I get the following error when opening a csv file:

The permissions to read/write external storage are set in the Manifest, so reading a CSV from SD card usually works.

However, it is definitely missing permissions on the file, which leads me to some questions:

• Please could you give some more information on your device / system / version of Android?
• Which file system is used on the media?
  • was it initialized in Android device?
• Did you save the CSV through Android USB service, or externally on a PC?
• Can you read a CSV from another memory device? (i.e. internal)

Please could you also post the output of following command on adb command line

ls -l /storage/emulated/0/

Thx

I have Android 6 and all files permissions on /sdcard are: -rw-rw---- (AFAIR, /sdcard has FAT which doesn't have permissions so are set/masked by the system during mount and cannot be changed).

The 2nd answer from https://stackoverflow.com/questions/8854359/exception-open-failed-eacces-permission-denied-on-android could be relevant:

For API 23+ you need to request the read/write permissions even if they are already in your manifest.

What do you think?

-rw-rw----  1 root sdcard_rw   12 2016-12-01 01:42 a.csv

(created with Android's text editor)

(there's no real SD card in my phone, it's all internal memory)

This should be fixed now with the latest commit.

Unfortunately I don't have any Android 6+ device available for testing. Do you have a chance to build from the sources and test it?

I was wandering if it would be useful to use an emulator to test the program on Android M or N.

[ghost]

I don't have SDK setup to build the app from the source. I'm not sure, if I know how to do it.

[fr3ts0n]

Yes, they changed quite a bit in the file management. I will be able to emulate Android >= M after Christmas (with a new PC)

Thank your for fixing it!
