ExifInterface

public class ExifInterface
extends Object

java.lang.Object
↳	android.media.ExifInterface

This is a class for reading and writing Exif tags in various image file formats.

Supported for reading: JPEG, PNG, WebP, HEIF, DNG, CR2, NEF, NRW, ARW, RW2, ORF, PEF, SRW, RAF, AVIF.

Supported for writing: JPEG, PNG, WebP.

Note: JPEG and HEIF files may contain XMP data either inside the Exif data chunk or outside of it. This class will search both locations for XMP data, but if XMP data exist both inside and outside Exif, will favor the XMP data inside Exif over the one outside.

Note: It is recommended to use the AndroidX ExifInterface Library since it is a superset of this class. In addition to the functionalities of this class, it supports parsing extra metadata such as exposure and data compression information as well as setting extra metadata such as GPS and datetime information.

Returns
`long[]`	two-element array, the offset in the first value, and length in the second, or `null` if no tag was found.

Throws
`IllegalStateException`	if `saveAttributes()` has been called since the underlying file was initially parsed, since that means offsets may have changed.

getDateTime

Returns parsed TAG_DATETIME value, or -1 if unavailable or invalid.
Value is a non-negative timestamp measured as the number of milliseconds since 1970-01-01T00:00:00Z.

getDateTimeDigitized

public long getDateTimeDigitized ()

Returns parsed TAG_DATETIME_DIGITIZED value, or -1 if unavailable or invalid.
Value is a non-negative timestamp measured as the number of milliseconds since 1970-01-01T00:00:00Z.

Returns
`long`	Value is a non-negative timestamp measured as the number of milliseconds since 1970-01-01T00:00:00Z.

`boolean`

getThumbnail

Returns the JPEG compressed thumbnail inside the image file, or null if there is no JPEG compressed thumbnail. The returned data can be decoded using BitmapFactory.decodeByteArray(byte[], int, int)

Returns
`byte[]`

getThumbnailBitmap

public Bitmap getThumbnailBitmap ()

Creates and returns a Bitmap object of the thumbnail image based on the byte array and the thumbnail compression value, or null if the compression type is unsupported.

Returns true if thumbnail image is JPEG Compressed, or false if either thumbnail image does not exist or thumbnail image is uncompressed.

Returns
`boolean`

saveAttributes

public void saveAttributes ()

Save the tag data into the original image file. This is expensive because it involves copying all the data from one file to another and deleting the old file and renaming the other. It's best to use setAttribute(java.lang.String, java.lang.String) to set all attributes to write and make a single call rather than multiple calls for each attribute.

This method is supported for JPEG, PNG and WebP files.

Note: after calling this method, any attempts to obtain range information from getAttributeRange(java.lang.String) or getThumbnailRange() will throw IllegalStateException, since the offsets may have changed in the newly written file.

For WebP format, the Exif data will be stored as an Extended File Format, and it may not be supported for older readers.

Throws
`IOException`

setAttribute

public void setAttribute (String tag, 
                String value)

Set the value of the specified tag.

Parameters
`tag`	`String`: the name of the tag. This value cannot be `null`.
`value`	`String`: the value of the tag. This value may be `null`.
