I don't know anything about coding and have been learning as I go along
i cant seem to log in via google even though I do show up as active on firebase
can anyone see if I'm missing something?
//Relate to google login
private void handleSignInResult(Task<GoogleSignInAccount> completedTask) {

} else {

}

if (lname.equals("") || lname.equals("null"))

}
} catch (ApiException e) {

}
}
public void Change_Url_to_base64(final String user_id,

Log.d(Variables.tag, picture);
if (picture.equalsIgnoreCase("null")) {
Call_Api_For_Signup(user_id, f_name, l_name, picture, singnup_type);
} else {
Glide.with(this)
.asBitmap()
.load(picture)
.into(new CustomTarget<Bitmap>() {
#Override

}
#Override

I'm only righting this part because the website keeps telling me that its mostly code and i need to add more details even though i dont know what else to ask or add

**This is jazz.net' offical sample code. My question is how can I set value to "categoryName" in "private static boolean run(String[] args) throws TeamRepositoryException" function.In the Main fuction,there is nothing describing the "arg[]".Who can give me a sample to initial "categoryName" argument. **
The category name argument is something that is defined in the RTC CCM project against the timeline or the project. A sample for this is shown below.
These are the values that are expected in the Category Name Argument.
You can look into your project settings to get this information.
Before adding viewmodel & livedata , i successfully implemented infinity scroll with retrofit. But after adding viewmodel & livedata with Retrofit, My can't update recyclerview with new data call or viewmodel observer not update the list.
I simply want to infinite scrolling as my code does before. I add a global variable to reuse next page token. Am i missing anything or any sample to implement infinite recyclerview with viewmodel & retrofit will be awesome.
public static String NEXT_PAGE_URL = null;
I coded like that.

I precise code due to question simplicity.
Though you already use android-jetpack, take a look at Paging library. It's specially designed for building infinite lists using RecyclerView.
Based on your source code, I'd say that you need PageKeyedDataSource, here is some example which includes info about how to implement PageKeyedDataSource -
7 steps to implement Paging library in Android
If talking about cons of this approach:
You don't need anymore to observe list scrolling (library doing it for you), you just need to specify your page size in the next way:
PagedList.Config myPagingConfig = new PagedList.Config.Builder()
.setPageSize(50)
.build();
From documentation:
Page size: The number of items in each page.
Your code will be more clear, you'll get rid of your RecyclerView.OnScrollListener
ViewModel code will be shorter, it's will provide only PagedList:
#NonNull
LiveData<PagedList<ReviewSection>> getReviewsLiveData() {
return reviewsLiveData;
}
I work with liferay-5.2.3 and I integrated LDAP
using this configuration :
in portal-ext.properties I make this lines :
ldap.import.method=group
system.community.roles=TestGr
and in liferay I make this configuration :
I activated the authentication using ldap .
I created two groups in LDAP :
TestGroup1 and TestGroup2
User import is periodic every hour As shown in the configuration
I tried to create Four users in ldap :
user1 under testGroup1
user2 under testGroup2
user3 , user4 out of the two previous groups
Import of users is done correctly : only user1 and user2 will be create in the database of liferay .
The problem is when I tried to authenticate with user3
I found that the user3 is created in the liferay database
Despite the fact that the user3 does not exist in the two groups TestGroup1 and TestGroup2
I think that the solution is to disable import users from ldap after login or also check existing users in some groups before the import ( Which exists in the configuration ).
Updated :
this is the code of LDAPAuth class :

