Nullpointer instead of Error message using getTrack on large tracks

[Falcosc]

Track content Provide behaives strange
cursor.getString(0): "track"
cursor.getBlob(1): null

And I did not get any errors logged from menion.android.locus.pro
Can we get any kind of indication if the Content Provider does not like our Tracks?

I imported my 26 hour and 300km long 9500hm MTB marathon. Export over ui works as well.
But even 5MB small GPX files cause this content provider issue.
I got 2,5MB working with 11.000 points

but Locus 4.28 did

DownloadErrorException  menion.android.locus                 W  onEnterForeground()

maybe the reason is stored somewhere.

If not, here is the large file

These are Details for a working track:
GPX Size 2,5MB
Point Count: 11.000
Blob Size: 1,5MB
locus.api.objects.geoData.Track size: 2,1MB

Track Blobs over 3mb cause trouble on Locus 3.7 and 4.28

[Falcosc]

@menion should we catch null pointer meanwhile as known issue or did you already think about a direction of this topic?

[Falcosc]

Do you like to get a pull request?

[menion]

Hello Falcos,
sorry, I'm quite busy on MyLibrary and the Locus API is a minor problem for now.

Well, bundles used in ContentProviders are usually limited to 1MB, while on modern devices, they are limited to 2MB. So problems here make sense and are hardly solvable with the method used now. Solution is using FileProvider in a similar way like sending tracks to Locus (over a temporary file). Later, sorry.

[Falcosc]

Oh, is it? I thought ContentProviders are the way to transmit more than 1mb intent limit.

2mb is fine for me, but it's important to know about this instead of getting null :)

What about an exception for tracks larger than technology limit to inform users and mention when this exception is most likely to be expected in method doc?

I guess locus maps catches the limit exception and just returns null into the content provider, at least that's how it feels looking on the cursor content.

Would it help you if I create a pull request to treat null as track too large exception and add a note in the method documentation about when it occurs?
