I need to concat the received value to the print variable.
But this the error which i receive
print needs to be initialized is what I receive.
also if declared outside the try/catch block it requires it to be final.
What to do?
just use String print = null; when you declare print
You are providing a value that is not initialized to the String.format
You need to initialize the variable "print" with what you want to be used in the String.format (for example an empty String) :
String print= ""
Or use String Builder:
StringBuilder stringBuilder = new StringBuilder();
stringBuilder.append("1");
stringBuilder.append("2");
String finalString = stringBuilder.toString();

I having a problem update the Item in Recycler View.I will explain clearly about my problem.
I am using two Json URL's first Json URL can send the items to model class.
after completed this called the adapter, then update the second Json URL items with the adapter by using setter model class.
so that's why called adapter.notifyitemchanged, but only one time can updated items next time while looping doesn't update the items display empty for second time.

Anyone solve this problem glad to appreciate.
Thanks in advance
The problem is volley doesn't wait for the request to be completed. So as the first call is made within seconds other call will be also made. So, you need to create an interface which will be called when the first webservice is called, and than in interface call other webservice and than notifyDataSet.

I am trying to make a web service call via android button click. I've managed to rectify the errors, but it shows some bugs on getting response. I receive null response. Below is my code. Could someone debug me please..!
My code:
refresh_btn.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
HttpHandler httpHandler1 = new HttpHandler();
String res = null;
String authToken = "MlSyULrWlFgVk28";
try {
Log.d("edwLog", TAG + " get_payment_notifications " + HttpHandler.API_URL + "get_payment_notifications/" + authToken + "/");
res = httpHandler1.makeServiceCall(HttpHandler.API_URL + "get_payment_notifications/" + authToken + "/", HttpHandler.GET);
Log.d("edwLog", TAG + " response > " + res);
if (res != null) {
JSONObject jsonObject = new JSONObject(res);
String responseType = jsonObject.getString("type");
if (responseType.equals("success")) {
if (jsonObject.has("response")) {
JSONArray jsonArray = jsonObject.getJSONArray("response");
for (int i = 0; i < jsonArray.length(); i++) {
notifications.add(jsonArray.getJSONObject(i));
}
}
}
}
} catch (Exception e) {
e.printStackTrace();
Log.d("edwLog", TAG + " IOException > " + e.toString());
}
}
});
Are you getting compile time error or runtime. It seems that you are trying to return a bundle from a method that has a return type void i.e.
public void onClick(View v)
Found the bug..! The mistake was, I had passed the AuthToken as a default String. Now I declared it as "null" in final, i.e., before onCreate and deleted it from inside the ClickEvent. And its done.. The right code below..
refresh_btn.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
HttpHandler httpHandler1 = new HttpHandler();
String res = null;
try {
Log.d("edwLog", TAG + " get_payment_notifications " + HttpHandler.API_URL + "get_payment_notifications/" + AuthToken + "/");
res = httpHandler1.makeServiceCall(HttpHandler.API_URL + "get_payment_notifications/" + AuthToken + "/", HttpHandler.GET);
Log.d("edwLog", TAG + " response > " + res);
if (res != null) {
JSONObject jsonObject = new JSONObject(res);
String responseType = jsonObject.getString("type");
if (responseType.equals("success")) {
if (jsonObject.has("response")) {
JSONArray jsonArray = jsonObject.getJSONArray("response");
for (int i = 0; i < jsonArray.length(); i++) {
notifications.add(jsonArray.getJSONObject(i));
}
}
}
}
} catch (Exception e) {
e.printStackTrace();
Log.d("edwLog", TAG + " IOException > " + e.toString());
}
}

I have been working with GSON to try and parse a Json response I am getting from a CakePHP server for about a week. Here is what the response looks like :
[{"BaseObject": {"field1":"1","field2":"1639","field3":"10","field4":"1","field5":"12","field6":"10.765984","field7":"-25.768357","field8":"1327790850"}},{"BaseObject":{"field1":"2","field2":"1934","field3":"19","field4":"30","field5":"2","field6":"10.758662","field7":"-25.769684","field8":"1327790850"}},{"BaseObject":{"field1":"3","field2":"2567","field3":"33","field4":"6","field5":"98","field6":"10.758786","field7":"-25.769843","field8":"1327790850"}},{"BaseObject":{"field1":"4","field2":"0","field3":"33","field4":"7","field5":"0","field6":"10.758786","field7":"-20.769843","field8":"1327790850"}},{"BaseObject":{"field1":"5","field2":"1097","field3":"33","field4":"1","field5":"0","field6":"15.758786","field7":"50.769843","field8":"1327790850"}},{"BaseObject":{"field1":"6","field2":"1936","field3":"50","field4":"0","field5":"9","field6":"19.234987","field7":"-67.340065","field8":"1327798560"}}]
I used a plugin for Notepad++ to verify that the response is valid Json and it is.
