Every build published on Auralys APK passes the same routine before the download button goes live. This page describes that routine plainly, so you know what checked means when we say it.
Step one: file check
We start from the app itself. The build must behave as the Auralys Music App should: an offline player for local files, with the formats, equalizer and playlist tools readers expect. Anything that disagrees stops here.
Step two: install on real phones
The APK is installed on our own Android test phones. We follow the same steps a visitor follows, from the countdown to the first launch permission, so the instructions on this site describe the install you will actually see.
Step three: the format pass
A mixed test library goes in: MP3, WAV, FLAC, AAC and M4A files, tagged and untagged, in folders and loose. A build passes when every file plays and the library stays organised.
Step four: long listening
Finally the player is used, for days, through headphones, a phone speaker and a Bluetooth speaker, with playlists built, reordered and updated over. Only then is a build published.
