I got a strange crash from my Ant interfaceing app. As far as I was concerened I had finished using the app 20 minutes previously and had shutdown the api The Ant notification had was long gone. The crash was caught by Acra. Here is the stack dump.

As you can see there is nothing from my code in there. There are a few lins of interest in the logcat.

There will of been some memory presure as I was starting the OIFileManger from within IpBike it looks to me like the system decided to get rid of com.dsi.ant.service.socket which is when the error occured.

This is on an SE Active with I belive the curent version of AntRadioService, although I am not that sure how to check.

We have tracked this down to a code bug that can be triggered in the ANTLib code when the ARS is killed by the system at the same time as a call to releaseService.

There will be a release of the ANT SDK which includes this fix soon. In the meantime the problem can be fixed by removing the following redundant code from AntInterface.java (They are located in the onServiceDisconnected method of mIAntConnection):

Context oldContext mContext;
ServiceListener oldServiceListener mServiceListener;
releaseService();
initService(oldContextoldServiceListener);
