android - "refresh_tasks cannot be resolved or is not a field" -


I basically copy & amp; Pasted the code from the top and changed the required readings, yet I get this error I am trying to create a "refresh" item in my menu.

XML code: 

  & lt; Menu xmlns: android = "http://schemas.android .com / apk / res / android" & gt; & Lt; Item android: id = "@ + id / action_settings" Android: orderInCategory = "100" Android: showAsAction = "never" android: title = "@ string / action_settings" /> & Lt; Android Android: id = "@ + id / refresh_tasks" Android: title = "@ string / refresh" /> & Lt; / Menu & gt;   
 HomeActivity.Java Code:  
  Public Boolean Option Option (menu item) {switch (item.get ITMID)} {Case R. Id. Refresh_task: // line where I get error loading TasksFromAPI (TASKS_URL); Back true; Default: Return Super.Options item selected (item); }}   
 I searched the Internet, but I have not succeeded in fixing it. I think that something is wrong in my XML, but I do not know what it can be.   
 
 
 So, apparently my R.Java stopped updating for some reason. My code was correct, but it will not be updated to edit the AndroidManifest.xml file and then save it to RJJA to update. Before you save it, your Android Manifest.exml file is so easy to add space and then to delete the place (though, you can leave the space if you want ... this should not be the cause of any error) .

But when I comment on two {*******} (dir The loop output is obtained for the initial value of variable dir dir = -90 ), and that output is correct. The problem occurs when the loop is given. Can anyone help me in solving this problem. #include "mpi.h" int main (int argc, char * argv []) Float dir = -90; Int rank, nanoprakash; MPI_Status status; MPI_Init (& amp; argc, & argv); MPI_Comm_rank (MPI_COMM_WORLD, & amp; Rank); MPI_Comm_size (MPI_COMM_WORLD, & amp; numprocs); If (rank == 0) {/ / data to begin / / (dest = 1; dest ...

python - Apply coupon to a customer's subscription based on non-stripe related actions on the site -

I can not find anything in the source about using coupons after subscribing to a user's plan. Is it possible to use a coupon to credit a user's membership after initial subscription? If not, what is the best option? Specifically, I want to give a user 100% coupon for that month, when they take 5 [site specific actions]. This is possible, but may not be the best idea. Coupons are currently applied to the stripe, then apply again at the customer level and each client can have a single coupon. So if you are already offering discounts to the coupon, then the customer who is currently in the present will also give up. It also means that if you are using a recently-added multiple subscription capacity, then all of the user's subscription will be ready for the month. Coupons can be set to "Once", only once (as the only name) can be used by any customer, so if this credit can earn more than once, You will have to maintain a 100% discount coupon continuousl...
