Delete files with Cloud Storage on Android

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! 
 } 
   StorageActivity 
 .

Java

 // Create a storage reference from our app 
 StorageReference

 StorageReference 
  
 desertRef 
  
 = 
  
 storageRef

 child 
 ( 
 "images/desert.jpg"

 { 
  
 // File deleted successfully

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.
