NanoDroid

NanoDroid is a installer for various OpenSource related things, most noticably microG and F-Droid. It supports direct /system installation, both devices with or without A/B partition scheme, aswell as Magisk Mode (module) installation. It also includes several tools (eg. GNU Bash, GNU Nano, more), scripts, fonts, sounds and additional features (system debloating, init scripts, automatic logcat creation), aswell as a companion F-Droid Repository.

Furthermore it allows the user to do fine-graded installations using configuration files, which allow to choose what to install, or if several alternatives are available, which of them, see Alter Installation below.

NanoDroid allows you to choose between the official microG GmsCore and a custom microG GmsCore (default), list of changes.

In order for full microG experience NanoDroid contains a modified Play Store which allows (in-)app-purchases with microG, which would normally not be possible. It also tries to remove all previously installed GApps on it's own. For ROMs without builtin signature spoofing support NanoDroid includes an on-device Patcher which tries to patch your ROM from TWRP.

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

SHA256 Checksum and GPG Signature

Since version 18.3.1 all releases hosted on nanolx.org contain a SHA256 checksum and GPG signature to check their validity. AFH does provide the SHA256 checksum on the downloads summary page, but does not allow to upload a GPG signature.

You can obtain the public part of my GPG key from:

  • download the public key from photonic.asc
    • import it using gpg --import photonic.asc
  • download and import using gpg from pgp.mit.edu:
    • gpg --keyserver pgp.mit.edu --recv B0ABCE622A077B584B81339E340FD70EFFC52B26

You can verify the checksum and signature like:

gpg --verify NanoDroid-19.0.20181027.zip.sha256.sig
sha256sum -c NanoDroid-19.0.20181027.zip.sha256

Additionally you may want to ensure the signing date is close to the release date.

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
    • download required files:
      • build-package pull to download all required apks and libraries for the Full, microG and F-Droid packages
    • build packages:
      • 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 bromitewebview to create the Bromite WebView package
      • build-package osmand for the OpenStreetMap (OsmAnd) package
      • build-package systest to create the SysTest package
      • build-package all to create all packages at once

      • build-package u-bromite to update Bromite WebView
      • build-package u-osmand to update OpenStreetMap (OsmAnd)
      • build-package pull to update/re-download everything

for apks downloaded from F-Droid repositories 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 (requires Android SDK)
  • ver [version] [date] change project version
  • bump increment Magisk module version by 1

The following applications are custom builds (see F-Droid Repository below):

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
Installing from scratch

This is the recommended way.

Stock ROM without GApps, custom ROM with/without OpenGApps

OpenGApps and GApps-less ROMs don't need further measurements, the Installer takes care of required steps.

  • 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
      • NanoDroid tries to get rid of GApps on it's own, but it may not always work, try without any warranty
  • 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
    • if you want to use microG make sure the ROM is either pre-patched with signature spoofing support or deoxeded so you can patch yourself see here
      • you can use the Patcher package to de-odex (up to Android 8.1) and/or patch services.jar (up to Android 9.0)
  • reboot into ROM

Stock ROM with GApps

Stock ROMs with GApps may not allow to switch from Google GmsCore to microG GmsCore in-place, thus the installation is slightly different.

  • 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
      • NanoDroid tries to get rid of GApps on it's own, but it may not always work, try without any warranty
  • install Magisk
    • recommended, but not required
    • if Magisk is installed, NanoDroid will be installed as Magisk-Module, else it will install into /system directly
    • if you want to use microG make sure the ROM is either pre-patched with signature spoofing support or deoxeded so you can patch yourself see here
      • you can use the Patcher package to de-odex (up to Android 8.1) and/or patch services.jar (up to Android 9.0)
  • install desired Kernel (if any)
  • mount /system read-write and remove the following folders
    • GApps GmsCore (which can have multiple paths, depending on the ROM):
      • /system/priv-app/GmsCore
      • /system/priv-app/GmsCore_update
      • /system/priv-app/PrebuiltGmsCore
      • /system/priv-app/PrebuiltGmsCorePi
      • /system/priv-app/PrebuiltGmsCorePix
    • /system/priv-app/GoogleServicesFramework
    • /system/priv-app/Phonesky
  • boot into ROM (ignore all those complaints that Play Services are missing)
    • this is step is required!
  • reboot to TWRP
  • install NanoDroid
    • if you want to use microG make sure the ROM is either pre-patched with signature spoofing support or deoxeded so you can patch yourself see here
      • you can use the Patcher package to de-odex (up to Android 8.1) and/or patch services.jar (up to Android 9.0)
  • reboot into ROM
Upgrade / Installing on a clean ROM

When upgrading NanoDroid or installing on a known clean ROM (read: GApps free), you may also just

  • 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 NanoDroid
  • reboot

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

If your ROM is odexed read this instructions on how to deodex services.jar manually

The Patcher supports installing the patched services.jar into the following locations:

