When i click on the button, the ListView opens but with no data i.e. Empty set.
Contacts_View.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<ListView
android:id="#android:id/list"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
/>
<TextView android:id="#android:id/empty"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Empty set"
/>
</LinearLayout>
What i mean here is that both the functions are identical.getGPosts() is called in the FBAppActivity whereas the createAdapter() is called in MessagesActivity.getGPosts() works but createAdapter() does not. Kindly help me understand why is this happening.
Basically i am trying to import posts from a facebook group. My Toast object is working fine from the getGPosts() [it is in the FBAppActivity class] function. This function getGPosts() is called on the button click.I verified that i am getting the data using the Toast object. Now i want to populate the data to a ListView. Which i am unable to do. I have tried various methods, but none has worked out for me.

Because you're calling the setListAdapter(adapter) for implicit (Activity's) ListView in the onCreate(Bundle savedInstanceState) method and in the getGPosts() method you reference the correct (visible) ListView.
Simply change the mentioned call in the onCreate(Bundle savedInstanceState) method to:
myListView = getListView();
myListView.setAdapter(adapter);
And you should be fine! Good luck!
P.S. This solution will work if your ListActivity follows the following requirement:
your own view MUST contain a ListView object with the id "#android:id/list"
from Google's documentation

As I see you are extending ListActivity. So below code must throw a NPE.
lv = (ListView)findViewById(R.id.list);
lv.setAdapter(adapter);
You should use below code at onComplete method instead;
setListAdapter(adapter);
or
getListView().setAdapter(adapter);

Please If you have a solution or an example to do it help me.
Thank you.

Make sure you have done below steps for establishing WebRTC peer to peer connection.
Add native libraries - libjingle_peerconnection_so.so files. Put native library for each platform: arm64-v8a, armeabi-v7a, x86, x86_64 under app/src/main/jniLibs folder. You can find native files in sample under /src/main/jniLibs folder.
Check the DOC for screenshots.

Adding onClick to RecyclerView Android [duplicate]

This question already has answers here:
RecyclerView Single Item ID
(2 answers)
Closed 5 years ago.
I have put together some code as shown below which gets data from a JSON file hosted on a server and puts it into a RecyclcerView. This has been working fine but any way I try to add a click method it does not work. I am looking to make it so that if I click one of the rows it will tell me the country it is. I have no idea where I am going wrong but I will attach my code below which gets the JSON data and puts it into the RecyclerView.
Thanks

Instead of adding a click listener on the Recycler view, try adding click listener in the adapter class, in the onBindViewHolder method. That is how you will get the exact item on which the click was executed.
#Override
public void onBindViewHolder(Viewholder holder, final int position) {
YourClassObject item = YourClassObjectList.get(position);
holder.itemView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Toast.makeText(view.getContext(), "Recycle Click" + position, Toast.LENGTH_SHORT).show();
}
});

Create a interface in your Adapter class
public interface EventsCatalogsAdapter{
void onClickImageCategory(Catalogs catalog);
}
Create a atribute of EventsCatalogsAdapter
private EventsCatalogsAdapter event;
Create constructor
public CatalogsAdapter(EventsCatalogsAdapter event) {
this.event = event;
}
Add setOnClickListener in onBindViewHolder
public void onBindViewHolder(final CatalogsViewHolder holder, final int position){
holder.imageCatalog.setOnClickListener(holder);
}
In you RecyclerView.ViewHolder implements onClickListener event.
class CatalogsViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener{
private ImageView imageCatalog;
private TextView tvCatalogName;
private View vLegendCatalog;
public CatalogsViewHolder(View itemView) {
super(itemView);
imageCatalog = (ImageView) itemView.findViewById(R.id.i =vCatalogItem);
tvCatalogName = (TextView)itemView.findViewById(R.id.tvCatalogName);
vLegendCatalog = itemView.findViewById(R.id.vLegendCatalog);
}
#Override
public void onClick(View v) {
event.onClickImageCategory(catalogsList.get(getAdapterPosition()));
}
}

Post Message On Facebook wall without showing Login page again

I am developing an application in Android to post a message in users Facebook wall.Lots of examples and Links are available but the problem is that.
In My application the user will Login to his/her's Facebook accounts at the time of installation only.Then whenever he/she presses the a particular button customized Message have to be posted in Facebook wall without asking to login again.
In the available examples the login page will appear and user has to login again. help...
EDIT: i am again Clarifying My idea.My application is to post the users location into Facebook wall to get help when the user presses the Button.This is used as security application.So its not fair to login to facebook to post the message at the Time of Usage.
How to do this Please Help..
Thanks.

You should save login and password in SharedPreferences.
SharedPreferences.Editor editor = mSharedPreferences.edit();
editor.putString("access_token",facebook.getAccessToken());
editor.putLong("access_expires",facebook.getAccessExpires());
editor.commit();
See this for SharedPreferences

I am posting the following code, which perform login to facebook,post to facebook wall, showing profile image, showing friends list and logout.... hope you will enjoy :)

Android Facebook integration does not log out

I am developing a Facebook Android integration using the below code, but once I log-in through this app then it does not logout from facebook even if I logout from Facebook app or browser both from my device. So this android app can still post on my Facebook wall. How do I logout from this app if I logout from my facebook app or facebook on browser.

You can't force a logout from your app if you logout of the Facebook app, at least no API that we support with our SDK.
In theory, you could find a way to attach some sort of uninstall intent or to parse logs for any messages regarding facebook logout, but it generally is not recommended as best practice to force a logout of another app when another app logs out (its not intuitive to the user that this is going to happen).

try remove this code
if (access_token != null) {
facebook.setAccessToken(access_token);
Log.d("FB Sessions", "" + facebook.isSessionValid());
}

ListView loads with no data-Android - android

As I see you are extending ListActivity. So below code must throw a NPE. lv = (ListView)findViewById(R.id.list); lv.setAdapter(adapter); You should use below code at onComplete method instead; setListAdapter(adapter); or getListView().setAdapter(adapter);
