I am using Retrofit connect electronic devices .but it responding with incorrect data.
Please suggest me some solution to this problem. Do you guys have any idea is it related to connect ?
myUrl :http://11.10.88.23/ajax_control&/
Interface Exapi
public interface ExApi {
#GET("/ajax_control&")
public void getFeed(Callback<Document> response);
}
Mainclass
public class MainActivity extends Activity implements RequestInterceptor{
Button mButton;
public static final String BASE_URL="http://11.10.88.23/";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
mButton = (Button) findViewById(R.id.button);
mButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
requestData(BASE_URL);
}
});
}
private void requestData(String url){
RestAdapter adapter=new RestAdapter.Builder()
.setEndpoint(url).build();
ExApi api=adapter.create(ExApi.class);
api.getFeed(new Callback<Document>() {
#Override
public void success(Document document, Response response) {
Toast.makeText(getApplicationContext(), "value: " + document.getElementsByTagName("LED").item(0).getChildNodes().item(0).getNodeValue(), Toast.LENGTH_SHORT).show();
}
#Override
public void failure(RetrofitError retrofitError) {
Log.d("lai loi: ", retrofitError.getMessage());
}
});
}
#Override
public void intercept(RequestFacade requestFacade) {
final String author=encodeCredentialsForBasicAuthorization();
requestFacade.addHeader("Authorization", author);
}
private String encodeCredentialsForBasicAuthorization() {
final String userAndPassword = "user:admin";
return "Basic " + Base64.encodeToString(userAndPassword.getBytes(), Base64.NO_WRAP);
}
}
Error 401 unauthorized means request is denied due to invalid credentials. This kind of authentication is called Basic Authentication, and you can pass these parameters in an HTTP header as well.
Here's an article about how that can be done in Retrofit: https://futurestud.io/blog/android-basic-authentication-with-retrofit/

I'm new on android development, so decided to learn simple login using MVP architectural pattern, in general everything is working fine, as checking user credentials, calling repository...etc.
However, only the implementations of showProgress() & hideProgress() that works in a weird way, for me at least.
Note that the showProgress() only works if the user inter valid credentials.
Thanks.

Thanks to h4rd4r7c0r3 and Ionut J. Bejan, for highlighting several aspects i wasn't a ware of, in particular Working Thread(UI THREAD) and Another Thread(Background Thread).
Although i don't know yet how to implement them very well, i found way after searching the internet.
The main scenario are:
When the user enter username and password, UI should show indication
(Progress Bar) checking credentialiy of the user, implementing
showProgress().
When the checking is finished, UI should stop the indication.
implementing hideProgress().
An action to be taken based on the result, for example: Navigate to
new Activity or Toast "Wrong Username/Passowrd".
//LoginActivity
#Override
public void showProgress() {
progressBar.setVisibility(View.VISIBLE);
}
#Override
public void hideProgress() {
progressBar.setVisibility(View.GONE);
}
// LoginPresenter
public void onLoginClicked() {
String username = view.getUsername();
if (username.isEmpty()){
view.showUsernameError();
view.hideProgress();
return;
}
String password = view.getPassword();
if (password.isEmpty()){
view.showPasswordError();
view.hideProgress();
return;
}
view.showProgress();
service.login(username,password, this);
}
#Override
public void isUserLoggedIn() {
if(sharedPrefManager.isLoggedIn())
view.navigateHome();
}
// implementing onFinished from FinishedListiner interface, to capture the result
#Override
public void onFinished(boolean bool) {
view.hideProgress();
if (bool){
sharedPrefManager.userLogin(view.getUsername());
view.navigateHome();
return;
}
view.showLoginError();
}
// Service, which will connect to the datasource
public class LoginServiceImpl implements LoginContract.Service {
UserRepository userRepository;
#Override
public void login(final String username, final String password, final FinishedListiner listener) {
userRepository = UserRepositoryImpl.getInstance();
new Handler().postDelayed(new Runnable() {
#Override
public void run() {
// The method which will be used in the presenter class.
listener.onFinished(userRepository.checkUser(username, password));
}
}, 1200);
}
Try this below snippet :
Step 1:- Create BaseActivity extend to AppCompactActivity
Step 2:-Setting BaseActivity as per your requirement
Step 3:-Create Instance of your Progress Dialog
Step 4:-Create function showProgress()
Like:-
private fun showProgress(){
if(!progress.isShowing){
progress.show()
}
}
Step 5:- Create function HideProgress()
Like:-
private fun hideProgress(){
if(progress.isShowing){
progress.dismiss()
}
}
And use as per your requirement.
