So i´m trying to login on my app and when i click the login button after inserting the username and password this error shows up in the android studio at the run tab on the bottom toolbar in the left corner:

with my site link and nothing more.

If you need more classes or the android manifest comment below and i edit the post.
I already have the login.php to connect to the database at the file manager and everything.
If you can help me understanding why this error is showing up i would be gratefull.
HTTP code 301 means "moved permanently". This means the URL you're trying to reach is no longer there. I had the same problem when my site implemented SSL. They redirected all request from http:// to https:// using an .htaccess file in the server, so the address in the Android app had to be changed accordingly, since it's not going to accept the redirection. You should change your LOGIN_REQUEST_URL variable to:
private static final String LOGIN_REQUEST_URL = "https://elabora.pt/login.php";
Hope this helps (it did solve my problem, though)
I had the same problem. Unexpected response code 301
I was using https://example.com but it was redirecting to https://www.example.com via .htaccess
Changing to https://www.example.com in the app code solved my problem.
Try to open the url in the browser here you can see the exactly redirected URL copy this to your code.
You can specify a http folder in your host or sever instead of auto redirect to https when you use volley.
It seems Volley can not handle https request.

i'm very beginner in this problem.
i following the tutorials from youtube make a database for user register, i use localhost and put the php file into htdocs and it's succes but when i tried to put the php file into 000webhost file manager. the result is 'something went wrong' it should be 'Succesfully Registered'. i dont know what should i do because there's no error in logcat. i'm sure there's no error in php file because i've matched it with the real source code.

While Installing app is not asking for internet permissions though I mentioned it in manifest file.

You need to add your request object to the Volley queue (in your case, mQueue) in order for the request to be executed.
Example:
mQueue.add(request);
Internet permission is normal permission so the android system will not ask internet permission.
You just call this line:
mQueue.add(request);
end of the request.
Add below line after errorListener method at end of your request
mQueue.add("your request type");
I have tried a lot of codes and techniques. But i could not find any solution. I also posted my problem on stackover flow but could not get any response. Thats why i am again posting this question.
I am new to android. I have a website which in now running online with secure SSL certificate. I have designed an android app where people will perform their registration.

How can we pass params from editText to url using request.GET method.
Actually I am trying to pass an email address as parameter to a api which should b attached to api-url .
I came to know from here that getParams() is not called on the GET method, so it seems you'll have to add it to the URL before you send the request.
suggest me any solution to achieve the task ..
when i pass REG_URL="http://ec2-54-147-238-136.compute-1.amazonaws.com/hmc/api/registeruser?email=ameer#novatoresols.com";
it return success=true response as expected because is registered user
but if i set REG_URL="http://ec2-54-147-238-136.compute-1.amazonaws.com/hmc/api/registeruser and pass the params (get value from edittext and use params.put in getparams() method ).response is always success=false i.e params is not attached to url

As suggested by #Puneet worked for me which is as :
getParams is only called for POST requests. GET requests don't have a body and hence, getParams is never called. For a simple request like yours just add the parameters to your URL and use that constructed URL to make that request to your server (REG_URL + "?email=" + email).
To pass the parameters, you need to create a class for the key-value pairs.
1) Create a class KeyValuePair with two fields key and value with appropriate constructor and getter-setter methods.
2) Now, for each parameter, you need to create an object of this class, i.e., for a key username with value user#gmail.com, the object would be new KeyValuePair("username", "user#gmail.com").
3) Now, you need to create a List to store these parameters and pass this list to the below method with your base url,
public static String generateUrl(String baseUrl, List<KeyValuePair> params) {
if (params.size() > 0) {
for (KeyValuePair parameter: params) {
if (parameter.getKey().trim().length() > 0)
baseUrl += "&" + parameter.getKey() + "=" + parameter.getValue();
}
}
return baseUrl;
}
4) Pass this baseUrl to your Request.
Actually i want to post on my page as a page not as a user using facebook sdk in android app but the problem is page "AccessToken" which i retrieve from graph request is in String and now i cannot use it in an other graph request. it says String cannot converted to AccessToken.
Here is my code.
package com.mak.masimmak.pageshare;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.Toast;

import org.json.JSONException;
import org.json.JSONObject;
public class sharePage extends AppCompatActivity {
Button shareButton;
public String PageId;
String PageAccessToken;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_share_page);
shareButton = (Button) findViewById(R.id.shareButton);
shareButton.setOnClickListener(new View.OnClickListener(){
#Override
public void onClick(View view) {
if(getIntent().getExtras() != null) {
Bundle extras = getIntent().getExtras();
PageId = extras.getString("PageId");
/* make the API call */
new GraphRequest(
AccessToken.getCurrentAccessToken(),
"/"+PageId+"?fields=access_token",
null,
HttpMethod.GET,
new GraphRequest.Callback() {
public void onCompleted(GraphResponse response) {
/* handle the result */
try {
JSONObject data = response.getJSONObject();
PageAccessToken = data.getString("access_token");
PostOnPage();
} catch (JSONException e) {
Toast.makeText(sharePage.this, e.toString(), Toast.LENGTH_LONG).show();
}
}
}
).executeAsync();
}
}
});
}
public void PostOnPage(){
Bundle params = new Bundle();
params.putString("message", "This is a test message");
/* make the API call */
new GraphRequest(
/* Problem is here the PageAccessToken is in String How to use this string token here? */
(AccessToken) PageAccessToken,
"/"+PageId+"/feed",
params,
HttpMethod.POST,
new GraphRequest.Callback() {
public void onCompleted(GraphResponse response) {
/* handle the result */
}
}
).executeAsync();
}
}
I search the problem in google and i found something..
public AccessToken(String accessToken, String applicationId, String userId, Collection permissions, Collection declinedPermissions, AccessTokenSource accessTokenSource, Date expirationTime, Date lastRefreshTime)
But i don't know how use this or implement this in my code.
I found the solution of my own question.
You can convert AccessToken from String format to Facebook AccessToken format using this line of code.
AccessToken PageAT = new AccessToken(PageAccessToken, AccessToken.getCurrentAccessToken().getApplicationId(), AccessToken.getCurrentAccessToken().getUserId(), AccessToken.getCurrentAccessToken().getPermissions(), null, AccessTokenSource.FACEBOOK_APPLICATION_NATIVE, AccessToken.getCurrentAccessToken().getExpires(), null);
Then this PageAT will work fine in your new Graph Request..
