I'm struggling for few weeks now with this issue. I'm posting geolocation points to a server using Retrofit 2.0. I'm using a IntentService that I call every now and then when I have a new point to post.
For some reason, the server record the same point multiple time creating LOTS of duplicates. It seems that when I call my service and it's already active, it's will query the points and start a new request using some of the same points as was queried by the previous request. I also delete the point only when the request succeed. Is there a way to wait until executing the next batch of points?
How can I wait until all the processed point are sent to the server?

You can use .execute instead of .enqueue and request will be synchronous, but in this case you should care about creating another thread for it. Create some service with asynсtask for example with queue.

I am struggling with something that really p*sses me off for several hours.
My android app manages to connect to a websoket, and receives json data which for now has worked perfectly, and here is the code for this:
runOnUiThread(new Runnable() {
#Override
public void run() {
mSocket.on("dev0", new Emitter.Listener() {
#Override
public void call(Object... args) {
try {
JSONObject incomingPositionFromSensor = new JSONObject( (String) args[0]);
double the_position = incomingPositionFromSensor.getDouble("position");
CalculateValue(the_position);
} catch (JSONException e) {
e.printStackTrace();
}
}
});
}
});
}
This code above as I said works perfectly, and i get the data in everytime. HOWEVER, HOWEVER, HOWEVER: If i try to receive 2 json-objects at the sametime through this emittener, it does not work!!!!
Here is example when i try to receive multiple JSON objects, and NONE of them works!
runOnUiThread(new Runnable() {
#Override
public void run() {
mSocket.on("dev0", new Emitter.Listener() {
#Override
public void call(Object... args) {
try {
JSONObject incomingTargetFromSensor = new JSONObject( (String) args[0]);
int targetNum = incomingTargetFromSensor.getInt("target_number_count");
showTargetRep(targetNum); //NOT WORKING!
JSONObject incomingPositionFromSensor = new JSONObject( (String) args[0]);
double the_position = incomingPositionFromSensor.getDouble("position");
CalculateValue(the_position); //NOT WORKING!
} catch (JSONException e) {
e.printStackTrace();
}
}
});
}
});
}
In the first example I could receive the position data, and the code is exactly similar as the example above, but for some reasons it can not recevice data when i try to receive another JSON object.
Another example of why I always disliked JSON object.
Any help plz?
The solution at the end was to add multiple try/catches like this:
runOnUiThread(new Runnable() {
#Override
public void run() {
mSocket.on("dev0", new Emitter.Listener() {
#Override
public void call(Object... args) {
try {
JSONObject incomingTargetRepFromSensor = new JSONObject((String ) args[0]);
int target_rep = incomingTargetRepFromSensor.getInt("target_repetition_count");
showTargetRep(target_rep);
} catch (JSONException e) {
e.printStackTrace();
}
try{
JSONObject incomingDataFromSensor = new JSONObject((String ) args[0]);
double the_position = incomingDataFromSensor.getDouble("position");
CalculateValue(the_position);
} catch (JSONException e) {
e.printStackTrace();
}
try{
JSONObject incomingTargetSetFromSensor = new JSONObject((String ) args[0]);
int target_set = incomingTargetSetFromSensor.getInt("target_set_count");
showTargetSet(target_set);
} catch (JSONException e) {
e.printStackTrace();
}
try{
JSONObject incomingRepsFromSensor = new JSONObject((String ) args[0]);
int the_repetitions = incomingRepsFromSensor.getInt("repetitions");
showCurrentReps(the_repetitions);
} catch (JSONException e) {
e.printStackTrace();
}
try{
JSONObject incomingSetsFromSensor = new JSONObject((String ) args[0]);
int the_sets = incomingSetsFromSensor.getInt("sets");
showCurrentSets(the_sets);
} catch (JSONException e) {
e.printStackTrace();
}
}
});
}
});
}

I am using Fabric.io Twitter Kit. Created a custom service class and used Retrofit to convert the interface within that class. Code at the bottom (CustomTwitterApiClient Class).
I either get NullPointerException and if I catch that, I get JSONException. As can be seen in the log, I can get trends response but I cant read it. If I try to readLine() it and append it to a StringBuilder, I get null.
I wrote the code with the guidance of this SO answer.
What I am doing wrong ?
Thanks in advance.
PS: Those extra exception handlers just to get a clean log.

I have an Async task class which gets the name of a web method and run it and I have to wait for the result of that web method, so I used task.execute.get() method which is freezing my UI. the problem is that I want to show a loading dialog when task is executing but when I'm trying to call this method 10 times for 10 web methods, the UI freezes and after executing 10 web methods, loading dialog appears for 1 second.
What can I do to show loading without moving all of my codes into doInBackground? I want to have a class which gets web method info and returns the result. this is my class code:
public class AsyncCallWs extends AsyncTask<String, Void, String> {
private ProgressDialog dialog;
public String methodName="";
private WebService ws;
private ArrayList<ServiceParam> paramsList;
private boolean hasParams;
public AsyncCallWs(Activity activity,String methodName) {
xLog.position();
try {
this.dialog = new ProgressDialog(activity);
this.methodName = methodName;
hasParams = false;
} catch (Exception e) {
xLog.error(e.getMessage());
}
}
public AsyncCallWs(Activity activity,String methodName,ArrayList<ServiceParam> params) {
xLog.position();
try {
this.dialog = new ProgressDialog(activity);
this.methodName = methodName;
this.paramsList = params;
hasParams = true;
} catch (Exception e) {
xLog.error(e.getMessage());
}
}
#Override
protected void onPreExecute() {
this.dialog.setMessage(PersianReshape.reshape("Loading..."));
this.dialog.show();
}
#Override
protected String doInBackground(String... params) {
xLog.position();
String result = "No async task result!";
try {
ws = new WebService(PublicVariable.NAMESPACE, PublicVariable.URL);
if (!hasParams){
result = ws.CallMethod(methodName);
}
else{
xLog.info("THIS METHOD IS: "+ methodName);
result = ws.CallMethod(methodName,paramsList);
xLog.info("THIS RESULT IS: "+ result);
}
} catch (Exception e) {
xLog.error(e.getMessage());
}
return result;
}
#Override
protected void onPostExecute(String result) {
xLog.position();
if (this.dialog.isShowing()) {
this.dialog.dismiss();
}
xLog.info("Output of current AsyncTask is:"+ result);
}
}
And this is the way I'm calling web methods using this class:

Here
result = t.execute().get(); //<<< calling get method
as in doc AsyncTask.get() :
Waits if necessary for the computation to complete, and then retrieves
its result.
so to avoid freezing of Main UI Thread during execution of doInBackground start AsyncTask without calling get method as|:
t.execute();
I want to have a class which gets web method info and returns the
result
For this you should implement callback with AsyncTask which report to Activity. see following examples :
android asynctask sending callbacks to ui
How to implement callback with AsyncTask
How Display the posts in facebook application. I tried to work with sample android API for Facebook. But nothing worked fine. I need to display a post that i post on my Facebook wall in android emulator. I need a sample code to run and display the JSON response as my post.
Please send me few working links.
Attach the given code with your facebook login class
public void postOnWall() {
try {
String response = Config.facebook.request("me");
Bundle parameters = new Bundle();
parameters.putString("access_token", Config.myAccessToken);
parameters.putString("message", "I am Now On FB");
parameters.putString("description", "");
response = Config.facebook.request("me/feed", parameters,
"POST");
if (response == null || response.equals("") ||
response.equals("false")) {
}
} catch(Exception e) {
e.printStackTrace();
}
