Hi Jaehong, I've seen your patch this morning, but I still found some memory leak issues that cause application crashed after few minutes due to JNI local reference table overflow. (My client just keeps polling to server every 5 seconds) I think I've found where the memory leak occurs although I'm not sure why they're not handled by JVM. Based on your patch, I add few lines in EDR implementation to prevent memory leak and now it has been tested to run for thirty minutes without crash. Once I confirm the patch does fix the issue, I can try to submit it. Thank you!

Recently we found an issue in CA with BT transport where InputStream is created for each BT read. So I had fixed that problem and submitted patch @ https://gerrit.iotivity.org/gerrit/#/c/2017/ With above fix, we are able to transmit the data between devices using CA sample as BT support is not yet integrated with RI and samples. Please check the latest version. If you have the same problem, log a jira ticket with debug log. (Scons build using option RELEASE = 0) @ http://jira.iotivity.org Regards, Jaehong. ------- Original Message ------- Sender : Hung Yu-Hsin<hungys at hotmail.com> Date : 2015-07-30 18:29 (GMT+09:00) Title : [dev] [Android] JNI local reference table overflow (CA) Hi All, Recently I found that the multi transport restriction of Android in CA's scons script is removed, so I tried to build a new aar to support IP/EDR/LE simultaneously. My application runs well before I added reference to the new aar, although it only support IP adapter due to IoTivity limitation. After integrate with the new aar, the Android sample app: simpleclient and simpleserver, work great with Bluetooth EDR connection, but often crashed on my application. Basically my client will do polling to server periodically (assume 5s), and the app always crashed after about one minute. The log says there is an error: "JNI ERROR (app bug): local reference table overflow (max=512)", so I guess there are some issues in the CA implementation. Also, if I set the period more frequently, almost no operation will succeed (findResource, get...), I suspect the implementation of EDR is not thread-safe, so the data operation on the Bluetooth interface will lead to unexpected behavior? Here are some logs of my application for this issue: http://pastie.org/10319711 Thanks!
