问题
I create a new bucket in a region near from my users location (asia-southeast1) so hopefully it will fetch the image faster in the client side, I want to upload image and also to download image from that new bucket.
but I don't how to make reference to that new bucket. usually I use the code below in Android to create reference for default bucket
val ref = FirebaseStorage.getInstance().reference.child("profilePicture")
so how to download and upload image from that bucket? I assume that I have to make some change when creating the reference, but I don't know how to pointing the reference to that new bucket
回答1:
In the API documentation for FirebaseStorage, it says:
FirebaseStorage is a service that supports uploading and downloading large objects to Google Cloud Storage. Pass a custom instance of FirebaseApp to getInstance(FirebaseApp) which will initialize it with a storage location (bucket) specified via setStorageBucket(String).
Otherwise, if you call getReference() without a FirebaseApp, the FirebaseStorage instance will initialize with the default FirebaseApp obtainable from getInstance(). The storage location in this case will come the JSON configuration file downloaded from the web.
The bolded text is what you will need to do. Initialize a new FirebaseApp instance using a FirebaseOptions object using a builder where you called setStorageBucket() with the name of the bucket you want to use.
Then, when you call FirebaseStorage.getInstance(app), passing that FirebaseApp instance, your references will come from that bucket.

After getting info from @samthecodingman and testing it, I can set a reference to use a certain bucket using the code below
FirebaseStorage.getInstance("gs://yourBucketNameHere").reference.child("profilePicture")
Don't forget to add gs:// in your string as documented here.
