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'}
This question is related to
android
android-studio
android-support-library
Please remove all jar
files of Http from 'libs' folder and add below dependencies in gradle file:
compile 'org.apache.httpcomponents:httpclient:4.5'
compile 'org.apache.httpcomponents:httpcore:4.4.3'
or
useLibrary 'org.apache.http.legacy'
HttpClient was deprecated in API Level 22 and removed in API Level 23.
You have to use URLConnection
.
HttpClient is not supported any more in sdk 23. You have to use URLConnection or downgrade to sdk 22 (compile 'com.android.support:appcompat-v7:22.2.0')
If you need sdk 23, add this to your gradle:
In dependencies add:
compile 'org.apache.httpcomponents:httpcore:4.4.1'
compile 'org.apache.httpcomponents:httpclient:4.5'
and also add this
android {
useLibrary 'org.apache.http.legacy'
}
You just rebuilt your project
compile fileTree(dir: 'libs', include: ['*.jar'])
please add these codes to your dependencies. It will work.
implementation 'org.jbundle.util.osgi.wrapped:org.jbundle.util.osgi.wrapped.org.apache.http.client:4.1.2'
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
testCompile 'junit:junit:4.12'
implementation 'com.android.support:appcompat-v7:23.1.0'
implementation 'com.android.support:design:23.1.0'
implementation 'com.android.support:cardview-v7:23.1.0'
implementation 'com.android.support:recyclerview-v7:23.1.0'
implementation 'org.jbundle.util.osgi.wrapped:org.jbundle.util.osgi.wrapped.org.apache.http.client:4.1.2'
}
adding this worked for me.
compile 'org.jbundle.util.osgi.wrapped:org.jbundle.util.osgi.wrapped.org.apache.http.client:4.1.2'
That is just in SDK 23, Httpclient and others are deprecated. You can correct it by changing the target SDK version like below:
apply plugin: 'com.android.application'
android {
compileSdkVersion 22
buildToolsVersion "22.0.1"
defaultConfig {
applicationId "vahid.hoseini.com.testclient"
minSdkVersion 10
targetSdkVersion 22
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:22.1.1'
}
Please remove all jar files of Http from libs folder and add below dependencies in gradle file :
compile 'org.apache.httpcomponents:httpclient:4.5'
compile 'org.apache.httpcomponents:httpcore:4.4.3'
Thanks.
Just add this line of code in your build.gradle file and it will work.
implementation 'org.jbundle.util.osgi.wrapped:org.jbundle.util.osgi.wrapped.org.apache.http.client:4.1.2'
Also add these below line if above did not work at all.
compile 'com.google.android.gms:play-services:+'
compile ('org.apache.httpcomponents:httpmime:4.2.6'){
exclude module: 'httpclient'
}
compile 'org.apache.httpcomponents:httpclient:4.2.6'
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'
For me, the below helped
Find org.apache.http.legacy.jar
which is in Android/Sdk/platforms/android-23/optional,
add it to your dependency.
Google officially suggests to developers to use Volley library for networking related stuff Here, so Its time to switch to Volley, Happy coding
