ObsMapp FAQ

When logging into the portals I get the message: "Login details incorrect" First, test whether your login details are correct by logging out on and then logging in again.

If your login details are correct:

Go (within ObsMapp) to Settings-> Portals, tick the box "Upload my observations to ...", and enter your username and password. Do not tilt your device while entering your data Check your name and password by clicking the "Check password" button Your device makes up its own capital letters, small letters and / or spaces where they don't belong, check this by enabling "show password" via the menu Check if your password contains', the software cannot handle that Enter your email address at username I cannot enter rarities / exotics / synonyms / subspecies ObsMapp knows all the types that also knows. Make sure you have downloaded the correct species list. If you want to import into Spain with the Dutch list, you will miss species. In such a case, download the Spanish list. The lack of certain species can also be caused by your species group settings. Start ObsMapp and go to Menu -> Settings -> Species settings -> Activities, dress, etc. -> [your strain group]. Here you can, among other things, adjust the rarity class of the species you want to see and tick that you also want to see exotics. (note: If you want to be able to select all types, choose 'Very rare')

I am not getting a (or a bad) location fix ObsMapp tries to determine a location based on network data as well as using the GPS. Network data often makes for a quick but inaccurate first fix. With GPS you can sometimes determine your position accurately to within a few meters. ObsMapp does not determine your position itself, your device does that. ObsMapp only reads this data.

No location fix:

Is the GPS on? You turn it on in the Android settings on your device itself. Has ObsMapp been given the correct permissions to use the location? Go to your device settings -> choose apps -> select ObsMapp and make sure all permissions are on -> restart ObsMapp. Make sure your device can get a location fix. In the house, in the vicinity of tall buildings and trees, and with heavy clouds, obtaining a location fix is ​​more difficult, the GPS can even indicate a different position than where you actually are. With a bad location fix it is best to stay in the same position and wait until you have a better location fix. I cannot enter [species group name]! ObsMapp only contains the species lists that you added manually during the first installation or afterwards. Only species from these lists can be entered. Are you missing one or more species groups? Download the lists of the relevant species group (s): Settings -> Download -> Species.

Why does the battery of my device drain so quickly? When using ObsMapp in the field, your phone is on a lot and the GPS is used a lot, this can cause your battery to drain faster. Tips to use less battery are to turn off WiFi / mobile data, make your screen as dark as possible and close ObsMapp between observations, so that your GPS uses less GPS. A backup battery is also highly recommended.

How do I specify a group composition? Example: you have seen 7 Pochards, 3 male and 4 female:

  1. Click on the male / female icon in the input screen
  2. Enter 3 man and click +
  3. Enter 4 woman and press ok, now you can save the observation

My device is broken, have I now lost all my observations? ObsMapp is automatically and regularly backed up to your SD card. Look on your memory card in the folder / obsmapp / backup, and secure the files contained therein. Do this as soon as possible to prevent the files from disappearing.

Here's how to restore observations:

  1. Determine which file contains the correct data for you. This is a zip file named: wn_ [date] [time] .zip. Pay attention to the date and size of the file.
  2. Rename this file to, and place this file in the folder [sdkaart] / obsmapp / backup
  3. Now restart ObsMapp and go to the observations overview. On this screen you now have an extra menu item in the slide menu: Restore. Click on this and you will receive a message whether the restore was successful or not.
  4. Restart ObsMapp, and you will see your old observations.

Does ObsMapp also use data traffic abroad? It is never 100% preventable that ObsMapp uses some data traffic. This can be with a version update (soon about 35Mb), when downloading species or uploading observations. Good preparation helps: download the species lists and maps of the countries you are going to at home. Upload your observations when you have WiFi.

can't upload! If you can't upload, and you get an "InterruptedIoException" message, it could mean two things:

  1. You have a bad internet connection
  2. The upload is very large (photos!), And during the upload your device goes into sleep mode.

I get an error message, what should I do? When you get an Android notification, it's usually a notification that starts with "ObsMapp has stopped." It is often possible to send a report. By sending a report you help us to prevent this error in the future. It is the way to send the right information. Also add extra information such as what you did exactly, whether it was one-off or reproducible, etc. The more information, the greater the chance that your problem will actually be solved. You can also report your error in the forum, or pass it on to

I get the message "Google Play Services not available" Google Play Services needs to be updated:

How do I send debug files? Sometimes you will be asked to submit debug files. You do that like this:

  1. On the main ObsMapp screen, click on the tile at the bottom left: Settings
  2. Click on the menu at the top right: Advanced Settings
  3. Scroll down, almost at the bottom is the option 'Send debug files', click on it
  4. Choose the E-mail option, and choose to send with Gmail
  5. Send the e-mail to:, and state the exact (!) Time (preferably to the minute) at which the problem occurred. Note: The log data sent is always from today and yesterday. So make sure that the problem you had is never older than 'yesterday'.

How do I take a screenshot? Sometimes when reporting a problem, you will be asked to take a screenshot. With 9 out of 10 devices, you do this by simultaneously pressing the on / off button and the volume down button. Hold those buttons for 1 or 2 seconds and you will see a screenshot (screenshot) being taken. Such an image is then automatically saved on your device and can be used to clarify a problem.

