Android 7 Error?

[jabawack81]

I get a strange error that seems to be related to a Android 7:

I'm personally testing the app on various phone with Android 6 (one plus one and HTC One m7) and everything looks normal but I got some errors on the play console and the only difference I can fin is the android version ( Samsung Galaxy Tab A 10.1 (gtaxllte) poking around I found out that in the plugin I've found out that you're using the version 3 of the "Client library for the Google Play APK Expansion files." and google has released the version 4.

Ok. I didn't realize. I'll update it asap.

[agamemnus]

Actually, can you try it with 4 and see how it goes?

[jabawack81]

OK no problem. Mine was simply a shot in the dark trying to be useful but I'll try and report back.

Hi– I'm experiencing the same error, but I'm not sure if it's specifically Android 7. I've got it running and downloading just fine on a Moto G4 on Android 7, but not a Samsung S7 (also on 7). I'd love any advice or clues you've discovered while troubleshooting. Thanks!

I gave for granted that the problem was on Android 7 because I tested my app on various device with Android 6 and it failed only on Android 7 but with your information I start to believe that the problem could be more relative to Android 7 on Samsung Device, I have absolutely no idea how this could be.

[agamemnus]

Could be related to certain defaults on Samsung devices?

[jg33]

That's it- Before launching the app, I have to enable storage permissions on the Samsung. Just have to do that programatically- maybe with this: https://www.npmjs.com/package/cordova-plugin-android-permissions. Thanks for your help!

[agamemnus]

Oh yes. We had some problems with that before but could not really solve it.

[agamemnus]

Please let me know if that solves it.

[jg33]

Yep! Seems to break things on Motorola, but I bet it's fixable.

[agamemnus]

Ugh. Why would it break things on Motorola?

[jg33]

Not sure. Maybe just a timing/ order of operations thing. I'll try to figure it out. Thanks!

@jg33 thanks that fixed for me.

[agamemnus]

Great. Thanks for confirmation. I won't close this yet, though, as I'd like to see if I can do anything to the code/documentation to fix this in the same way.

@jabawack81 can you take a look now on Android 7 again? We were having the same issue on our side with Android 7, but merging #113 has resolved it on our end.

[jabawack81]

@chipbell4 Sorry for the delayed response, this fixed the problem for me.
