Ho appena copiare tutti i file jar di Http ma Android Studio cann't importare tutti questi vaso files.It dà un errore: Cannot resolve symbol HttpGet,HttpClient,HttpResponse.non può risolvere simbolo HttpGet, HttpClient, HttpResponce in Android Studio
Il mio file Activity è qui: -
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();
}
}
}}
e qui il mio gradle è qui: -

testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:23.0.1'
compile 'com.android.support:design:23.0.1'}
utilizzare HttpUrlConnection. invece di HttpClient. Vedere il collegamento [Link] (http://developer.android.com/reference/java/net/HttpURLConnection.html) – Irfan
per quanto so che il client http Apache non è più supportato in marshmallow. iniziare a utilizzare il retrofit –
È necessario utilizzare openConnection, HttpClient è obsoleto – Skynet
