Use the config Config.logLevel
to adjust the verbosity of the logging, from 0: NONE
to 5: VERBOSE
. The default is LOG_LEVEL_VERBOSE
. WARNING: Do not publish an app with LOG_LEVEL_VERBOSE

By default, the plugin stores three days worth of logs to its database. You may configure logMaxDays
) to store any number of days you wish.
Use the method Logger.getLog
to retrieve the current contents of the log from the database as a single String
. Warning: The log can be very large, several megabytes.
BackgroundGeolocation.logger.getLog(function(log) {
console.log(log);
});
You may also use the method Logger.emailLog
. This will fetch the current log and send it using the device's default mail client, appending the log as an email-attachment.
BackgroundGeolocation.logger.emailLog('foo@bar.com').then((success) => {
console.log('[emailLog] SUCCESS');
}).catch((error) => {
console.log('[emailLog] ERROR: ', error);
});
When testing at your work-station, you can observe the plugin logs in XCode:
When testing the plugin at your work-station, you should always observe the Android logs via adb logcat
. You can filter the log to receive only messages from the plugin by using the TAG TSLocationManager:V
(V
for verbose). It's also helpful to use chromium:V
so you can see console.log
message from your Cordova App.
$ adb logcat *:S TSLocationManager:V chromium:V

iOS location can be simulated in the iOS Simulator. In the Simulator->Debug menu:
If you wish to do geofence testing in the iOS Simulator, The SampleApp contains a handy JSON file of the the City Drive route which you can use to populate the plugin with geofences. The SampleApp has a debug screen which uses this JSON data to Clear & Load these geofences:
When deploying to the device, you can simulate location by installing the app Lockito from Google Play Store. You must enable Lockito in Settings:
Settings->Developer Options->Select Mock Location App
.
NOTE: Once you configure a route in Lockito, you'll have to manually engage tracking in the plugin to trigger a state-change from Stationary -> Moving either by SHAKING the device to simulate motion or manually by executing the bgGeo.changePace(true)
.
Unfortunately, Lockito has a bug which makes it fail to respond to geofences (it used to work in previous versions), probably related to this
The Activity Recognition System will sample the device's current activity as configured with #activityRecognitionInterval (ms)
(e.g.: 10000 means the system will sample the current activity every 10 seconds).
- Activity received: still, confidence: 100
-
When the plugin receives on of the "moving" activities (e.g.:
"on_foot", "in_vehicle"
) location-updates will be initiated. -
You can easily simulate the
on_foot
state by shaking the device vigorously until the next#activityRecognitionInterval
ticks over). You'll hear the sound "doodly-doo" when location-updates are initiated.