Your View just run presenter on another thread. See your Handler. Then it update the view and can not access to the UI. To fix this, just make sure your showProgress() is doing work on UI thread.
runOnUiThread(new Runnable() {
public void run() {
//show your proress here.
}
});
I am learning MVP design for the Android , I am new to it so need your valuable time . I went to the basics of the MVP how it work , Now i got stuck so need your help , I have to post the data to the server , when i hard code the value in presenter then i get the response correct but i need the data that is in the LoginActivity view when user press then that value should pass to the presenter and presenter pass that value to the Retrofit and bring back the result . Here is my try :
My LoginActvity:
public class LoginActivity extends BaseActivity implements LoginView {
#BindView(R.id.company_name)
protected EditText companyName_et;
#BindView(R.id.email)
protected EditText email_et;
#BindView(R.id.password)
protected EditText password_et;
#BindView(R.id.submit)
protected Button submit_btn;
#Inject
LoginPresenter loginPresenter;
#Override
protected int getContentView() {
return R.layout.login_activity;
}
#Override
protected void onViewReady(Bundle savedInstanceState, Intent intent) {
super.onViewReady(savedInstanceState, intent);
submit_btn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
String company=companyName_et.getText().toString();
String username=email_et.getText().toString();
String password=password_et.getText().toString();
/*
I have to put the above String data
to my model class then i have to post the data to the server
*/
loginPresenter.passLoginDataToServer();
}
});
}
#Override
public void onError(String s) {
Toast.makeText(this, s, Toast.LENGTH_SHORT).show();
}
#Override
public void onSuccess(String s) {
}
#Override
public void onResponse(Login login) {
Log.e("-----",""+login.getUserId());
}
#Override
protected void resolveDaggerDependency() {
DaggerLoginComponent.builder().applicationComponent(getApplicationComponent()).loginModule(new LoginModule(this)).build().inject(this);
}
}
Here is Login Presenter :
public class LoginPresenter extends BasePresenter<LoginView> implements Observer<Login>{
#Inject
CreateApiService createApiService;
#Inject
public LoginPresenter(){};
public void passLoginDataToServer(){
/*
when i hard code the data , i get the successful response.Like :
String user="raj";
String check="true";
Map<String,String> headers=new HashMap();
headers,put("xyz","pqr");
Login loginObject = new Login("xyzs", "pqr","Qtch","mvp");
*/
/*
But I need the data here from my LoginActivity ? Dunno how to pass the data from LoginActivity to presenter
*/
Observable<Login> loginObservable=createApiService.loginUser(user, check, headers, loginObject);
subscribeToLogin(loginObservable,this);
}
#Override
public void onSubscribe(Disposable d) {
}
#Override
public void onNext(Login login) {
getmView().onResponse(login);
}
#Override
public void onError(Throwable e) {
getmView().onError("Error "+e);
Log.e("---",""+e);
}
#Override
public void onComplete() {
getmView().onSuccess("Successfully Loaded");
}
}
Here is My Interface :
public interface LoginView extends BaseView {
void onError(String s);
void onSuccess(String s);
void onResponse(Login login);
}
Could you add the parameters to the method?
In your activity:
#Override public void onClick(View view) {
String company=companyName_et.getText().toString();
String username=email_et.getText().toString();
String password=password_et.getText().toString();
loginPresenter.passLoginDataToServer(compay, username, password);
}
In your presenter:
public void passLoginDataToServer(String company, String username, String password){
// Now create your request from the dynamic parameters
Observable<Login> loginObservable=createApiService.loginUser(username, check, headers, loginObject);
subscribeToLogin(loginObservable,this);
}
I take reference from official website https://quickblox.com/developers/Android#Download_Android_SDK
gradle compile succeed:
repositories {
maven {
url "https://github.com/QuickBlox/quickblox-android-sdk-releases/raw/master/"
}
}
dependencies {
compile "com.quickblox:quickblox-android-sdk-core:2.5.1#aar"
compile("com.quickblox:quickblox-android-sdk-chat:2.5.1#aar") {
transitive=true
}
}
then i use the code first:
I had the APP_ID...etc
QBSettings.getInstance().init(getApplicationContext(), APP_ID, AUTH_KEY, AUTH_SECRET);
QBSettings.getInstance().setAccountKey(ACCOUNT_KEY);
Second step :
I reference Guide: Getting Started with Chat API https://quickblox.com/developers/Android_XMPP_Chat_Sample#Guide:_Getting_Started_with_Chat_API
//Prepare chat service
QBChatService.setDebugEnabled(true); // enable chat logging
QBChatService.setDefaultPacketReplyTimeout(10000);//set reply timeout in milliseconds for connection's packet.
