NeoStumbler

NeoStumbler is an Android application for collecting locations of cell towers, Wi-Fi access points and Bluetooth beacons to geolocation services, which have an API compatible with Ichnaea (i.e. Mozilla Location Services).

Downloads

There are two variants available:

• full - includes all features
• fdroid - does not include closed components (i.e. Google Play Services)
  • Features missing:
    • Fused location provider
    • Automatic scanning based on activity recognition
    • Cronet HTTP engine

APKs of the application can be downloaded from Releases page.

The fdroid variant is also available from F-Droid or alternatively from IzzyOnDroid. Reproducible builds are used for building NeoStumbler on F-Droid, which means that it's possible to upgrade an existing installation to a newer version from an alternative source.

Updates for the full variant have to be manually checked and downloaded from the Releases page. The fdroid variant can be automatically updated by the F-Droid application

Features

• Supports latest Android versions
• Collect data for cell towers, Wi-Fi access points and Bluetooth beacons
  • Data collection can be started automatically while moving (if using the full variant with Google Play Services)
• Scanning can be automatically paused when not moving
• Map showing the areas where data has been collected
• Exporting scan data as CSV files or as a raw SQLite file

Development

The application has two product flavors:

• full - includes all features
• fdroid - features dependent on closed-source components (i.e. Google Play Services) are removed

Building

• Build debug APK: ./gradlew buildFullDebug or ./gradlew buildFdroidDebug
• Build release APK: ./gradlew buildFullRelease or ./gradlew buildFdroidRelease
  • Note that by default this will build a signed APK
    • This needs a Java keystore file named keystore.jks in the project root directory and setting values for environment variables (see app/build.gradle)
    • Alternatively, to build an unsigned APK, remove signingConfigs block from app/build.gradle
