigation Drawer template so that there is just the one MainActivity.java file with 5 Fragments, each with a unique Fragment.java and ViewModel.java file and a layout.xml file per Fragment. The home screen is one of the Fragments and the Activity is not visible. Is this a good structure?

Any explanations or feedback would be very gratefully received, thanks from purplebeans!

Galaxy M20 BOOTLOOP! Can you help me?

It just seems like your previous flashed firmware was on a highr aboot and now that your trying to flash the correct firmware for your device it could be on a lower aboot (fused).

Count 5 digits from the end of the first firmware you flashed (the incorrect firmware)

for instance my Note 4 previous firmware was

N910PVPS4DPK1 and fused (aboot) 4

uodated firmware

N910PVPU5DQ15 and fused (aboot) 5

Since I am now on fused 5, I am unable to downgrade bootloader and modem. Trying to will result in Odin fail.

Also try another version of Odin

Help Texting app

Hello,
I have a question about my Galaxy Tab S6 and Galaxy S20. Is there a way that I can see my text on both devices?
I use Verizon texting app on both deivces don't get the messages on both devices. I only get the text on my phone. Even if I start a text on my tablet, I still don't get any gifs, text, response nothing. I am signed into both of them with the same user name and phone number.
Or is there an app that I can download and use across both devices, that will sync across both of them, so if I don't have phone near me, I can still get the text on tablet and vice versa..

Thank you in advance

Import Project Android Studio

I have an assignment to do for Coursera (Java for Android) and I'm getting some errors when I import an unzipped file (week 1 programming assignment) into the SDK. I extracted the zipped file into a folder named "Geometry Calculations." When the SDK prompts me for a file name, I select that folder for import. Seems like it would pretty simple. I get the following errors:

Project Import Warning
project file should not contain whitespace, as this can cause problems with the NDK tools.

Geometry Caclulations: failed at 4/23/2020 6:33 PM with 1 error
java.lang.IllegalStateException: failed to find target with hash string 'android-22' in: C:\Users\Mark\AppData\Local\Android\Sdk
ERROR: failed to find targert with hash string 'android-22' in: C:\Users\Mark\AppData\Local\Android\Sdk

This is from the the assignment specs:

Resources:

Please download the supplied zip file available with this specification. Extract the files onto your computer. The extracted files contain an Android Studio project. Start Android Studio and import the project as demonstrated in an earlier module. All your work for this assignment will be in the file Logic.java. Open this file in the IDE and look for the comment:

// TODO -- add your code here

As you do your work, be sure to place all your code in the Logic class.

The demonstration of the import procedure was not detailed enough for me. I would appreciate some clarification. Thanks!

Why can't I find these 2 popular apps?

Also, do not always trust the Play Store to be honest about apps they claim are 'incompatable'.

I discovered that an app I am fond of was deemed incompatible for my new device by Google.

After mutiple fruitless encounters with both Google and the developers of the app, I went to a different app store, UpToDown, where I easily downloaded and installed the app.

I also discovered ApkPure, where the app I wanted also can be downloaded and used perfectly on my 'incompatible' device.

Also, there are many, many exellent apps that are not on Google.

Sure, an upgrade in device may be nice, but so is broadening your horizons.
As is increasing your options.

Debating the switch to Android

Android has, unfortunately, been "late to the party" with a lot of vehicle implementations. For example, the Toyota RAV4, the single best selling vehicle in the U.S. didn't adopt Android Auto until the 2020 model year. :( I would guess you are struggling with outdated technology in your vehicles.

As far as the permission thing goes, it sounds like you are connecting the device as storage and not a media player every time you plug it in. That's why it asks for permission and has to refresh the media lists. What app are you using to playback media?

MP3's/WMA's with artwork in file folder -artwork doesn't show on my phone

How are you transferring your music files to your S20 Plus? Things like embedded artwork and text are directly tied to each file's metadata (file format type isn't the issue to focus on). Every time you're transferring files between your phone and your computer, you may only see the sanitized GUI actions but in the background there's an involved compatibility issue as different operating systems rely upon different file systems to store their files/folders -- your phone uses ext4 as its file system, a microSD card will default to either Microsoft's FAT32 or exFAT, and you WinPC will most likely be using NTFS. All three store metadata differently (with FAT32/exFAT being the most deficient) so depending on just how you did the file transfers and just which media player apps you're using, along with if your audio files are being stored on the internal storage or microSD card, all those variables will be a factor in how the metadata is or isn't retained.

Nokia 3.1 Plus unlocking

ok just to be clear, this is a prepaid phone, correct? not sure how you can carrier unlock the phone that is prepaid. that is something that usually is done by your carrier. there are plenty of services online, but you will have to pay for it.

well thank you for your support. It is a cricket prepaid. I'll see who else can help me out on this one. Cause if your right I just wasted almost about 200$
