Stream app stopped working about facebook-android-sdk

[soneff]

Can you provide a stack trace or some more detailed debugging information to reproduce the issue? Is it an "Application Not Responding" error?

I am attaching the stack trace. I get 'Force-Close' error.

Interesting, it looks like the cached stream data is corrupted or incomplete. The easiest way to fix it might be to simply uninstall the app and reload it on the device / emulator, this will clear the cached data.

However, before you do that, to find the root cause of the problem, could you do the following to help debug: add "Log.d("Cached Data", cached);" on line 56 of StreamHandler.java (immediately after "String cached = FileIO.read(getActivity(), CACHE_FILE);" ... then email me the cached data that it prints to the log? (ssoneff at facebook)

Thanks for pointing this out.

I emailed you the .apk.

I have the same issue.

hi soneff ,
I have this issue even when i has remove this application , install , run the application and login again.

But when I add the following code, I found the problem seems to be fixed.

StreamRenderer.renderComment(StreamRenderer.java 488)

if(from != null){
String authorId = from.optString("id");
String authorName = from.optString("name");
String message = comment.optString("message");
append("<div class="comment">");
renderAuthor(authorId, authorName);
String[] chunks = {
" ",
message,
""
};
append(chunks);
}

I had the same issue and daen's fix worked for the stream app for me as well!

[soneff]

Ya, adding a null check will fix it, but it's not really a general solution (the data shouldn't have null values in the first place). If you could apply the logging trick I mentioned above (Log.d("Cached Data", cached); ... on line 56 of StreamHandler.java, right after reading the cached data) when you reproduce the issue, and can send the log to me, it would be helpful to fix this on the server and prevent the error.

[soneff]

I was able to reproduce this and it is a server-side problem: I'll look into a quick fix or will patch the SDK with the null check. Thanks for your feedback.

[soneff]

This should be fixed now.
