AndroidNetworking lib not logging anything

I'm trying to reach an API with AndroidNetworking lib.
Here is how I initalized it:
public class TestLabApp extends Application {
#Override
public void onCreate() {
super.onCreate();
//For logging
RealInterceptor realInterceptor = new RealInterceptor();
realInterceptor.enableLoggingForBody(true);
realInterceptor.enableLoggingForUrl(true);
realInterceptor.enableLoggingForHeaders(true);
realInterceptor.enableLoggingForHttpStatusCodes(true);
realInterceptor.enableLoggingForExecutionTime(false);
//Add logging to okHttpClient
OkHttpClient okHttpClient = new OkHttpClient()
.newBuilder()
.addNetworkInterceptor(realInterceptor)
.build();
//Init AndroidNetworking lib with the okHttpClient (with aloggint interceptor)
AndroidNetworking.initialize(getApplicationContext(), okHttpClient);
}
}
I've added this to the manifest too:
<application
android:name=".TestLabApp"
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:networkSecurityConfig="#xml/network_security_config"
android:roundIcon="#mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="#style/AppTheme">
<activity android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
This is my own interceptor, because the one in the doc's example is simply not part of the lib.
public class RealInterceptor implements Interceptor {
private boolean logUrl = true;
private boolean logBody = true;
private boolean logHeaders = true;
private boolean logHttpStatusCodes = true;
private boolean logExecutionTime = true;
public void enableLoggingForUrl(boolean logUrl) {
this.logUrl = logUrl;
}
public void enableLoggingForHeaders(boolean logHeaders) {
this.logHeaders = logHeaders;
}
public void enableLoggingForBody(boolean logBody) {
this.logBody = logBody;
}
public void enableLoggingForHttpStatusCodes(boolean logHttpStatusCodes) {
this.logHttpStatusCodes = logHttpStatusCodes;
}
public void enableLoggingForExecutionTime(boolean logExecutionTime) {
this.logExecutionTime = logExecutionTime;
}
private void logInfo(Object o) {
Log.i(getClass().getSimpleName(), o.toString());
}
private void logError(Object o) {
Log.e(getClass().getSimpleName(), o.toString());
}
#Override
public Response intercept(Chain chain) throws IOException {
StringBuilder sb = new StringBuilder();
Request request = chain.request();
RequestBody requestBody = request.body();
boolean hasRequestBody = requestBody != null;
if (logUrl) {
sb.append("\nURL: " + request.url());
}
if (logBody) {
if (hasRequestBody) {
Buffer buffer = new Buffer();
requestBody.writeTo(buffer);
String bodyParams = buffer.readString(Charset.forName("UTF-8"));
bodyParams = bodyParams.replace("&", "\nParam: ");
sb.append("\nParam: " + bodyParams);
} else {
sb.append("\nParam: <No params>");
}
}
if (logHeaders) {
Headers headers = request.headers();
String headersStr = "";
for (int i = 0, count = headers.size(); i < count; i++) {
headersStr += "\nHeader: " + headers.name(i) + ": " + headers.value(i);
}
sb.append(headersStr);
}
long startNs = System.nanoTime();
Response response;
try {
response = chain.proceed(request);
} catch (Exception e) {
throw e;
}
if (logHttpStatusCodes) {
sb.append("\nHTTP Status code: " + response.code());
}
long tookSec = TimeUnit.NANOSECONDS.toSeconds(System.nanoTime() - startNs);
long tookMs = TimeUnit.NANOSECONDS.toMillis(System.nanoTime() - startNs);
if (logExecutionTime) {
if (tookSec > 1) {
sb.append("\nExecution time: " + tookSec + " sec");
} else {
sb.append("\nExecution time: " + tookMs + " ms");
}
}
if (response.code() != 200) {
logError(sb.toString());
} else {
logInfo(sb.toString());
}
return response;
}
}
How I'm trying to use it:
AndroidNetworking.post("http://myurlishere.hu/api/test-result/save")
.addBodyParameter("param_1", "12345")
.addBodyParameter("param_2", "abcdef")
.build()
.getAsJSONObject(new JSONObjectRequestListener() {
#Override
public void onResponse(JSONObject response) {
// do anything with response
Log.i("RESP___", response.toString());
codeTv.setText(getString(R.string.please_read_the_qr_code));
enableControls(true);
progressBar.setVisibility(View.INVISIBLE);
zBarScannerView.resumeCameraPreview(MainActivity.this);
Toast.makeText(MainActivity.this, "API done", Toast.LENGTH_SHORT).show();
}
#Override
public void onError(ANError error) {
// handle error
codeTv.setText(getString(R.string.please_read_the_qr_code));
enableControls(true);
progressBar.setVisibility(View.INVISIBLE);
zBarScannerView.resumeCameraPreview(MainActivity.this);
DialogHelper.showInfo(MainActivity.this, "Error: Body: "+error.getErrorBody()+", Response: "+error.getResponse()+", Detail: "+error.getErrorDetail()+", Code: "+error.getErrorCode());
}
});
The problem is:
I don't see ANY logs about what is happening. Why?

