I start to work with volley and when i try to make a post request it give me only errore.
Can you guys tell me when im wrong?
Im working on the Android side of the project with VolleyLibrary.
public class MainActivity extends AppCompatActivity {
private EditText etUsername;
private EditText etPassword;
private Button btnLogin;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
etUsername = findViewById(R.id.etUsername);
etPassword = findViewById(R.id.etPassword);
btnLogin = findViewById(R.id.btnLogin);
btnLogin.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Login();
}
});
}
private void Login(){
String url = "http://myapies.youcantwatch.it/loginuser_module";
RequestQueue requestQueue = Volley.newRequestQueue(this);
StringRequest stringRequest = new StringRequest(Request.Method.POST, url, new Response.Listener<String>() {
#Override
public void onResponse(String response) {
if(!response.trim().equals("errors")){
Intent intent = new Intent(MainActivity.this, LoggedActivity.class);
startActivity(intent);
} else {
Toast.makeText(MainActivity.this, "Login Fallito", Toast.LENGTH_SHORT).show();
}
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Toast.makeText(MainActivity.this, "La chiamata non รจ andata a buon fine", Toast.LENGTH_SHORT).show();
}
}) {
#Override
protected Map<String, String> getParams() throws AuthFailureError {
Map<String, String> params = new HashMap<>();
params.put("firstName","adkdmadm");
params.put("password","asdasdjn");
params.put("secretKey","dlwdmkemd3d455");
params.put("username", etUsername.getText().toString().trim());
params.put("passwordasdad", etPassword.getText().toString().trim());
return super.getParams();
}
};
requestQueue.add(stringRequest);
}
}
Replace StringRequest->JSONObjectRequest and check.
Pass request parameters in JSONObject, not in the header,
only pass Content-Type->application/json in header.
change volley to another libs like retrofit volley long time not updated

try changing your Content-Type
application/json;charset=utf-8
to
application/json
I started learning Android and Java a week ago and now I am trying to make an login application. I am using Volley libary to communicate with my server. I have done the login part. Now, what I want to do is to check the database every minute to see if the password or the username somehow changed. If the information in the database is changed, app will automaticly logout the user.
If you can explain which tools(Services,BroadcastReceivers) I can use and how can I achieve it, as I am not very experienced.
This is what I tried and failed:
loginChecker.class
public class loginChecker extends Service {
public loginChecker() {
}
public static String username;
public static String password;
private loginChecker mInstance = this;
public static boolean loginCheck= true;
public static String responseG = "failed";
#Override
public int onStartCommand(Intent intent, int flags, int startId) {
Bundle b=intent.getExtras();
username = b.getString("username");
password = b.getString("password");
final String URL = ".........";
final RequestQueue requestQueue = Volley.newRequestQueue(mInstance);
new Thread(new Runnable(){
public void run() {
do{
try {
Thread.sleep(10000);
} catch (InterruptedException e) {
e.printStackTrace();
}
StringRequest request = new StringRequest(Request.Method.POST, URL, new Response.Listener<String>() {
#Override
public void onResponse(String response) {
responseG = response;
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
responseG = "error";
}
}) {
#Override
protected Map<String, String> getParams() throws AuthFailureError {
HashMap<String, String> hashMap = new HashMap<String, String>();
hashMap.put("username", username);
hashMap.put("password", password);
return hashMap;
}
};
requestQueue.add(request);
switch(responseG){
case "successful" :
loginCheck = true;
break;
case "failed" :
loginCheck= false;
break;
case "error" :
loginCheck = false;
break;
}
}
while(loginCheck == true || responseG == "successful");
}
}).start();

Bundle b = new Bundle();
b.putString("username", String.valueOf(userName.getText()));
b.putString("password", String.valueOf(passWord.getText()));
loginCheckerService.putExtras(b);
startService(loginCheckerService);
startActivity(profilePage);
finish();
break;
case "failed" :
Toast.makeText(getApplicationContext(), "Username or Password you entered is wrong!", Toast.LENGTH_LONG).show();

You are not initialazing the "editTextMessages", this is your null pointer exception.
all.
I am using volley to make a http request to my website server. And it works fine and response when click the commit button to add a request to request queue. But click the button again does not response. It still shows the progressdialog and response nothing. Is there something wrong ?
Here's code example below:
public class MainActivity extends ActionBarActivity {
private static final String URL = "http://www.google.com";
public RequestQueue mQueue = null;
public StringRequest request = null;
private Button mScanButton = null;
private TextView mDisplay = null;
private ProgressDialog dialog = null;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mScanButton = (Button) findViewById(R.id.button_scan);
mDisplay = (TextView) findViewById(R.id.display);
request = new StringRequest(Request.Method.GET, URL,
new Response.Listener<String>() {
#Override
public void onResponse(String response) {
System.out.println("Response retrieved");
mDisplay.setText(response);
dialog.dismiss();
}
},
new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
mDisplay.setText("That didn't work.");
dialog.dismiss();
}
});
request.setShouldCache(false);
mScanButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
dialog = ProgressDialog.show(MainActivity.this, "Mapping data", "please wait..");
mQueue = Volley.newRequestQueue(MainActivity.this);
mQueue.add(request);
System.out.println("Add to queue..");
}
});
}
try this May this guide you here is the complete source which helps you understand easily.
looking at this line
if (ServerConfig.isNetworkOnline(SplashScreen.this)) {
StringRequest strReq = new StringRequest(Request.Method.POST, "your server link", serverResponse, errorListener) {
};
AppController.getInstance().getRequestQueue().add(strReq);
} else {
Toast.makeText(getApplicationContext(), "Please check your network connection", Toast.LENGTH_SHORT).show();
finish();
}
you can remove those above code leaving with below code.
StringRequest strReq = new StringRequest(Request.Method.POST, "your server link", serverResponse, errorListener) {
};
AppController.getInstance().getRequestQueue().add(strReq);
I try to move the area of request declaration to on-click method and it works fine. But I still don't understand how it works.
public class MainActivity extends ActionBarActivity {
private static final String URL = "http://www.google.com";
public RequestQueue mQueue = null;
public StringRequest request = null;
private Button mScanButton = null;
private TextView mDisplay = null;
private ProgressDialog dialog = null;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mScanButton = (Button) findViewById(R.id.button_scan);
mDisplay = (TextView) findViewById(R.id.display);
mScanButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
dialog = ProgressDialog.show(MainActivity.this, "Mapping data", "please wait..");
request = new StringRequest(Request.Method.GET, URL,
new Response.Listener<String>() {
#Override
public void onResponse(String response) {
System.out.println("Response retrieved");
mDisplay.setText(response);
dialog.dismiss();
}
},
new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
mDisplay.setText("That didn't work.");
dialog.dismiss();
}
});
mQueue = Volley.newRequestQueue(MainActivity.this);
mQueue.add(request);
System.out.println("Add to queue..");
}
});
}
