Without more details (like seeing some code).

1) Do not block the UI thread, this can cause a `SIGABRT` as the OS will kill a non-responsive app.

&gt; bind and unbind on every activity when i switch for like 11 times it crashes my app

2)  Make sure that in your `OnDestroy` within your `Activity` you are cleaning up after yourself. i.e. Removing all your `Listeners`/`Events` and then calling the `Base.OnDestory`. 

3) An external (i.e. `BluetoothLeService`) service calling back into your app with listeners that now null/nil will cause hangs and thus a `SIGABRT`, see #2






According to Wikipedia:

&gt; The SIGABRT signal is sent to a process to tell it to abort, i.e. to terminate. The signal is usually initiated by the process itself when it calls abort function of the C Standard Library, but it can be sent to the process from outside like any other signal

It usually indicates some kind of error in your code or one of the libraries that you call.

I&#39;ve started learning React / Redux and stumbled on something that is probably a very basic question. Below are snippets from my app with some code removed for simplicity sake.

My state is described by an array of sites which is empty by default. Later reducer will have `LOAD_SITES` action to load a different set of sites whenever user paginates to a different page but for now it&#39;s doing nothing. React starts by rendering `PublishedSitesPage` which then renders `PublishedSitesBox` which then loops over data and renders individual sites. 

What I want to do is have it render everything with the default empty array and meanwhile initiate a &quot;load sites from server&quot; promise and once it resolves, dispatch `LOAD_SITES` action. What is the best way to make this call? I was thinking about either constructor of `PublishedSitesBox` or perhaps `componentDidMount`. But not sure if this would work - my concern is that I&#39;ll create an endless loop this way that will keep re-rendering. I guess I could prevent this endless loop in some way by having some other state param along the lines of &quot;haveRequestedInitialData&quot;. Another idea I had is to simply make this promise right after doing `ReactDOM.render()`. What is the best and cleanest way to do this?

    export default function sites(state = [], action) {
      switch (action.type) {
        default:
          return state;
      }
    }
    ...
    
    const publishedSitesPageReducer = combineReducers({
      sites
    });
    
    ReactDOM.render(
      &lt;Provider store={createStore(publishedSitesPageReducer)}&gt;
        &lt;PublishedSitesPage /&gt;
      &lt;/Provider&gt;,
      this.$view.find(&#39;.js-published-sites-result-target&#39;)[0]
    );
    
    ...
    
    export default function PublishedSitesPage() {
      return (
        &lt;PublishedSitesBox/&gt;
      );
    }
    
    ...
    
    function mapStateToProps(state) {
      return { sites: state.sites };
    }
    
    const PublishedSitesBox = connect(mapStateToProps)(({sites}) =&gt; {
      // render sites
    });

Where do I fetch initial data from server in a React Redux app?

I am using a query parameters to set the values needed by the Google Maps API.

The issue is I do not need the `&amp;` sign for the first query parameter.

    @GET(&quot;/maps/api/geocode/json?&quot;)
        Call&lt;JsonObject&gt; getLocationInfo(@Query(&quot;address&quot;) String zipCode,
                                                 @Query(&quot;sensor&quot;) boolean sensor,
                                                 @Query(&quot;client&quot;) String client,
                                                 @Query(&quot;signature&quot;) String signature);

Retrofit generates: 

    &amp;address=90210&amp;sensor=false&amp;client=gme-client&amp;signature=signkey

which causes the call the fail when I need it to be

    address=90210&amp;sensor=false&amp;client=gme-client&amp;signature=signkey

How do I fix this?

How to I print information from a map that has the object as the value?

I have created the following map:

    Map&lt;String, Object&gt; objectSet = new HashMap&lt;&gt;();

The object has its own class with its own instance variables

I have already populated the above map with data. 

I have created a `printMap` method, but I can only seem to print the Keys of the map

How to do I get the map to print the `&lt;Object&gt;` values using a for each loop?

So far, I&#39;ve got:

    for (String keys : objectSet.keySet())
    {
       System.out.println(keys);
    }


The above prints out the keys. I want to be able to print out the object variables too.

I am going through this book on restful web services with spring. I decided to move away from what they were doing and use java configuration files. For some reason, after switching over to the Java configuration, the service would run (in the console window) correctly but when I actually go to the endpoint on localhost i get this:

&gt; White label Error Page
&gt; 
&gt; This application has no explicit mapping for /error, so you are seeing
&gt; this as a fallback.
&gt; 
&gt; Sat Apr 23 20:48:25 PDT 2016 There was an unexpected error (type=Not
&gt; Found, status=404). No message available

And this is the response from the GET request:

    {
        &quot;timestamp&quot;: 1461470029110,
        &quot;status&quot;: 404,
        &quot;error&quot;: &quot;Not Found&quot;,
        &quot;message&quot;: &quot;No message available&quot;,
        &quot;path&quot;: &quot;/greeting&quot;
    }

The next chapter of this story begins with me going to the getting started page on the Spring website http://spring.io/guides/gs/rest-service/ I decided to start a small project recreating their basic tutorial. I will post the code I wrote below for you to see. The problem is, I am having the exact same issue. The service runs but I can&#39;t hit the endpoints. I am not sure what is going on and I have seen others with similar issues, but the answers have not applied/helped with mine. I am sure it is something obvious that I am doing wrong and any help would be greatly appreciated. One last piece of information, if at all relevant, I am using IntelliJ IDEA 15 CE as my IDE.

