    Is there an error message in the logcat that shows a problem in your code?

    Copy the part of logcat that shows any problem and paste it here.
    If you don't understand my answer, don't ignore it, ask a question.

    The adb command can retrieve the logcat from a Android device attached to a PC via USB. Did you Try that.
