Hi all, I'm in the middle of developing my first android application and have finally hit a significant roadblock that I can't seem to figure a way around.
The application involves HTTPS posting from an activity within the app to my test server. While I've worked around accepting the self-signed certificate, the behavior of the post and response has been problematic and non-standard and so I'm wondering if this issue is android related and what some possible solutions might be. Essentially this transaction is completed on a click. On the click I create and connect a HttpsURLConnection to the server, setting DoOutput and DoInput to true. I get the connection output stream and wrap it in a BufferedOutputStream. I write the transaction to the BuffStream, flush and close it. Then I handle the response. If the response is HTTP_OK, I get and wrap the connection input stream in a BufferedInputStream. I then take the input and put it into a byte array to be handled by the app and close the input stream. Now this all seems straight forward but when tested doesn't work properly. From the activity, the process is always successful on the first try, but then from the same activity if I wait a few seconds then click again, the same process will fail claiming a java.io.IOException(stream is closed), and then if I wait a few more seconds and try again it will work and this pattern continues on. To make things even more confusing, if I execute all of the clicks in rapid succession they will all work. It only complains if I wait in between transactions. I've come to think that the problem has something to do with Android HTTPS as when I try just a simple HTTP post, everything works fine. I also don't think it has anything to do with my custom certificate accepting as when I removed that and tried HTTPS posting to a trusted well known certificate, the problem still occurred. I'm leaning towards the thought that this has something to do with setting up and tearing down HTTPS connections in android, but as I do this all in an onClick event I'm not sure why I'm experiencing problems half the time. I'm also inclined to think its the inputStream that is having issues as the server seems to recieve the transactions. Anyone with any ideas as to what could be going wrong, or anyone who can outline how they went about setting up an HTTPS post on click would be greatly appreciated! Thanks so much for your time and consideration. -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
