Flutter_file_picker: Crash on Android selecting a PDF file

[gerryhigh]

I am using the file picker with type set to FileType.ANY on a Pixel 3. If I select a file of type PDF then I get a crash as shown below:

java.lang.RuntimeException: Failure delivering result ResultInfo{who=null, request=33115, result=-1, data=Intent { dat=content://com.android.providers.downloads.documents/document/msf:2507 flg=0x1 }} to activity {}:

If seems somewhat similar to this issue: https://github.com/miguelpruivo/plugins_flutter_file_picker/issues/7

Hi,

What’s the target API of your app and also what’s the emulator version? Where are you trying to select the file (which folder)? Can you try with a different pdf a let me know if it works for you?

Thank you.

[gerryhigh]

Target API is 28. It is failing on my phone, not the emulator (my test on the emulator it worked fine as well). My phone is running Android Q B5. It appears to only crash when accessing certain PDF files. These files are in the downloads folder and were downloaded from the browser. I can open these files fine using the built-in viewer.

[gerryhigh]

A few other notes. The crash is fatal and shuts down the VM and thus can't be wrapped in a try/catch. A few more lines of the logcat.

Thank you for the details @gerryhigh, can you post the output of your flutter doctor -v with the running emulador (where the issue happens)?

Also, if you can give me with the steps to replicate it, it would be fine as it is quite hard to replicate some of these issues due to Android fragmentation.

Thank you.

To reproduce it's very simple. Just call await FilePicker.getFilePath(type: FileType.ANY); and pick the file and it will crash the app completely.

same error here, pdf files causes a crash in android.

[miguelpruivo]

@m7mdra in which device? There are some device/version specific issues that have been very hard to replicate so they can be fixed.

Thank you.

[m7mdra]

@miguelpruivo
im using pixle running android Q, i think that might be the problem.
its working fine in a real device but not when using emulator.
Thanks.

[m7mdra]

After testing on android P i can confirm its working fine.
thanks for the good job

[miguelpruivo]

@m7mdra usually I can’t replicate this issue on an emulator as it typically happens on real devices. If you are able to reproduce this issue on an emulator, would you mind to fully post your logs and the output of your flutter doctor -v with that emulator on?

Thank you!

[m7mdra]

@miguelpruivo for unobvious reason restarting the emulator fixed the bug, i tried to reproudced it but it worked so i guess its all good.

Thanks for following up.

[miguelpruivo]

@gerryhigh this should be fixed right now in the 1.4.0 that is yet on beta. Could you please try replacing in your pubspec.yaml like so:

file_picker:
    git:
      url: https://github.com/miguelpruivo/plugins_flutter_file_picker.git
      ref: beta

and let me know if it's working for you?

Thank you.

[miguelpruivo]

Version 1.4.0 published with these changes. Thank you for reporting. 🎉

@miguelpruivo I still have the same issue. I am using version 1.9.0.1.
