java - Android: time intervals with deep sleep (System.nanoTime(), System.currentTimeMillis(), SystemClock.elapsedRealtimeNanos()) -

-

I am implementing an application in which the minimum API level is 14 (this is important) and it is used to measure frequent interval the wanted. There is no need for MS precision, it should always calculate the time (spent seconds).

So far, for the treatment of time intervals, I knew these solutions:

  1. System.nanoTime () - If Android is running It works so well, but closes on deep sleep (it is bad).
  2. System.currentTimeMillis () - Good, but not fair because it's by user or code by SetCurrentTimeMillis (long) .
  3. SystemClock.elapsedReautimeNanos () - Time has passed on deep sleep, but API level 17 is required.

    is there any other way of measuring an appropriate second precision interval to measure on API 14?
    I used to think about using System.currentTimeMillis () to listen to the broadcast clock or not that the system clock has changed. Although this does not seem to be the best solution.

    Have you tried?

php - How can I cram 6+31 numeric characters into 22 alphanumeric characters? -

-
I have a 6 digit number and a 31-digit number (such as "234536" and "201103231043330478311223582826") that I The API needs to be crawled in the same 22-character alphanumeric field that uses PHP. I tried to convert each one to 32 (using custom code could not handle the base_convert () large number) and to connect with a single-character delimiter, but It only gives me 26 characters This is a restore API, so the letters should be URI-protected. I would like to do a database table cross with two references without reference to another reference value, if possible, any suggestions? Instead use a radix of 62. This will give you 22 characters for the top, 3.35 for the pre and 17.3 for the next. & gt; & Gt; & Gt; Math.log (10 ** 6) /math.log (62) 3.3474826039165504 & gt; & Gt; & Gt; Math.log (10 ** 31) /math.log (62) 17.295326786902177

logging - How can I log both the Request.InputStream and Response.OutputStream traffic in my ASP.NET MVC3 Application for specific Actions? -

-
For a specific set of tasks, I need to log in to the incoming request inputstream as well as outgoing response. is. I am using an ActionFilterAttribute for this and overriding the OnActionExecuted and OnResultExecuted methods. So I'm starting with this idea ... Public category ActionLoggerAttribute: ActionFilterArrbit {Public Override Zero On-Offed Execution (ActionActioned Contact Filter Filter) {base.OnActionAxecuted (FilterContext); HttpRequestBase request = filterContext.HttpContext.Request; // TODO: Log the request. InputStream} Public Override Zero OnResultExecuted (ResultExecutedContext FilterContext) {base.OnResultExecuted (filterContext); HTTPRPSPointBase Response = FilterContacts Hpptex response; // TODO: Log on Response.OutputStream}} Ideally I'll hook it up with enterprise library logging because I'm already using it for error logging. Am I reaching the input and output stream at the right time? Can I easily use the Enterprise Library to log i...
