That would be a question for the people who wrote HttpClient.

Re: [android-developers] Re: App Crash during HTTP Post
Post the full logcat trace. Make sure you're not doing any network operations in the UI thread. Google 'java multi-part upload' for tips on how to chunk the upload.

[android-developers] Re: App Crash during HTTP Post
Hi Murphy, I checked the logcat, it is showing: ERROR/AndroidRuntime(10335): FATAL EXCEPTION: main ERROR/AndroidRuntime(10335): java.lang.NullPointerException But the issue is, this crash is only occurring when I do HTTP Post of a large file (10 MB). Is it a Android limitation? Anyone encountered this before?

Is there any way to solve this issue? How do I handle for such errors? Use adb logcat, DDMS, or the DDMS perspective in Eclipse to examine LogCat and look at the stack trace associated with your crash. -- Mark Murphy (a Commons Guy)http://commonsware.com|http://github.com/commonsguyhttp://commonsware.com/blog|http://twitter.com/commonsguy _The Busy Coder's Guide to *Advanced* Android Development_ Version 2.0 Available! -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: App Crash during HTTP Post
Hi Murphy, I am using File Entity to get the file and subsequently do HTTP Post as shown in the code snippet below. HttpClient client = new DefaultHttpClient(); HttpPost post = new HttpPost(postURL); FileEntity bin = new FileEntity(file, postURL); post.setEntity(bin); HttpResponse response = client.execute(post); Not sure whether this way of doing the HTTP Post is causing a crash when the file size is too big.
