After uploading files to Cloud Storage, you can also delete them.
Delete a File
To delete a file, first create a reference to that file. Then call the delete() method on that reference.
Kotlin
// Create a storage reference from our app val storageRef = storage.reference // Create a reference to the file to delete val desertRef = storageRef.child("images/desert.jpg") // Delete the file desertRef.delete().addOnSuccessListener { // File deleted successfully }.addOnFailureListener { // Uh-oh, an error occurred! }
Java
// Create a storage reference from our app StorageReference storageRef = storage.getReference(); // Create a reference to the file to delete StorageReference desertRef = storageRef.child("images/desert.jpg"); // Delete the file desertRef.delete().addOnSuccessListener(new OnSuccessListener<Void>() { @Override public void onSuccess(Void aVoid) { // File deleted successfully } }).addOnFailureListener(new OnFailureListener() { @Override public void onFailure(@NonNull Exception exception) { // Uh-oh, an error occurred! } });
Handle Errors
There are a number of reasons why errors may occur on file deletes, including the file not existing, or the user not having permission to delete the specified file. More information on errors can be found in the Handle Errors section of the docs.