How do I add sounds to an observation? ObsMapp cannot record sound itself. So you need a separate app that can. A well-known, good and free app is Hi-Q MP3 Rec (Free), The sound you want to add must be in MP3 format. Some apps create files with the extension mp4, mkv or ogg, so they are not usable. ObsMapp must be able to find the recorded file. So you need to know where the app in question stores the sounds. For Hi-Q MP3 Rec (Free) this is the folder Recordings on your SD card. In ObsMapp, you can indicate this by going to Settings from the main screen, and choosing Advanced in the top right-hand corner of the menu. In the list of options you will see about halfway through three options to indicate where ObsMapp should search for sounds: MP3 directory 1, 2 and 3. Click on 1 of these, and browse to the correct folder and click on 'Select this folder' . If you now add an observation and click on the sound icon in the input screen, ObsMapp will search the above three folders and show all sound files, with the newest at the top. Select such a file and that file will be added to your observation.

How do I add multimedia myself? You can easily download the standard multimedia via ObsMapp: menu -> Settings -> Download -> Photos, sounds and information.

But you can also add files yourself. These files should then look like this: [sdkaart] / obsmapp / media /. [species group number] / [species number in 8 digits] + [source name] + [copyright] + [text]. [mp3 | jpg | gif | png | html] Example: /sdcard/obsmapp/media/.1/00000328+Wikimedia+Jan de Vries + Vliegende sneeuwuil.jpg The species group number and species number can be found on

Note the dot before the species group number. This point ensures that the multimedia files are not included in the media list of your device. Otherwise that list could become unworkable. This directory is not immediately visible for most apps. You will have to explicitly indicate that these directories should be shown.

It may be that unpacking all individual files to your device takes a very long time. What you can also do is copy the zip file to your device and extract it there with the ES File Explorer app, for example.

How can I upload (an) observation (s) that are already in the old observations again? This shouldn't be necessary. Once uploaded, the observations are on, and uploading again leads to double observations. But if observations were somehow lost, please follow the below:

  1. Start ObsMapp and go to your observations overview.
  2. Go to “Old observations” via the menu
  3. You will now see a list t with already uploaded observations
  4. From the menu choose “Reset observations”
  5. Enter the date range of the observations to be restored. Tip: If you still have the confirmation email from the first upload, you can get the dates here.
  6. Click Ok, and confirm whether you are sure.
  7. Go back to the overview of the observations (so go out of the overview of old observations) and you will see your old observations as not yet uploaded.
  8. Upload your observations now as usual.
  9. Pay close attention to whether the ObsMapp screen now shows that the observations have been properly uploaded.

How can I add POIs to ObsMapp? It is possible to add POIs (Points Of Interest) yourself. In the same way that birdwatching huts can now be shown on the map, other points that are important to you can also be placed on the map. To do this, create a file called [poi name] .poi. You have to save the file with points as a text file (txt) and then rename it with the extension poi: filename.poi, so for example McDonald.poi. You create a png icon (with the real extension png); restaurant.png for example. That is a small picture that you can make yourself and save it (eg in Paint) as a png file. The first line of the text file must start with "icon =", followed by the name of the icon to be placed on the map, without the extension. Optionally, you can extend this line with "; copyright = xyz", where xyz is shown on the card together with the name when the relevant icon is clicked. The following lines consist of the longitude, latitude and name of the POI, separated by a comma (unlike the first line where the separator is a semicolon!)

Example from mcdonalds.poi: icon = restaurant; copyright = mcdonalds 5,985,52,179, Apeldoorn South 5,564,52,169, Barneveld

You must place the above file mcdonalds.poi, together with the icon restaurant.ico, in the directory [sdkaart] / obsmapp / poi Periods and commas must be exactly like this. In your settings under locations you can (re) read the POIs. On the map in ObsMapp you can indicate whether you want to show the POIs via the menu at the top left. ObsMapp will then automatically find these files, and the 'mcdonalds' option will automatically appear in the View menu of the map.

How can I display geometries on the map myself? In ObsMapp it is possible to draw areas on the map yourself. You do that as follows:

  1. Create a geoms.txt file in the directory [sdkaart] / obsmapp / geoms.
  2. In this file you define your geometry. That geometry must be in geojson. You define 1 geometry per line. There are two possibilities for this: define the geometry itself (3a) or give a reference to the geometry (3b) 3a) Create a line in the geoms.txt file that starts with "geom" and is followed by the geometry. Example: geom {"type": "Polygon", "coordinates": [[[5.5, 52.1], [5.6, 52.1], [5.6, 52.2], [5.5, 52.2], [5.5, 52.1]]]} ; 3b) With complex geometries this is time-consuming because everything has to be on 1 line. Then use the construction "file [filename]" and in the file with the mentioned filename you will find the geometry, possibly over several lines
  3. Coordinates must be in lat / long (WGS84), exclaves and enclaves are not supported.
  4. Start ObsMapp, choose the map and select POI from the options, and select the Geometries

I can't use voice input when connected to mobile internet, but I can when connected via wifi. This problem appears to occur particularly in Belgium. Then try the following:

  1. Go to apps> settings
  2. Under Network connections, choose More networks and choose Mobile networks
  3. Tick Mobile data if it is off (if it is not already: set your work SIM card to 2g, 3g, 4g, then it will automatically set the other one to 2g)
  4. Click on Access Point Names and Select the work SIM card
  5. click on the three dots at the top right and then click on "default settings" or select '' as APN, and empty the proxy data
  6. Restart phone
