Goodnight.
I continued doing some tests and found out a few more things about the APP problem.
1 - The 30 seconds until the App loads on the launcher seem to be linked to this configuration menu: Configuration> Miscellaneous> Network flow timeout = 30 seconds. And these are the exact 30 seconds he has to delay until he is ready to play music. I already switched to 1 second and did not change anything in the problem.
2 - Appearing the APP every time the HU is turned off and on again with the APP running, when turning it back on it scans the folders contained on the flash drive, and I imagine that this is not correct, it should do this only once and this contributes to the slowness in reopening the APP.
3 - The APP apparently also scans the web before calling, and how did I reach that conclusion? because I have a weather widget and it works to search the internet before showing me the data and coincidentally, as soon as it gets the data in the cloud, Poweramp opens next to this app, it is as if the two were waiting for data from the web to work.
Anyway, it seems that it is a matter of configuration, enabling some items and disabling others, the fact is that in the standard installation the APP does not work on my HU (Android Car.)
Since already thank you
