Where (in which folder) are OSM maps stored? Dir changeable?
  • Vote Up0Vote Down psteinpstein

    Mapfactor Navigator downloads and uses e.g. OpenStreetMap maps.


    Where exactly are these maps stored on an Android v6 tablet?


    Can I somehow change the directory where the maps should be stored?

    you cannot change folder, it is restricted by Android

    @tomas Hmm, just tested, seems you are correct. On navigator 2.2.44 with Marshmallow (6.0.1) you're still presented with the choice where you would like the maps:
    Settings: Map Manager: Change installation SD-Card
    - Internal Storage
    - External SD Card 1

    Upon choosing SD Card 1, all OSM maps are copied to SD Card 1, not moved. When removing maps from Internal Storage navigator, navigator wants to download OSM maps again and will not work with maps on External SD Card 1.

    If v6 is detected is would it not be better not to present this option? As now its only a kind of backup?

    are you sure about this?
    may be something wen wrong?
  • Vote Up0Vote Down Jan_GruuthuseJan_Gruuthuse
    Yes, you see the copying going on. But the folder on internal is left intact with all maps in it. I deleted these files (all), Upon navigator restart you  get message no maps and get asked to download and if you don't download any navigator stops (exit).
    I'll try today with android V5 to see what happens there with that folder and its contents and report back.
  • Vote Up0Vote Down tomastomas
    I tested it and Navigator does move files
    problem is that Windows File explorer does not refresh until you disconnect/reconnect Android device
  • Vote Up0Vote Down Jan_GruuthuseJan_Gruuthuse
    Done test again after doing this powered of the device and restarted android 6.0.1.
    I'm finding OSM maps in Device on 2 places
    - /Tablet/Android/data/com.mapfactor.navigator/files/navigator/data
     when deleting above; navigator tells me no maps and want to download maps? [Cancel] closes navigator.
    - /Card/Android/data/com.mapfactor.navigator/files/navigator/data

    This would indicate (think) navigator is looking/getting maps from /Tablet/ and not SD /Card/

    Other items found on SD Card:
    mtp://[usb:002,010]/Card/Android/data/com.mapfactor.navigator/files
    [Download]
    [temp]
    mtp://[usb:002,010]/Card/Android/data/com.mapfactor.navigator/files/navigator
    [dictionary]
    [fonts]
    [images]
    [temp]
    [tmp]
    [warningsounds]
    - atlas.idc
    - dbs.map
    - default_album.style
    - default_editor.xml
    - default_teleatlas.map
    - navigation.xml
    - scheme_editor.map
    - tts.xml

    under 6.0.1 files are not moved but copied and left on its origin?
    placing [data] back into /Tablet/Android/data/com.mapfactor.navigator/files/navigator/
    navigator functions again.
    deleting /Card/Android/data/com.mapfactor.navigator/files/navigator has no influence at all.


    ps.: enclosed with square brackets represents [folder]

    I tested on Android 6.01 and found no problem
  • Vote Up0Vote Down Jan_GruuthuseJan_Gruuthuse
    There is no problem:
    6.0.1 is not working with maps on external SD card. It only copies the files there and keeps on using maps on internal storage.
  • Vote Up0Vote Down tomastomas
    it works with my SD on Android 6.01
    I am not sure why it would not for you - may be you set it as adoptable storage?

    I can confirm that Navigator works on Android 6.0.1 on both of my devices, Sony M4 Aqua and Samsung S4 on the external SD card in the above mentioned folders with no problem.

    SD comes up as portable storage (120 GB)
    I have the navigator app running on internal storage.
    When using navigator: settings: Map manager: Change installation SD-Card and change the internal Storage to External SD card 1 the app tells it moves the maps: it doesn't.
    The osm maps are left on internal storage and copied to SD card 1.
    Navigator works, when you now delete/remove
    /Tablet/Android/data/com.mapfactor.navigator/files/navigator/data
    navigator stops working.
    Indicating navigator does not use the maps on SD card 1.

