I just copy all the jar files of

Http
but
Android Studio
cann't import all these jar files.It gives an error :
Cannot resolve symbol HttpGet,HttpClient,HttpResponse
.

My
Activity
file is here:-

public class MainActivity extends AppCompatActivity {

ArrayList<Product> productslist;
ProductAdapter adapter;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);


productslist = new ArrayList<Product>();
new JSONAsyncTask().execute("http://opencart.codeniques.com/myshop/?route=feed/web_api/products&id=60&key=test123");

ListView listView = (ListView)findViewById(R.id.list);
adapter = new ProductAdapter(getApplicationContext(),R.layout.row,productslist);

listView.setAdapter(adapter);

listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
Toast.makeText(getApplicationContext(),productslist.get(position).getName(),Toast.LENGTH_LONG).show();
}
});
}

class JSONAsyncTask extends AsyncTask<String,Void,Boolean>{

ProgressDialog dialog;

@Override
protected void onPreExecute() {
super.onPreExecute();
dialog = new ProgressDialog(MainActivity.this);
dialog.setMessage("Loading, please wait");
dialog.setTitle("Connecting server");
dialog.show();
dialog.setCancelable(false);
}

@Override
protected Boolean doInBackground(String... params) {
try{
HttpGet httppost = new HttpGet(params[0]);
HttpClient httpclient = new DefaultHttpClient();
HttpResponse response = httpclient.execute(httppost);

int status = response.getStatusLine().getStatusCode();

if(status == 200){
HttpEntity entity = response.getEntity();
String data = EntityUtils.toString(entity);

JSONObject jsono = new JSONObject(data);
JSONArray jarray = jsono.getJSONArray("products");

for (int i = 0; i < jarray.length(); i++) {
JSONObject object = jarray.getJSONObject(i);

Product actor = new Product();

actor.setId(object.getString("id"));
actor.setName(object.getString("name"));
actor.setDescription(object.getString("description"));
actor.setHref(object.getString("href"));
actor.setPrice(object.getString("pirce"));
actor.setImage(object.getString("thumb"));
actor.setSpecial(object.getString("special"));
actor.setRating(object.getString("rating"));

productslist.add(actor);
}
return true;
}
}catch (JSONException e){
Log.e("Error :",e.getMessage());
}catch (ParseException e){
Log.e("Error :",e.getMessage());
}catch (IOException e){
Log.e("Error :",e.getMessage());
}catch (Exception e){
Log.e("Error :",e.getMessage());
}
return false;
}
@Override
protected void onPostExecute(Boolean aBoolean) {
dialog.cancel();
adapter.notifyDataSetChanged();
if(aBoolean == false){
Toast.makeText(getApplicationContext(), "Unable to fetch data from server", Toast.LENGTH_LONG).show();
}
}
}}


and here my
gradle
is here:-

apply plugin: 'com.android.application'
android {
compileSdkVersion 23
buildToolsVersion "22.0.1"

defaultConfig {
applicationId "android.catalyst.com.newjsonarray"
minSdkVersion 16
targetSdkVersion 23
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}}}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])

testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:23.0.1'
compile 'com.android.support:design:23.0.1'}

Answer

Just add this in your dependencies

compile 'org.apache.httpcomponents:httpcore:4.4.1'
compile 'org.apache.httpcomponents:httpclient:4.5'

Finally

dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])    
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:23.0.1'
compile 'com.android.support:design:23.0.1'
compile 'org.apache.httpcomponents:httpcore:4.4.1'
compile 'org.apache.httpcomponents:httpclient:4.5'
}

Edit

You can add

 android {
    useLibrary 'org.apache.http.legacy'
         }

I hope it helps you.
