Android: facebook post programmatically with FB SDK 4.x

Question

I want to post to facebook without dialogue, just programmatically, I'm trying with

public void login(CallbackManager callbackManager) { LoginManager.getInstance().registerCallback(callbackManager, new FacebookCallback<LoginResult>() { @Override public void onSuccess(LoginResult loginResult) { Log.d(LOGTAG, "facebook login success"); share("kk"); } @Override public void onCancel() { Log.w(LOGTAG, "facebook login canceled"); share("kk"); } @Override public void onError(FacebookException exception) { Log.e(LOGTAG, "facebook login error"); exception.printStackTrace(); } }); LoginManager.getInstance().logInWithPublishPermissions((Activity) context, Arrays.asList("publish_actions")); } public void share(final String msg) { Log.d(LOGTAG, "facebook sharing new message"); Set<String> permissions = AccessToken.getCurrentAccessToken().getPermissions(); AccessToken accessToken = AccessToken.getCurrentAccessToken(); Bundle postParams = new Bundle(); postParams.putString("name", "yourTitle"); postParams.putString("caption", "yourCaption"); postParams.putString("description", "yourDesc"); postParams.putString("message", "yourMessage"); GraphRequest request = new GraphRequest(accessToken, "me/feed", postParams, HttpMethod.POST, null); AsynTaskGraphRequest asynTaskGraphRequest = new AsynTaskGraphRequest(request); asynTaskGraphRequest.execute(); } 

the problem is that when the application is registered on facebook, it shows the message "This does not allow the application to post to facebook", although I use

 LoginManager.getInstance().logInWithPublishPermissions((Activity) context, Arrays.asList("publish_actions")); 

On the other hand, how can I check if the user was still registered in fb to call logInWithPublishPermissions only once?

Thanks!

As @Ankush said, you need to register as an authorized developer in the application settings on the facebook developer website.

My last code (works fine now):

 public class FbManager { private Context context; private static final String LOGTAG = "FbManager"; private CallbackManager callbackManager; public FbManager(Context context, CallbackManager callbackManager){ this.context = context; this.callbackManager = callbackManager; } public static void traceKeyHash(Activity activity){ try { PackageInfo info = activity.getPackageManager().getPackageInfo("com.muv.android", PackageManager.GET_SIGNATURES); for (Signature signature : info.signatures) { MessageDigest md = MessageDigest.getInstance("SHA"); md.update(signature.toByteArray()); Log.i(LOGTAG, "Share - KeyHash: " + Base64.encodeToString(md.digest(), Base64.DEFAULT)); } } catch (Exception e) { e.printStackTrace(); } } public void share(final String msg) { if (isLoggedIn()) { post(msg); } else{ LoginManager.getInstance().registerCallback(callbackManager, new FacebookCallback<LoginResult>() { @Override public void onSuccess(LoginResult loginResult) { Log.d(LOGTAG, "facebook login success"); post(msg); } @Override public void onCancel() { Log.w(LOGTAG, "facebook login canceled"); } @Override public void onError(FacebookException exception) { Log.e(LOGTAG, "facebook login error"); exception.printStackTrace(); } }); LoginManager.getInstance().logInWithPublishPermissions((Activity) context, Arrays.asList("publish_actions")); } } public boolean isLoggedIn() { AccessToken accessToken = AccessToken.getCurrentAccessToken(); return accessToken != null; } private void post(final String msg){ Log.d(LOGTAG, "facebook posting new message"); Set<String> permissions = AccessToken.getCurrentAccessToken().getPermissions(); AccessToken accessToken = AccessToken.getCurrentAccessToken(); Bundle postParams = new Bundle(); postParams.putString("message", msg); GraphRequest request = new GraphRequest(accessToken, "me/feed", postParams, HttpMethod.POST, null); GraphRequestAsyncTask asynTaskGraphRequest = new GraphRequestAsyncTask (request); asynTaskGraphRequest.execute(); } }
