member this.Query : Android.Net.Network * string * Android.Net.DnsResolverFlag * Java.Util.Concurrent.IExecutor * Android.OS.CancellationSignal * Android.Net.DnsResolver.ICallback -> unitParameters
- network
- Network
Network specifying which network to query on. null for query on default network.
- domain
- String
domain name to query. This value cannot be null.
- flags
- DnsResolverFlag
flags as a combination of the FLAGS_* constants. Value is one of the following: FLAG_EMPTY; FLAG_NO_RETRY; FLAG_NO_CACHE_STORE; FLAG_NO_CACHE_LOOKUP
- executor
- IExecutor
The Executor that the callback should be executed on. This value cannot be null. Callback and listener events are dispatched through this Executor, providing an easy way to control which thread is used. To dispatch events through the main thread of your application, you can use Context.getMainExecutor(). Otherwise, provide an Executor that dispatches to an appropriate thread.
- cancellationSignal
- CancellationSignal
used by the caller to signal if the query should be cancelled. May be null.
- callback
- DnsResolver.ICallback
a Callback which will be called to notify the caller of the result of dns query. This value cannot be null.

- network
- Network
Network specifying which network to query on. null for query on default network.
- domain
- String
domain name to query. This value cannot be null.

flags as a combination of the FLAGS_* constants. Value is one of the following: FLAG_EMPTY; FLAG_NO_RETRY; FLAG_NO_CACHE_STORE; FLAG_NO_CACHE_LOOKUP
- executor
- IExecutor
The Executor that the callback should be executed on. This value cannot be null. Callback and listener events are dispatched through this Executor, providing an easy way to control which thread is used. To dispatch events through the main thread of your application, you can use Context.getMainExecutor(). Otherwise, provide an Executor that dispatches to an appropriate thread.
- httpsTimeoutMillis
- Int32
the timeout in milliseconds to wait for the HTTPS query to complete after the A/AAAA queries have already completed. May be set to HTTPS_QUERY_WAIT_NONE to disable any additional wait, HTTPS_QUERY_WAIT_AUTO to use the default wait time, HTTPS_QUERY_WAIT_UNTIL_TIMEOUT to wait for the HTTPS query to complete, or a specific value in milliseconds.
- cancellationSignal
- CancellationSignal
used by the caller to signal if all the queries should be cancelled. May be null.
- callback
- DnsResolver.ICallback
a Callback which will be called to notify the caller of the results of the A/AAAA/HTTPS DNS queries. Will return a ERROR_PARSE if any of the DNS records cannot be parsed, and should be treated as a resolution failure. This value cannot be null.
- Attributes
Remarks
Send concurrent A/AAAA/HTTPS DNS queries with the specified name on a network. The answer to all queries will be provided asynchronously through the provided callback Callback, which provides a HttpsEndpoint.