Issue With Spring: There was an unexpected error (type=Not Found, status=404)

I came across a new term in Java 8: &quot;functional interface&quot;. I could only find one use of it while working with *lambda expressions*. 

Java 8 provides some built-in functional interfaces and if we want to define any functional interface then we can make use of the `@FunctionalInterface` annotation. It will allow us to declare only a single method in the interface.

For example:

    @FunctionalInterface
    interface MathOperation {
        int operation(int a, int b);
    }

How useful it is in Java 8 other than just working with *lambda expressions*? 

(The question [here][1] is different from the one I asked. It is asking why we need functional interfaces while working with lambda expressions. My question is: What are the other uses of functional interfaces besides use with lambda expressions?)

        //Variance checking and logging of changes between the modified and original
    }

This is where I am calling this method from:

    public IActionResult Update(DetailViewModel vm)
    {
        var originalClient = (Client)_service.GetAsNoTracking(vm.ClientId);
        var modifiedClient = (Client)_service.Fetch(vm.ClientId.ToString());
        // Changing the modifiedClient here
        _service.Update(originalClient, modifiedClient);
    }

Here is the `GetAsNotTracking` method:

    public Client GetAsNoTracking(long id)
    {
        return GetClientQueryableObject(id).AsNoTracking().FirstOrDefault();
    }

`Fetch` method:

    public object Fetch(string id)
    {
       long fetchId;
       long.TryParse(id, out fetchId);
       return GetClientQueryableObject(fetchId).FirstOrDefault();
    }

`GetClientQueryableObject`:

    private Microsoft.Data.Entity.Query.IIncludableQueryable&lt;Client, ActivityType&gt; GetClientQueryableObject(long searchId)
    {
        return _context.Clients
            .Where(x =&gt; x.Id == searchId)
            .Include(x =&gt; x.Opportunities)
            .ThenInclude(x =&gt; x.BusinessUnit)
            .Include(x =&gt; x.Opportunities)
            .ThenInclude(x =&gt; x.Probability)
            .Include(x =&gt; x.Industry)
            .Include(x =&gt; x.Activities)
            .ThenInclude(x =&gt; x.User)
            .Include(x =&gt; x.Activities)
            .ThenInclude(x =&gt; x.ActivityType);
     }

Any ideas?


I have looked the following articles / discussions. To no avail:[ASP.NET GitHub Issue 3839][1]

**UPDATE:**

Here are the changes to `GetAsNoTracking`:

    public Client GetAsNoTracking(long id)
    {
        return GetClientQueryableObjectAsNoTracking(id).FirstOrDefault();
    }

`GetClientQueryableObjectAsNoTracking`:

    private IQueryable&lt;Client&gt; GetClientQueryableObjectAsNoTracking(long searchId)
    {
        return _context.Clients
            .Where(x =&gt; x.Id == searchId)
            .Include(x =&gt; x.Opportunities)
            .ThenInclude(x =&gt; x.BusinessUnit)
            .AsNoTracking()
            .Include(x =&gt; x.Opportunities)
            .ThenInclude(x =&gt; x.Probability)
            .AsNoTracking()
            .Include(x =&gt; x.Industry)
            .AsNoTracking()
            .Include(x =&gt; x.Activities)
            .ThenInclude(x =&gt; x.User)
            .AsNoTracking()
            .Include(x =&gt; x.Activities)
            .ThenInclude(x =&gt; x.ActivityType)
            .AsNoTracking();
    }

The instance of entity type cannot be tracked because another instance of this type with the same key is already being tracked

I&#39;m facing a problem with the new backward compatibility with VectorDrawables.
In the Support Library 23.2 was a new feature for backward compatibility with Android VectorDrawables indroduced. 

I have an ImageView which is a SelectorDrawable assigned to. This Drawable holds several VectorDrawables so I thought I should use app:srcCompat for compatibility. But it does not work on my Galaxy S2 with android 4.1.2.