//Can be used for events like login, join to dialog to increase waiting response time from server if network is slow.
//configure chat socket
QBChatService.ConfigurationBuilder chatServiceConfigurationBuilder = new QBChatService.ConfigurationBuilder();
chatServiceConfigurationBuilder.setSocketTimeout(60); //Sets chat socket's read timeout in seconds
chatServiceConfigurationBuilder.setKeepAlive(true); //Sets connection socket's keepAlive option.
chatServiceConfigurationBuilder.setUseTls(true); //Sets the TLS security mode used when making the connection. By default TLS is disabled.
QBChatService.setConfigurationBuilder(chatServiceConfigurationBuilder);
It has a issue that i can't import QBChatService.ConfigurationBuilder
so i try to change gradle to compile("com.quickblox:quickblox-android-sdk-chat:2.6.1")
now QBChatService.ConfigurationBuilder can be import
Third step:
I take the official step use the code:
// Initialise Chat service
final QBChatService chatService = QBChatService.getInstance();
final QBUser user = new QBUser("garrysantos", "garrysantospass");
QBAuth.createSession(user, new QBEntityCallback<QBSession>() {
#Override
public void onSuccess(QBSession qbSession, Bundle bundle) {
// success, login to chat
user.setId(qbSession.getUserId());
chatService.login(user, new QBEntityCallback() {
#Override
public void onSuccess(Object o, Bundle bundle) {
}
#Override
public void onError(QBResponseException e) {
}
});
}
#Override
public void onError(QBResponseException e) {
}
});
//To handle different connection states use ConnectionListener:
ConnectionListener connectionListener = new ConnectionListener() {
#Override
public void connected(XMPPConnection xmppConnection) {
}
#Override
public void authenticated(XMPPConnection xmppConnection, boolean b) {
}
#Override
public void connectionClosed() {
}
#Override
public void connectionClosedOnError(Exception e) {
// connection closed on error. It will be established soon
}
#Override
public void reconnectionSuccessful() {
}
#Override
public void reconnectingIn(int i) {
}
#Override
public void reconnectionFailed(Exception e) {
}
};
QBChatService.getInstance().addConnectionListener(connectionListener);
//logOut
boolean isLoggedIn = chatService.isLoggedIn();
if (!isLoggedIn) {
return;
}
chatService.logout(new QBEntityCallback<Void>() {
#Override
public void onSuccess(Void aVoid, Bundle bundle) {
//success
chatService.destroy();
}
#Override
public void onError(QBResponseException e) {
}
});
//By default Android SDK reconnects automatically when connection to server is lost.
//But there is a way to disable this and then manage this manually:
QBChatService.getInstance().setReconnectionAllowed(false);
when i use the step about QBChatDialog , it can't be import again....
ArrayList<Integer> occupantIdsList = new ArrayList<Integer>();
occupantIdsList.add(34);
occupantIdsList.add(17);
QBChatDialog dialog = new QBChatDialog();
dialog.setName("Chat with Garry and John");
dialog.setPhoto("1786");
dialog.setType(QBDialogType.GROUP);
dialog.setOccupantsIds(occupantIdsList);
//or just use DialogUtils
//for creating PRIVATE dialog
//QBChatDialog dialog = DialogUtils.buildPrivateDialog(recipientId);
//for creating GROUP dialog
QBChatDialog dialog = DialogUtils.buildDialog("Chat with Garry and John", QBDialogType.GROUP, occupantIdsList);
QBRestChatService.createChatDialog(dialog).performAsync(new QBEntityCallback<QBChatDialog>() {
#Override
public void onSuccess(QBChatDialog result, Bundle params) {
}
#Override
public void onError(QBResponseException responseException) {
}
});
so i try to change gradle compile compile("com.quickblox:quickblox-android-sdk-chat:3.3.0")
now QBChatDialog can be imported.
but it has another issues...
Can't not resolve symbol 'QBSettings' and 'QBSession'
I'm angry now , are you kidding me ?
