Easy Facebook Android SDK

I have been working on it this afternoon and it doesn't seem to work. So I have one question can you please give me an example with FacebookApplicationSite or if you explain what this is. I really appreciate it.

I read all of the website but I still need some clarification on the tutorial. I got 80% working I get the permission the login but when I log in I get a blank (white page) so I know that the login has been successful but what i want to achieve is posting to my wall or update my status if you can give me a clear path of how to achieve that I would really appreciate it .

I never get to enter my status and when I log in it just goes into a blank page.

ok I'm going to work on it, and on which file should insert the desired message. Again thank you for the huge help.

you used an example from our demo page or have integrated the library into your own application? Try a sample from the demo page

What permissions do you put in the array String permissions[] ?

Hi Eugenio Romano,

I was wondering what would be the problem in myStatus_1.2.2.zip.
I have the same problem as white8824.

"I just imported the myStatus and change the parameters with those of my application in fbManager. Everytime when I execute this, it has a toast "Login failed". "

How can I track the bug?

Thanks for your help.

Thanks for your advice.

Your sdk is great. I think the bug was in the Android Facebook app. (https://github.com/facebook/facebook-android-sdk/issues/191)
Anyway I wiped out all the user data and restarted the emulator and worked.

thanks. thats great to hear. could you point me in the right direction with what API call I can post comments to fan pages ? thanks a bunch.

Hi Michael do you have setted this page "http://www.hasrobotics.com/accesstokenpage/" in the Connect section of the Control Panel of your facebook apllication?

Website->Site URL

Hi Mario,

this is a truly amazing library. I really wished I understand how you get around the hash code logic. Amazing.

I am nearly there. I face one more issue. Here a code snipplet:

GraphApi graphApi= new GraphApi(facebook);

Page p = graphApi.getPage(Global.FacebookFanPage);

List<Feed> lst = new ArrayList<Feed>();

lst = graphApi.getAllPostFriends( Global.FacebookFanPage );

String ret = graphApi.postToFriend("test", Global.FacebookFanPage );


I get the fan page object. That works great.
I read the wall posts of the page. That works great as well.
I try to post to the wall. This is not working. The return "ret" is null.

I use the following permissions:

String permissions[] = { "user_relationship_details",
"user_religion_politics",
"user_work_history",
"user_relationships",
"user_interests",
"user_likes",
"user_location",
"user_hometown",
"user_education_history",
"user_activities",
"read_stream",
"publish_stream",
"manage_pages",
"offline_access"};


What goes wrong here?

Thanks so much (hopefully my last question).

Michael

P.S. Once all solved I will write an article about my experience with your SDK. People need to know....

Yes people can post comments.

The user is me and I am the admin of the page.

Also what do you require when deploying to the marketplace regarding the use of your lib?

sounds good. thank you.

BTW: the problem I had earlier if I understand right had to do with the fact that I cached the FB Login but introduced a new permission. Since It always used the cached one it never asked me if I allow this new permission. How does it store the cache for FB Single Sign On and how could we force to clear in the event we introduced a new permission in the application ? Just thinking ahead here.

Gotcha. Thank you.

Use FQL.getFriend(friend_id) this returns an object of type Friend , to get pic use Friend.getPic()

Download 1.3 verison

public void onLoginSuccess(Facebook facebook) {
try{
GraphApi graphApi= new GraphApi(facebook);
List<Photo> photos = graphApi.getAllPhotosMy();
Photo photo = photos.get(0);
String pkg=getPackageName();
intentResult.putExtra(pkg+".myFoto",photo.getSource());
startActivity(intentResult);
}catch (Exception e) {
fbManager.displayToast(e.getMessage());
}
}

i got error "invalid index 0, size is 0"

sorry I am still very beginner, please give a simple example code to display current profile picture in imageview.

String permissions[] = { "user_relationship_details",
"user_religion_politics",
"user_work_history",
"user_relationships",
"user_interests",
"user_likes",
"user_location",
"user_hometown",
"user_education_history",
"user_activities",
"read_stream",
"offline_access"};

Just tested it out on my phone running on 2.2..

