The next generation Network Location Provider, based on plugins. Usually abbreviated as UnifiedNlp.

Release builds may be found on the release page.

Most modern ROMs come with support for non-Google geolocation providers. On these systems installation is easy:

1. Make sure that no Google geolocation tool is installed (it is usually listed as Google Play Services in Apps)
2. Download and install NetworkLocation.apk as a usual app (you may need to enable "Unknown sources" in Settings->Security)
3. Reboot and continue at Usage

Some ROMs, especially those not based on AOSP might have problems using this method. However, if your system has root, you can try installing the hard way:

1. Download NetworkLocation.apk
2. Mount /system read-write (from your PC, call adb root && adb remount)
3. Copy NetworkLocation.apk to /system/priv-app (from your PC, call adb push NetworkLocation.apk /system/priv-app/NetworkLocation.apk)
4. Reboot (from you PC, call adb reboot) and continue at Usage

Older Android versions are no longer officially supported. However I still provide a legacy build, that should be compatible with those systems. It is required to have a rooted system to install on Jelly Bean and older.

1. Download LegacyNetworkLocation.apk
2. Mount /system read-write (from your PC, call adb root && adb remount)
3. Copy LegacyNetworkLocation.apk to /system/app (from your PC, call adb push LegacyNetworkLocation.apk /system/priv-app/NetworkLocation.apk)
4. Reboot (from you PC, call adb reboot) and continue at Usage

UnifiedNlp alone does not provide any features, but acts as a middleware for multiple backends.Most of them can be downloaded and updated using F-Droid Here is a list of backends for geolocation and (reverse) geocoding known to me:

• AppleWifiNlpBackend - backend that uses Apple's service to resolve wifi locations
• OpenWlanMapNlpBackend - backend that uses OpenWlanMap.org to resolve user location.
• OpenBmapNlpBackend - backend that uses openBmap to resolve user location.
• MozillaNlpBackend - backend that uses the Mozilla Location Service to resolve user location.
• PersonalWifiBackend - Local location provider for WiFi APs using on-phone generated database.
• LocalGSMLocationProvider - Local opencellid based location provider backend
• LocalGSMBackend - Local location provider for gsm cells with separate database file (lacells.db)

• NominatimGeocoderBackend
• (...) Create issue or pull request to extend either list :)

After installing a backend, you can use UnifiedNlp by activating network-based geolocation in Settings->Location. Since KitKat, you need to select any mode but "device only", on older Android version this setting is called "Wi-Fi & mobile network location" (ignore any misleading texts saying this is for Google's location service, you don't have Google's service installed but UnifiedNlp 😄)

The API is available here. Documentation may be found in the README provided with the API.

You might also take a look into existing backends, to see how they work out.

UnifiedNlp can be built using Gradle. Current builds are done using Gradle 2.2, but other versions might work as well.

To build with Gradle, first download git submodules:

git submodule update --init

UnifiedNlp can be build as part of Android when building an Android ROM from source. Add this repo to your (local) manifest.xml, as well as the UnifiedNlpApi and extend the PRODUCT_PACKAGES variable with NetworkLocation for KitKat and LegacyNetworkLocation for Jelly Bean.

You can also directly invoke the compilation of UnifiedNlp by calling make UnifiedNlp or make NetworkLocation (respectively make LegacyNetworkLocation) from the build system root. Note that you need to add UnifiedNlpApi and MicroGUiTools to the build system for UnifiedNlp to compile:

  <project name="microg/android_packages_apps_UnifiedNlp" path="packages/apps/UnifiedNlp" remote="github" revision="master"/>
  <project name="microg/android_external_UnifiedNlpApi" path="external/UnifiedNlpApi" remote="github" revision="master"/>
  <project name="microg/android_external_MicroGUiTools" path="external/MicroGUiTools" remote="github" revision="master"/>
