Hi dear developers,
I'm having an issue with rhomobile application using GeoLocation module, as soon as I call GeoLocation.set_notification my application will start leaking memory eventually crashes when no more memory is available.
I've verified in the adb logs that the crash reason is outofmemory problem. I've started to monitor the app memory usage and I can see the leak live, it happens quite fast, when calling GeoLocation.set_notification with the default 0 parameter on my zebra device means getting callback around 3-4 times a second. Those callbacks seem to leak memory.
The ruby view itself is very simple with no complex logic, here is the code I use:
The memory leak happens even when if the !last_stop.empty? condition is never met, so that's not the case.
In the beginning the memory usage of the app looks like this: (adb shell dumpsys meminfo is.edico.delivery -D):
At 9:20:
At 9:33
It seems like "Private other" memory is leaking, most likely ruby or c code.
At 9:50:
It will take around 1-2 hours for the application to crash. Last time I checked my app was using 400MB memory in total few minutes before it crashed.
I've simplified my view and commented out most of the logic and the memory leak is still there.
Do you have any ideas how to fix this?
Best regards,
Krystian
I'm having an issue with rhomobile application using GeoLocation module, as soon as I call GeoLocation.set_notification my application will start leaking memory eventually crashes when no more memory is available.

Those callbacks seem to leak memory.
The ruby view itself is very simple with no complex logic, here is the code I use:
def geo_callback
@params.delete('rho_callback')
status = @params.delete('status')
if status != "ok"
return
end
satellites = @params.delete('satellites')
altitude = @params.delete('altitude')
known_position = @params.delete('known_position')
available = @params.delete('available')
accuracy = @params.delete('accuracy')
last_stop = Rho::RhoConfig.last_stop
curr_stop = Rho::RhoConfig.current_tripstop
if !last_stop.empty?
#calculate the distance
lat = @params['latitude'].to_f
lon = @params['longitude'].to_f
speed = @params['speed'].to_f
@params['ls'] = last_stop
@params['cs'] = curr_stop
last_lat, last_lon, last_ts = last_stop.split(',')
dist = ApplicationHelper.distance(last_lat.to_f, last_lon.to_f, lat, lon)
@params['distance'] = dist
#if distance from last stop is more than 50m or speed reaches ~ 18 km/h (5 m/s)
min_distance = 50/1000.0 #km
min_speed = 5 #m/s
if (dist > min_distance || speed > min_speed) && !curr_stop.empty?
Rho::RhoConfig.last_stop = ''
js = "EdicoHH.startTripStop(#{curr_stop})"
Rho::Log.warning("Starting tripstop journey to #{curr_stop}, last_ts: #{last_ts}, dist: #{dist} speed: #{speed}", "EdicoHH")
WebView.executeJavascript(js)
end
end
end
The memory leak happens even when if the !last_stop.empty? condition is never met, so that's not the case.
