Start with the repository README and locate the Android flow responsible for submitting tree data; the issue does not name specific files or tests. Review how the app handles GPS, timestamps, images, descriptions, offline buffering, and blockchain invocation. Done means submissions reach CreateTree with Pending state and provide confirmation after successful submission.
