RE: Problems with the volume of TTS voices in Navi Apps - PCB-Tech - 12-22-2019 (12-21-2019, 03:15 PM)hvdwolf Wrote: Android knows different "channels" for audio. On Android, "media" apps use the media channel. The radio is not an Android app. It is a piece of hardware in combination with an analog or digital amplifier, normally unknown to phones. Joying (and all other brands) use a custom made audio switching on their head units to make the radio heard. But why are the navigation systems so extremely quiet when no audio app is active, let alone music is playing? And why are the navigation systems completely muted when the GPS monitor is deactivated? Two different music players can run parallel and play music at the same time. But not even one navigation system alone can play sound. I find that somehow strange. And in the navigation systems, where I can select the channel, I either have no sound at all, or too quiet. Only Navigon does something different here. Because there TTS works. It also somehow overrides this "China mute". There music and navigation runs parallel. Whereby on the mobile Navigon made sure that the music was turned down for a short time. This does not work on the China thing. A strange behaviour. I would use Navigon, but it has been discontinued some time ago and is no longer updated.

When doing a reboot every app gets the shutdown signal and will "nicely" close everything. On the Joyings (and many other brands) a number of seetings are set back to default after a cold boot. The apps on the Joying (and on many other brands) are not so nicely written and do not write the settings to their database. The "KillAllAppsButSome" function simply kills every app that is not not in a specific "skipkillapp" list. So this is not a nice shutdown signal to the app, but a hard kill. My nokill mod simply deactivates that "KillAllAppsButSome" function. I give no guarantee what the other FYT/Joying apps will do exactly with their settings, but "everything" should stay as it was before going into deep sleep. I just posted the new mods for the 2019-11-28 firmware this morning. |
