Why are you assuming that someone, somewhere has written the exact code you need to do exactly what you want and published it to the web?
Development is not about copy'n'paste code to solve every problem: someone has to write it to start with and to a greater or smaller part that will always be you! Library code is handy to help you do that, but it isn't going to do exactly what you want and will require changes and support code to get it to help you.

Hi
I am new to this area, I know that the RF Scanner Device is able to communicate with Warehouse Management System via connected wireless network.
Just to ask, is there any development guide line on this, such as:-
1. How RF Device Scan after, then transmit data to Warehouse Management System?
Hi, I would feel glad to be a membership of CodeProject, I know the site could help developer much

Check the Zebra website. they have API's and training for this sort of thing.
Intermec and Denso Wave have lots of resources.
Most apps seem to talk to a database at the backend. and are web app based. so as long as it fits the customers needs then i guess it would be ok.

Android studio. The program includes the ListView component. The ListView Item is populated via adapter from strings.xml. Each Item contains several words and one of them is a phone number. There is no problem filling in the Item. Need to do this when click (onclick) on a separate Item, program need to dial the number (call) that is specified inside the Item. How this can be done. Thanks.

Hello everyone,
First I'm new here once again hello all.
Actually my question is very simple and I'm new in android,
How to put loading message (whether text or progress bar) after user click on new activity,
I have 2 activity both are: MainActivity and DashboardActivity
Here's MainActivity code :
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
findViewById(R.id.textViewTest).setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
finish();
startActivity(new Intent(MainActivity.this, DashboardActivity.class));
}
});
}
}
DashboardActivity
public class DashboardActivity extends AppCompatActivity
{
private Toolbar mTopToolbar;
private AppBarConfiguration mAppBarConfiguration;
private NavigationView navigationView;
private int progressStatus = 0;
private Handler handler = new Handler();
private ProgressBar progressBar;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_drawer);
Toolbar toolbar = findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
getSupportActionBar().setDisplayShowTitleEnabled(false);
DrawerLayout drawer = findViewById(R.id.drawer_layout);
navigationView = findViewById(R.id.nav_view);
View hview = navigationView.getHeaderView(0);
mAppBarConfiguration = new AppBarConfiguration.Builder(
R.id.nav_home, R.id.nav_gallery, R.id.nav_slideshow)
.setOpenableLayout(drawer)
.build();
NavController navController = Navigation.findNavController(this, R.id.nav_host_fragment);
NavigationUI.setupActionBarWithNavController(this, navController, mAppBarConfiguration);
NavigationUI.setupWithNavController(navigationView, navController);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.main_menu, menu);
return true;
}
@Override
public boolean onSupportNavigateUp() {
NavController navController = Navigation.findNavController(this, R.id.nav_host_fragment);
return NavigationUI.navigateUp(navController, mAppBarConfiguration)
|| super.onSupportNavigateUp();
}
}
When I open dashboard activity it's show blank page approximately 4 - 5 sec before content loaded completely.
Q : My expectation is how to display loading text or progressbar when Dashboard activity blank / still loading?
please help
Thanks

Are you saying that it takes 4-5 seconds to go from one activity to another within the same app?

Yes, it because I used asynctask and cause frameskipping.
But thanks for reply

How does one hire an app programmer for an app that relies on ones location and the world map? Would it cost a lot? I am not interested in making money with the app. I just want to create an interesting interface.

Where does one even look for a good legit honest programmer? I don't know how to search.

Go to a local recruitment agency. It is really not that difficult.

I don't know what that is? What if the best person for the job isn't local?

'm learning Xamaring Forms. I want to test connecting to a Web API. I have a an Asp.Net Framework Web API running and I can connect to to it.
However, in my Xamarin Forms page, when I call it, the call to GetAsync never returns:
public class MainPageViewModel : _ViewModelBase
{
private string url = "<a href="https:
public List<TestDataEntity> Items { get; set; }
public MainPageViewModel()
{
GetData();
}
private async Task GetData()
{
try
{
HttpClient client = new HttpClient();
HttpResponseMessage response = await client.GetAsync(url);
if (response.IsSuccessStatusCode)
{
string content = await response.Content.ReadAsStringAsync();
Items = JsonConvert.DeserializeObject<List<TestDataEntity>>(content);
}
}
catch (Exception e)
{
throw;
}
}
}
I can paste the URL into a browser and see the JSON results. If the WebAPI is NOT running the GetAsync throws.
Anyone have any thoughts on this?
If it's not broken, fix it until it is.
Everything makes sense in someone's mind.
Ya can't fix stupid.

It sounds like you have a deadlock somewhere. Try adding .ConfigureAwait(false) to the GetAsync call.
private async Task GetData()
{
try
{
HttpClient client = new HttpClient();
HttpResponseMessage response = await client.GetAsync(url).ConfigureAwait(false);
if (response.IsSuccessStatusCode)
{
string content = await response.Content.ReadAsStringAsync();
Items = JsonConvert.DeserializeObject<List<TestDataEntity>>(content);
}
}
catch (Exception e)
{
throw;
}
}

Well that helped, a bit.
Again, I'm just trying to create a small, simple xamarin forms example that connects to a web api. I've read these:
Consume a RESTful Web Service - Xamarin | Microsoft Docs
6 Steps to Consume ASP.Net Core Web API in Xamarin | Syncfusion Blogs
Here's what I have now:
private async Task GetData()
{
string url = $"https://127.0.0.1:44340/api/Test/GetAll";
try
{
HttpClient client = new HttpClient();
HttpResponseMessage response = await client.GetAsync(url).ConfigureAwait(false);
if (response.IsSuccessStatusCode)
{
string content = await response.Content.ReadAsStringAsync();
Items = JsonConvert.DeserializeObject<List<TestDataEntity>>(content);
}
}
catch (Exception e)
{
throw;
}
}
My browser opens and shows the commented out url (https:/localhost:44340). Yet the call to GetAsync throws "{System.Net.WebException: Failed to connect to localhost/127.0.0.1:44340". When I try that URL I get the same exception.
If it's not broken, fix it until it is.
Everything makes sense in someone's mind.

Is the WebAPI project running? That looks like an IIS Express URL, which means you'll need to run the API project from Visual Studio for the URL to work.
Also, if you're using a self-signed certificate and you haven't added it to your local PC's trust store, you'll need some extra code to ignore the certificate error:
