Sync To Android Data

An Android utility app to allow file synchronization within the Android/data directory.

🖼️ Background

Since Android 11, the Android/data directory has been locked down by the new scoped storage paradigm. Standard file explorers and sync solutions (like OneDrive, Syncthing, or Dropbox) can no longer access these folders. This makes it nearly impossible to automatically sync game saves or app data/configuration to the cloud/self-hosted servers for apps that store data in this directory.

Sync To Android Data leverages Shizuku to automate file transfer to and from locations in Android/data, enabling data for these previously-restricted apps to be synchronized. Defined "Sync Entries" automatically move files between these restricted internal folders and a standard external folder of your choice when the "target app" is opened or closed.

📦 Installation

1. Go to the latest release.
2. Download sync-to-android-data.apk.
3. Install the APK on your Android device.
4. Use the built-in wizard to setup the app, including installation of Shizuku and all other prerequisites.

⚙️ How it Works

• Sync Entries contain configuration for each app you intend to keep data in sync for.
  • 
• Target Apps within Sync Entries define which package will be monitored for open and close by the sync engine (the app you intend to keep data in sync for).
  • 
• Directory Pairs within Sync Entries define which directories will be kept in sync based on the targeted application. Multiple Directory Pairs can be created for each Sync Entry.
  • External Directories within Directory Pairs define the location to be used as a source when the Target App is opened (External -> Internal sync occurs). Typically, these are directories that are accessible to your cloud storage/sync application.
  • Internal Directories within Directory Pairs define the location to be used as a source when the Target App is closed (Internal -> External sync occurs). Typically, these are directories within the Target App's respective folder in Android/data.
