Sharing to Facebook shows error "We are Sorry, this post is no longer available. It may have been removed"

I'm trying to implement Facebook sharing in my game using Unity 3D + Facebook Unity SDK. But when I tried testing to post to my wall, this error shows up: "We are Sorry, this post is no longer available. It may have been removed." Can anybody help me? Thanks in advance.
BTW, here's my code:
using UnityEngine;
using System.Collections;
public class FacebookController : MonoBehaviour {
public bool isUsingFacebook = true; //Are we using Facebook SDK? This variable is only
//Feed parameters.
private string link = "market://details?id=com.LaserCookie.Queue"; //The link that will show the user the game's google play store address
private string linkName = "Queue"; //The link name
private string linkCaption = "Wow this game is great! 10/10 must play!"; // The caption of the link
private string linkDescription = "I achieved the score of " + PlayerController.instance.score.ToString() + "! Try to beat me if you can!"; //The description of the link
private string picture = "http://www.drycreekequestriancenter.com/testImage.jpeg"; //This is the image / game icon for the link. For now, it's shamelessly got from a random source. Thank you, random citizen...
void Awake()
{
}
// Use this for initialization
void Start () {
}
// Update is called once per frame
void Update () {
}
//Init FB
private void Init()
{
if (!FB.IsInitialized)
{
FB.Init(OnInitComplete, OnHideUnity);
}
}
//Callback that will be called when the initialization is completed
private void OnInitComplete()
{
Debug.Log("FB.Init completed: Is user logged in? " + FB.IsLoggedIn);
//Check if we are logged in.
//If not, we will log in.
//If we are, post status.
if (!FB.IsLoggedIn)
{
LoginWithPublish();
}
else
{
PostImpl();
}
}
//Callback that will be called when the game is shown / not
private void OnHideUnity(bool isGameShown)
{
Debug.Log("Is game showing? " + isGameShown);
}
//Post to Facebook. This is the only exposed method because we only use this to post to Facebook.
//The initialization and login will be called when needed.
//It will first detect whether or not we have been initialized. And will init if we haven't.
//Then it will check whether or not we have been logged in with publish. And will log in if not.
public void PostToFacebook()
{
//Are we using facebook SDK?
if (isUsingFacebook)
{
if (!FB.IsInitialized) //Check for initialization
{
Init();
}
else if (!FB.IsLoggedIn) //Check for login
{
LoginWithPublish();
}
else //Post if we are already initia;ized and logged in
{
PostImpl();
}
}
}
//The true implementation of the posting
private void PostImpl()
{
FB.Feed("",link, linkName,linkCaption,linkDescription,picture);
}
//Login to Facebook with publish
private void LoginWithPublish()
{
// It is generally good behavior to split asking for read and publish
// permissions rather than ask for them all at once.
//
// In your own game, consider postponing this call until the moment
// you actually need it.
FB.Login("publish_actions", LoginCallback);
}
//Login callback
void LoginCallback(FBResult result)
{
if (result.Error != null)
{
Debug.Log( "Error Response:\n" + result.Error );
//TODO: Retry login if we have error? Or do we display a pop up?
}
else if (!FB.IsLoggedIn)
{
Debug.Log( "Login cancelled by Player" );
//TODO: Do we display a pop up?
}
else
{
Debug.Log( "Login was successful!" );
PostImpl();
}
}
}

You need to add Key Hash for FB application.
Go to My Apps, select you application, open Setting tab, add platform for android, and add you key hash.
check this link out
Setting a Release Key Hash

I've fixed the issue. It turns out it's because I used my still in development google store address as the link. I thought it would be automatically recognized regardless of my app is live or not. Thank you anyway. :)

How to get Wechat authorization token?

Target: get token which I need to send to the app server
Problem: registered returns true, requests done returns true, but onReq and onRespdid not get called. Here is the code:
public class WeChatActivity extends Activity implements IWXAPIEventHandler {
private static final String APP_ID = ;
private IWXAPI api;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_signin);
api = WXAPIFactory.createWXAPI(this, APP_ID, true);
api.handleIntent(getIntent(), this);
regToWx();
getAuthToken();
}
private void regToWx() {
api.handleIntent(getIntent(), this);
boolean registered = api.registerApp(APP_ID);
L.e(this, "registered: " + registered);
}
#Override
protected void onNewIntent(Intent intent) {
super.onNewIntent(intent);
setIntent(intent);
api.handleIntent(intent, this);
}
public void getAuthToken() {
SendAuth.Req req = new SendAuth.Req();
req.scope = "post_timeline";
req.state = "none";
boolean requestDone = api.sendReq(req);
L.e(this, "request done: " + requestDone);
SendAuth.Resp resp = new SendAuth.Resp();
requestDone = api.sendResp(resp);
L.e(this, "request done: " + requestDone);
}
#Override
public void onReq(BaseReq baseReq) {
L.e(this, "scope: " + ((SendAuth.Req) baseReq).scope);
}
#Override
public void onResp(BaseResp baseResp) {
L.e(this, "token: " + ((SendAuth.Resp) baseResp).token);
}
}
Log cat output:

I've face the same problem and solved with two steps.
First check if you've successfully jumped to the wechat app and authorized.
If not, check if you're using the same signing key that you signed to wechat.
(ex. if you signed with the release key and compile with debug key, then wechat app won't open)
Second, by wechat document, the class name should be WXEntryActivity and should be put under a package named wxapi under the package with the name you registered at wechat.
Example in the document: If you register with "net.sourceforge.simcpux", the project structure should look like this
Also, add api.HandleIntent(getIntent(), this) after sendReq and sendResp
Not sure if the classname is neccessary, but I'm sure you can call sendReq in other class and process response with WXEntryActivity
Hope this is helpful.

had the same issue! Edwards answer helped a lot.
WxEntryActivity needs to be in the package with the name you registered at wechat!
Especially when you have multiple build variants (debug, release):
Wechat login - do not receive token

onReq and onResp will be called in WXEntryActivity.java within JAVA reflection
Suppose package name io.github.you
You should create a directory named wxapi,then create a WXEntryActivity.java
You get io.github.you.wxapi.WXEntryActivity.java
In AndroidManifest.xml
<activity
android:name=".wxapi.WXEntryActivity"
android:exported="true"
android:label="#string/title_activity_wxentry"
android:screenOrientation="portrait"
android:theme="#android:style/Theme.NoDisplay" >
In WXEntryActivity.java
public class WXEntryActivity implements IWXAPIEventHandler{
#Override
public void onReq(BaseReq arg0) {
SendAuth.Resp r = (SendAuth.Resp)resp;
String code = r.code;
}
#Override
public void onResp(BaseResp arg0) {
// TODO Auto-generated method stub
}
}
Good Luck

Codenameone when I read the qrCode uzing Zxing on Android the application goes back to 'init' and 'start'

I am using Codenameone and ZXing to read a QRCode. When I call the Scanner, my mobile opens the QRCode reader application and I get to read the QRCode except that when android takes me back to my app it goes through init then start statuses. Which moves me back to the login form of my application instead of continuing filling the form that I was in.
Any help on what to do to stay in the same form? Is there something I'm doing wrong? Thanks in advance.
EverproX.addMessage("Before Scan\n");
CodeScanner.getInstance().scanQRCode(new ScanResult() {
public void scanCompleted(String contents, String formatName, byte[] rawBytes) {
EverproX.addMessage("Scan Completed "+contents);
}
public void scanCanceled() {
EverproX.addMessage("Scan Cancelled");
}
public void scanError(int errorCode, String message) {
EverproX.addMessage("Scan Error "+errorCode+" "+message);
}
});
EverproX can be seen as a log class.
By analyzing our log we can say that as soon as we call the CodeScanner.getInstance().scanQRCode() the application is called for 'Destroy'. Then after the scanning is done it goes again through the init and start. It never goes into the scanComplete scanCanceled or scanError Callbacks.
Is it normal that the App is destroyed upon call of CodeScanner? Many thanks.

Inside your codenameone project, you should find a class named (for example MyApp.java) based on your app's name, modify the code to read something like similar to this:
public class MyApp {
private Form current;
public void init(Object context) {
// Pro users - uncomment this code to get crash reports sent to you automatically
Display.getInstance().addEdtErrorHandler(new ActionListener() {
public void actionPerformed(ActionEvent evt) {
evt.consume();
Log.p("Exception in AppName version " + Display.getInstance().getProperty("AppVersion", "Unknown"));
Log.p("OS " + Display.getInstance().getPlatformName());
Log.p("Error " + evt.getSource());
Log.p("Current Form " + Display.getInstance().getCurrent().getName());
Log.e((Throwable) evt.getSource());
Log.sendLog();
}
});
}
public void start() {
if (current != null) {
current.show();
return;
}
new StateMachine("/theme");
}
public void stop() {
current = Display.getInstance().getCurrent();
}
public void destroy() {
current = null;
}
}