First I tried this function:
public static List<BaseObject> parserInputStreamGson(InputStream stream)
{
List<BaseObject> objList = new ArrayList<BaseObject>();
if(stream != null){
Gson gson = new Gson();
Reader r = new InputStreamReader(stream);
Log.d(TAG,"Trying to Parse Reader");
try{
objList = gson.fromJson(r, new TypeToken<List<BaseObject>>() {}.getType() );
} catch (JsonSyntaxException e) {
Log.d(TAG, "JsonSyntaxException : " + e.getMessage() );
} catch (JsonIOException e) {
Log.d(TAG, "JsonIOException : " + e.getMessage() );
} finally {
try {
r.close();
} catch (IOException e) {
Log.d(TAG, "IOException : " + e.getMessage() );
}
}
}
Log.d(TAG,"BaseObject[] = " + objList.toString());
return objList;
}
Then I tried this function:
public static BaseObject[] parserInputStreamGsonArray(InputStream stream)
{
BaseObject[] objectArray = null;
if (stream != null) {
Gson gson = new Gson();
Reader r = new InputStreamReader(stream);
Log.d(TAG, "Trying to Parse Reader");
try {
objectArray = gson.fromJson(r, new TypeToken<Event[]>() {}.getType());
} catch (JsonSyntaxException e) {
Log.d(TAG, "JsonSyntaxException : " + e.getMessage());
} catch (JsonIOException e) {
Log.d(TAG, "JsonIOException : " + e.getMessage());
} finally {
try {
r.close();
} catch (IOException e) {
Log.d(TAG, "IOException : " + e.getMessage());
}
}
}
if(eventArray != null){
for(int m=0;m<eventArray.length;m++){
Log.d(TAG, "objectArray[" + String.valueOf(m) + "] = " + objectArray[m].toString());
}
}
return objectArray;
}
And in both cases Gson returned 5 objects, but all of the fields were set to zero.
Finally I got this function to work, but it feels clunky.
public static List<BaseObject> ParseInputStream(InputStream stream) {
Reader r = new InputStreamReader(stream);
List<BaseObject> baseObjectList = new ArrayList<BaseObject>();
try {
JsonParser parser = new JsonParser();
JsonArray array = parser.parse(r).getAsJsonArray();
JsonObject topObject = new JsonObject();
JsonObject subObject = new JsonObject();
for (int m = 0; m < array.size(); m++) {
if (array.get(m).isJsonObject()) {
topObject = array.get(m).getAsJsonObject();
if (topObject.get("BaseObject").isJsonObject()) {
subObject = topObject.get("BaseObject").getAsJsonObject();
BaseObject baseobject = new BaseObject();
baseobject.field1 = subObject.get("field1").getAsLong();
baseobject.field2 = subObject.get("field2").getAsInt();
baseobject.field3 = subObject.get("field3").getAsLong();
baseobject.field4 = subObject.get("field4").getAsInt();
baseobject.field5 = subObject.get("field5").getAsInt();
baseobject.field6 = subObject.get("field6").getAsDouble();
baseobject.field7 = subObject.get("field7").getAsDouble();
baseobject.field8 = subObject.get("field8").getAsLong();
baseObjectList.add(baseobject);
} else {
Log.e(TAG, "topObject[" + String.valueOf(m)+ "].subObject is not a JsonObject");
}
} else {
Log.e(TAG, "Array # " + String.valueOf(m)+ " is not a JsonObject!");
}
}
} catch (Exception ex) {
Log.e(TAG, "Exception thrown = " + ex.toString());
ex.printStackTrace();
}
return baseObjectList;
}
Here is the class I created for BaseObject.
