Hello everyone.
Migrate 3.0 is now released (without alpha)

From now on, there will be two editions of Migrate.

Migrate NG: This is the Non-Google and Beta edition. It is not published on Google Play store. It will continue having in-app updates. Moreover new features will be tested on these builds first. People who did not like firebase analytics, this edition is for you as it does not have firebase SDK anymore. However, Google admob ads are still present.

Migrate GPE: This version is Google Play Edition. It is the stable version. It does not have in-app updates anymore as it violated Google Play policies.

Coming from alpha 3.1, if you update via the in-app updater, you will be switched to the Non-Google Edition.

Hello everyone. I have an important announcement.

Since the beginning of this application, Migrate has been relying on TWRP to flash backups. This has been convenient for most users, but not for all. TWRP has not been successful in many cases and there have been complex workarounds like manual_restore method.

This had to be changed. As such, I am presenting Migrate's sister app: Migrate Flasher

1. This app can be used to flash only migrate backup zips without needing to boot TWRP.
2. For actual app restore, the Migrate helper is still needed. This just is an alternative to TWRP.
3. Flashing via TWRP will still be supported for the foreseeable future.
4. This app is still incomplete (not even in alpha stage). I am sharing so that adventures people may try it and give me feedback.
5. You cannot flash any other Mod/ROM using this app.
TAKE A NANDROID BACKUP AND STORE IN YOUR PC BEFORE TRYING (in case anything goes wrong)

Migrate Flasher is now published on Google Play with improvements

Read the app description to know more.

[Android 11] Migrate 4.0 Gemini is now available for Migrate-NG users as BETA

To get the update, go to Preferences -> Select update channel -> Beta+stable

Then go back and check for updates.

Migrate-GPE users may try out the apk from here.

Feedback appreciated. If all goes well, it will be published on Google Play store soon.
Kindly take a nandroid backup before trying.

Migrate 4.0 is released on Google Play Store.

Important info for Migrate-NG beta users: there is a bug in the downloader causing it to crash. You will need to manually download the apk and install. Available on XDA labs / AFH

The biggest problem in pushing the next version update of Migrate is Scoped Storage.
Read the problems of it here: https://www.xda-developers.com/android-q-storage-access-framework-scoped-storage/

More explanation from a programming standpoint:
========================
While designing the app, I had never thought that Google will deprecate such a basic thing like Java File. Migrate extensively relies on it and moving from File to a Uri based approach would be a huge trouble. As migrate uses shell scripts, hence raw file paths are absolutely necessary.

Hence I set out to write a library that eases the transformation process. Meet FileX.
https://github.com/SayantanRC/FileX

This library uses DocumentsContract in background, handles all the Uri related stuff and provides familiar functions and fields like mkdirs(), createNewFile(), copyRecursively() etc.

This is an open source library, it is nowhere near stable, but if anyone wants, they can give it a try in their apps. Constructive feedback is welcome.
========================

How does it impact the users?
========================
1. If the FileX library works as intended, Migrate should get native support to backup on SD cards and USB OTG drives.

2. Backups will be much slower than before. It is because Scoped Storage is inherently slow. Depending on ROMs, it may even be more unstable than before; have to wait and see how it plays out...

3. Since Migrate-NG is not distributed via Google Play store, it will continue to offer the current default backup method (under [Internal storage]/Migrate) along with FileX (best of both worlds). Migrate-GPE however, has to target Android 11 and above (blame Google), hence using FileX will be the only option.
========================

🎉 Migrate is back from the dead. A new version v6 is approved by Google.

https://play.google.com/store/apps/details?id=balti.migrate

#️⃣ The app has been completely rewritten. There are changes to the vision of the project moving forward - including support for non-root users and license changes. Currently the app is incomplete but you can do basic things like backup and restore of contacts, call logs and SMS.

⛔ Some features removed like backup zip creation and TWRP support. App backup and other backups which required root access, are not yet available but will be added in a future release.

🔮 New features are being planned like calendar backup and scheduled backups.
