Android - Use fallback paywalls

To use fallback paywalls:

1. Place the fallback JSON file you downloaded in the Adapty Dashboard alongside your app in the user's device.
2. Call the .setFallbackPaywalls method. Place this method in your code before fetching a paywall, ensuring that the mobile app possesses it when a fallback paywall is required to replace the standard one.

Here's an example of retrieving fallback paywall data from locally stored JSON file named android_fallback.json.

Kotlin

//if you put the 'android_fallback.json' file to the 'assets' directory
val location = FileLocation.fromAsset("android_fallback.json")
//or `FileLocation.fromAsset("<additional_folder>/android_fallback.json")` if you placed it in a child folder of 'assets')

//if you put the 'android_fallback.json' file to the 'res/raw' directory
val location = FileLocation.fromResId(context, R.raw.android_fallback)

//pass the file location
Adapty.setFallbackPaywalls(location, callback)

Java

//if you put the 'android_fallback.json' file to the 'assets' directory
FileLocation location = FileLocation.fromAsset("android_fallback.json");
//or `FileLocation.fromAsset("<additional_folder>/android_fallback.json");` if you placed it in a child folder of 'assets')

//if you put the 'android_fallback.json' file to the 'res/raw' directory
FileLocation location = FileLocation.fromResId(context, R.raw.android_fallback);

//pass the file location
Adapty.setFallbackPaywalls(location, callback);

Parameters:

Parameter	Description
location	The FileLocation for the file with fallback paywalls

Alternatively, you can use a URI instead of the file location. here is an example of how to do so:

Kotlin

val fileUri: Uri = //get Uri for the file with fallback paywalls
// for example, if you put the 'android_fallback.json' file to 'res/raw' directory,
// you can obtain the Uri as follows:
//
// val fileUri = Uri.Builder()
//    .scheme(ContentResolver.SCHEME_ANDROID_RESOURCE)
//    .authority(yourAuthority) //usually your applicationId
//    .appendPath("${R.raw.android_fallback}")
//    .build()

Adapty.setFallbackPaywalls(fileUri, callback)

Java

Uri fileUri = //get Uri for the file with fallback paywalls
// for example, if you put the 'android_fallback.json' file to 'res/raw' directory,
// you can obtain the Uri as follows:
//
// Uri fileUri = new Uri.Builder()
//    .scheme(ContentResolver.SCHEME_ANDROID_RESOURCE)
//    .authority(yourAuthority) //usually your applicationId
//    .appendPath(String.valueOf(R.raw.android_fallback))
//    .build();

Adapty.setFallbackPaywalls(fileUri, callback);

Parameters:

Parameter	Description
fileUri	The Uri for the file with fallback paywalls
