---------------------------------
Summary: Upload times out and fails with 400 error sometimes -
Android
Key: CB-7901
URL: https://issues.apache.org/jira/browse/CB-7901
Project: Apache Cordova
Issue Type: Bug
Components: Plugin File Transfer
Affects Versions: 4.0.0
Environment: Android 4.4.4
Reporter: Rajat Paharia
Using:
- Cordova 4.0.0
- org.apache.cordova.file-transfer 0.4.7 "File Transfer"
- Android 4.4.4 (Moto X)
I am uploading image files from my phone to AWS S3 (via https) using the File
Transfer plugin. When using Wifi, this seems to work with no issues - I have
not been able to get it to fail. I have setup a progress callback to log to the
console and the "win" callback is called almost immediately after the last
progress event.
When using the cell network (with 1-2 out of 5 bars), on the other hand, it
fails intermittently. The progress events seem to indicate that the file is
almost done uploading, then there is a long delay, and then the fail callback
is called.
File size doesn't have any effect.
I am attaching logcats of both successes and failures. The successes show a 204
response from the AWS server shortly after the last progress event. The
failures show a long delay after the last progress event, and then a 400
response from the AWS server with the following message "Your socket connection
to the server was not read from or written to within the timeout period. Idle
connections will be closed."
Google searching on this phrase reveals that the most common cause is the
Content-Length being set to more than the number of bytes actually sent. Given
that this only happens on slower connections, I'm not sure if that's relevant
in this case.
