    sensor closes my app!!

    I´m developing a little game and I´m using sensor api to capture accelerometer axis events. Everything works ok, but after about ten minutes playing my app closes suddenly! I did a lot of tests and finally I found that the problem is the sensor. There is a sample code called HelloSensor and after about 10 minutes it closes too!! In s60 5th emulator works ok, but it doesn´t in my 5800 with firmware version 31.0.008. Any body can help me please?

    Edit: before close I see a message saying: "memory full, applications will be closed" (translated from spanish). But with "helloSensor" (http://wiki.forum.nokia.com/index.ph...elloSensor.zip) it's the same!, it's a bug?

    thanks! I think it's a widget runtime bug. I don't know how to avoid it.

    Re: sensor closes my app!!

    It seems like a memory leak in Sensors API. I've same problem on 5800 (21.0.025): while handling sensor events, phone's free memory reduces very fast.

    Is there any way to reinitialize service object to free up some memory or to read sensor data without RegisterForNotification()?

    Question Re: sensor closes my app!!

    This thread is referenced from the phoneGap Accelerometer code with the following comment:

    // TODO: this call crashes WRT, but there is no other way to read the accel sensor
    // http://discussion.forum.nokia.com/fo...ht=memory+leak

    Any workarounds? Or other updates?

    Re: sensor closes my app!!

    Yes! With firmware version 50.0.005, Nokia 5800, has solved this issue!!

    You can test the game I'm developing using accelerometer (http://sviudes.blogspot.com/2010/04/...serpiente.html), it's an alpha version . Before this firmware version, game stops after 10 minutes playing. Installing this firmware, works ok!
