boolean visible,
@NonNull PackageIdentifier packageIdentifier
)
Sets whether or not documents from the provided androidx.appsearch.annotation.Document annotated class can be read by the specified package.
Each package is represented by a PackageIdentifier, containing a package name and a byte array of type CERT_INPUT_SHA256.
To opt into one-way data sharing with another application, the developer will need to explicitly grant the other application’s package name and certificate Read access to its data.
For two-way data sharing, both applications need to explicitly grant Read access to one another.
By default, app data sharing between applications is disabled.

setForceOverride
public @NonNull SetSchemaRequest.Builder setForceOverride(boolean forceOverride)
Sets whether or not to override the current schema in the AppSearchSession database.
Call this method whenever backward incompatible changes need to be made by setting forceOverride to true. As a result, during execution of the setSchema operation, all documents that are incompatible with the new schema will be deleted and the new schema will be saved and persisted.
By default, this is false.
setMigrator
public @NonNull SetSchemaRequest.Builder setMigrator(@NonNull String schemaType, @NonNull Migrator migrator)
Sets the Migrator associated with the given SchemaType.
The Migrator migrates all GenericDocuments under given schema type from the current version number stored in AppSearch to the final version set via setVersion.
A Migrator will be invoked if the current version number stored in AppSearch is different from the final version set via setVersion and shouldMigrate returns true.
The target schema type of the output GenericDocument of onUpgrade or onDowngrade must exist in this SetSchemaRequest.
| Parameters | |
|---|---|
@NonNull String schemaType |
The schema type to set migrator on. |
@NonNull Migrator migrator |
The migrator translates a document from its current version to the final version set via |
setMigrators
public @NonNull SetSchemaRequest.Builder setMigrators(@NonNull Map<String, Migrator> migrators)
Sets a Map of Migrators.
The key of the map is the schema type that the Migrator value applies to.
The Migrator migrates all GenericDocuments under given schema type from the current version number stored in AppSearch to the final version set via setVersion.
A Migrator will be invoked if the current version number stored in AppSearch is different from the final version set via setVersion and shouldMigrate returns true.
The target schema type of the output GenericDocument of onUpgrade or onDowngrade must exist in this SetSchemaRequest.
setPubliclyVisibleDocumentClass
@RequiresFeature(enforcement = "androidx.appsearch.app.Features#isFeatureSupported", name = Features.SET_SCHEMA_REQUEST_SET_PUBLICLY_VISIBLE)
public @NonNull SetSchemaRequest.Builder setPubliclyVisibleDocumentClass(
@NonNull Class<Object> documentClass,
@Nullable PackageIdentifier packageIdentifier
)
Specify that the documents from the provided androidx.appsearch.annotation.Document annotated class should be publicly available, to packages which already have visibility to packageIdentifier. This visibility is determined by the result of canPackageQuery.
It is possible for the packageIdentifier parameter to be different from the package performing the indexing. This might happen in the case of an on-device indexer processing information about various packages. The visibility will be the same regardless of which package indexes the document, as the visibility is based on the packageIdentifier parameter.
If this is called repeatedly with the same androidx.appsearch.annotation.Document annotated class, the PackageIdentifier in the last call will be used as the "from" package for that class (or schema).
Calling this with packageIdentifier set to null is valid, and will remove public visibility for the class (or schema).
| Parameters | |
|---|---|
@NonNull Class<Object> documentClass |
the |
@Nullable PackageIdentifier packageIdentifier |
if an app can see this package via PackageManager#canPackageQuery, it will be able to see the documents of type |

)
Specify that the schema should be publicly available, to packages which already have visibility to packageIdentifier. This visibility is determined by the result of canPackageQuery.
It is possible for the packageIdentifier parameter to be different from the package performing the indexing. This might happen in the case of an on-device indexer processing information about various packages. The visibility will be the same regardless of which package indexes the document, as the visibility is based on the packageIdentifier parameter.
If this is called repeatedly with the same schema, the PackageIdentifier in the last call will be used as the "from" package for that schema.
Calling this with packageIdentifier set to null is valid, and will remove public visibility for the schema.

setSchemaTypeDisplayedBySystem
public @NonNull SetSchemaRequest.Builder setSchemaTypeDisplayedBySystem(
@NonNull String schemaType,
boolean displayed
)
Sets whether or not documents from the provided schemaType will be displayed and visible on any system UI surface.

setSchemaTypeVisibilityForPackage
public @NonNull SetSchemaRequest.Builder setSchemaTypeVisibilityForPackage(
@NonNull String schemaType,
boolean visible,
@NonNull PackageIdentifier packageIdentifier
)
Sets whether or not documents from the provided schemaType can be read by the specified package.
Each package is represented by a PackageIdentifier, containing a package name and a byte array of type CERT_INPUT_SHA256.
To opt into one-way data sharing with another application, the developer will need to explicitly grant the other application’s package name and certificate Read access to its data.
For two-way data sharing, both applications need to explicitly grant Read access to one another.
By default, data sharing between applications is disabled.
The relationship between permissions added in this method and package visibility setting setSchemaTypeVisibilityForPackage is "OR". The caller could access the schema if they match ANY requirements. If you want to set "AND" requirements like a caller must hold required permissions AND it is a specified package, please use addSchemaTypeVisibleToConfig.
| Parameters | |
|---|---|
@NonNull String schemaType |
The schema type to set visibility on. |
boolean visible |
Whether the |
@NonNull PackageIdentifier packageIdentifier |
Represents the package that will be granted visibility. |
setVersion
public @NonNull SetSchemaRequest.Builder setVersion(@IntRange(from = 1) int version)
Sets the version number of the overall AppSearchSchema in the database.
The AppSearchSession database can only ever hold documents for one version at a time.
Setting a version number that is different from the version number currently stored in AppSearch will result in AppSearch calling the Migrators provided to setSchemaAsync to migrate the documents already in AppSearch from the previous version to the one set in this request. The version number can be updated without any other changes to the set of schemas.
The version number can stay the same, increase, or decrease relative to the current version number that is already stored in the AppSearchSession database.
The version of an empty database will always be 0. You cannot set version to the SetSchemaRequest, if it doesn't contains any AppSearchSchema.
| Parameters | |
|---|---|
@IntRange(from = 1) int version |
A positive integer representing the version of the entire set of schemas represents the version of the whole schema in the |
| Throws | |
|---|---|
java.lang.IllegalArgumentException |
if the version is negative. |
