Il vostro esempio è basato sul diritto documentazione ufficiale sono riuscito a far funzionare il Preapp ma fa schifo. Sto usando un'app Web per ottenere la chiave di approvazione da paypal (questa parte è OK). Riceve la chiave e reindirizza la risposta ad Android. Ora, su Android, sto usando un Obj PayPalPreapproval e ho impostato il suo preappkey come chiave preapp appena recuperata. Quando provo a invocare 'PayPal.getInstance(). SetPreapprovalKey (result); Inten preapproveIntent = PayPal.getInstance(). Preapprove (pre-approvazione, getBaseContext()); startSubActivity (preapproveIntent, 0); ' ho ottenuto un Err – kaffein
prima devi prendere una cassa da oggetto PayPalPayment e poi prendere un checkout –
Non so come ottenere un'approvazione preventiva chiave –
