Re: App crash always. Why?

31-Jan-16 7:37

My app crashes always when displaying listview with youtube thumbnail. I've created this app with AsyncTask,in doInBackground i'm fetching youtube video id and title which is in json... Then in onPostExecute i'm inflating my youtube view layout with customadapter and adding thumbnail for each list items in listview. But my app crashes always when doing this process... I used this listview with youtube thumbnail without getting title and video id from json(I did normal string array of title and video id,so there is no problem with my custom adapter.it works fine)I heard that if an app delay to get views for 5 secs,it'll automatically crashes... Is it true ? and Please help me what to do for this issue.. I'm new to Android...

An application crashes when the code you wrote is wrong...However we can not say what wrong with it if we can't see it...

MainActivity

Java

protected void onPostExecute(Integer result){
          //  Toast.makeText(getApplicationContext(),"onPostExecute",Toast.LENGTH_SHORT).show();
            if(result == 1){
                Toast.makeText(getApplicationContext(),"Result = 1",Toast.LENGTH_SHORT).show();

                CustomAdapter customAdapter = new CustomAdapter(context,Title,VideoID);


               listView.setAdapter(arrayAdapter);

CustomAdapter

Java

 public CustomAdapter(Activity context,String[] Title,String[] VideoID){

        super(context,R.layout.activity_main,VideoID);
        this.context = context;
        this.Title = Title;

        View ListItemView = convertView;

        if (convertView == null){

            LayoutInflater inflater = context.getLayoutInflater();
            ListItemView = inflater.inflate(R.layout.youtubethumbnail_loader,null,false);    //Inflating youtube thumbnail view layout


        }


       youTubeThumbnailView = (YouTubeThumbnailView)ListItemView.findViewById(R.id.youtubethumbnailviewnew);
        youTubeThumbnailView.initialize(Config.API_KEY, new YouTubeThumbnailView.OnInitializedListener() {


            @Override

                Toast.makeText(context,"Success initialization",Toast.LENGTH_SHORT).show();
                youTubeThumbnailLoader = thumbnailLoader;

                thumbnailLoader.setOnThumbnailLoadedListener(new YouTubeThumbnailLoader.OnThumbnailLoadedListener() {
                    @Override
                    public void onThumbnailLoaded(YouTubeThumbnailView youTubeThumbnailView, String s) {


                        Toast.makeText(context, "Welcome to ShortFilmy", Toast.LENGTH_SHORT).show();

                    }

                    @Override
                    public void onThumbnailError(YouTubeThumbnailView youTubeThumbnailView, YouTubeThumbnailLoader.ErrorReason errorReason) {

                    }
                });

                thumbnailLoader.setVideo(VideoID[position]);  //setting video id to getting thumbnail

            }

            }
        });

        textView = (TextView)ListItemView.findViewById(R.id.textViewnew);
        textView.setText(Title[position]);

        return ListItemView;
    }

}

Here,my customadapter is working fine when i used without asynctask but if I call customadapter class in asynctask(onPostExecute method) it'll force close my app. I googled a lot about this but i didn't know what to do for this.. But I heard that every app wants to view the widgets or anything within 5 secs in UI thread otherwise our app got crashed.So you guys wanna help me out...

How to inflate the youtubethumbnailview ?

Did you try some debugging of your application? You need to identify where the crash occurred and what were the circumstances at the time. Only then will you be able to start figuring out why it crashed.

Typically, you inflate entire XML file for that view. I have never used this, but I think it would be used in a layout (RelativeLayout or LinearLayout), just like any other control.

From the following blog, the code would be something like this:

XML

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    android:orientation="vertical"
    tools:context=".MainActivity"> 
    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/hello_world" />
    <com.google.android.youtube.player.YouTubeThumbnailView
        android:id="@+id/thumbnailview"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />

</LinearLayout>

Then, you can inflate it using any LayoutInflater object, get it using getLayoutInflater().

i'am trying to send string to webservice and get replay from.

i use android studio for programming on java for android

and visual-studio 2010 for programming the C# webservice.

i have this code on android

private static final String SOAP_ACTION = "http://tempuri.org/HELO";

private static final String OPERATION_NAME = "HELO";// your webservice web method name

private static final String WSDL_TARGET_NAMESPACE = "<a href="http://tempuri.org/">http://tempuri.org/</a>";

private static final String SOAP_ADDRESS = "<a href="http://10.0.0.2/WS_TEST/Service1.asmx">http://10.0.0.2/WS_TEST/Service1.asmx</a>";

        SoapObject request = new SoapObject(WSDL_TARGET_NAMESPACE, OPERATION_NAME);
        PropertyInfo info= new PropertyInfo();
        info = new PropertyInfo();
        //Set Name
        info.setName("HELO");
        //Set Value
        info.setValue("New User");
        //Set dataType
        info.setType(String.class);
        //Add the property to request object
        request.addProperty(info);

        SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
        envelope.dotNet = true;

        envelope.setOutputSoapObject(request);
        HttpTransportSE httpTransport = new HttpTransportSE(SOAP_ADDRESS);
        try {
            httpTransport.call(SOAP_ACTION, envelope);
            Object response = envelope.getResponse();
            tvData1.setText(response.toString());
        } catch (Exception exception) {
            tvData1.setText(exception.toString());
        }

and this my C# WebService

[WebService(Namespace = "<a href="http://tempuri.org/">http://tempuri.org/</a>")]
   [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
   [System.ComponentModel.ToolboxItem(false)]
   // To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line.
   // [System.Web.Script.Services.ScriptService]
   public class Service1 : System.Web.Services.WebService
   {

       [WebMethod]
       public string HELO(string Name)
       {
           return "Hello : " + Name;
       }

   }

and i got only Helo: without the string that i send instead of Helo: New User

I would suggest debugging to see if WCF is capturing the value being passed or not. It may be caused by the value not being passed to the function, or value being empty string or something.

You want to know WHO can use it? That seems an odd question.

Anyway, have you stepped through the code line by line using the debugger to see what is going on? What is the value of des? Of query?

the value is get intent form first activity

So the value of query is "get intent form first activity"? Well no wonder your code does not work; That is not a valid SELECT statement! Roll eyes | :rolleyes:

What's the difference between creating objects

Code 1:

Java

ArrayList<String> arraylist = new ArrayList<String>();

and

Java

List<String> arraylist = new ArrayList<String>();

Then what is this

Java

List<Map<String,String>> countryList = new ArrayList<Map<String,String>>();

Why we're using Map inside this ? Please anyone help me to understand... I'm learning json parsing in android.

I know about arraylist and maps.. Explain me clearly please.... Thanks in advanced Smile | :)

It is an array of Maps, but with so little context it is difficult to know its purpose. Maybe you should ask the person who wrote the code.
