Seedvault

A backup application for the Android Open Source Project.

If you are having an issue/question, please look at our FAQ.

Components

Local Contacts Backup - an app that backs up local on-device contacts
Storage library - a library handling efficient backup of files
Seedvault app - the main app where all functionality comes together

Features

Backup application data to a flash drive.
Restore application data from a flash drive.
User-friendly encryption using a mnemonic phrase (BIP39).
Automatic daily backups that run in the background.

Requirements

SeedVault is developed alongwith AOSP releases

We update it every time Google releases a new Android version, make any changes required for basic functionality, and any improvements possible through API changes in the OS.

This means that for ROMs using SeedVault it's recommended to use the same branch as your android version

This current branch android13 is meant for usage with Android 13
This is indicated by the version name starting with 13, and the version code starting with 33 - the Android 13 API version

For older versions of Android, check out the branches.

Trying to use an older branch on a newer version may lead to issues and is not something we can support.

Getting Started

Check out the wiki for information on building the application with AOSP.

What makes this different?

This application is compiled with the operating system and does not require a rooted device for use. It uses the same internal APIs as adb backup which is deprecated and thus needs a replacement.

android.permission.ACCESS_NETWORK_STATE to check if there is internet access when network storage is used.
