After getting the following code to work reliably for a month or so, it stopped working reliably a couple of days ago. About half the time it returns a properly translated string and the other half of the time it returns one of the following two messages:
java.io.FileNotFoundException:
https://api.cognitive.microsoft.com/sts/v1.0/issueToken
java.net.UnknownHostException: Unable to resolve host
"api.microsofttranslator.com": No address associated with hostname
The timing of this problem's beginning coincided with the expiration of my free azure cognitive services account however I migrated to a pay-as-you-go account yesterday and the problem continues.
Why is this happening?

Host not found looks like a simple connectivity error. These hosts do exist.
You can void the call to the token service by passing the key in the call to api.microsofttranslator.com directly:
https://cognitive.uservoice.com/knowledgebase/articles/1815385-api-translator-text-speech-using-the-api-key
That fixes one of the host not found problems, but not the other.
I would recommend though to not embed the key in the client application. It is safer to call the translator service from your own proxy service, where the proxy is able to safely identify your client as your client.

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

What could be the problem?
Make sure that your system clock is correct. It will be good idea to sync it using NTP. In the past I have seen signature errors when the time is out of sync.
What I've seen before is that this is normally down to permissions . Check access and secret key is correct and you have adequate permissions.
Changed:
Base64.DEFAULT;
To:
Base64.NO_WRAP;
It's hard to tell from the code. A few things to check:
Make sure the service you want to reach uses SigV2 signing (or query string signing). New services follow version 4 signing standard.
URLEncoder.encode doesn't meet AWS' encoding requirement RFC 3986. You need to apply some fixes to the encoded string.
Query strings should be sorted in a case insensitive way.
Your credentials are indeed correct.
It's a good idea to see how QueryStringSigner.java is implemented in the official SDK , and Signature Version 2 Signing Process.
PS: what's the reason of not using the offical SDK?
In the past when I have had this issue, it was to do with system time. Syncing time with NTP fix issue for me
Can be caused by
A space in the name (or path) of the file.
Characters that are not being properly encoded. Mostly / or +.
Generating new keys that does not contain these characters could help. More info on this issue or this one.
I have a ListView that onLongClick it calls a method that is supposed to go out to a website, pull a jsonArray from it and then return information that is pulled from the array. However, when it calls the HttpURLConnection.connect() method it fails and goes to the catch block. When I use the getMessage() message on the exception it only returns Null. This is the second time in this program that I've connected to a URL in this same way and it works the first time perfectly. What could be causing this issue?
Here is the code for when the method is called:
list.setOnItemLongClickListener(new AdapterView.OnItemLongClickListener() {
public boolean onItemLongClick(AdapterView<?> a, View v, int pos, long id) {
String trainNum = list.getItemAtPosition(pos).toString();
String info = "hello";
try {
info = getCurrentTrainInfo(trainNum);
}catch(Exception e){
info = e.getMessage();
if(info == null)
info = "info is null";
tv.setText(info);
}
Toast.makeText(getApplicationContext(), info, Toast.LENGTH_LONG).show();
return true;
}
}
);
And here is the method getCurrentTrainInfo that is called in the try block above:
public String getCurrentTrainInfo(String num) throws IOException{
String sURL = "http://www3.septa.org/hackathon/RRSchedules/" + num;
URL url = new URL(sURL);
HttpURLConnection request2 = (HttpURLConnection) url.openConnection();
request2.connect();
JsonParser jp = new JsonParser();
JsonElement root = jp.parse(new InputStreamReader((InputStream) request.getContent()));
JsonArray rootArr = root.getAsJsonArray();
int i = 0;
String acTime = "";
String station = rootArr.get(i).getAsJsonObject().get("station").getAsString();
String schTime = rootArr.get(i).getAsJsonObject().get("sched_tm").getAsString();
String esTime = rootArr.get(i).getAsJsonObject().get("est_tm").getAsString();
tv.setText(station);
String info = "Current Station: " + station + "\nScheduled leave time: " + schTime + "\nEstimated leave time: " + esTime;*/
return info;
}
Is there anything I can do to fix this problem?
I see your request is being made in the UI thread, you mentioned that in another moment used this same way and it worked, I believe this may have happened when you ran your application on a device/emulator with a version of Android prior to 3.0.
Within an Android application you should avoid performing long
running operations on the user interface thread. This includes file
and network access. StrictMode allows to setup policies in your
application to avoid doing incorrect things. As of Android 3.0
(Honeycomb) StrictMode is configured to crash with a
NetworkOnMainThreadException exception, if network is accessed in
the user interface thread.
You can create a AsyncTasks class and move the call request to it.
I built an android app which can handle a share intent from Google Maps and show it's coordinates.
The problem is that they send a short url which I decode with Google's url shortner api and in some cases, the result long link is of this type: http://maps.google.com/?cid=3635533832900933072&hl=en&gl=us.
Can anyone help me on how to get the coresponding coordinates to "cid=3635533832900933072"
As far as I know there is no public API to get the location from a cid.
However, a possible workaround would be to parse the Google Maps output to obtain the latitude and longitude (though it may be brittle, if they change the result format).
(Although the url contains output=json, it's not actually json -- that's why I parse it with substring() and such instead of using JSONObject).
Try this code:
public static LatLng getCidCoordinates(String cid)
{
final String URL_FORMAT = "http://maps.google.com/maps?cid=%s&q=a&output=json";
final String LATLNG_BEFORE = "viewport:{center:{";
final String LATLNG_AFTER = "}";
final String LATLNG_SEPARATOR = ",";
final String LAT_PREFIX = "lat:";
final String LNG_PREFIX = "lng:";
try
{
HttpClient client = new DefaultHttpClient();
HttpGet get = new HttpGet(String.format(URL_FORMAT, cid));
HttpResponse response = client.execute(get);
String text = EntityUtils.toString(response.getEntity(), "UTF-8");
int startIndex = text.indexOf(LATLNG_BEFORE);
if (startIndex == -1)
return null;
startIndex += LATLNG_BEFORE.length();
int endIndex = text.indexOf(LATLNG_AFTER, startIndex);
// Should be "lat:<number>,lng:<number>"
String[] parts = text.substring(startIndex, endIndex).split(LATLNG_SEPARATOR);
if (parts.length != 2)
return null;
if (parts[0].startsWith(LAT_PREFIX))
parts[0] = parts[0].substring(LAT_PREFIX.length());
else
return null;
if (parts[1].startsWith(LNG_PREFIX))
parts[1] = parts[1].substring(LNG_PREFIX.length());
else
return null;
return new LatLng(Double.parseDouble(parts[0]), Double.parseDouble(parts[1]));
}
catch (NumberFormatException e)
{
e.printStackTrace();
return null;
}
catch (IOException e)
{
e.printStackTrace();
return null;
}
}
After reading this post yesterday, I found a new method to do it. I hope Google do not close this new API and hidden parameter. :)
You can use this API hidden parameter to get the coordinater. Usage: https://maps.googleapis.com/maps/api/place/details/json?cid=YOUR_CID&key=YOUR_KEY
It returns a result contains formatted address, place_id, name of the address and GPS coordinater.
Please see my blog to see more detail: https://leonbbs.blogspot.com/2018/03/google-map-cid-to-placeid-or-get.html
In latest Google Maps update, the share intent contains the address name in the body which can be decoded with Geocoder into coordinates.
