post text to facebook

post text to facebook - android

I am creating an app that take some text input from user and post it into the usr's wall
I am using following code for posting text
private void post_to_wall(String user_text) {
// TODO Auto-generated method stub
Log.d("post to wall", user_text);
try{
String response = facebook.request("me");
Bundle parameters = new Bundle();
parameters.putString("message", user_text);
parameters.putString("description", "test test test");
response = facebook.request("me/feed", parameters, "POST");
Log.d("Tests", "got response: " + response);
if (response == null || response.equals("") ||
response.equals("false")) {
Log.v("Error", "Blank response");
}
}catch(Exception e) {
e.printStackTrace();
}
}
after running this code nothing happens.No error is occuring.
Plz tell me how to check whether a user is logged in or not..Bascially what i want to do if user is logged in fb app then allow him topost text otherwise tell him to login first.
Thnx

Look at the publishStory method of sample.
https://developers.facebook.com/docs/android/publish-to-feed/
They use a HTTPPost and RequestAsyncTask. Call back which parses the response and a id is displayed as a toast to confirm success of posting
Example:
private void publishStory(String user_text) {
Session session = Session.getActiveSession();
if (session != null){
// Check for publish permissions
List<String> permissions = session.getPermissions();
if (!isSubsetOf(PERMISSIONS, permissions)) {
pendingPublishReauthorization = true;
Session.NewPermissionsRequest newPermissionsRequest = new Session
.NewPermissionsRequest(this, PERMISSIONS);
session.requestNewPublishPermissions(newPermissionsRequest);
return;
}
Bundle postParams = new Bundle();
postParams.putString("message", user_text);
postParams.parameters.putString("description", "test test test");
Request.Callback callback= new Request.Callback() {
public void onCompleted(Response response) {
JSONObject graphResponse = response
.getGraphObject()
.getInnerJSONObject();
String postId = null;
try {
postId = graphResponse.getString("id");
} catch (JSONException e) {
Log.i(TAG,
"JSON error "+ e.getMessage());
}
FacebookRequestError error = response.getError();
if (error != null) {
Toast.makeText(getActivity()
.getApplicationContext(),
error.getErrorMessage(),
Toast.LENGTH_SHORT).show();
} else {
Toast.makeText(getActivity()
.getApplicationContext(),
postId,
Toast.LENGTH_LONG).show();
}
}
};
Request request = new Request(session, "me/feed", postParams,
HttpMethod.POST, callback);
RequestAsyncTask task = new RequestAsyncTask(request);
task.execute();
}
}
Edit:
Check the facebook login sample
https://developers.facebook.com/docs/android/login-with-facebook/
The prerequisite for publish sample is to login into facebook.

Facebook login - issue after Graph request

I've been going through docs Android - Facebook login
for days still the issue that I'm facing is - just after the user logs in for first time and after the graph request and the api call,the intentToHomeScreen() method is not called. Note that this happens in rare cases. The progress bar keeps on loading.
Here's my code, sorry for posting such long post:
public class SignInActivity extends BaseActivity {
final int MY_PERMISSIONS_REQUEST_READ_CONTACTS = 1;
#BindView(R.id.sign_fb_splash_linear)

You can try with simple following code.
public class Profile_Detail extends Activity implements OnClickListener {
ImageView profile_pic;
TextView mfirstname, mlastname, mfullname, mfacebookLink, mfacebookId,
mfacebookUnm, mgender, mEmail;
private Session.StatusCallback statusCallback = new SessionStatusCallback();
#Override
protected void onCreate(Bundle savedInstanceState) {
this.requestWindowFeature(Window.FEATURE_NO_TITLE);
super.onCreate(savedInstanceState);
setContentView(R.layout.profile);
Settings.addLoggingBehavior(LoggingBehavior.INCLUDE_ACCESS_TOKENS);
Session session = Session.getActiveSession();
if (session == null) {
if (savedInstanceState != null) {
session = Session.restoreSession(this, null, statusCallback,
savedInstanceState);
}
if (session == null) {
session = new Session(this);
}
Session.setActiveSession(session);
if (session.getState().equals(SessionState.CREATED_TOKEN_LOADED)) {
session.openForRead(new Session.OpenRequest(this)
.setCallback(statusCallback));
}
}
profile_pic = (ImageView) findViewById(R.id.profile_pic);
mfirstname = (TextView) findViewById(R.id.textView1);
mlastname = (TextView) findViewById(R.id.textView2);
mfullname = (TextView) findViewById(R.id.textView3);
mfacebookLink = (TextView) findViewById(R.id.textView4);
mfacebookId = (TextView) findViewById(R.id.textView5);
mfacebookUnm = (TextView) findViewById(R.id.textView6);
mgender = (TextView) findViewById(R.id.textView7);
mEmail = (TextView) findViewById(R.id.textView8);
Session.openActiveSession(this, true, new Session.StatusCallback() {
#Override
public void call(Session session, SessionState state,
Exception exception) {
if (session.isOpened()) {
// make request to the /me API
Request.executeMeRequestAsync(session,
new Request.GraphUserCallback() {
#Override
public void onCompleted(GraphUser user,
Response response) {
if (user != null) {
mfirstname.setText(user.getFirstName());
mlastname.setText(user.getLastName());
mfullname.setText(user.getName());
mfacebookLink.setText(user.getLink());
mfacebookId.setText(user.getId());
mfacebookUnm.setText(user.getUsername()
+ " (" + user.getName() + ")");
String gender = user.asMap()
.get("gender").toString();
String email = user.asMap()
.get("email").toString();
mgender.setText(gender);
mEmail.setText(email);
StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder()
.permitAll().build();
StrictMode.setThreadPolicy(policy);
try {
URL image_value = new URL(
"http://graph.facebook.com/"
+ user.getId()
+ "/picture?type=large");
Bitmap bmp = null;
try {
bmp = BitmapFactory
.decodeStream(image_value
.openConnection()
.getInputStream());
} catch (IOException e) {
e.printStackTrace();
}
profile_pic.setImageBitmap(bmp);
} catch (MalformedURLException e) {
e.printStackTrace();
}
}
}
});
} else {
Toast.makeText(getApplicationContext(), "Error...",
Toast.LENGTH_LONG);
}
}
});
}
#Override
public void onStart() {
super.onStart();
Session.getActiveSession().addCallback(statusCallback);
}
#Override
public void onStop() {
super.onStop();
Session.getActiveSession().removeCallback(statusCallback);
}
private class SessionStatusCallback implements Session.StatusCallback {
#Override
public void call(Session session, SessionState state,
Exception exception) {
}
}
}
With this above code i am successfully able to get the detail of facebook user as well as profile picture.
