### 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](https://www.nanolx.org/apk/Phonesky.apk)
* Fake Store (reason: built with CHECK_LICENSE permission)
  * [Download Link](https://www.nanolx.org/apk/FakeStore.apk)
* microG GmsCore (reason: built with more recent spoofed Play Services Version, more)
  * [Download Link](https://www.nanolx.org/apk/GmsCore.apk)
* microG DroidGuard Helper (reason: built with fix for non 32bit arm devices failing SafetyNet attestation)
  * [Download Link](https://www.nanolx.org/apk/DroidGuard.apk)
* MPV (reason: infrequent updates, merge-requests included)
  * [Download Link](https://www.nanolx.org/apk/MPV.apk)

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.

  * everything mentioned in the Summary
* **NanoDroid-microG**: includes (only)
  * microG and it's companions
  * pseudo-debloat feature
  * app store(s)
  * GApps and location packages auto-removal

#### Installation Logfiles

The recovery log and installation configuration is stored after installation, regardless with it succeeded or failed.

You'll find the files in

* /data/adb/MODID_log_INSTALLDATE
* /data/adb/MODID_twrp_INSTALLDATE

where MODID is either NanoDroid, NanoDroid_microG or NanoDroid_FDroid. INSTALLDATE is the date of installation in %Y%m%D_%H.%M.%S format (eg: 20180709_20.34.14), **Note: when installing through Magisk Manager INSTALLDATE might be in UTC +0000, instead of your local time offset!**

In case of installation errors, issues or questions provide theese files in your report for easier debugging.

#### Parallel Installations

Since the microG and F-Droid packages are subsets of the Full NanoDroid package, they can't be installed alongside.

The microG and F-Droid packages however can be installed in parallel, as they complement each other.

## Installation

### Alter Installation

NanoDroid supports altering the installation settings to a wide degree.

Full [> Details](doc/AlterInstallation.md) 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.

* 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
  * 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

###### 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**
  * from either Magisk Manager or TWRP, doesn't matter
* 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
  * 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](https://github.com/Lanchon/haystack), 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](https://github.com/microg/android_packages_apps_GmsCore/wiki/Helpful-Information).

## TODO