With regards to the facebook login page, which I think is a webview or webviewclient that you created, the normal behavior which should occur when you click on the email/password text fields is that the on-screen keyboard should pop up. However, it doesn't pop up no matter how I click on the text fields.

Can you help me out with this issue? Thanks.

Locked the keyboard in the manifest file? I don't think I did anything to the keyboard in the manifest file ..

Hmmm, good point there. It might really be something I did ..

I've another question here.

When I call fbManager.loadfacebook(int returnWindow) or fbManager.login(int returnWindow) .. I realized that you were passing in a layout resource for it to load when it was done with the webview. Is it possible for me to let it return to the previous activity view instead? e.g. A -> facebook webview -> A ..

That's because I would like it to return to the activity after it has successfully logged into facebook, and I can use the facebook graph api from that activity.

Do you have setted this page "http:// www.hasrobotics.com/ accesstokenpage/" in the Connect section of the Control Panel of your facebook apllication? "Website->Site URL"

Hi,

I've found the error I'm getting now, I'm trying to use JSONSingleObjectDecode and JSONObjectDecode but always get a JSONException thrown because the results seem to be in XML not JSON, any idea why this is happening?

Thanks,

Infinitifizz

Ah okay, it seems weird that it returns as XML rather than JSON though :S I know this isn't your fault as the URL has "format=json" on it, it's really annoying though because you have that parser in there!

Thanks for your help and keep up the great work :)

Hey Mario,

could not get the Hash generated right via the keytool. It generated one but it did not work. I am also on Win7/64bit.

I found code to actually reengineer the hash code using getPackageManager(). The hash key I got through the code worked. :-)

BTW, did you get a chance to check the issue I have reported with get Friend Posts when the limit is greater then the actual posts on the fan page ?

thanks,
Michael

Sure. Here it is:

private void getHashKey()
{
String hashKey = "";

try
{
PackageInfo info = getPackageManager().getPackageInfo("com.smartmove.android.myband.mozzak",
PackageManager.GET_SIGNATURES);
for (android.content.pm.Signature signature : info.signatures)
{
MessageDigest md = MessageDigest.getInstance("SHA");
md.update(signature.toByteArray());
hashKey = Base64.encode(md.digest());
Toast.makeText(this, hashKey, Toast.LENGTH_LONG).show();
}

}
catch (NameNotFoundException e)
{
Toast.makeText(this, e.getMessage(), Toast.LENGTH_LONG).show();
}
catch (NoSuchAlgorithmException e)
{
Toast.makeText(this, e.getMessage(), Toast.LENGTH_LONG).show();
}
}

I do have the key has set up on facebook...when I test from my Droid 2 it works fine, but when I test from a Galaxy tab I get that error.

Yes, and both devices are running Android 2.2

Aha! You found the problem!!! That's it the Galaxy Tab did not have the Facebook app installed...as soon as I installed it everything started working. Thanks!!!

Now, does this mean all users need the Facebook app installed in order to allow permissions to my app or is this specific to your API?

Thanks for all your help and for putting together this awesome API!

I guess the official facebook api was updated; I just tested it and it doesn't require the facebook app to be installed. It pops up its own browser with the facebook login or permission dialog. Would you consider implementing that functionality on your api?

and please fix the posttofriends function as well so you can post to pages that have less posts than the limit.

thanks,
Michael

Hi Mario,

sorry. my issue is with getPostFriends and not with postToFriends.

You can simply test:

- create a page
- dont post any posts or justa few
- call getPostFriends(id, limit) where the limit is greater than the posts exist on the page

Result: The call is in an endless loop.

As of right now I would need to tell my users to not use the application if the page has less than limit posts. This would not be good.

Would be great if you could check this.

Thanks,
Michael

As always, you are the MAN ! :-)

Will test it over the weekend and let you know how it goes.

Thanks again,
Michael

Allright Man.

I can only report good things. :-)

This version is working well. Awesome stuff.

Lets work on the iPhone port now. :-)

Thanks,
Michael

Try to generate Key Hash with this tool http://www.hasrobotics.com/download/keyhash.zip

I have same problem but doesnt work after key hash. I mean still not working :( same error. Strange thing is that its working on emulator, but after downloading apk on my S7 with 2.1-upgrade1 and my HTC with 2.2.1 got only FORCE CLOSE!

