Sample not working

I have the same issue as described here - https://github.com/maddevsio/mad-location-manager/issues/2 I cloned the repository, built the apk and started it on the phone, but it doesn’t seem to work ok. See the screenshots of what happens when I press on buttons in the app:

I open the log file in SendDataCollector folder and there I can see a whole bunch of data, like that:

1527313200064|I|X-LOG|31007242 GPS : pos lat=55,593639, lon=37,478290, alt=217,394154, hdop=8,000000, speed=16,755537, bearing=21,427261, sa=0,800000
1527313200065|I|X-LOG|01007242 KalmanAlloc : lon=37,478290, lat=55,593639, speed=16,755537, course=21,427261, m_accDev=0,100000, posDev=8,000000
1527313202025|I|X-LOG|31009225 GPS : pos lat=55,593906, lon=37,478476, alt=217,249434, hdop=6,000000, speed=16,708115, bearing=21,522673, sa=0,600000
1527313202135|I|X-LOG|21009225 KalmanUpdate : pos lon=37,478476, lat=55,593906, xVel=-14,907940, yVel=7,544164, posErr=6,000000, velErr=0,600000
1527313204035|I|X-LOG|31011234 GPS : pos lat=55,594177, lon=37,478662, alt=216,945878, hdop=6,000000, speed=16,529324, bearing=21,998478, sa=0,600000
1527313204138|I|X-LOG|21011234 KalmanUpdate : pos lon=37,478662, lat=55,594177, xVel=-16,528880, yVel=-0,121148, posErr=6,000000, velErr=0,600000

So, the app actually gets the location data but does not show anything on UI of the app (I thought there will be the track shown on the map). Why doesn’t it show anything?

@al-t Hello. There is some misunderstanding here, my fault. Sorry for that. It’s not possible to use just accelerometer. We need TYPE_ROTATION_VECTOR (it uses magnetometer and accelerometer as I understood from sources) OR we need accelerometer+magnetometer+gyroscope(optional) for Madgwick filter. These two ones are used for getting phone orientation. With phone orientation we can use accelerometer as INS.

If you don’t have these sensors (magnetometer at least) you can use GPS only based solutions, just using realtime geohash filter (class in current solution). It will remove “jumps” from route at least. Also you can use this solution.

Hello there 😃 Seem’s like something wrong with sensors : there is no any information about acceleration in logs. So could you check that application has rights to get data from linear accelerometer , magnetometer and gyroscope sensors?
