Something has gone wrong with the uploaded file.No .apk file detected
The system could not detect a .apk file in the uploaded file.Troubleshooting:
Double-check that the file's extension is .apk.
If including an .obb file, ensure the ZIP file includes the .apk file.
If including an .obb file with your .apk file, the .obb(s) and .apk must be sent directly to a zipped (.ZIP) folder. The .zip will fail to upload if there are sub-folders.
