I need help!  I have an Ipad.  A pop up came on my  screen giving an htpp : ip adress and a nasty sexual message.  There is only an OK button and I cannot close it.  It seems to be have frozen my web browser .  I'm using Safari.  I read some examples on this site.  I tried to download AVAST but finally I unstalled it.  I cannot find ClamXAV.  Should I click the ok button and then close all the Windows?  Since I have no access to internet can I download G-Whizz Apps Browser?  Can I have two browsers on the same Ipad, or will I loose all my favorites and stuff from Safari?

I'm 61, not very familiar with all this computer language, but willing to learn even if I find this very difficult!  

p.s.  Now I seem unable to send this message because I need a tag.... now what is a tag.  I can see many suggestions so I will chose ipad, because this is what I have, but why I'm doing it, is a mystery???


Question: android intentService concurrency
Answer: 
  Now lets say i call this service multiple times, do the requests get queued ?


Yes, assuming that by "call this service", you mean call startService() with an Intent that resolves to this service. Quoting the documentation:


  All requests are handled on a single worker thread -- they may take as long as necessary (and will not block the application's main loop), but only one request will be processed at a time.
