Public constructors

ExifInterface

Added in API level 5
ExifInterface (String filename)

Reads Exif tags from the specified image file.

Parameters
filename String
Throws
IOException

ExifInterface

Added in API level 24
ExifInterface (FileDescriptor fileDescriptor)

Reads Exif tags from the specified image file descriptor. Attribute mutation is supported for writable and seekable file descriptors only. This constructor will not rewind the offset of the given file descriptor. Developers should close the file descriptor after use.

Parameters
fileDescriptor FileDescriptor
Throws
IOException

ExifInterface

Added in API level 24
ExifInterface (InputStream inputStream)

Reads Exif tags from the specified image input stream. Attribute mutation is not supported for input streams. The given input stream will proceed its current position. Developers should close the input stream after use.

Parameters
inputStream InputStream
Throws
IOException

Public methods

getAltitude

Added in API level 9
double getAltitude (double defaultValue)

Return the altitude in meters. If the exif tag does not exist, return defaultValue.

Parameters
defaultValue double: the value to return if the tag is not available.
Returns
double

getAttribute

Added in API level 5
String getAttribute (String tag)

Returns the value of the specified tag or null if there is no such tag in the image file.

Parameters
tag String: the name of the tag.
Returns
String

getAttributeDouble

Added in API level 8
double getAttributeDouble (String tag, 
                double defaultValue)

Returns the double value of the tag that is specified as rational or contains a double-formatted value. If there is no such tag in the image file or the value cannot be parsed as double, return defaultValue.

Parameters
tag String: the name of the tag.
defaultValue double: the value to return if the tag is not available.
Returns
double

getAttributeInt

Added in API level 5
int getAttributeInt (String tag, 
                int defaultValue)

Returns the integer value of the specified tag. If there is no such tag in the image file or the value cannot be parsed as integer, return defaultValue.

Parameters
tag String: the name of the tag.
defaultValue int: the value to return if the tag is not available.
Returns
int

getLatLong

Added in API level 5
boolean getLatLong (float[] output)

Stores the latitude and longitude value in a float array. The first element is the latitude, and the second element is the longitude. Returns false if the Exif tags are not available.

Parameters
output float
Returns
boolean

getThumbnail

Added in API level 5
byte[] getThumbnail ()

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

Returns
byte[]

getThumbnailRange

Added in API level 24
long[] getThumbnailRange ()

Returns the offset and length of thumbnail inside the image file, or null if there is no thumbnail.

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

hasThumbnail

Added in API level 5
boolean hasThumbnail ()

Returns true if the image file has a thumbnail.

Returns
boolean

saveAttributes

Added in API level 5
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(String, String) to set all attributes to write and make a single call rather than multiple calls for each attribute.

Throws
IOException

setAttribute

Added in API level 5
void setAttribute (String tag, 
                String value)

Set the value of the specified tag.

Parameters
tag String: the name of the tag.
value String: the value of the tag.
