Versions until 15.1 were called NanoMod, starting with 16.0 they're called NanoDroid.

The transistion in Magisk Mode installation between old and new module name is handled by the installer.

Snapshots

You can create snapshots from this repository.

• on GNU/Linux, MacOS or *BSD clone this repository and use the provided build-package script like
  • first step:
    • build-package pull to download all required apks for Full, microG and F-Droid package
  • second step:
    • build-package full to create the full package
    • build-package microg to create the microG only package
    • build-package fdroid to create the F-Droid only package
    • build-package patcher to create the on-device framework-patcher package
    • build-package uninstaller to create the uninstaller package
    • build-package setupwizard to create the Setup Wizard package
    • build-package all to create all packages at once
  • third step:
    • build-package u-microg to update microG
    • build-package u-fdroid to update F-Droid
    • build-package u-apps to update (most) applications
    • build-package u-swipe to update swipe libraries
    • build-package u-gsync to update Google Sync Adapters
    • build-package pull to update/re-download everything

for apks downloaded from F-Droid or microG repository or from APK Mirror, build-package checks the SHA256 hash.

The build-package script additionally supports the following parameters:

• check check if all files were properly downloaded
• clean remove any untracked files from the repo (e. g. from build-package pull)
• dalvik [.jar] prepare a jar file for use with DalvikVM
• ver [version] [date] change project version
• bump increment Magisk module version by 1

The following applications are custom builds:

• Play Store (reason: re-signed and modified to support (in-)app-purchases with microG GmsCore)
  • Download Link
• Fake Store (reason: built with CHECK_LICENSE permission)
  • Download Link
• MPV (reason: infrequent updates, merge-requests included)
  • Download Link

Also build-package looks if the configuration files

• .nanodroid-setup
• .nanodroid-apps
• .nanodroid-overlay

exist in the data directory of the repository, if so, those files are used when creating packages instead of the default ones from the doc directory.

See the documentation below for more information on those files and what they do.

Installation

Alter Installation

NanoDroid supports altering the installation settings to a wide degree.

Full > Details on altering installation manually, or use the Setup Wizard (if you've got an arm/arm64 device).

Installation Process

NanoDroid

• Use Setup Wizard to create configuration files (if you've got an arm/arm64 device), or create manually (see above)
• Download pre-built zip or create one from this repository
• perform full wipe (/system, /data, /cache, Dalvik/ART cache)
  • recommended, but not required
• install desired ROM
  • make sure it does not include GApps if you want to use microG
  • either pre-patched with signature spoofing support or deoxeded so you can patch yourself (instructions follow)
• install Magisk
  • recommended, but not required
  • if Magisk is installed, NanoDroid will be installed as Magisk-Module, else it will install into /system directly
• install desired Kernel (if any)
• install NanoDroid
• reboot into ROM

microG

Signature Spoofing Support

For microG to work, your ROM needs to have signature spoofing enabled (or a deodexed ROM to patch yourself).

If your ROM does not have signature spoofing support, you can manually patch it either

• flashing the on-device Patcher zip
  • it also installs an addon.d script that auto re-patches the ROM upon update
• running the framework-patcher script
  • use from your PC or laptop while your device is in TWRP. This shell script for GNU Bash (and compatible shells) works on unixoid operating systems like GNU/Linux, BSD or MacOS. It automizes the process of downloading Haystack > GitHub, pulling files from phone, patching and installing the modified services.jar on the device.

Both patchers support installing the patched services.jar into the following locations:

• NanoDroid Magisk Module
• NanoDroid-microG Magisk Module
• directly into /system

So you can use them regardless whether you're using NanoDroid or not.

microG Setup

Once your ROM supports signature spoofing, you need to setup microG like this

• go into microG settings and set up everything like:
  • check results in Self-Check, grant missing permissions (by tapping on them)
    • especially the Battery Optimization item
  • enable Google device registration
  • enable Google Cloud Messaging (only if you want to receive push messages from your applications)
  • enable Google SafetyNet (required for applications that utilize SafetyNet, for example Pokémon GO, ...)
    • '...' menu > set to use the Official Server
  • in UnifiedNlp Settings choose
    • Déjà Vu and/or Mozilla as Geolocation backend
    • Nominatim as Address lockup backend
  • after everything is done, reboot
  • go to Play Store, setup account and install your apps

Issues

List of known issues

• SafetyNet check fails with Google Play Services not available
  • you did not setup microG (or did not reboot afterwards)
• Battery Drain
  • microG fails to register applications to GCM (Google Cloud Messaging) if they were installed before microG, but the apps keep trying to register and that causes the battery drain, all apps installed after microG are properly registered, to fix the battery drain either
    • do a clean flash of your ROM (, Magisk) and NanoDroid and install your apps after microG setup
    • uninstall and re-install all your applications (backup application data if required)
• microG lacks features
  • if you use AppOps, PrivacyGuard or the like you have to grant microG GmsCore all permissions, if you prevent some permissions, some apps or features might not work as expected or not at all. Note: some APIs/features are stubs in microG GmsCore, meaning they exist that apps don't complain, but they do nothing - thus blocking microG GmsCore is pretty much of no benefit.

Additional helpful information in the microG > Wiki.

TODO

• better error handling in on-pc framework-patcher
• on-device de-odexing of services.jar in NanoDroid-Patcher
