So, this is a simple app to change your Android ID.

It is on Google Play for £4.99 (VAT included by Google, so will be more), so please buy it if you want, however it is attached for all XDA members to use free of charge!

This app uses the secure settings API to write the ANDROID_ID, and it grants itself the relevant permission using the package manager executable.

It has a backup function as well, as well as the ability to generate a random ID.

Play Link: https://play.google.com/store/apps/d...droididchanger.

Feel free to provide feedback!

It will be on Google Play for £1.50, so please buy it if you want, however it is attached for all xda members to use free of charge!

*This app doesn't directly modify the database. It uses the in built write secure settings API. As such it must be a system app*

It has a backup function as well.

(I only just uploaded it so it may take a few hours...)


Feel free to provide feedback!

Known Bugs:

* Backup isn't made unless /sdcard/idchanger/backup is created manually


What is the purpose for this? What does this actually do? What ID are you changing?

The ANDROID_ID that is a unique ID for all Android devices, which is null on some devices.

This app changes a unique ID, as liamwli explained -- Google uses it to identify your device. Since it may change upon installation of another ROM, you may want to revert to the previous ID to prevent several new entries cropping up on the Play Store device menu, for example (in the menu where your devices are listed whenever you (buy and) install an application or game). This tends to get a big mess over time with us OCD flashers, and this means you will have to find out by chance or elimination whatever device Google thinks you are currently on is the device you intend to install to.

EDIT: Oh, and Google's application copy protection scheme seems to partly rely on it, although there are not that many developers depending on this.

Does the Play Store rely on ANDROID_ID for app compatibility? If I change this, will I be able to download apps saying "Not compatible with your device"?

No, that is gathered from XML files on the device and is sent to the Google servers during setup.

Uses the Android API to write the secure setting. Needs to be a system app, which is why it needs root.
