@kumarbhubnesh Can you share the code that reproduces this issue? Thanks in advance!

[kumarbhubnesh]

UriHelpers.txt Line no. 73 of this file. i have used this file from dropbox sample.

@kumarbhubnesh Apologies, I'm not sure I follow. Can you share any code that you wrote that triggers this? Or, if there is code in one of our samples that triggers this, can you link to the relevant sample and line? Thanks in advance!

[kumarbhubnesh]

UploadFileTask.txt
@greg-db This is the file from your sample which triggers it.

[greg-db]

@kumarbhubnesh Thanks! I just tried uploading a file using the Android example app that uses UploadFileTask on Android 7.0 though and it didn't reproduce that crash.

Can you share some more specific steps for reproducing this? Thanks in advance!

[kumarbhubnesh]

@greg-db Ok let me check that sample again,.

Any update on this?

[greg-db]

@nicolabeghin I don't have an update on this. Are you seeing this issue as well? We have not been able to reproduce it. If you can, please share the code and steps to do so. Thanks!

Hi @greg-db I just used the de-facto standard aFileChooser and just selected a file from the Dropbox app. I can confirm the _data column is not available, therefore throwing an exception at https://github.com/iPaulPro/aFileChooser/blob/master/aFileChooser/src/com/ipaulpro/afilechooser/utils/FileUtils.java#L330

Maybe your UploadFileTask is not crashing because you're uploading a file and not selecting one?

[greg-db]

@nicolabeghin I see, thank you. Based on this, I see that this error is actually more about interacting with the official Dropbox Android app (com.dropbox.android) and not the Dropbox API itself. I can only provide support for the Dropbox API part though.

Please open this is as a ticket here with these details and I'll redirect that to the right people. Thanks!

@nicolabeghin Did you resolve this? If you did, do you mind sharing? Thank you.

[nicolabeghin]

@HBiSoft if I'm not wrong I changed in aFileChooser to handle all files as "to be downloaded" like below. Not pretty if you ask me, but had no time to deep dive in this.

public static boolean isCloudFile(Uri uri) {
        return "content".equalsIgnoreCase(uri.getScheme());
    }
