Ground is a map-centric data collection platform for occasionally connected devices.

This is not an officially supported Google product; it is currently being developed by volunteers on a best-effort basis.

The project is currently undergoing major architectural and UI changes. Please check back periodically for updates. The stable demo version is in branch prototype.

Create google_maps_api.xml files in gnd/src/debug/res/values and gnd/src/release/res/values, replacing API_KEY with debug and release Google Maps API keys:

<resources>
  <string name="google_maps_key" templateMergeStrategy="preserve"
  translatable="false">API_KEY</string>
</resources>

You can generate new keys at:

https://developers.google.com/maps/documentation/android-api/signup.

Be sure the SHA-1 certificate fingerprint described in the API key generation instructions is
registered with package name com.google.android.gnd in:

https://console.cloud.google.com/apis/credentials

You can find the SHA-1 of the debug key generated by Android Studio with:

$ keytool -list -v -keystore "$HOME/.android/debug.keystore" \
  -alias androiddebugkey \
  -storepass android -keypass android
