IMPORTANT: In July 2025, we stopped releasing new versions of KTX modules, and we removed the KTX libraries from the Firebase Android BoM (v34.0.0). If you use KTX APIs from the previously released KTX modules, we recommend that you migrate your app to use KTX APIs from the main modules instead. For details, see the FAQ about this initiative.

GroundingSupport

public final class GroundingSupport

Provides information about how a specific segment of the model's response is supported by the retrieved grounding chunks.

Summary

Public fields
`final @NonNull List<@NonNull Integer>`	`groundingChunkIndices` A list of indices that refer to specific `GroundingChunk` classes within the `GroundingMetadata.groundingChunks` array.
`final @NonNull Segment`	`segment` Specifies the segment of the model's response content that this grounding support pertains to.

Public constructors
`GroundingSupport( @NonNull Segment segment, @NonNull List<@NonNull Integer> groundingChunkIndices )`

Public fields

groundingChunkIndices

public final @NonNull List<@NonNull Integer> groundingChunkIndices

A list of indices that refer to specific GroundingChunk classes within the GroundingMetadata.groundingChunks array. These referenced chunks are the sources that support the claim made in the associated segment of the response. For example, an array [1, 3, 4] means that groundingChunks[1], groundingChunks[3], groundingChunks[4] are the retrieved content supporting this part of the response.

segment

public final @NonNull Segment segment

Specifies the segment of the model's response content that this grounding support pertains to.
