Línea de trabajo

Start in firebase-storage/src/main/java/com/google/firebase/storage/UploadTask.java, especially the cited sections around chunk sizing and progress updates. Trace when progress is emitted for a 48 MB upload and check for related tests in the storage module. Done means large Android uploads report progress often enough to avoid long gaps while preserving correct progress values.

Descripción

api: storage
[READ] Step 1: Are you in the right place?
[REQUIRED] Step 2: Describe your environment
  • Android Studio version: Rabbit
  • Firebase Component: Storage
  • Component version: 22.0.1
[REQUIRED] Step 3: Describe the problem

When users upload larger files, progress updates from firebase seem to stop, which causes the user to think the upload is stuck. The reason for this seems to be:

  1. The Android implementation of StorageTask only emits progress when a chunk finishes
  2. The chunk size doubles until it reaches 32mb

So a ~64mb file gets a final update around 32mb, then no further progress updates until the upload finishes. That's not an ideal user experience.

I haven't seen this behavior on iOS, so I assume there progress is based on fixed byte sizes or is time based, rather than the total size of the chunk.

Steps to reproduce:

Upload a 48mb file on Android
