0) I am using Retrofit 2 for work with Bank API.
1) I have some interface:

public interface ApiService {
    @GET("statdirectory/exchange")
    Call<List<MyModel>>  getСurrency(@Query("date") String inputDate);
}

2) And when i call method getСurrency(someParametr), where someParametr is string, consist with "date&json" (for example, "20170917&json"):

ApiService apiService = RetrofitController.getApi();
apiService.getCurrency("20170917&json").enqueue(new Callback<List<MyModel>>() {

      @Override
      public void onResponse(Call<List<MyModel>> call, Response<List<MyModel>> response) {
          call.request().url();
          Log.e("URL",  call.request().url()+"");
          response.code();
          Log.e("CODE", response.code()+"");      
}
//.....

3) I see that:
URL: "https://bank.gov.ua/NBUStatService/v1/statdirectory/exchange?date=20170917%26json" (& is replaced by %26)
CODE: "404"
4) Inmy interface i add encoded:

getСurrency(@Query(value="date", encoded=false) String inputDate);

But my result is the same as in step 3!

5) How to check this problem? How to get URL without %26 on my string? I read other questions with similar problem, but isn't solve my problem. Thanks!

I just wanted to clarify that the original problem was that the encoded parameter needed to be true: encoded=true. This indicates that the value provided is already encoded and thus doesn't need to be re-encoded by retrofit. As is stated in the retrofit documentation, the default value of encoded is false. ie:

getСurrency(@Query(value="date", encoded=true) String inputDate);

will result in the correct url being generated.

The documentation states the following regarding the encoded parameter:

Specifies whether the parameter name and value are already URL encoded.

If you still got this problem, I have 2 solutions.

FIRST SOLUTION:

// Create a URL object and pass to constructor your url
URL urlObject = new URL(url);
// Create connection
HttpURLConnection connection = (HttpURLConnection) urlObject.openConnection();
// SET 'GET' request
connection.setRequestMethod("GET");
connection.connect();
// Create stream to read output
InputStream inputStream = connection.getInputStream();

// Craete buffer to gain all output
StringBuffer stringBuffer = new StringBuffer();
AND HERE IS THE KEY
YOU CREATE A BUFFERREADER AND SET CP1251 SO URL`S GONNA BE ENCODED
BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(inputStream, "cp1251"));
// Read untill end
String line;
while ((line = bufferedReader.readLine()) != null) {
    stringBuffer.append(line);
}
// HERE IS YOUR JSON RESULT
resultJson = stringBuffer.toString();

SECOND SOLUTION:

Just add encoded = true to your @Query annotation

@GET("some_path")
    Call<RequestBody> function(@Query(value = "param", encoded = true) String your_param);

That's it! All that worked well for me. If you have some comments or questions, I will answer them.
