Error when using Java REST Client in Android Studio

[fmisso (Fabrice)]

Hello,
I'm trying your Java REST client API in Android Studio.
But i have this error

Caused by: java.lang.NoSuchFieldError: No field INSTANCE of type Lorg/apache/http/message/BasicLineFormatter; in class Lorg/apache/http/message/BasicLineFormatter;

Impossible to find a solution...
I try to exclude httpclient module in my gradle file,

implementation ('org.elasticsearch.client:elasticsearch-rest-client:7.0.1'){
exclude module: 'httpclient'
exclude module: 'httpcore-nio'
exclude module: 'httpcore'
}

But nothing, it doesn't work.
Could you help me, please !
Thanks

I have the same problem. I was thinking about Java API but elastic say it's deprecated. Can someone help? Can we use other http client?

I did not find a solution despite hours of research. Too bad the support is not more active. I took the solution with an AsyncHttpClient object

public class DAOElastic extends JsonHttpResponseHandler{
private String URL;
private AsyncHttpClient client ;
private boolean error;

public DAOElastic(){
    this.URL = "http://192.168.1.154:9200/";
    this.client = new AsyncHttpClient();
    this.error = false;
}

public void get(String url, RequestParams params) {
    this.client.get((this.URL+url), params, this);
}

public void post(String url, RequestParams params) {
    this.client.post((this.URL+url), params, this);
}

@Override
public void onSuccess(int statusCode, Header[] headers, JSONObject response) {
    // If the response is JSONObject instead of expected JSONArray
    this.error = false;
    this.deserialiseMedicaments(response);
}

@Override
public void onSuccess(int statusCode, Header[] headers, JSONArray response) {
    //Log.i(CLASS_NAME, "onSuccess: " + response.toString());


}

@Override
public void onFailure(int statusCode, Header[] headers, String responseString, Throwable throwable) {
    super.onFailure(statusCode, headers, responseString, throwable);
    // called when response HTTP status is "4XX" (eg. 401, 403, 404)
    this.error = true;
}

@Override
public void onRetry(int retryNo) {
    Log.i("Test", "onRetry " + retryNo);
    // called when request is retried
}

@Override
public ArrayList<Object> getObjects() {
    this.get("myobj/_search", null);
    if (this.error == false){
        return null;
    }
    else{
        return null;
    }
}

}

Not the better solution, but it's work.
