Could you please explain Square's Retrofit response parsing logic. I'm interested in case when we should receive & parse a big json (>100Kb) - will Retrofit wait while all content will be received from server and only than parse it, or it will start to parse it immediately while getting stream data? My goal is to speedup response processing. Are there any options about it available to configure? As soon as the HTTP client parses the headers, the InputStream will be handed back to Retrofit which will then hand it directly to the Converter . This means that as the underlying converter mechanism

I'm targeting a REST web service from Android 4.0 using HttpsURLConnection . This works fine unless I try to POST something. This is the relevant code section: connection.setDoOutput(true); connection.setChunkedStreamingMode(0); ByteArrayOutputStream out = new ByteArrayOutputStream(); serializeObjectToStream(out, object); byte[] array = out.toByteArray(); connection.getOutputStream().write(array, 0, array.length); This throws the following exception: java.net.HttpRetryException: Cannot retry streamed HTTP body From debugging I realized that the output stream I get via connection.getOuputStream

It seems multicast reception does not work on some Android devices. I can not receive multicast with 4 out of 13 test devices. On those 4 devices it seems the app does not send the IGMP request to join the multicast group. The code to receive the multicast looks like so: WifiManager wifiManager = (WifiManager)context.getSystemService(Context.WIFI_SERVICE); WifiManager.WifiLock wifiLock = wifiManager.createWifiLock(WifiManager.WIFI_MODE_FULL_HIGH_PERF, TAG); WifiManager.MulticastLock multicastLock = wifiManager.createMulticastLock(TAG); multicastLock.setReferenceCounted(true); wifiLock.acquire(

With the release of API level 26, my app's core functionality broke, this being, changing the users' hotspot setting within the application. To get and set this configuration I am using the following functions from the WifiManager hidden api: getWifiApConfiguration and setWifiApConfiguration . Method getWifiApConfiguration = wifiManager.getClass().getMethod("getWifiApConfiguration"); getWifiApConfiguration.invoke(wifiManager); This is working with devices prior to Android O, but in this version I get the following error: App not allowed to read or update stored WiFi Ap config (uid = 10168) The

I would like to know why wifi is connected but there is no internet access in Android. How can i check it? My code is: ConnectivityManager cn=(ConnectivityManager)getSystemService(Context.CONNECTIVITY_SERVICE); NetworkInfo nf=cn.getActiveNetworkInfo(); if(nf != null && nf.isConnected() ) { Flag2=false; Log.e("network--------", "1--------------"); if (cn.getActiveNetworkInfo().isConnectedOrConnecting()) {Log.e("network--------", "11111111111111--------------"); } else {Log.e("network--------", "2222222222222--------------"); } } else { Log.e("network--------", "2--------------"); } You could

I'm making a volley request in this way: public void makeRequest(BaseRequest request, Response.Listener<JSONObject> responseListener, Response.ErrorListener errorListener) { if (Constants.DEBUG) Log.i(TAG, "Sending: " + request.getUrlRequest()); JsonObjectRequest jsObjRequest = new JsonObjectRequest(METHOD, request.getUrlRequest(), null, responseListener, errorListener); // disable cache jsObjRequest.setShouldCache(false); jsObjRequest.setTag(mTag); mQueue.add(jsObjRequest); } mTag is a Class type. I have an activity where on its onCreate method I call the volley request with this:

I have a problem with checking internet connection in android at runtime. I use some different methods to check internet connection but i don't know which one is better . because each of them have some problems . Method 1 check internet connection by pinging Google : Runtime runtime = Runtime.getRuntime(); try { Process mIpAddressProcess = runtime.exec("/system/bin/ping -c 1 8.8.8.8"); int mExitValue = mIpAddressProcess.waitFor(); return mExitValue == 0; } catch (InterruptedException | IOException ignore) { ignore.printStackTrace(); } Method 2 check internet connection by ConnectivityManager :
