Defines the constants used in a response from a Font Provider. The cursor returned from the query should have the ID column populated with the content uri ID for the resulting font. This should point to a real file or shared memory, as the client will mmap the given file descriptor. Pipes, sockets and other non-mmap-able file descriptors will fail to load in the client application.

## Constants

### FILE_ID

Added in [1.1.0](https://developer.android.com/jetpack/androidx/releases/core#1.1.0)

```
public static final String FILE_ID = "file_id"
```

Constant used to request data from a font provider. The cursor returned from the query may populate this column with a long for the font file ID. The client will request a file descriptor to "file/FILE_ID" with this ID immediately under the top-level content URI. If not present, the client will request a file descriptor to the top-level URI with the given base font ID. Note that several results may return the same file ID, e.g. for TTC files with different indices.

### ITALIC

Added in [1.1.0](https://developer.android.com/jetpack/androidx/releases/core#1.1.0)

```
public static final String ITALIC = "font_italic"
```

Constant used to request data from a font provider. The cursor returned from the query should have this column populated with the int italic for the resulting font. This should be 0 for regular style and 1 for italic.

### RESULT_CODE

Added in [1.1.0](https://developer.android.com/jetpack/androidx/releases/core#1.1.0)

```
public static final String RESULT_CODE = "result_code"
```

Constant used to request data from a font provider. The cursor returned from the query should have this column populated to indicate the result status of the query. This will be checked before any other data in the cursor. Possible values are `https://developer.android.com/reference/androidx/core/provider/FontsContractCompat.Columns#RESULT_CODE_OK()`, `https://developer.android.com/reference/androidx/core/provider/FontsContractCompat.Columns#RESULT_CODE_FONT_NOT_FOUND()`, `https://developer.android.com/reference/androidx/core/provider/FontsContractCompat.Columns#RESULT_CODE_MALFORMED_QUERY()` and `https://developer.android.com/reference/androidx/core/provider/FontsContractCompat.Columns#RESULT_CODE_FONT_UNAVAILABLE()`. If not present, `https://developer.android.com/reference/androidx/core/provider/FontsContractCompat.Columns#RESULT_CODE_OK()` will be assumed.

### RESULT_CODE_FONT_NOT_FOUND
