Here this is the layout in which I have to set the image of the user who successfully logged in
and I have saved the url of the image in the table where all the details of the users are there....
So what I was trying is I am fetching the url of the image from the database and then tried to set it into imageview.. I have checked that the url is comming to the variable...
so as you can see in the above image it is not setting the image in imageview but when I assign the url first to the imgurl variable at the time of defining the variable then it works fine...
I don't know why this is happening... am I doing anything wrong or is there any other way to achieve this?
This is the code of the file...

You are fetching image asynchronously, your Asynctask execute will be called with empty imgUrl as it not already fetched, move AsyncTask execution code in onResponse of fetching

use **Glide** to display Image from Url into image view.
You have to add glide lib in app-level build.gradle file.
implementation 'com.github.bumptech.glide:glide:4.12.0'
annotationProcessor 'com.github.bumptech.glide:compiler:4.12.0'
Glide.with(this).load(url)
.transform(CenterCrop(), RoundedCorners(radius))
.placeholder(R.drawable.drawable_image_placeholder)
.error(R.drawable.drawable_image_placeholder)
.into(ivProfile)
drawable_image_placeholder is the default imageview that displays
when getting the error to load the image. ivProfile is imageview .

anybody please suggeest how to get proper access token after login with microsoft/outlook using webview.
Thanks in advance.
How can we pass params from editText to url using request.GET method.
Actually I am trying to pass an email address as parameter to a api which should b attached to api-url .
I came to know from here that getParams() is not called on the GET method, so it seems you'll have to add it to the URL before you send the request.
suggest me any solution to achieve the task ..
when i pass REG_URL="http://ec2-54-147-238-136.compute-1.amazonaws.com/hmc/api/registeruser?email=ameer#novatoresols.com";
it return success=true response as expected because is registered user
but if i set REG_URL="http://ec2-54-147-238-136.compute-1.amazonaws.com/hmc/api/registeruser and pass the params (get value from edittext and use params.put in getparams() method ).response is always success=false i.e params is not attached to url

As suggested by #Puneet worked for me which is as :
getParams is only called for POST requests. GET requests don't have a body and hence, getParams is never called. For a simple request like yours just add the parameters to your URL and use that constructed URL to make that request to your server (REG_URL + "?email=" + email).
To pass the parameters, you need to create a class for the key-value pairs.
1) Create a class KeyValuePair with two fields key and value with appropriate constructor and getter-setter methods.
2) Now, for each parameter, you need to create an object of this class, i.e., for a key username with value user#gmail.com, the object would be new KeyValuePair("username", "user#gmail.com").
3) Now, you need to create a List to store these parameters and pass this list to the below method with your base url,
public static String generateUrl(String baseUrl, List<KeyValuePair> params) {
if (params.size() > 0) {
for (KeyValuePair parameter: params) {
if (parameter.getKey().trim().length() > 0)
baseUrl += "&" + parameter.getKey() + "=" + parameter.getValue();
}
}
return baseUrl;
}
4) Pass this baseUrl to your Request.
I am working on an android project, in which i have to call APIs in english when mobile local language is Arabic. i am not getting API URl String in English.
My API calling file(PackageapiCall.class) is as follows:

My `gettodaydate` method as follows:
public String gettodaysdate(){
DateFormat formatter;
formatter = new SimpleDateFormat("MM-dd-yyyy",Locale.ENGLISH);
String result = formatter.format(new Date());
/*DateFormat dateFormat = new SimpleDateFormat("MM-dd-yyyy");
Date date = new Date();*/
// return dateFormat.format(date);
return result;
}
and finally my string.xml :
<string name="alltrips_api_ta_url" translatable="false">http://roamer.techmaster.in/Rest/api/GetAgentTrips?agentId="%1$d"&isPreviousTrip=false&date="%2$s"</string>
I ma getting log cat as:
Unexpected response code 400 for http://roamer.techmaster.in/Rest/api/GetTrips?mobileUserId=١&isPreviousTrip=false&date=02-14-2017
as i am seeing that mobileUserId is 1 and it is going to convert in url in Arabic when url going to hit to server. app going to crash.Please help me out.Thanks.
After struggle i got an idea and it worked, it is:
i change int to string like:
String userId = String.valueOf(mobileUserId); and then i do
<string name="alltrips_api_ta_url" translatable="false">http://base_url/trips?agentId="%1$d"&isPreviousTrip=false&date="%2$s"</string>
to
<string name="alltrips_api_ta_url" translatable="false">http://base_url/GetAgentTrips?agentId="%1$s"&isPreviousTrip=false&date="%2$s"</string>
and then i put
String url = ctx.getResources().getString(R.string.alltrips_api_url,userId ,gettodaysdate);
in your getHeaders() add the Content-Type
#Override
public Map<String,String> getHeaders() throws AuthFailureError {
HashMap<String,String> headers = new HashMap<String, String>();
headers.put("Content-Type", "application/json; charset=utf-8");
return headers;
}
Also override getBodyContentType() and return "application/x-www-form-urlencoded; charset=UTF-8";
#Override
public String getBodyContentType() {
return "application/x-www-form-urlencoded; charset=UTF-8";
}
