You can find it on F-Droid

You can download directly from the releases.


You can help with translations on Crowdin.

You can also submit pull requests for bug fixes and new features.

I'm not very good at UIs, so any work with the layouts would be appreciated!

It's good practice to verify downloads. In recent releases, a PGP signature and an SHA256 checksum will accompany each .apk.

Import PGP Public Key from or just gpg --recv-key 6989CF77490369CFFDCBCD8995E7D75C76CBE9A9

To verify the integrity and signature:

$ gpg --verify ~/Downloads/gpslogger-71.apk.asc

To verify checksum:

$ sha256sum -c ~/Downloads/gpslogger-71.apk.SHA256

Setting up the code

The project is based on the Android build system plugin for Gradle. These instructions are for Ubuntu Linux with Android Studio, but for other OSes, it should be roughly similar.

Set up your Android Development Environment

Follow the instructions on the Android Developer Website to set up your computer for development.

Download and install Android Studio (there's also a snap)

Clone the GPSLogger repository

git clone git://

Get the Android SDK extra repositories

This project uses certain Android libraries, you can install them using Google's poorly implemented sdkmanager:

  echo y | $HOME/android-sdk/tools/bin/sdkmanager 'tools'
  echo y | $HOME/android-sdk/tools/bin/sdkmanager 'platform-tools'
  echo y | $HOME/android-sdk/tools/bin/sdkmanager 'build-tools;26.0.2'
  echo y | $HOME/android-sdk/tools/bin/sdkmanager 'platforms;android-27'
  echo y | $HOME/android-sdk/tools/bin/sdkmanager 'platforms;android-25'
  echo y | $HOME/android-sdk/tools/bin/sdkmanager 'extras;google;m2repository'
  echo y | $HOME/android-sdk/tools/bin/sdkmanager 'extras;android;m2repository'
  echo y | $HOME/android-sdk/tools/bin/sdkmanager 'extras;google;google_play_services'


Create a file called, pointing at your Android SDK directory.

cd gpslogger
echo "sdk.dir=/home/mendhak/Programs/Android" >

Import the project

Open up Android Studio and choose to import a project. Select the topmost build.gradle file under GPSLogger.

If you get an Import dialog, choose to Import project from external model


On the next screen, choose the defaults and proceed (default gradle wrapper)


Give it a minute and Android Studio will configure the projects and download the various libraries.

OpenStreetMap Setup (Optional)

Sign up for an account with OpenStreetMap and log in.

Click on 'oauth settings'

Click on 'Register your application'

Fill in the form with these details

Oauth settings

After registering the application, you will receive a 'Consumer Key' and a 'Consumer Secret'.
Place the keys in and

Dropbox Setup (Optional)

Sign up for an account with

Go to the Dropbox Developers page and click on 'Create an App'

Use these settings, but choose a unique name

Dropbox settings

After creating the app, you will receive an app key and secret (the ones in the screenshot are fake)

Dropbox settings

Place the keys in your ~/.gradle/ like this:


Replace the Dropbox app key to your AndroidManifest.xml file

<!-- Change this to be db- followed by your app key -->
<data android:scheme="db-12341234"/>


GPSLogger is composed of a few main components;


Event Bus

The Event Bus is where all the cross communication happens. Various components raise their events on the Event Bus, and other parts of the application listen for those events. The most important one is when a location is obtained, it is placed on the event bus and consumed by many fragments.

GPS Logging Service

GPSLoggingService is where all the work happens. This service talks to the location providers (network and satellite). It sets up timers and alarms for the next GPS point to be requested. It passes location info to the various loggers so that they can write files. It also invokes the auto-uploaders so that they may send their files to DropBox, OSM, etc.

It also passes information to the Event Bus.

GPS Main Activity

This is the main visible form in the app. It consists of several 'fragments' - the simple view, detailed view and big view.

It takes care of the main screen, the menus and toolbars.

The fragments listen to the Event Bus for location changes and display it in their own way.

Session and AppSettings

Floating about are two other objects. Session contains various pieces of information related to the current GPSLogger run, such as current file name, the last known location, satellite count, and any other information which isn't static but is needed for the current run of GPSLogger.

AppSettings is a representation of the user's preferences.

These objects are visible throughout the application and can be accessed directly by any class, service, activity or fragment.

Working notes for F-Droid

Use the fdroidserver docker image. Clone the fdroid metadata repo and make changes to the com.mendhak.gpslogger.yml file.

git clone
cd fdroiddata

# initialize the metadata repo
docker run --rm -v /home/mendhak/Android/Sdk:/opt/android-sdk -v $(pwd):/repo -e ANDROID_HOME:/opt/android-sdk init -v

# lint your metadata yml
docker run --rm -v /home/mendhak/Android/Sdk:/opt/android-sdk -v $(pwd):/repo -e ANDROID_HOME:/opt/android-sdk lint com.mendhak.gpslogger -v
docker run --rm -v /home/mendhak/Android/Sdk:/opt/android-sdk -v $(pwd):/repo -e ANDROID_HOME:/opt/android-sdk readmeta

# see if the latest tag will get picked up. 
docker run --rm -v /home/mendhak/Android/Sdk:/opt/android-sdk -v $(pwd):/repo -e ANDROID_HOME:/opt/android-sdk checkupdates --auto com.mendhak.gpslogger
docker run --rm -v /home/mendhak/Android/Sdk:/opt/android-sdk -v $(pwd):/repo -e ANDROID_HOME:/opt/android-sdk rewritemeta com.mendhak.gpslogger

# build
docker run --rm -v /home/mendhak/Android/Sdk:/opt/android-sdk -v $(pwd):/repo -e ANDROID_HOME:/opt/android-sdk build -v -l com.mendhak.gpslogger
