Show us the attempt you've made, via code, and you'll get more useful aid. As is stands, it looks like you just expect a solution.

Correct, but where is it defined?

What a delightful change of process between the two. Didn't realize that.

I think we'll need some additional code supplied. What does your validation look like, how is your form updated, etc, etc.

Google search showed several different solutions, as well as different possibilities for cause. With information here being limited, have you tried solutions from Googly?

Oh yes, Eclipse has some debugging options. It's vital to learn how to use it, especially if you are a professional, or are pursuing this stuff professionally. I use Visual Studio's debugger daily. I found some info on eclipse's debugger. https://www.eclipse.org/community/eclipse_newsletter/2017/june/article1.php

What are you using to code in Java?

Without knowing how the entire project functions, my insight is limited. The debugger would be useful here. Run through and see if the values are what you expect at each point, and go from there.

Why would you want to put all of that info into main only, and then recursively call main()? Splitting into methods is precisely the way I would do it. It makes things more manageable.
If you're referring to taking the separate classes and joining into a single, then that is possible.

I'm not sure of differences in local, but during development with django, our API requests had to be authenticated, and permissions were bound to accounts. General users could post/get, but only admins had access to delete/put. Some resource on that server should be managing that, because you would not want delete/put exposed to and usable by everyone.
The error is mentioning it's a permission issue, so I would investigate how those are handled.

and the token is bound to an account type, correct? i.e. general user

When your app contacts the server, how does the server resolve who is making the request?

Your PUT command is creating a brand new resource; a new customer. From an operation standpoint, put and post are not the same.
Two of the API's I use daily allow me to post information, but I am not permitted to send those same requests with a 'put' command; I don't have permission.

There's no new packages to grab, and the verbage change from POST to PUT is usually the requirement, but I seem to recall that (in the little bit of web dev I did in college) that the account making the request had to have explicit permissions.

Doesn't each type of request require the respective permission to do so? Have you verified that you have the permission to PUT?

for (int i = 0; i < listView.getAdapter().getCount(); i++) {
if (listView.getChildAt(i) != null) {}
The second line is checking if the listview has children (for that iteration.)
My point 2) is asking if you have verified that
if(listView.getChildAt(i) != null) {}
is in fact not null for all 15 iterations of the loop.

Have you:
1) Verified the listView.getAdapter().getCount(); is returning the correct value (of 15)?
2) If 1 is correct, that all listView items have children?

Is there an issue, or it this a dump-in-someone-else's-lap sort of deal?

Were there any errors or status notifications when you ran the migrate?

Just for clarity, is this an additional page being added to a site that is already live (and working otherwise?)

Have you checked that the permission to access the user's location is being set properly? I recall a similar issue when I did geoservice stuff.

Why is there a need for this duplicate question, when you have aid in the original?

I hadn't considered that. I appreciate your addition, good sir.

Where is $res fetching an array from? Does fetch take a param?

I personally am not familiar with MIPS syntax, but the first slide here might be useful. https://courses.cs.vt.edu/cs2506/Fall2014/Notes/L04.MIPSAssemblyOverview.pdf

You can check to make sure data is within the 0-99 bounds before checking the success/failed.

This smells like homework. Have you attempted the problem, so that one might offer some guidance, over just the solution?

Beat me to it. Take my stars...

Does the column "CarNumber" exist in the DB?

From the code provided above, conString is not declared, meaning the new OracleConnection(conString) will not process, because it is null. The connection will never be opened to the DB.

Is the adView.AdUnitId assignment intentional? The number looks fake and does not match what Google provides here https://developers.google.com/admob/android/banner
From what I could gather, the adLoad() should be called in the class that is going to make the request, and not in the renderer itself, but my experience with how Xamarin does things vs Android Studio, is limited.

By "crashing", do you mean at apk install or during runtime? If you have access to real hardware, Android Studio supports live debugging on the device (you might already know.) I used that feature quite a lot for troubleshooting, instead of those... delightful emulators.

It's odd that the question is near identical to the first time, but maybe the solution I offered previously wasn't enough. I figured mentioning Jon's answer specifically, and trying to show it does (I think) what the OP is looking for, was the best option here.

The question is vague and doesn't have a simple answer. What type of data, and what are you doing with it? Is there a language or framework in mind? There are plenty of resources/tutorials on MVC on Google, so I would start there.