    I have the feeling we are talking alongside each other.
  • Vote Up0Vote Down tomastomas
    I uninstalled Navigator, reinstalled to internal storage and downloaded UK, speed cameras and sounds
    then from Map manager moved to SD1 - Navigator was showing moving files
    all was moved correctly as expected

    Samsung Note 4 Edge, Android 6.01
  • Vote Up0Vote Down Jan_GruuthuseJan_Gruuthuse
    yes it is, when checking now you will noticed that items moved from internal to SD1 are still on internal.
    When running Navigator still internal files are used and not the ones on SD1.
    Test:
    ------
    Stop navigator.
    If present on internal delete: Android/data/com.mapfactor.navigator/files/navigator/data
    start navigator again.
    If asked for maps to download, you have the same situation: only internal storage is used.
    ------
    I always end up with DATA in 2 locations, only internal is used not SD1
    on Galaxy Tab S2 - SM-T810, Marshmallow (6.0.1), ARMv7-A
  • Vote Up0Vote Down tomastomas
    sorry, but after I moved data to SD1, all maps are on SD1 and none on Internal storage
    in fact, the whole navigator folder disappeared from internal storage
  • Vote Up0Vote Down Jan_GruuthuseJan_Gruuthuse
    That should not happen if you indicate only maps should be on SD1?
    Did you use the android application management => Storage => Used storage settings to move the app from internal to SD1?

    @tomas - this is part of SD card detection - Android OS has possibility to access one SD card by more path

    To prevent showing big amount of SD cards in Navigator there is test to detect if one path is the same SD card
  • Vote Up0Vote Down Jan_GruuthuseJan_Gruuthuse
    The android 6.0.1 (SM-T810) reports only in settings (Dutch OS):
    - Apparaatgeheugen (device memory)
    - SD-Kaart (sd-card)
    Filemanager:
    - Apparaatopslag (Device Storage)
    - SD-Kaart (sd-card)
    sd-card is external here
  • Vote Up0Vote Down hvdwolfhvdwolf
    This is indeed a big issue of Android over the several versions and per device implementation. On android versions 2.x and 3.x it was even worse.
    Internal memory is mostly: "/storage/emulated/0/......" or /mnt/sdcard/..."

    External memory (the real sdcard) is mostly: "/storage/extSdCard/..."
    But thse are not golden rules and sometimes differ (my sons Honor phone for example)

    And then there are devices without an external SDcard slot and they still "seem to" partition internal memory as internal and external memory, and present it like that to the user, while it actually mounts the same (internal) partition for both internal and external as presented to the user.
  • Vote Up0Vote Down hvdwolfhvdwolf
    @Jan_Gruuthuse: As you are using linux you can see that the actual partition displayed, regardless the name, is [usb: 002,009]. So the same partition mounted with a different name?

    If you do connect your tablet to linux and your go into a terminal and type "dmesg | tail"
    What do you see? What device with which partitions are mounted?

    Edit: sorry. I was wrong. The number of folders and files is different in your screenshots.
    Nevertheless. Could you try the "dmesg | tail" command?

    @Jan_Gruuthuse:
    You mention some posts ago that you configured your SD-card as "portable storage". That's not right. In Android 6 portable storage only allows for pictures and media, NOT data.

    (and there are more links about this issue/feature).

  • Vote Up0Vote Down tomastomas
    that is why I asked if it is not set as adoptable storage

    Choice between portable or internal storage does not present itself on Galaxy Tab S2 SM-T810. On format it is Portable.
  • Vote Up0Vote Down Jan_GruuthuseJan_Gruuthuse
    Something else is going on. As I can place several apps as running from SD card, even when formated as portable. How can you tell mapfactor is effectively running from external sd-card and not device storage?
    Whatever I do, I always endup with Android/data/com.mapfactor.navigator on both storages.

    You have very special hardware :)

    In your Android settings itself you should have some option for Storage (Opslag). Does that mention anything about internal memory and external memory and how it is allocated?

    And if you install one of the other nav apps like Osmand, Magic Earth, Maps.me, Navmii or so and install 1-2 maps. Do they move the maps to the external sd-card?

    That would also rule out whether it is a Navigator error or not.
