I read the thread OkHttpClient cannot cancel Call by tag but it's not working for me. I have a EditText
with TextWatcher
to get Places address using Google PlacesAutocomplete, so each char typed is a new request, but each char that I type i need to cancel the previous request so I don't receive the return of it, cu'z what matters is the final Address typed, I did this :
Update!
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 call = new OkHttpClient().newCall(request);
call.enqueue(new Callback() {
@Override
public void onFailure(Call call, IOException e) {
}
@Override
public void onResponse(Call call, Response response) throws IOException {
Log.d("Response",response.body().string());
PlacePredictions place = LoganSquare.parse(response.body().string(),PlacePredictions.class);
if(autoCompleteAdapter == null){
autoCompleteAdapter = new AutoCompleteAdapter(CustomPlaces.this);
recyclerView.setAdapter(autoCompleteAdapter);
autoCompleteAdapter.Add(place.getPlaces());
}else {
autoCompleteAdapter.Clear();
autoCompleteAdapter.Add(place.getPlaces());
autoCompleteAdapter.notifyDataSetChanged();
}
}
});
//call.cancel();
}
The Exception :
E/AndroidRuntime: FATAL EXCEPTION: OkHttp Dispatcher

How's about trying another approach to your issue? You can make something like this with OkHttp
without using asyncTask
:
Call call = new OkHttpClient().newCall(your request);
call.enqueue(new Callback() { // call off UI thread.
@Override
public void onFailure(Call call, IOException e) {
// this is where your call is cancelled: call.isCanceled()
}
@Override
public void onResponse(Call call, Response response) throws IOException {
}
});
call.cancel(); // this is the proper way to cancel an async call.
: :
You should notice that the response body is a one-shot value that may be consumed only once
and you should not call response.body().string()
twice. Just make a local variable: responseString = response.body().string()
and use it onlye.
