    Now it links with the FBSDK 4.36 without problems, and after a few hours of work to adapt my code to the new API version, everything works!

    Excellent! There's someone in another post here asking about whether there are updated imports for the FB SDK. Perhaps you can help them, or at least give them an idea as to whether everything still works anyway. (using 4.36)

    android.os.SystemProperties

    If there's a class called that, it's undocumented.

     

    If you're after a unique id for the device, you're probably better off using something like this: 

    uses
  Androidapi.JNI.Provider, Androidapi.Helpers;

// **** NOTE: Use this value with care, as it is reset if the device is rooted, or wiped
function GetUniqueDeviceID: string;
var
  LName: JString;
begin
  LName := TJSettings_Secure.JavaClass.ANDROID_ID;
  Result := JStringToString(TJSettings_Secure.JavaClass.getString(TAndroidHelper.ContentResolver, LName));
end;

    (But I would not see Idxxx.dcu even in projects where I do use Indy, because there I am using the Indy which came with Delphi, so it is not recompiled with the project.)

    You would if you included the Indy source path. If the callstack says it's being used, you're using it.

     

    Does your app use any tethering functionality? That ultimately includes Indy units.

    I'm assuming he means any file-based media that it can access.

    will that tLocation use a lot of energy/battery or will it only be active each x minutes as defined in this line:

    That's just the timer. Battery life will be affected by the settings used with the actual location services, as determined by MonitoringDistance and MonitoringInterval. There's some information here about the best strategies to use:

    There's an image here with EXIF data: http://orchids.enwphotos.com/2013-1/310.html

     

    Which includes the camera make etc. I use a Chrome plugin to view the data: https://chrome.google.com/webstore/detail/exif-viewer/mmbhfeiddhndihdjeganjggkmjapkffm

    Since my Leica Typ240 equipment is not in this list, I'm assuming that is the cause of the errors I'm encountering when trying to open one of these files

    I doubt it, since the camera make and model is in text form, not an index to different models

    Wondering, however, if a descendent of one of the methods within CCR.Exif [or a simple, new one] can easily be written [and at what cost] to extract just the description and title [nothing more at present]

    Are you referring to Delphi code? Also, description and title are not known tags - perhaps you're referring to ImageDescription? There's a list here: https://www.exiv2.org/tags.html. Note that not all images will have anything in this tag.

     

    There's an answer on SO that suggests a simpler method of extracting EXIF at least in relation to JPEGs: https://stackoverflow.com/a/18624442/3164070

     

    There's also a couple of alternatives to CCR-EXIF, here: https://torry.net/pages.php?id=104