Why the official step cheat me step by step ?
I'm tired... what should i do ?
Somebody can save me please , any help would be appreciated !
According #Jagapathi kindly responding , i update my code , the next issue is that i can't log in
My toast shows Login error when i click the login button:
private void setupQuickBlox() {
QBSettings.getInstance().init(getApplicationContext(), APP_ID, AUTH_KEY, AUTH_SECRET);
QBSettings.getInstance().setAccountKey(ACCOUNT_KEY);
QBSettings.getInstance().setAutoCreateSession(true);
//login to quickblox
String enterAccount = editAccount.getText().toString();
String enterPassword = editPassword.getText().toString();
Log.d(TAG,enterAccount);
Log.d(TAG,enterPassword);
final QBUser user = new QBUser(enterAccount, enterPassword);
//login
QBUsers.signIn(user).performAsync(new QBEntityCallback<QBUser>() {
#Override
public void onSuccess(QBUser qbUser, Bundle bundle) {
SharedPreferences.Editor s = getSharedPreferences("QBid", 0).edit();
s.putString("id", user.getId().toString());
s.apply();
Log.d(TAG,user.getId().toString());
Toast.makeText(MainActivity.this, "Login success with quickblox", Toast.LENGTH_SHORT).show();
}
#Override
public void onError(QBResponseException e) {
Toast.makeText(MainActivity.this, "Login error", Toast.LENGTH_SHORT).show();
}
});
}
the code is under my onCreat , so it shows Login error when i satrt the app of course , but when i enter account and password , it still shows Login error , why? I check the log , i can see the account and password that i typed , but i can't see user.getId().toString() on my log , what step is wrong ?
i check the account is correct:
Here is my key:
static final String APP_ID = "50427";
static final String AUTH_KEY = "naMGFKMshdLC3s4";
static final String AUTH_SECRET = "GP8ey4GsQXt2TGu";
static final String ACCOUNT_KEY = "dHYgix3we3bxxsvMqyuR";
Here is my test Account key:
My button onClcik:
buttonLogin.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
setupQuickBlox();
}
});
Here is my log:
I can guide you with Quickblox I am in same position when I started using quickblox.
step 1:-
compile 'com.quickblox:quickblox-android-sdk-core:3.3.0#aar'
compile("com.quickblox:quickblox-android-sdk-chat:3.3.0#aar") {
transitive = true
}
This is for latest version of quickblox. So don't use old versions .
step 2:-
This is my SetUp Quickblox function you don't forgot to use app_id Auth_key auth_secret and account_key
private void SetupQuickBlox() {
QBSettings.getInstance().init(getApplicationContext(), APP_ID, AUTH_KEY, AUTH_SECRET);
QBSettings.getInstance().setAccountKey(ACCOUNT_KEY);
QBSettings.getInstance().setAutoCreateSession(true);
//login to quickblog for
final QBUser user=new QBUser("USER_NAME OF USER","PASSWORD OF USER");
// Login
QBUsers.signIn(user).performAsync(new QBEntityCallback<QBUser>() {
#Override
public void onSuccess(QBUser user, Bundle args) {
// success
SharedPreferences.Editor s=getSharedPreferences("QBid",0).edit();
s.putString("id",user.getId().toString());
s.apply();
Toast.makeText(HomeActivity.this, "Login succes with quickblox", Toast.LENGTH_SHORT).show();
}
#Override
public void onError(QBResponseException error) {
// error
}
});
}
step:- 3
You are all done Login with quickblox is successful so you can now request DIALOGS or CREATE DIALOg Sessions are automatically created in latest version.
