android - Google Play/App Store in-app purchase policies -

-

i heard on app store, sell or user buys, apple must have 30% on it. imply if open web page within app , accept donation, apple must have percentage. otherwise have redirect user make donation outside of app - instance, calling browser.

so, if it's true, wanted know if google holds same policies. couldn't find specific answer in documentation, info in-app purchase (but i'm considering scenario purchase within app, not in app (sorry if sounds confusing).

taking groupon example. if buy coupon, "in-app purchase"? don't believe google take 30% on buy there, wanted make sure according rules.

the app i'm working on have both donation , coupon purchase sponsors (walgreens, etc). ok if through webview, or have call browser?

sorry if concept of "in-app purchase" blurred.

any information on topic appreciated.

edit:

from understanding, in-app purchase (for both google , apple) api use process these payments. find confusing that, instance, in apple's in-app purchase guidelines: apple policies so, mean cannot use apple's in-app purchase sell book (but open e-commerce site in app , sell it), or cannot sell book @ inside app? know may sound dumb question, doesn't seem clear me.

the standard 30% transaction fee applies in-app transactions on google play , goes distribution partner , operating fees.

according google play developer program policies:

in-app purchases:

  • developers offering virtual goods or currencies within game downloaded google play must use google play's in-app billing service method of payment.

  • developers offering additional content, services or functionality within category of app downloaded google play must use google play's in-app billing service method of payment, except: >

    • where payment physical goods or services (e.g., buying movie tickets, or buying publication price includes hard copy subscription); or
    • where payment digital content or goods may consumed outside of app (e.g., buying songs can played on other music players).

with in-app purchase on ios , os x, can offer customers additional digital content, functionality, services , subscriptions within paid or free app.

for example, in-app purchase allow sell:

  • digital books or photos
  • additional game levels
  • access turn-by-turn map service
  • subscriptions digital magazines or newsletters
  • digital content hosted on apple servers

there 4 supported categories of in-app purchase items may sell: 1) content, 2) functionality, 3) services, , 4) subscriptions. must deliver digital or service within app. may not use in-app purchase sell real-world goods , services.

java - UML - How would you draw a try catch in a sequence diagram? -

Image
is there standard way of drawing try catch sequence diagrams? i've made attempt based on this feel end result doesn't feel right. code diagram based around: public static void save () { try { filehandle filehandle = gdx.files.external(file); filehandle.writestring(boolean.tostring(constantshandler.soundenabled)+"\n", false); (int = 0; < 5; i++) { filehandle.writestring(integer.tostring(constantshandler.highscores[i])+"\n", true); } } catch (throwable e) { } } my attempt note: know still need add loop. that's ok. fragments meant show conditional control flow in sequence diagram. superstructures puts limitations on use of fragments (see pp. 467 of ss2.1.1). should use critical region try part above. , option catch . however, keep telling can take quite freedom in using uml. it's language , such changes in life time. long reader ge...
