Blank Login Screen about facebook-android-sdk

[soneff]

Do you still have this issue?

Can you provide some more details? Are you trying to run one of the examples? What permissions are you requesting? What App ID are you testing with? Are you testing on a device or emulator? Does the device have network connectivity?

I am having the same problem with running the facebook-sdk example. I am using the android 2.2 api and froyo device. When I click on the Login button, it shows a loading sign and then blank screen with error title and OK button. What could be wrong?

[soneff]

Are you using a valid App ID? What App ID are you testing with?

[lakshi]

Create an account for your application using the link
http://developers.facebook.com/setup/
Then use the app_id and try again

Hi,I am also getting blank screen even after creating app_id using the above link.

[soneff]

Can you provide the App ID that you are trying to use? Does the blank dialog box have anything displayed in the title?

[corpusmobile]

Hi, I have tried running both the examples "facebookSDK-example" and "stream". They rarely display the login screen when I click the connect button, most of the times it is just a blank screen with title facebook.
my "facebookSDK-example" app name is "TestFBSDK" with app_id 115630648480232.
my "stream" app name is "CheckFBSDK" with app_id 131505246861774.

Thanks,
Bhupathi

Hi Soneff,

I do get the main screen. when i click on the Login button, i get a blank white screen (like a pop-up) with a loading window for sometime. when the loading window is done, the screen reains blank but does have 'Facebook' in the blue header.
The app ID i used is 112255338818577.

@soneff: Followup... more info on my trial..... I used ADP1 to run the facebook-sdk example in the SDK. I tried it on Android 1.6 also. I tried it via WiFi and 3G. The result was the same.

I also have a sceenshot but i cant post iages here unfortunately. Hope this can give you a better idea to help me resolve it.

I am not having this problem anymore. The problem was I had not copied the right API key in the Example.java file. Once corrected it worked like a charm.

[soneff]

@mbeelv I haven't been able to reproduce this problem with App 112255338818577 (it seems to work fine with my test account). Perhaps try the following: clear any local session state and saved cookies. This can be done by inserting the following line in Example.java:

try { mFacebook.logout(this); } catch (Exception e) { e.printStackTrace(); }

after SessionStore.restore(mFacebook, this); (Example.java: line 79)

Also check that you don't have any network connectivity issues in your test environment.

[soneff]

@corpusmobile: I haven't been able to reproduce the problem with your App IDs (they work fine with my test account). Try clearing the cookies using the technique I described above. You could also try wipe the user data on the emulator and reinstalling the app or creating a new test app.

I've asked for some server-side changes to give some debugging information rather than a blank screen, but these won't be available until the next server push early next week.

[mbeelv]

Thanks soneff, the solution worked like a charm. was able to post msgs too :)
