Nathiel Barros :
I need to be able to MANAGER some requests with OKHTTP, using the Google Places AutoComplete
to receive some predictions by typing the Address. The Problem is Each time that I insert a CHAR it will make a new request but at the same time I need to cancel the previous one! Ex : New York City = 13 Requests at the same time! So I'm using a single instance of Call
trying to cancel anything that has been requested but with no success. This is what I did!
Address.addTextChangedListener(new TextWatcher() {
@Override
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
if(Address.getText().toString().length() > 3){
_Address = Address.getText().toString();
if(call != null){
call.cancel();
}
Request request = new Request.Builder()
.url(getPlaceAutoCompleteUrl(_Address))
.addHeader("content-type", "application/json")
.addHeader("User-Agent", "Mozilla/5.0 (Linux; U; Android 4.0.3; en-us; google_sdk Build/MR1) AppleWebKit/534.30 (KHTML, like Gecko) Version/4.0 Mobile Safari/534.30")
.build();
call = client.newCall(request);
call.enqueue(new Callback() {
public void onResponse(Call call, final Response response) throws IOException {
final String result = response.body().string();
runOnUiThread(new Runnable() {
@Override
public void run() {
Log.d("Response",result);
PlacePredictions place = null;
try {
place = LoganSquare.parse(result,PlacePredictions.class);
} catch (IOException e) {
e.printStackTrace();
}
if(autoCompleteAdapter == null){
autoCompleteAdapter = new AutoCompleteAdapter(CustomPlaces.this);
recyclerView.setAdapter(autoCompleteAdapter);
autoCompleteAdapter.Add(place.getPlaces());
}else {
autoCompleteAdapter.Clear();
autoCompleteAdapter.Add(place.getPlaces());
autoCompleteAdapter.notifyDataSetChanged();
}
}
});
}
public void onFailure(Call call, IOException e) {
//fail();
}
});
}else {
if(autoCompleteAdapter != null){
autoCompleteAdapter.Clear();
}
}
}
I check if the call
object is null and cancel the request but still keeps coming!
TomerBu :
What about the following:
//Set tags for your requests when you build them:
Request request = new Request.Builder().
url(url).tag("requestKey").build();
//When you want to cancel:
//A) go through the queued calls and cancel if the tag matches:
for (Call call : mHttpClient.dispatcher().queuedCalls()) {
if (call.request().tag().equals("requestKey"))
call.cancel();
}
//B) go through the running calls and cancel if the tag matches:
for (Call call : mHttpClient.dispatcher().runningCalls()) {
if (call.request().tag().equals("requestKey"))
call.cancel();
}