public class BaseObject {
#SerializedName("field1")
public long field1;
#SerializedName("field2")
public int field2;
#SerializedName("field3")
public long field3;
#SerializedName("field4")
public int field4;
#SerializedName("field5")
public int field5;
#SerializedName("field6")
public double field6;
#SerializedName("field7")
public double field7;
#SerializedName("field8")
public long field8;
#Override
public String toString() {
return "(" +
"field1= " + String.valueOf(this.field1) + ", " +
"field2= " + String.valueOf(this.field2) + ", " +
"field3= " + String.valueOf(this.field3) + ", " +
"field4= " + String.valueOf(this.field4) + ", " +
"field5= " + String.valueOf(this.field5) + ", " +
"field6= " + String.valueOf(this.field6) + ", " +
"field7= " + String.valueOf(this.field7) + ", " +
"field8= " + String.valueOf(this.field8) +
")";
}
}
Can anyone tell me how I need to structure my data classes in order use Gson.fromJson to work.
Since your response is actually List<BaseObject>, you should be using
List baseObjectList = new Gson().fromJson(r,new TypeToken>() {}.getType())
Also I should mention that, you do not really need to use the #SerializedName annotations since your attribute names in the json reply and in the class are same.
UPDATE:
Oops.. Sorry, I should have tried your code before answering. Please refer to the following code. Everything boiled down to the Structuring of classes.
public class Sample {
public static class Wrapper{
private BaseObject BaseObject;
#Override
public String toString() {
return BaseObject == null? null : BaseObject.toString();
}
}
public static void main(String[] args) {
// TODO Auto-generated method stub
String json = "[{\"BaseObject\": {\"field1\":\"1\",\"field2\":\"1639\",\"field3\":\"10\",\"field4\":\"1\",\"field5\":\"12\",\"field6\":\"10.765984\",\"field7\":\"-25.768357\",\"field8\":\"1327790850\"}},{\"BaseObject\":{\"field1\":\"2\",\"field2\":\"1934\",\"field3\":\"19\",\"field4\":\"30\",\"field5\":\"2\",\"field6\":\"10.758662\",\"field7\":\"-25.769684\",\"field8\":\"1327790850\"}},{\"BaseObject\":{\"field1\":\"3\",\"field2\":\"2567\",\"field3\":\"33\",\"field4\":\"6\",\"field5\":\"98\",\"field6\":\"10.758786\",\"field7\":\"-25.769843\",\"field8\":\"1327790850\"}},{\"BaseObject\":{\"field1\":\"4\",\"field2\":\"0\",\"field3\":\"33\",\"field4\":\"7\",\"field5\":\"0\",\"field6\":\"10.758786\",\"field7\":\"-20.769843\",\"field8\":\"1327790850\"}},{\"BaseObject\":{\"field1\":\"5\",\"field2\":\"1097\",\"field3\":\"33\",\"field4\":\"1\",\"field5\":\"0\",\"field6\":\"15.758786\",\"field7\":\"50.769843\",\"field8\":\"1327790850\"}},{\"BaseObject\":{\"field1\":\"6\",\"field2\":\"1936\",\"field3\":\"50\",\"field4\":\"0\",\"field5\":\"9\",\"field6\":\"19.234987\",\"field7\":\"-67.340065\",\"field8\":\"1327798560\"}}]";
List<Wrapper> results = new Gson().fromJson(json,new TypeToken<List<Wrapper>>(){}.getType());
System.out.println(results);
}
}
Just curious, do you have the liberty to change the JSON reply coming from server? IMHO, Its structure is a little complicated.
Hey anybody can tell me how can i import all yahoo contacts into my android application please , show me proper way dont give me yahoo api etc if u have source code kindly post it
thank you
just create a layout with webview , and use this code to get contacts.
you need oauth libraries,. and replace consumer key and scret with yours.
