How to build a URL in Koush ion

I am building an app to upload images to my company server
I am using koush-ion for the upload,
now my problem is I have to dynamically change the URL for upload depending on information entered in another activity(LoginActivity) via edittext boxes
and I don't understand how to do that
so what I want to happen is the client enters thier Email, password and clientID(4 digits)(in LoginActivity) and the app uses that to build a url for the upload
like this one(in CameraActivity)
https://www.blahpractice.co.za/files-upload-ruben.asp?MyForm=Yes&ClientID=1234&Username=man#blahpractice.co.za&Pwd=BlahBlah123#
I got this From the koush github, and i am unsure if this is what i am looking for and also how to implement data from another activity in koush-ion
Post application/x-www-form-urlencoded and read a String
Ion.with(getContext())
.load("https://koush.clockworkmod.com/test/echo")
.setBodyParameter("goop", "noop")
.setBodyParameter("foo", "bar")
.asString()
.setCallback(...)

You could store the url on the shared preferences and retrieve it every time you execute your upload task and set it on the .load() method.
Also, what you need to send an image to your server is a multipart post. I haven't used Ion but I have used multipart in other libraries like OkHttp, I´ve copied the method that appears on the Ion documentation:
String dynamicUrl = PreferenceManager.getDefaultSharedPreferences(context).getString(CURRENT_SELECTED_URL, null);
File myImage = new File(myImagePath);
if(dynamicUrl != null) {
Ion.with(getContext())
.load(dynamicUrl)
.uploadProgressBar(uploadProgressBar)
.setMultipartParameter("goop", "noop")
.setMultipartFile("myImageName", "image/*", myImage)
.asJsonObject()
.setCallback(...)
}

This is my class and i am trying to capture an image on click a button and then save into directory after that show into imageview and then want to send to server,i hope you will help me as a best programmer.

this question may be a duplicate of this.
Basically, when you pass an OutPut file to the intent, you cannot read data from extra, you have to make sure that CameraApplication has access to your files. You are getting this exception, because CameraApplication cannot save the file on your directory, you need to add a file provider...
Please make your code is same as the base android documentation.

Try This
public void getFile(View view) {
if (ContextCompat.checkSelfPermission(UploadDocumentActivity.this, Manifest.permission.CAMERA)
!= PackageManager.PERMISSION_GRANTED){
ActivityCompat.requestPermissions(UploadDocumentActivity.this,new String[]{Manifest.permission.CAMERA},
MY_CAMERA_PERMISSION_CODE);
} else {
Intent i=new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
File dir=
Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DCIM);
String pictureNm = getPictureName();
File output=new File(dir, pictureNm);
i.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(output));
startActivityForResult(cameraIntent, CAMERA_REQUEST);
}
}

String image = getStringImage(bitmap);
bitmap is not defined anywhere in the code shown in your question, and it is not assigned a value in the code shown in your question. Apparently, bitmap is null. Either assign the appropriate value to bitmap or pass some other non-null value to getStringImage().