    &lt;?xml version=&quot;1.0&quot; encoding=&quot;utf-8&quot;?&gt;
    &lt;selector xmlns:android=&quot;http://schemas.android.com/apk/res/android&quot;&gt;
        &lt;item android:drawable=&quot;@drawable/ic_gps_fixed_24dp&quot;android:state_activated=&quot;true&quot; android:state_selected=&quot;true&quot;&gt;&lt;/item&gt;
        &lt;item android:drawable=&quot;@drawable/ic_gps_not_fixed_24dp&quot; android:state_activated=&quot;true&quot; android:state_selected=&quot;false&quot;&gt;&lt;/item&gt;
        &lt;item android:drawable=&quot;@drawable/ic_gps_not_fixed_24dp&quot; android:state_activated=&quot;false&quot; android:state_selected=&quot;true&quot;&gt;&lt;/item&gt;
        &lt;item android:drawable=&quot;@drawable/ic_gps_off_24dp&quot; android:state_activated=&quot;false&quot; android:state_selected=&quot;false&quot;&gt;&lt;/item&gt;
        &lt;item android:drawable=&quot;@drawable/ic_gps_not_fixed_24dp&quot;&gt;&lt;/item&gt;
    &lt;/selector&gt;

All drawables are vector xml files.

When using this SelectorDrawable with srcCompat I get this error:

      Caused by: android.content.res.Resources$NotFoundException: File res/drawable/  Caused by: android.content.res.Resources$NotFoundException: File res/drawable/ic_gps_fixed_24dp.xml from drawable resource ID #0x7f0201c1
                                                                               at android.content.res.Resources.loadDrawable(Resources.java:1951)
                                                                               at android.content.res.Resources.getDrawable(Resources.java:672)
                                                                               at android.graphics.drawable.StateListDrawable.inflate(StateListDrawable.java:173)
                                                                               at android.graphics.drawable.Drawable.createFromXmlInner(Drawable.java:881).xml from drawable resource ID #0x7f0201c1
                                                                                  

using android:src is even worse.

If I use one of the vector drawables with app:srcCompat all works fine. So I guess it&#39;s a problem with the SelectorDrawable and compatibility.

Has anyone had the same problem and found a solution or is it currently not possible to use VectorDrawables in SelectorDrawables prior to Android 5?

The Quick Facts:

 - Compile Target API 23 
 - Support Libraray 23.3.0
 - vectorDrawables.useSupportLibrary = true 
 - Gradle 2.0

On my Samsung Galaxy tab 4 (Android 4.4.2, Chrome: 49.0.2623.105) I ran into a situation where the keyCode is always 229. 

I&#39;ve setup a simple test for two situation

    &lt;div contenteditable=&quot;true&quot;&gt;&lt;/div&gt;
    &lt;input&gt;
    &lt;span id=&quot;keycode&quot;&gt;&lt;/span&gt;

script:

    $(&#39;div, input&#39;).on(&#39;keydown&#39;, function (e) {
        $(&#39;#keycode&#39;).html(e.keyCode);
    });
    

[DEMO][1]

Fortunately I can find posts about this, but I couldn&#39;t find one with a working solution. Someone suggested to use `keyup` instead or to use the `textInput` event, but that one is only fired on `blur`.

Now, to top it all, this doesn&#39;t happen with the default stock browser :(

Any help would be appreciated!

UPDATE: If it turns out that this is not possible I can still grab the char before the caret: [post][2]

Microsoft now has .NET Core, .NET Framework and Xamarin (Mono) in its family.

It seems to be a lot of overlap here. What&#39;s the difference between these types of .NET Platforms? When should I choose to use .NET Core in my project, instead of .NET Framework or Xamarin? 

What&#39;s the difference between .NET Core, .NET Framework, and Xamarin?

The following `MarkerClick` implementation works, perfectly fine. I could be able to open other Views via `ShowViewModel`

**View.cs**

    mMap.MarkerClick += MMap_MarkerClick;
   
    private void MMap_MarkerClick(object sender, GoogleMap.MarkerClickEventArgs e)
    {
       ViewModel.MapInfoSelected(e.Marker.Title);
    }

**ViewModel.cs**

    public void MapInfoSelected(string name)
    {
        ShowViewModel&lt;StudentViewModel&gt;(new { studentName = name});
    }

-------------------------------------

`InfoWindowClick` does not trigger to open other View.

**View.cs**

    mMap.InfoWindowClick += MMap_InfoWindowClick;

    private void MMap_InfoWindowClick(object sender, GoogleMap.InfoWindowClickEventArgs e)
    {
      ViewModel.MapInfoSelected(e.Marker.Title);
    }

**ViewModel.cs**

    public void MapInfoSelected(string name)
    {
     // it hits here, but does not hit `StudentViewModel` Init() method, the app is frozen and do nothing
        ShowViewModel&lt;StudentViewModel&gt;(new { studentName = name});
    }

I even tried the `SetOnInfoWindowClickListener` as follows, it also does not open the View. 

     mMap.SetOnInfoWindowClickListener(this);

     public void OnInfoWindowClick(Marker marker)
     {
         ViewModel.MapInfoSelected(marker.Title);
     }

**UPDATE:**

It even hits the `OnPause()` method, but still it does not call `StudentViewModel` Init() method if I use `InfoWindowClick` event

     public override void OnPause()
     {
       base.OnPause();
       mMap.InfoWindowClick -= MMap_InfoWindowClick;
     }

MarkerClick works but InfoWindowClick does not open ViewModel
