Android Pie Track Data Over Bluetooth - Google Pixel 2 XL Questions & Answers
I often play music over Bluetooth in my car. Before the Pie update the artist, album and track would show up on my car display but now I just get "No Data" or blank. Bluetooth still connects(actually better than on Oreo), pause, next/previous track buttons in car still work and track time still shows up(even if jumping forward/backward from the phone). It's just the track data that isn't showing. I use Black Player as my music app but the behavior is the same with the Google Play Music app as well.
Anyone else having this issue? Any solution?

Have you tried going into developer options and changing your avrcp version?

I did a Google search and found a post mentioning the same thing. I wasn't sure if it was related but I tried while it was already connected and playing. Changing caused playback to cut out for a second and resume but still no track data. I didn't try all of the option (1.3, 1.4, 1.5 and 1.6) and I didn't connect and disconnect in between. I guess I can try that. I'm really not even sure what AVRCP is.

It is the protocol used to transmit the track data to the head unit. Usually lower versions are more compatible. I had to set it to 1.3 in Oreo to work with my car, but with P the default seems to be working.
Not sure if it requires a Bluetooth reconnect. I suspect it would.
Bringing this up again to see if there is any new info.
Just a quick question. I have a Samsung S9 running Pie. I have the same metadata issue with a Subaru Head unit. While browsing my file system on my phone I found the following file in etc/bluetooth/iop_device_list.conf.
It contains the following. Any ideas as to what it is?

How to handle Bluetooth (AVRC) buttons on Hero?
Does anyone know what Intent (other than "Intent.ACTION_MEDIA_BUTTON") may be used to broadcast the bluetooth button presses (play/pause/FF/RW) on Hero devices?
Handling "Intent.ACTION_MEDIA_BUTTON" works fine for both wired and bluetooth buttons on G1 and MyTouch 3G phones.
On the Hero devices handling ACTION_MEDIA_BUTTON recognizes the WIRED headset's button press, but the bluetooth buttons go directly to the built in Android Media Player.
Here is the code I am using:
*For registering the intent Filter:
IntentFilter filter = new IntentFilter();
filter.addAction(Intent.ACTION_MEDIA_BUTTON);
filter.addAction("android.media.AUDIO_BECOMING_NOISY");
filter.setPriority(IntentFilter.SYSTEM_HIGH_PRIORITY);
registerReceiver(_Receiver, filter);
* For the receiver:
public void onReceive(Context context, Intent intent)
{
String intentAction = intent.getAction();
if ("android.media.AUDIO_BECOMING_NOISY".equals(intentAction))
{
//pause the playback
} else if (Intent.ACTION_MEDIA_BUTTON.equals(intentAction))
{
//handle buttons
}
}
Energy efficient apps
Which are the ENERGY EFFICIENT APPS but still SERVES the PURPOSE perfectly for basic needs like music = ? web browsing = ? im = ? launcher = ? notes = ? documents = ? Videos = ? Maps = ? Recording = ? (You can mention other categories also) Let your observations be HELPFUL (VERY MUCH) to others also.... And, lets list them out now....
i will start first i guess music = i am using UberMusic, but think that PlayerPro was better so far... web browsing = Opera definitely for me... im = ? launcher = Every launcher drains battery faster ... i am using LauncherPro... notes = Note Everything documents = mean file explorer ? ASTRO Videos = there is good player, but its not battery friendly at all, only thing to be used for is to watch movies... battery lasted 4 hours for me, it inserts subs itself, and its called yxplayer... For all the rest of the needs- stock. Maps = iGoMyWay ... and again, not battery friendly AT ALL, and i guess it cant even be Recording = not using any that would be me
If your that mad about power saving then UNDERclock your CPU. Sent from my HTC Wildfire S running cm7 with overclocked 806 cpu and data2whatever using XDA App
underclock a 600 mhz wfs .... bad idea... i would like throw it in a nearest wall
Android car radio app not remembering stations
Hi there, Ik have a radio in my car that is fully android 4.4.4 from an unknown chinese brand named joyous. All is working fine, except there is one thing that is bothering me, and that is the radio app is not remembering my presetted radio stations after it has been fully shut down. Im 100 percent sure it has continious power (it has been measured). Every other setting there is, it remembers, it continues playing my mp3 files where i left of, it remembers which source i used last time etc. Only the radio presets will not be remembered. Is this a known issue and are there other apps (apk) that i can install to try if these will remember there settings?
