org.json.JSONException: End of input at character 0 of : Dummy InputConnection bound,

What could be the reason why I am getting that kind of error? I have looked already for possible solutions for my problem, but I couldn't find one.
Here is the code:
//Method to show current record Current Selected Record

//Parsing the Stored JSOn String to GetHttpResponse Method.
new GetHttpResponse(ShowSingleRecordActivity.this).execute();
}

android update custom view in asynctask

Ok, I have a custom view which plays gifs from the internet. Therefor I need to add an url to my view to download the gif. But I can't seem to update my custom view inside my asynctask. I need to add an url string to my custom view gifView.setUrl(). It works in the onCreate Class but it gives me null in asynctask.
Oncreate class
GifView gifView;

Here is the Log from the url, it gives me null if I add the url inside my asynctask in Activity.
11-07 14:41:58.821 5674-6076/svenmobile.tools.showcase D/DEBUG﹕ URLnull
What I want to know is what the problem is and how to solve it if possible.
Thanks in advance, Sven

Maybe you called init() before setUrl().
You can pass it the url in the contructor, or public void init(final Context context, String urlStr)throws IOException{
I also suggest you to move all that network code to doInBackground

Using pagination for listview in android

How to integrate with jsonwebservices in Android?

I'm implementing json_web services in my Android application. I want to send the json data on jsonwebservices which is created in Java. When I run the application data does not send from the Android and does not show any error and also does not show any type of exception.
How can I identify whether my data is sent or not?

And you said i can't see the log message in doInbackground. i just ran your code and i can see the log

In Android: How can i send the result of from OnPostExecute() to other activity?

I got the result of OnPostExecute() to main activity but I want to use this result in second activity. I read and applied something with using Bundle but it doesn't run. I got error NullPointerException cause of not receiving the value in the second activity. Here is my MainActivity (It has an interface AsyncResponse ):
public class MainActivity extends Activity implements AsyncResponse
{
public String t;
public Bundle bnd;
public Intent intent;
public String sending;
private static final String TAG = "MyActivity";
ProductConnect asyncTask =new ProductConnect();
public void processFinish(String output){
sending=output;
}
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
asyncTask.delegate = this;
setContentView(R.layout.activity_main);
Button b = (Button) findViewById(R.id.button1);
bnd=new Bundle();
intent=new Intent(MainActivity.this, second.class);
b.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
asyncTask.execute(true);
bnd.putString("veri", sending);
intent.putExtras(bnd);
startActivity(intent);
}
});
}
// START DATABASE CONNECTION
class ProductConnect extends AsyncTask<Boolean, String, String> {
public AsyncResponse delegate=null;
private Activity activity;
public void MyAsyncTask(Activity activity) {
this.activity = activity;
}
#Override
protected String doInBackground(Boolean... params) {
String result = null;
StringBuilder sb = new StringBuilder();
try {
// http post
HttpClient httpclient = new DefaultHttpClient();
HttpGet httppost = new HttpGet(
"http://192.168.2.245/getProducts.php");
HttpResponse response = httpclient.execute(httppost);
if (response.getStatusLine().getStatusCode() != 200) {
Log.d("MyApp", "Server encountered an error");
}
BufferedReader reader = new BufferedReader(
new InputStreamReader(
response.getEntity().getContent(), "UTF8"));
sb = new StringBuilder();
sb.append(reader.readLine() + "\n");
String line = null;
while ((line = reader.readLine()) != null) {
sb.append(line + "\n");
}
result = sb.toString();
Log.d("test", result);
} catch (Exception e) {
Log.e("log_tag", "Error converting result " + e.toString());
}
return result;
}
#Override
protected void onPostExecute(String result) {
try {
JSONArray jArray = new JSONArray(result);
JSONObject json_data;
for (int i = 0; i < jArray.length(); i++) {
json_data = jArray.getJSONObject(i);
t = json_data.getString("name");

Here is My Second Activity:
public class second extends ActionBarActivity {
public CharSequence mTitle;
private static final String TAG = "MyActivity";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.second);
Bundle receive=getIntent().getExtras();
String get=receive.getString("veri");
Log.v(TAG, get);
}
What should i do?

