Hi ,
Are you adding 2 APK files?
No, one apk only. According to 's [document][1], I just update a new apk file to replace the old one and a patch obb to the play developer console.
What is your method of installing the project onto your device when testing?
Download from play store.
How are you going about adding the patch into your project?
Press the update button on play store when the uploaded new apk and patch obb had been published.
Is this happening with every single project that you package, when using a patch?
Sorry, I only try this in a single test project.
the patch steps you provided aren’t being saved to: \Saved\StagedBuilds\Android_ETC1\ folder
I mean if I use unreal frontend to make a patch. There will generate a pak file under \Saved\StagedBuilds\Android_ETC1\ folder. Then I use jobb to zip this pak file as a patch obb, and upload to play store.
English is not my native tongue, so please forgive me if I makes you misunderstanding.
Here is the log when I got the xapk file validation failed message, hope it can give you some information.
[Log file][2]
And I think the xapk file validation failed message in the download screen is showed by DownloaderActivity.java at line 464 (in function onPostExecute). So maybe the reason of this issue is cause by CRC checking process in function doInBackground?