OnMessageReceived not called in WearableListenerService

I am working on android wear app using Eclipse IDE.I am using same package names for wear app and mobile app and i am packing wearable app manually according to google documentation.Everything is working fine.it is installed on Android wear emulator using usb debugging with phone.
My problem is when i am sending a message to wearable using following code
List<Node> nodeList=getNodes();
for(Node node : nodeList) {
Log.v(" ", "telling " + node.getId() );
PendingResult<MessageApi.SendMessageResult> result = Wearable.MessageApi.sendMessage(
mGoogleApiClient,
node.getId(),
START_ACTIVITY_PATH,
null
);
result.setResultCallback(new ResultCallback<MessageApi.SendMessageResult>() {
#Override
public void onResult(MessageApi.SendMessageResult sendMessageResult) {
Log.v(" ", "Phone: " + sendMessageResult.getStatus().getStatusMessage());
}
});
}
the OnPeerConnected method is running when devices are peered but OnMessageReceived never called in WearableListenerService.This is my WearableListenerService code:
public class DataLayerListenerService extends WearableListenerService {
private static final String TAG = "DataLayerSample";
private static final String START_ACTIVITY_PATH = "/start/MainActivity";
private static final String DATA_ITEM_RECEIVED_PATH = "/data-item-received";
private static final String LOG_TAG = "log";
#Override
public void onPeerConnected(Node peer) {
super.onPeerConnected(peer);
String id = peer.getId();
String name = peer.getDisplayName();
Log.d(LOG_TAG, "Connected peer name & ID: " + name + "|" + id);
}
#Override
public void onDataChanged(DataEventBuffer dataEvents) {
System.out.println("Recevive message3");
}
#Override
public void onMessageReceived(MessageEvent messageEvent) {
System.out.println("service watch message1");
if (messageEvent.getPath().equals(START_ACTIVITY_PATH)) {
System.out.println("service watch message2");
Intent startIntent = new Intent(this, MainActivity.class);
startIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(startIntent);
}
}
}
Also a warning message in Logcat always appears :
app does not match record's app key: AppKey[com.myapp,c3f31717fa35401056c20a2798907f1232efa75e] != AppKey[com.myapp,f36e726eefc7e528db26a1c25f6fbf2f93dacd70]
If app key for both apps should be same then how can i create same app key for both the apps.
Any help is highly appreciated,
Thanks.

The error message you have:
app does not match record's app key:
AppKey[com.myapp,c3f31717fa35401056c20a2798907f1232efa75e] !=
AppKey[com.myapp,f36e726eefc7e528db26a1c25f6fbf2f93dacd70]
Indicated that your apps are signed with the different keys.
Package names of phone and wearable apps are the same - that is good, but they also need to share the same signature. This is the reason why messages cannot be delivered - wearable apps are recognized as "part of the same app" based on the package name and signature.
Please make sure that you have both apps signed with the same key. If you are testing the autoinstallation feature please make sure to uninstall the debug version of wearable app from watch emulator.

I had the same error, my fault was that the "wear" module's package name was not the same as the app's.
BAD:
[module: app] es.voghdev.myapp
[module: wear] es.voghdev.myapp.wear
GOOD:
[module: app] es.voghdev.myapp
[module: wear] es.voghdev.myapp
Made me waste so much time!! >:-(

Use an asyntask to send messages as they will block the ui thread. Also you need to call the await method. To get the apps to have the same key, you need to use build variants with gradle.
public class SendMessageTask extends AsyncTask<Void, Void, Void> {
#Override
protected Void doInBackground(Void... voids) {
NodeApi.GetConnectedNodesResult nodes =
Wearable.NodeApi.getConnectedNodes(apiClient).await();
for (Node node : nodes.getNodes()) {
Wearable.MessageApi
.sendMessage(apiClient, node.getId(), "/start/MainActivity", null)
.await();
}
return null;
}
#Override
protected void onPostExecute(Void aVoid) {
super.onPostExecute(aVoid);
Toast.makeText(MainActivity.this, "Message Sent", Toast.LENGTH_SHORT).show();
}
}

PlayHaven Android integration

I'm trying to implement PlayHaven's SDK in my Android application and while I do get Interstital ads, I cannot seem to capture the event of content dismissed.
I do get a log when the content is loaded.
This is what I've tried:
PlayHaven.configure(this, R.string.token, R.string.secret);
OpenRequest open = new OpenRequest();
open.send(this);
placement = new Placement("some_placement");
placement.setListener(pl); //PlacementListener
placement.preload(this);
The PlacementListener(pl) implementation:
private PlacementListener pl = new PlacementListener() {
#Override
public void contentLoaded(Placement placement) {
Log.i(TAG_PH, "PlayHaven contentLoaded");//this log is displayed
startActivity(FullScreen.createIntent(Splash.this,placement));
}
#Override
public void contentFailed(Placement placement, PlayHavenException e) {
Log.i(TAG_PH, "PlayHaven contentFailed");
}
#Override
public void contentDismissed(Placement placement, DismissType dismissType,
Bundle data) {
Log.i(TAG_PH, "PlayHaven content Dismissed");//this log is **NOT** displayed
}
};

In your onActivityResult method, you can use the following code:
String placementTag = data.getStringExtra(PlayHavenView.BUNDLE_PLACEMENT_TAG);
PlayHavenView.DismissType dismissType = (PlayHavenView.DismissType) data.getSerializableExtra(PlayHavenView.BUNDLE_DISMISS_TYPE);
You will get back dismissType. The values you are looking for are EmergencyClose (triggered when a user clicks on the X button to close a content unit), NoThanks (user declines the content unit offer), SelfClose (the Content Unit dismisses itself which happens when the SDK has to intelligently close a content unit), and BackButton (when the user presses back).
