Question

I want to show details of an exception that occurred in my application, like the line number of the exception. Is this possible?

Yes. There are lots of information about your exception in stackTraceElement in the following example.

customize this method:

private static String getExceptionDetails(Activity act, Exception e) {
    StackTraceElement[] stackTraceElement = e.getStackTrace();

    String fileName = "";
    String methodName = "";
    int lineNumber = 0;

    try {
        String packageName = act.getApplicationInfo().packageName;
        for (int i = 0; i < stackTraceElement.length; i++) {
            if (stackTraceElement[i].getClassName().startsWith(packageName))
            {
                fileName = stackTraceElement[i].getFileName();
                methodName = stackTraceElement[i].getMethodName();
                lineNumber = stackTraceElement[i].getLineNumber();
                break;
            }
        }
    } catch (Exception e2) {
    }

    return fileName + ":" + methodName + "():line "
            + String.valueOf(lineNumber);
}