Create New Dialog
private void NewMessage() {
FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
fab.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
QBChatDialog dialog = DialogUtils.buildPrivateDialog("USER_ID of other user");
dialog.setName("tester1");
QBRestChatService.createChatDialog(dialog).performAsync(new QBEntityCallback<QBChatDialog>() {
#Override
public void onSuccess(QBChatDialog result, Bundle params) {
}
#Override
public void onError(QBResponseException responseException) {
}
});
}
});
}
Request List Of Dialog Of Logged In User
I Used ListView And Dialogs result will be in array list which contains LIST of QBCHATDIALOG
private void receiveChatList() {
QBRequestGetBuilder requestBuilder = new QBRequestGetBuilder();
requestBuilder.setLimit(100);
QBRestChatService.getChatDialogs(null, requestBuilder).performAsync(
new QBEntityCallback<ArrayList<QBChatDialog>>() {
#Override
public void onSuccess(final ArrayList<QBChatDialog> result, Bundle params) {
int totalEntries = params.getInt("total_entries");
Log.wtf("chat",""+result);
TrumeMsgAdapter adapter=new TrumeMsgAdapter(TrueMeMessagesActivity.this,result);
chatlistView.setAdapter(adapter);
chatlistView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
startActivity(new Intent(TrueMeMessagesActivity.this,ChatingActivity.class).putExtra("dialog",result.get(position)));
}
});
}
#Override
public void onError(QBResponseException responseException) {
}
});
}
My Adapter Code
public class TrumeMsgAdapter extends BaseAdapter {
private ArrayList<QBChatDialog> chatlist;
private Context context;
public TrumeMsgAdapter(Context c,ArrayList<QBChatDialog> chatlist){
this.chatlist=chatlist;
this.context=c;
}
#Override
public int getCount() {
return chatlist.size();
}
#Override
public Object getItem(int position) {
return null;
}
#Override
public long getItemId(int position) {
return 0;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View List;
LayoutInflater inflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
if (convertView == null) {
List = inflater.inflate(R.layout.trume_msg_adapter, null);
TextView username=(TextView) List.findViewById(R.id.UserName);
TextView lastmessage=(TextView)List.findViewById(R.id.lastmessage);
username.setText(chatlist.get(position).getName());
lastmessage.setText(chatlist.get(position).getLastMessage());
} else {
List = convertView;
TextView username=(TextView) List.findViewById(R.id.UserName);
TextView lastmessage=(TextView)List.findViewById(R.id.lastmessage);
username.setText(chatlist.get(position).getName());
lastmessage.setText(chatlist.get(position).getLastMessage());
}
return List;
}
}
I've had an interview and I was given the following code, so that the UserAPI is a utility class for retrieving data from the network.
Assume it operate with its own threading mechanism with no respect to the caller thread.
And I had to find what's wrong with the code:
public class NetworkTestActvitiy extends Activity {
private TextView userNameTextView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.chegg_test_layout);
userNameTextView = (TextView)findViewById(R.id.userName);
}
#Override
protected void onStart() {
super.onStart();
loadUserName();
}
private void loadUserName() {
UserAPI.getInstance().getUserName(new NetworkListener() {
#Override
public void onError(ErrorMessage error) {
Logger.e("Failed to get user use: " + error.getMessage());
}
#Override
public void onSuccess(String userName) {
userNameTextView.setText(userName);
}
});
}
}
My guess would be that the call to userNameTextView.setText can not be from UI thread and has to be marshalled.
In one of my project, I am using loopj asynchttpclient for communicating with my website.
The communication part working well and getting response as well
My activity looks like
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_home);
WebRequest test=new WebRequest();
test.callService();
}
WebRequest Class as
public class WebRequest extends Activity {
public void callService(){
AsyncHttpClient client = new AsyncHttpClient();
client.post("http://domain.com/dp/index.php", new AsyncHttpResponseHandler() {
#Override
public void onSuccess(String response) {
Log.v("P",response);
}
#Override
public void onFailure(Throwable e, String response) {
Log.v("PS",e.toString());
}
});
}
}
I am confused how to return the response to the main activity, So that I can create the listview from that response.
I am new to this
Please help me
Thanks in advance
In your WebRequest class:
I don't think you want this class to extend Activity. You should only extend Activity when you're making a page to display in your app. You just want to execute some code, so extending Activity isn't needed.
Change your call service method to be static and take an AsyncHttpClient as a parameter.
Your WebRequest class should now look like this:
final class WebRequest {
private AsyncHttpClient mClient = new AsyncHttpClient();
public static void callService(AsyncHttpResponseHandler handler) {
mClient.post("http://domain.com/dp/index.php", handler);
}
}
In your main Activity:
Now all you have to do in your main activity is call the static method like this:
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_home);
WebRequest.callService(new AsyncHttpResponseHandler() {
#Override
public void onStart() {
// Initiated the request
}
#Override
public void onSuccess(String response) {
// Successfully got a response
}
#Override
public void onFailure(Throwable e, String response) {
// Response failed :(
}
#Override
public void onFinish() {
// Completed the request (either success or failure)
}
});
}
Do whatever you need to do with the Views in your activity in the above callbacks. Hope this Helps!