(i'm just having my experiment)
what I want is to run activity B while foreground is in activity A, just like a basic OOP . but my problem is, I don't know how to make it run. I can't also jump to activity B since it has an oncreate method. I instantiated it and can get the variables values but they are null (seems there is no process happened) . What can be a best solution for this.
note: I am currently looking how to use service for background processing but also i don't know how to run this code after I typed it from a tutorial :( there is only a tutorial for creating a service part but no tutorial for buttons to access it :(
using System;
using Android.App;
using Android.Content;
using Android.OS;
using Android.Util;
using System.Threading;
namespace LocatorApp
{
[Service]
class SimpleService : Service
{
static readonly string TAG = "X:" + typeof(SimpleService).Name;
static readonly int TimerWait = 4000;
Timer _timer;
public override StartCommandResult OnStartCommand(Intent intent, StartCommandFlags flags, int startId)
{
Log.Debug(TAG, "OnStartCommand called at {2}, flags={0}, startid={1}", flags, startId, DateTime.UtcNow);
_timer = new Timer(o => { Log.Debug(TAG, "Hello from SimpleService. {0}", DateTime.UtcNow); },
null,
0,
TimerWait);
return StartCommandResult.NotSticky;
}
public override void OnDestroy()
{
base.OnDestroy();
_timer.Dispose();
_timer = null;
Log.Debug(TAG, "SimpleService destroyed at {0}.", DateTime.UtcNow);
}
public override IBinder OnBind(Intent intent)
{
// This example isn't of a bound service, so we just return NULL.
return null;
}
}
}
I want to know both (OOP way and service way) since not at all time we are required to use the service.
what I want is to run activity B while foreground is in activity A, just like a basic OOP . but my problem is, I don't know how to make it run. I can't also jump to activity B since it has an oncreate method.
You can call Context.StartActivity inside your Activity with following codes:
StartActivity(new Android.Content.Intent(this, typeof(ActivityB)));
And StartActivity will call OnCreate method in ActivityB to create a new instance of ActivityB.
For details about Starting Activities, please refer to Starting Activities and Getting Results.
I am currently looking how to use service for background processing but also i don't know how to run this code after I typed it from a tutorial :( there is only a tutorial for creating a service part but no tutorial for buttons to access it :(
Similar like Activity Context.StartService offers a way to start a Service:
StartService (new Intent (this, typeof(DemoService)));
This will call the OnStartCommand method inside your Service class.
For details about usage of Service, please refer to Implementing a Service.
I am making the authentication of my android application, I want to send the entered password & email in json format then my web service is going to test if they are correct then it will return the result in json format also.
But before doing this, I want to make a mock function that replace my webservice and do this just to test before .
Here is the code
After making the validation of interface(Email & password are valid )
mock class
if(fault==false)
//new AttemptLogin().execute();
new GetUser().execute();
My class GetUser is here (the mock class that will replace my web service )
private class GetUser extends AsyncTask<Void, Void, Void> {
#Override
protected void onPreExecute() {
super.onPreExecute();
// Showing progress dialog
pDialog = new ProgressDialog(MainActivity.this);
pDialog.setMessage("Please wait...");
pDialog.setCancelable(false);
pDialog.show();
}
#Override
protected Void doInBackground(Void... arg0) {
String e2=email.getText().toString();
String p2=password.getText().toString();
if (e2 != null && p2!=null) {
try {
JSONObject jsonObj1 = new JSONObject(e2);
JSONObject jsonObj2 =new JSONObject(p2);
UserEmail=jsonObj1.getJSONObject(TAG_Email);
UserPassword=jsonObj2.getJSONObject(TAG_Password);
Toast.makeText(getApplicationContext(),"hi",
Toast.LENGTH_LONG).show();
String c=checkLogin(UserEmail, UserPassword);
Toast.makeText(getApplicationContext(),c,
Toast.LENGTH_LONG).show();
} catch (JSONException e) {
e.printStackTrace();
}
} else {
Log.e("ServiceHandler", "Couldn't get any data from the url");
}
return null;
}
protected void onPostExecute(String result) {
// dismiss the dialog once product deleted
if (pDialog.isShowing())
pDialog.dismiss();
if (result != null){
Toast.makeText(MainActivity.this, result, Toast.LENGTH_LONG).show();
}
And this is the method checkLogin that check if the user has logged with the right email & password .
protected String checkLogin(JSONObject UserEmail,JSONObject UserPassword) {
String e ;
String p;
String r="";
try {
e= UserEmail.getString(TAG_Email);
p = UserPassword.getString(TAG_Password);
if (e.equals("exemple.android#yahoo.fr") &&
p.equals("123456")) {
Toast.makeText(getApplicationContext(), "Hello imene!",
Toast.LENGTH_SHORT).show();
r="ok";
} else {
Toast.makeText(getApplicationContext(), "Seems like you 're not imene!",
Toast.LENGTH_LONG).show();
numberOfRemainingLoginAttempts--;
Toast.makeText(getApplicationContext(), "number of Remaining login Attemts ="+numberOfRemainingLoginAttempts,
Toast.LENGTH_LONG).show();
if (numberOfRemainingLoginAttempts == 0) {
validate.setEnabled(false);
Toast.makeText(getApplicationContext(), "Login Locked!",
Toast.LENGTH_LONG).show();
r="ko";
}
}
} catch (JSONException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
return r;
}`
But ,i don't have any result .Can any one tell me where is the problem in my code .