Yes...recheck key hash with tool in guide page of this site.

Ok.. dont get it. Everything runs fine on emulator. Everything runs fine on my tablet/phone when i directly debug/compile application from Eclipse. But when i export package and download it on device -> ERROR!

@Eugenio Romano God bless YOU my friend! It works! :D Thank you so much.

Use keystore of your apk file for android market

If you debug your app eith eclipse , try to generate Key Hash with this tool http://www.hasrobotics.com/download/keyhash.zip

If you export project as .apk file you must regenerate Key hash from new file.keyStore

You can download set status example from demo page.

There is a bug with logout method...I hope to resolve it in the next release

There is facebbok App installed on this device?

What version of Android is installed?

Do you have export this app in an .apk file or you using eclipse to run it?

You can modify code of library to force it to display a popup login.

That didnt work for me, any other suggestions? Heres the code

public void onItemClick(AdapterView<?> arg0, View arg1, int position, long arg3) {
final Dialog dialog = new Dialog(this);
dialog.setContentView(R.layout.message);
Friend f = friends.get(position);
final String id = f.id;
dialog.setTitle(id);
dialog.setCancelable(true);

final TextView text = (TextView) dialog.findViewById(R.id.message);

Button cancel = (Button) dialog.findViewById(R.id.cancel);
cancel.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
dialog.dismiss();
}
});

Button send = (Button) dialog.findViewById(R.id.send);
send.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
try {
graphApi.postToFriend(text.getText().toString(), id);
fbManager.displayToast("Posted!");
} catch (EasyFacebookError e) {
e.printStackTrace();
fbManager.displayToast("Posting failed! " + e.toString());
}
dialog.dismiss();
}
});
dialog.show();
}

Its there, just not in that segment of code. Its globally initialized.

Its not crashing or anything, it just states that Its unable to post to a users page unless they authorize the app.

thank you mario I need some help in pictures uploader and tags on pictures
I will ask you some questions about these topics
I need your email if available

thanks mario it realy help me. at least learning there is no way to connect facebook in my desire make me avoid searching how to manage that issue.

HI Mario
Thanks for your response.
can you tell me how to use access token i want to get user email and it's birthdate
Thanks,
Munish

Thanks Mario Romano

Click on download in the top of this page...

Try to use easyfacebookandroidsdk_2.2.jar

Do you have execute app in to eclipse?

If you use easyfacebookandroidsdk_2.2.jar URL not needed.
Try to do it :
1)Download an example from demo page
2)Generete Key Hash from your debug.keystore
3)Insert accessToken in your facebook application settting page.
4)Put you FacebookApplication ID in downloaded example
5)RUN IT

It's 2 different things

you not need access token with this library

Yes , but the user must first allow your application to access the her data

Not is right....

- FBLoginManager it's a manager of login/logout and session action
- FBLoginWithOutApi it's a magaer of login for the phone where facebook app not is installed

Thank you

Thanx for your reply Mario....Yeah I tried but basically where to start that I can't understand...for example, I wanna fetch feed , so how can I do that??? can u please explain me????

Turns out it was a problem with the key hash after all. I don't know why facebook made it so hard. I signed the apk, followed their instructions, even downloading OpenSSL, and it was giving me the wrong keyhash. So I downloaded the link you supplied earlier (http://www.hasrobotics.com/download/keyhash.zip) and exported and signed it using the keystore that I signed the apk file with and it gave me the correct keyhash for that keystore.

Facebook really shouldn't make it that hard...

verificate your key hash , and regenerate with tool in this page : http://www.hasrobotics.com/guide.asp

Read previous post , We have already answered this question

What do you expect after the closing of the progress bar?

no...if you want upload photo from your sdcard, you need first put him in a byte array...then change method uploadPhoto from (String , String) to (String, byte[]) and put your byte array in params.putByteArray...

Hi,

right after I posted this question I found out changing the number of requested homes fixes the problem.. it was pretty strange behavior, but apparently it's working now. Thank you for your time and this awesome sdk :)

Paul

I think your code don't work fine....However in the next release i will resolve this issue...

Read previous post , We have already answered this question

Hi Timo
