I've already searched google and stackoverflow but I can't find a solution. I'm trying to integrate facebook into my App so users can suggest new Beer Brands directly to my facebook fanpage thorugh my app. Because right now I'm getting like 3 e-mails a day where users suggest new beer brands.
What I did: - Created a facebook developer account, enabled Native Android app and inserted the Key-Hash etc. - downloaded and integrated the facebook sdk. - addet internet permission - integrated the following facebook helper class:
package com.celticwolf.nsod; //changed
import com.facebook.android.*;
import com.facebook.android.Facebook.DialogListener;
import android.app.Activity;
import android.content.Context;
import android.content.SharedPreferences;
import android.content.SharedPreferences.Editor;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.view.Window;
import android.widget.Toast;
public class ShareOnFacebook extends Activity{
private static final String APP_ID = "35253892647899"; // changed
private static final String[] PERMISSIONS = new String[] {"publish_stream"};
private static final String TOKEN = "access_token";
private static final String EXPIRES = "expires_in";
private static final String KEY = "facebook-credentials";
private Facebook facebook;
private String messageToPost;
public boolean saveCredentials(Facebook facebook) {
Editor editor = getApplicationContext().getSharedPreferences(KEY, Context.MODE_PRIVATE).edit();
editor.putString(TOKEN, facebook.getAccessToken());
editor.putLong(EXPIRES, facebook.getAccessExpires());
return editor.commit();
}
public boolean restoreCredentials(Facebook facebook) {
SharedPreferences sharedPreferences = getApplicationContext().getSharedPreferences(KEY, Context.MODE_PRIVATE);
facebook.setAccessToken(sharedPreferences.getString(TOKEN, null));
facebook.setAccessExpires(sharedPreferences.getLong(EXPIRES, 0));
return facebook.isSessionValid();
}
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
facebook = new Facebook(APP_ID);
restoreCredentials(facebook);
requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.facebook_dialog);
String facebookMessage = getIntent().getStringExtra("facebookMessage");
if (facebookMessage == null){
facebookMessage = "Test wall post";
}
messageToPost = facebookMessage;
}
public void doNotShare(View button){
finish();
}
public void share(View button){
if (! facebook.isSessionValid()) {
loginAndPostToWall();
}
else {
postToWall(messageToPost);
}
}
public void loginAndPostToWall(){
facebook.authorize(this, PERMISSIONS, Facebook.FORCE_DIALOG_AUTH, new LoginDialogListener());
}
public void postToWall(String message){
Bundle parameters = new Bundle();
parameters.putString("message", message);
parameters.putString("description", "topic share");
try {
facebook.request("me"); // <------ here it fails
String response = facebook.request("me/feed", parameters, "POST");
Log.d("Tests", "got response: " + response);
if (response == null || response.equals("") ||
response.equals("false")) {
showToast("Blank response.");
}
else {
showToast("Message posted to your facebook wall!");
}
finish();
} catch (Exception e) {
showToast("Failed to post to wall!");
e.printStackTrace();
finish();
}
}
class LoginDialogListener implements DialogListener {
public void onComplete(Bundle values) {
saveCredentials(facebook);
if (messageToPost != null){
postToWall(messageToPost);
}
}
public void onFacebookError(FacebookError error) {
showToast("Authentication with Facebook failed!");
finish();
}
public void onError(DialogError error) {
showToast("Authentication with Facebook failed!");
finish();
}
public void onCancel() {
showToast("Authentication with Facebook cancelled!");
finish();
}
}
private void showToast(String message){
Toast.makeText(getApplicationContext(), message, Toast.LENGTH_SHORT).show();
}
}
and I've addet the following Code to access the helper class:
private void shareonfb(){
Intent postOnFacebookWallIntent = new Intent(this, ShareOnFacebook.class);
postOnFacebookWallIntent.putExtra("facebookMessage", "Teeeeeeeeeeeest");
startActivity(postOnFacebookWallIntent);
}
Where it fails: - I'm able to log into facebook but when it asks if I want to share it fails at the following codeblock:
public void postToWall(String message){
Bundle parameters = new Bundle();
parameters.putString("message", message);
parameters.putString("description", "topic share");
try {
facebook.request("me"); // <------------- here it fails and jups to catch
String response = facebook.request("me/feed", parameters, "POST");
Log.d("Tests", "got response: " + response);
if (response == null || response.equals("") ||
response.equals("false")) {
showToast("Blank response.");
}
else {
showToast("Message posted to your facebook wall!");
}
finish();
} catch (Exception e) {
showToast("Failed to post to wall!");
e.printStackTrace();
finish();
}
}
here is the log: (i've marked the part where it fails)
