regex for a string ,\"16 questions\", -


i not in regex , spent time figure out how search below pattern:

,\"16 questions\",

this constructed .\"[0-9,]+ questions\".
think close not sure how much. can please correct it. numeric value can have comma in when number crosses 1k. e.g 2,500 questions.

,"\d{1,3}(,\d{3,3})*\squestions?",

explanation:

  • \d{1,3}= 1~3 decimal digits
  • (,\d{3,3})* = comma , 3 decimal digits, whole group repeating 0~n times
  • \s = whitespace
  • s? = letter s can missing

these 2 parts give accurate recognition of possible numbers.

▶ test , visualization.

if backslashes in text true backslashes, regex including them be

,\\"\d{1,3}(,\d{3,3})*\squestions?\\",

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m