AsyncTask.execute() is a non-blocking call. You can't set the result to the Bundle and start an Intent immediatly after execute(). That's why you are getting a NPE in your second Activity because sending isn't initialized, so it's null.
Move the code to start a new Activity with the desired data in your callback:
public void processFinish(String output){
bnd.putString("veri", output);
intent.putExtras(bnd);
startActivity(intent);
}
And make sure you call delegate.processFinished(String) if your data processing is finished. So move it out of the for loop. BTW t will only get the last "name"-String in the JSONArray. If you wanna get them all make t a String array and fill it.

As your variable t is globally declared in your activity so can directly use the value of t which you are assigning in your onPostExecute() method. Just you need to check for its null value only in your button click event as below :
b.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
asyncTask.execute(true);
if(t != null || t != "")
{
bnd.putString("veri", t);
intent.putExtras(bnd);
startActivity(intent);
}
}
});

// try this
public class MainActivity extends Activity
{
public String t;
public Bundle bnd;
public Intent intent;
private static final String TAG = "MyActivity";
ProductConnect asyncTask;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button b = (Button) findViewById(R.id.button1);
bnd=new Bundle();
intent=new Intent(MainActivity.this, second.class);
asyncTask = new ProductConnect(new ResultListener() {
#Override
public void onResultGet(String value) {
bnd.putString("veri", value);
intent.putExtras(bnd);
startActivity(intent);
}
});
b.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View arg0) {
asyncTask.execute(true);
}
});
}
class ProductConnect extends AsyncTask<Boolean, String, String> {
private ResultListener target;
public ProductConnect(ResultListener target) {
this.target = target;
}
#Override
protected String doInBackground(Boolean... params) {
String result = null;
StringBuilder sb = new StringBuilder();
try {
// http post
HttpClient httpclient = new DefaultHttpClient();
HttpGet httppost = new HttpGet(
"http://192.168.2.245/getProducts.php");
HttpResponse response = httpclient.execute(httppost);
if (response.getStatusLine().getStatusCode() != 200) {
Log.d("MyApp", "Server encountered an error");
}
BufferedReader reader = new BufferedReader(
new InputStreamReader(
response.getEntity().getContent(), "UTF8"));
sb = new StringBuilder();
sb.append(reader.readLine() + "\n");
String line = null;
while ((line = reader.readLine()) != null) {
sb.append(line + "\n");
}
result = sb.toString();
Log.d("test", result);
} catch (Exception e) {
Log.e("log_tag", "Error converting result " + e.toString());
}
return result;
}
#Override
protected void onPostExecute(String result) {
try {
JSONArray jArray = new JSONArray(result);
JSONObject json_data;
for (int i = 0; i < jArray.length(); i++) {
json_data = jArray.getJSONObject(i);
t = json_data.getString("name");
target.onResultGet(t);
}
} catch (JSONException e1) {
e1.printStackTrace();
} catch (ParseException e1) {
e1.printStackTrace();
}
super.onPostExecute(result);
}
protected void onPreExecute() {
super.onPreExecute();
ProgressDialog pd = new ProgressDialog(MainActivity.this);
pd.setTitle("Please wait");
pd.setMessage("Authenticating..");
pd.show();
}
}
interface ResultListener {
public void onResultGet(String value);
}
}

Shortly before someone posted a solution and it works without any errors but it was deleted. This solution is by this way:
public void onClick(View arg0) {
asyncTask.execute(true);
}
});
}
Then OnPostExecute changed like this:
protected void onPostExecute(String result) {
Intent passValue=new Intent(MainActivity.this, second.class);
try {
JSONArray jArray = new JSONArray(result);
JSONObject json_data;
for (int i = 0; i < jArray.length(); i++) {
json_data = jArray.getJSONObject(i);
t = json_data.getString("name");
delegate.processFinish(t);
}
passValue.putExtra("veri", t);
startActivity(passValue);
} catch (JSONException e1) {
e1.printStackTrace();
} catch (ParseException e1) {
e1.printStackTrace();
}
super.onPostExecute(result);
}
Lastly in my second activity receive the string by this way:
String receivedVal= getIntent().getExtras().getString("veri");
Log.v(TAG, receivedVal);
Thank you someone who posted this solution shortly before :)
