This is an example of how to list the files stored in a given Storage Bucket (like a "folder") in Java under Android.
For the detailed description of
listing files (the example listed there uses Kotlin, not Java).
final String LOG_TAG = "MyTag"
// The first step in accessing your storage bucket is to create an instance of FirebaseStorage:
FirebaseStorage storage = FirebaseStorage.getInstance();
// ... or you also can specify a specific storage bucket (see document from the first URL from above)
// FirebaseStorage storage = FirebaseStorage.getInstance("gs://my-custom-bucket");
// Create a storage reference from our app
StorageReference storageRef = storage.getReference();
// Create a child reference. The myKindOfFolder now points to the "kind of subdirectory" containing the file(s) to be listed
storageRef.child("myKindOfFolder")
.listAll()
.addOnSuccessListener(new OnSuccessListener<ListResult>() {
@Override
public void onSuccess(@NonNull ListResult result) {
Log.d(LOG_TAG, "onSuccess()");
Iterator<StorageReference> i = result.getItems().iterator();
StorageReference ref;
while (i.hasNext()) {
ref = i.next();
Log.d(LOG_TAG, "onSuccess() File name: " + ref.getName());
}
}
})
.addOnFailureListener(new OnFailureListener() {
public void onFailure(@NonNull Exception e) {
Log.er(LOG_TAG, "onFailure(): ", e);
}
});