Your code looks fine, but I can suggest alternative solution for logging
Firstly it is not necessary to create your own logging, As already package okhttp3.logging Provides HttpLoggingInterceptor which does log all the values which you expected in your RealInterceptor.
Here is an alternative solution :
val logging = HttpLoggingInterceptor()
logging.level = HttpLoggingInterceptor.Level.BODY
okHttpClientBuilder!!.addInterceptor(logging)
In your case :
//Add logging to okHttpClient
var okHttpClient = OkHttpClient()
.newBuilder()
.addNetworkInterceptor(logging)
.build()
Hope this helps, in case release mode of the application you can disable logging by just adding condition:
var okHttpClientBuilder = OkHttpClient()
.newBuilder()
if (BuildConfig.DEBUG) {
okHttpClientBuilder.addNetworkInterceptor(logging)
}
var okHttpClient = okHttpClientBuilder.build()

Network Interceptors
Able to operate on intermediate responses like redirects and retries.
Not invoked for cached responses that short-circuit the network.
Observe the data just as it will be transmitted over the network.
Access to the Connection that carries the request.
I think your request have a cache and NetworkInterceptor will not working. Try to use addInterceptor instead of addNetworkInterceptor. It will work fine.

I think you might be lacking a no-args constructor, as the new keyword requires it:
public RealInterceptor() {}
Try to add it and it should return an instance. But better switch to Retrofit2 from some obviously abandoned library with roughly 200 open issues; there you can use the same Interceptor.

I did not quite understood as to why you are implementing Interceptor and making your own implementation of the Interceptor? Like do you need some custom logging features that is not provided in the library itself?
If all you need is to log headers and/or body of the request/response, the README file mentions that you can do so by simply enabling Logging.
AndroidNetworking.enableLogging(); // simply enable logging
AndroidNetworking.enableLogging(LEVEL.HEADERS); // enabling logging with level
It seems there are different levels that you can provide:
public enum Level {
/**
* No logs.
*/
NONE,
/**
* Logs request and response lines.
* <p>
* <p>Example:
* <pre>{#code
* --> POST /greeting http/1.1 (3-byte body)
*
* <-- 200 OK (22ms, 6-byte body)
* }</pre>
*/
BASIC,
/**
* Logs request and response lines and their respective headers.
* <p>
* <p>Example:
* <pre>{#code
* --> POST /greeting http/1.1
* Host: example.com
* Content-Type: plain/text
* Content-Length: 3
* --> END POST
*
* <-- 200 OK (22ms)

* Content-Length: 6

* }</pre>
*/

* <p>Example:

Let me know if this works for you. Have a nice one :)

Android Retrofit Request Using AWS Signature Authorization

I'm trying to get data from the API which needs to handle aws-authentication, my question is how can I generate Authorization and X-Amz-Date?
I have to pass 3 parameter as header: Content-Type, Authorization and X-Amz-Date.
As you can find in image:
here is the function that generate Authorization String:
public static String gerateOAuthAWS(Context co) throws Exception {
JodaTimeAndroid.init(co);
DateTimeFormatter fmt = DateTimeFormat.forPattern("EEE', 'dd' 'MMM' 'yyyy' 'HH:mm:ss' 'Z").withLocale(Locale.US);
String ZONE = "GMT";
DateTime dt = new DateTime();
DateTime dtLondon = dt.withZone(DateTimeZone.forID(ZONE)).plusHours(1);
String formattedDate = dtLondon.toString(fmt);
String oauth = "AWS4-HMAC-SHA256 Credential="+ ACCESS_KEY+"/us-east-1/execute-api/aws4_request, SignedHeaders=content-type;host;x-amz-date, Signature="+
getSignatureKey(SECRET_KEY,formattedDate,"us-east-1","execute-api");
return oauth;
}
static byte[] HmacSHA256(String data, byte[] key) throws Exception {
String algorithm="HmacSHA256";
Mac mac = Mac.getInstance(algorithm);
mac.init(new SecretKeySpec(key, algorithm));
return mac.doFinal(data.getBytes("UTF8"));
}
static String getSignatureKey(String key, String dateStamp, String regionName, String serviceName) throws Exception {
byte[] kSecret = ("AWS4" + key).getBytes("UTF8");
byte[] kDate = HmacSHA256(dateStamp, kSecret);
byte[] kRegion = HmacSHA256(regionName, kDate);
byte[] kService = HmacSHA256(serviceName, kRegion);
byte[] kSigning = HmacSHA256("aws4_request", kService);
return Base64.encodeToString(kSigning,Base64.DEFAULT).replaceAll("\n", "");
}
Content-Type is "application/x-www-form-urlencoded"
and generate X-Amz-Date something as: "201805138T120046Z"
then pass them through retrofit methods:
#GET("prod/video")
Call<ArrayList<Video>> getAllVideos(#Header("Content-Type")String content_type,
#Header("X-Amz-Date")String amz_date,
#Header("Authorization")String auth);
the result returns null and I'm sure the issue is related the authorization since it worked before well.
thanks for your helps :)

