İşte benimkini nasıl yaptım, biri deneme etkinliği olan diğeri olmadan 2 uygulama oluşturdum.
Mağazayı ücretli uygulama olarak oynamak için deneme etkinliği olmayan birini yükledim,
ve ücretsiz uygulama olarak deneme etkinliği olan.
İlk başlatıldığında ücretsiz uygulama, deneme ve mağaza satın alma seçeneklerine sahiptir, kullanıcı mağazadan satın almayı seçerse, kullanıcının satın alması için mağazaya yönlendirir, ancak kullanıcı denemeyi tıklarsa deneme etkinliğine götürür.
NB: @snctln gibi 3. seçeneği kullandım ama değişikliklerle
ilk olarak , cihaz saatine bağlı değildim, zamanımı db'ye deneme kaydını yapan php dosyasından aldım,
ikinci olarak , her bir cihazı benzersiz şekilde tanımlamak için cihazın seri numarasını kullandım,
son olarak , uygulama kendi zamanına değil sunucu bağlantısından dönen zaman değerine bağlıdır, bu nedenle sistem yalnızca cihaz seri numarası değiştirilirse engellenebilir, bu da bir kullanıcı için oldukça streslidir.
işte kodum burada (Deneme etkinliği için):

daha sonra ana etkinlikte, kalan gün sayısını izlemek için paylaşılan tercihi (deneme etkinliğinde oluşturulan yükleme tarihi) kullanıyorum ve günler bittiyse ana etkinlik kullanıcı arayüzünü, satın almaları için mağazaya götüren bir mesajla engelliyorum.
Burada gördüğüm tek olumsuz taraf, bir Rogue kullanıcısı ücretli uygulamayı satın alırsa ve Zender gibi uygulamalarla paylaşmaya karar verirse, dosya paylaşımı veya hatta apk dosyasını insanların ücretsiz indirmesi için doğrudan bir sunucuda barındırmasıdır. Ama eminim yakında bu yanıtı buna bir çözümle veya çözüme bağlantıyla düzenleyeceğim.
Umarım bu bir ruhu kurtarır ... bir gün
Mutlu Kodlama ...
