@VisibleForTesting
@DeprecatedSinceApi(api = 28, message = "Use the SigningInfo based constructor instead")
CallingAppInfo(
    packageName: String,
    signatures: List<Signature>,
    origin: String? = null
)

Constructs an instance of CallingAppInfo

Parameters
packageName: String

the calling package name of the calling app

signatures: List<Signature>

the app signatures, which should be retrieved from the app's PackageInfo.signatures

origin: String? = null

the origin of the calling app. This is only set when a privileged app like a browser, calls on behalf of another application.

Throws
kotlin.NullPointerException

If packageName is null

kotlin.NullPointerException

If the class is initialized with a null signingInfo on Android API 28 and above

kotlin.IllegalArgumentException

If packageName is empty

@VisibleForTesting
CallingAppInfo(
    packageName: String,
    signingInfo: SigningInfo,
    origin: String? = null
)

Constructs an instance of CallingAppInfo

Parameters
packageName: String

the calling package name of the calling app

signingInfo: SigningInfo

the signingInfo associated with the calling app

origin: String? = null

the origin of the calling app. This is only set when a privileged app like a browser, calls on behalf of another application.

Throws
kotlin.NullPointerException

If packageName is null

kotlin.NullPointerException

If the class is initialized with a null signingInfo on Android P and above

If packageName is empty

Public functions

equals

open operator fun equals(other: Any?): Boolean

getOrigin

Added in 1.2.0
fun getOrigin(privilegedAllowlist: String): String?

Returns the origin of the calling app. This is only non-null if a privileged app like a browser calls Credential Manager APIs on behalf of another application.

Additionally, in order to get the origin, the credential provider must provide an allowlist of privileged browsers/apps that it trusts. This allowlist must be in the form of a valid, non-empty JSON. The origin will only be returned if the packageName and the SHA256 hash of the newest signature obtained from the signingInfo, is present in the privilegedAllowlist.

Packages that are signed with multiple signers will only receive the origin if all of the signatures are present in the privilegedAllowlist.

The format of this privilegedAllowlist JSON must adhere to the following sample.

{"apps": [
{
"type": "android",
"info": {
"package_name": "com.example.myapp",
"signatures" : [
{"build": "release",
"cert_fingerprint_sha256": "59:0D:2D:7B:33:6A:BD:FB:54:CD:3D:8B:36:8C:5C:3A:
7D:22:67:5A:9A:85:9A:6A:65:47:FD:4C:8A:7C:30:32"
},
{"build": "userdebug",
"cert_fingerprint_sha256": "59:0D:2D:7B:33:6A:BD:FB:54:CD:3D:8B:36:8C:5C:3A:7D:
22:67:5A:9A:85:9A:6A:65:47:FD:4C:8A:7C:30:32"
}]
}
}
]}

All keys in the JSON must be exactly as stated in the sample above. Note that if the build for a given fingerprint is specified as 'userdebug', that fingerprint will only be considered if the device is on a 'userdebug' build, as determined by Build.TYPE.

Throws
kotlin.IllegalArgumentException

If privilegedAllowlist is empty, or an invalid JSON, or does not follow the format detailed above

kotlin.IllegalStateException

If the origin is non-null, but the packageName and signingInfo do not have a match in the privilegedAllowlist

hashCode

open fun hashCode(): Int

isOriginPopulated

Added in 1.2.0
fun isOriginPopulated(): Boolean

Returns true if the origin is populated, and false otherwise.

Note that the origin is only populated if a privileged app like a browser calls Credential Manager APIs on behalf of another application.