i always said to my friends why do you use retrofit or valley , if it's seems complicated to you !
instead you can use JSOUP or OKHTTP it's much easier and I realy love JSOUP
an example that you can connect and send you data:
private void fcmIdentity(final String fcmKey) {
new Thread(new Runnable() {
#Override
public void run() {
try {
SSLHelper.enableSSLSocket();
Connection.Response response = Jsoup
.connect(Urls.identity)
.header("Accept", "application/json")
.header("KEY_2", "VALUE_2")
.method(Connection.Method.POST)
.ignoreContentType(true)
.ignoreHttpErrors(true)
.validateTLSCertificates(true)
.followRedirects(true)
.data("fcm", "" + fcmKey)
.data("identity", preferences.getString("FCM_ID", ""))
.execute();
Log.i("fcmIdentity", response.statusCode() + "");
Log.i("fcmIdentity", response.toString());
Log.d("fcmIdentity", response.headers().toString());
Log.i("fcmIdentity", response.body());
} catch (Exception e) {
e.printStackTrace();
if (e instanceof IOException) {
G.toast(getString(R.string.connection_error), true);
}
}
}
}).start();
}
about SSLHelper it help to connect to HTTPS

How to push notification to client when Firebase has a new entry?

I wonder if it's possible to send push notifications to android mobile devices whenever Firebase gets added a new child on specific entity.
For example, let's say there's an entity on Firebase called Tasks. Whenever a new task is added to that firebase collection the "child_added" event is fired and then, in some way, a push notification is sent to a mobile client.
The trigger is the child_added event. However, I'm not sure if is feasible sending push notification right from Firebase events.

You can make a very simple node.js server or a java servlet (based on your language preferences) then using firebase server sdk you can add childEventListener. When value changes you can use FCM to send push notifications using http protocol. I am using this in my app and it is very feasable and reliable.
Note: If you are using this flow for an android app then using java server sdk will be beneficial as it is almost similar to what you have on android.
EDIT: After getting some spotlight on this answer I thought to share some more info regarding same.
//example node.js server as seen on this official firebase blog
var firebase = require('firebase');
var request = require('request');
var API_KEY = "..."; // Your Firebase Cloud Server API key
firebase.initializeApp({
serviceAccount: ".json",
databaseURL: "https://.firebaseio.com/"
});
ref = firebase.database().ref();

var requests = ref.child('notificationRequests');
ref.on('child_added', function(requestSnapshot) {
var request = requestSnapshot.val();
sendNotificationToUser(
request.username,
request.message,
function() {
request.ref().remove();
}
);

console.error(error);
});

'Content-Type' :' application/json',
'Authorization': 'key='+API_KEY
},
body: JSON.stringify({
notification: {
title: message
},
to : '/topics/user_'+username
})
}, function(error, response, body) {
if (error) { console.error(error); }
else if (response.statusCode >= 400) {

Edit: you should take a look at Firebase Cloud Functions, which let you do that without having to create a Node.js server

how to send body parameter with multipart file upload request usin ion library?

This is the first time ever I am using multi part request to upload data on the server.I am using ion for service hit can you please let me know how can I post my data on the server?
This is my request parameter
jSON Request:
{s_id
note_name
file_name
tag_name
set_date
mark_as_done
clear_reminder
Description
media_name1
media_name2
media_name3
Count = 3 }
Along with it, I have to upload file media1, media2, media2 on same api**. Any help would be greatly appreciated.Thanks

You can't do a JSON body and a Multipart body in one HTTP request.
you can send your json as a parameter :)
// first create your json object
JsonObject object = new JsonObject();
object.addProperty("note_name", "your value goes here");
object.addProperty("description", "your description goes here");
// add other stuffs here
//create list of files to upload
List<Part> files = new ArrayList<>();
for (int i = 1; i <= 3; i++) {
files.add(new FilePart("file" + i, new File("path of file like: storage/image/....")));
}
Ion.with(context)
.load("POST","http://example.com")
.uploadProgress(new ProgressCallback() {
#Override
public void onProgress(long downloaded, long total) {
int percent = (int) (downloaded * 100 / total);
// update your progressbar with this percent if needed
}
})
.addMultipartParts(files)
.setMultipartParameter("json", object.toString()) // your json is here
.asString()
.setCallback(new FutureCallback<String>() {
#Override
public void onCompleted(Exception e, String result) {
if (e != null) {
// error: log the message here
return;
}
if (result != null) {
// result is the response of your server
}
}
});
Hope this help you :)

hi i have this code the esp will connect to the internet so that i can turn on or turn off led from a mobile appl i want to change it . i want the esp8266 01 ti be an access point .. i don't want to use the internet i want the phone to connect directly to the esp8266
what changes do i have to do and how can i configure esp8266 as access point

When you initialized the ESP, you configured it in Station Mode
sendCommand("AT+CWMODE=1\r\n",1000,DEBUG);
sendCommand("AT+CWJAP=\"SSID\",\"PASSWD\"\r\n",3000,DEBUG);
In order to configure in AP mode you should replace this with :
sendCommand("AT+CWMODE=2\r\n",1000,DEBUG);
See CWMODE documentation
mode：
1 means Station mode
2 means AP mode
3 means AP + Station mode
