I am using in-app billing (com.android.billingclient:[email protected]:2) lib for payment in Android.
Billing Library: Provides product detail information as ProductDetails in response of QueryInventory.
I am storing those product detail information in session as JSON string using Gson Lib.
JSON String
{
"zza": "{\"productId\":\"com.abc.xyz\",\"type\":\"inapp\",\"title\":\"One-Time Purchase \",\"name\":\"One-Time Purchase\",\"description\":\"One-Time Purchase and Get premium content\",\"localizedIn\":[\"en-US\"],\"skuDetailsToken\":\"AEuhp4L1zoq6cjMTf8R2UF1nkG69D_MsfpoBqHySShV1u0cU5_NuObiMwl\",\"oneTimePurchaseOfferDetails\":{\"priceAmountMicros\":2900000000,\"priceCurrencyCode\":\"INR\",\"formattedPrice\":\"₹2,900.00\"}}",
"zzb": {
"nameValuePairs": {
"productId": "com.abc.xyz",
"type": "inapp",
"title": "One-Time Purchase",
"name": "One-Time Purchase",
"description": "One-Time Purchase and Get premium content",
"localizedIn": {
"values": [
"en-US"
]
},
"skuDetailsToken": "AEuhp4L1zoq6cjMTf8R2UF1nkG69D_MsfpoBqHySShV1u0cU5_NuObiMwl",
"oneTimePurchaseOfferDetails": {
"nameValuePairs": {
"priceAmountMicros": 2900000000,
"priceCurrencyCode": "INR",
"formattedPrice": "₹2,900.00"
}
}
}
},
"zzc": "com.abc.xyz",
"zzd": "inapp",
"zze": "One-Time Purchase",
"zzf": "One-Time Purchase",
"zzg": "One-Time Purchase and Get premium content",
"zzh": "AEuhp4L1zoq6cjMTf8R2UF1nkG69D_MsfpoBqHySShV1u0cU5_NuObiMwl",
"zzi": "",
"zzj": "",
"zzk": "",
"zzm": [
{
"zza": "₹2,900.00",
"zzb": 2900000000,
"zzc": "INR",
"zzd": "",
"zze": "",
"zzf": []
}
]
}
Now, I have created same ProductDetails object from JSON using Gsonlib.
But I am getting LinkedTreeMap casting exception while trying to get oneTimePurchaseOfferDetails info.

What I can see so far is use of similar variable names again and again throughout the code snippet. It is making it confusing to see where the thing is going wrong but I would suggest you to make use of generics in the Lists defined if you are only going to have a single Object type inside. For example: Define zzm as
instead of:
This will make it sure that this.zzm.get(0) in the getOneTimePurchaseOfferDetails() method will fetch you an object of ProductDetails.OneTimePurchaseOfferDetails type only and if you are by any chance trying to add a different kind of object to the list, you won't be able to at all.
If it still doesn't work, please let me know.