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

So you can use it 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
      • if Phonesky (= Fake Store or Play Store) lacks signature spoofing permissions head to Settings / Apps / Permissions / Signature Spoofing and grant it
    • 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, ...)
    • in UnifiedNlp Settings choose either any or all of (whichever you've choosen to be installed)
      • Déjà Vu, Mozilla, Apple, Radiocell as Geolocation backend
      • Nominatim as Address lockup backend
    • after everything is done, reboot
    • if you installed Play Store open it, setup account and install your apps

Issues

List of known issues and their respective fixes or workarounds.

microG

  • 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.
  • You can't get past the first page of the microG login wizard on KitKat
    • either connect a Keyboard and use it to skip the first page (will work normally then)
    • use the custom NanoDroid microG GmsCore build, which has this issue fixed starting with version 0.2.6.14799-dirty-145

SafetyNet

  • Applications/SafetyNet check complain with Google Play Services are missing
    • you did not
      • setup microG (or did not reboot afterwards)
      • grant signature spoofing permission to Fake Store or Play Store
        • go to Settings / Apps / Permissions / Signature Spoofing and grant it
      • install either Fake Store or Play Store
  • SafetyNet check fails after upgrading Magisk to version 18.0
    • go to Magisk Manager > Magisk Hide and activate it for microG DroidGuard Helper
  • Applications crash during SafetyNet check
    • install microG DroidGuard Helper as user-app (required on some ROMs), as root, on-device, issue:
      • pm install -r /system/app/DroidGuard/DroidGuard.apk
      • this is done automatically in Magisk Mode (as of version 20.5)

Play Store

  • Play Store giving error RH-01
    • ensure you rebooted after microG setup
    • ensure Play Store has signature spoofing permission
      • go to Settings / Apps / Permissions / Signature Spoofing and grant it
    • force close Play Store and open it again

Push Messages

  • Apps are not receiving Push messages
    • go to microG Settings / Google Cloud Messaging and check if it is connected
    • ensure you don't have an adblocker blocking the domain mtalk.google.com it is required for GCM to work
    • when using Titanium Backup first install the app only (without data) and start it, this will register the app, after that you can restore the data using Titanium Backup
    • if an app is not shown as registered in microG Settings / Google Cloud Messaging, try uninstalling and re-installing it
    • when restoring the ROM from a TWRP backup GCM registration for apps is sometimes broken. You may use the following command to reset GMS settings for a given app using it's appname, or if no appname is given for all applications. Apps will re-register when launched afterwards:
      • nutl -r APPNAME (eg.: APPNAME = com.nianticlabs.pokemongo) or nutl -r

Unified Nlp

  • unified Nlp is not registered in the system
    • some ROMs with native signature spoofing don't look for com.google.android.gms as location provider
    • tell the developer (or maintainer) of the ROM to fix this
    • some versions of com.qualcomm.location conflict with uNlp, if it's installed and unified Nlp doesn't work, try the following command to get rid of it, as root, on-device:
      • novl -a com.qualcomm.location
  • unified Nlp is registered in the system, but fails to get location
    • issue the following commands as root, on-device:
      • pm grant com.google.android.gms android.permission.ACCESS_FINE_LOCATION
      • pm grant com.google.android.gms android.permission.ACCESS_COARSE_LOCATION
    • some versions of com.qualcomm.location conflict with uNlp, if it's installed and unified Nlp doesn't work, try the following command to get rid of it, as root, on-device:
      • novl -a com.qualcomm.location
  • Ichnaea (Mozilla) location backend doesn't provide location
    • if you use Blockada, add the location backend to the whitelist
    • for any other ad-blocker, whitelist the following domain:
      • https://location.services.mozilla.com

F-Droid

  • On some ROMs (most noticeably MIUI ROMs) F-Droid can't install applications
    • this is because F-Droid's Priviledged Extension is not compatible with those ROMs, disable it from
      • F-Droid > Settings > Expert Settings > Privileged Extension

Other

  • Some Stock ROMs do not properly work after first boot since their SetupWizard is disabled by NanoDroid (because it's incompatible with microG)
    • check /system/build.prop or /vendor/build.prop if they contain the property ro.setupwizard.mode and change it to (you can do this from TWRP via ADB, with the builtin vi editor)
      • ro.setupwizard.mode=DISABLED
      • in Magisk Mode NanoDroid will do this on it's own using Magisk's resetprop
    • if you can access your device via ADB, you can also issue the following command as root, on-device:
      • nanodroid-util --fix-update
  • Applications crash when using WebView (BromiteWebView package)
    • install Bromite WebView as user-app, as root, on-device, issue:
      • pm install -r /system/app/BromiteWebView/BromiteWebView.apk
      • this is done automatically in Magisk Mode (as of version 20.5)
  • ROM lags after applying signature spoofing patch
    • some ROMs already have the patch built-in, if you patch those ROMs (again), it results in heavy lags

Google Software

  • Hangouts isn't properly working
    • as root, on-device, run the following command:
      • pm disable com.google.android.talk/com.google.android.apps.hangouts.service.NetworkConnectionCheckingService
