Pandora and Spotify will not stop on device disconnect under some situations #105

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
Device (phone) brand: Motorola
Device (phone) model: Droid Razr
Android OS version: 2.3.6
App version: A2.1 or main a2dpvolume 2.7.2, Pandora 1.5.18
What steps will reproduce the problem?
1. Use a2dpvolume to start Pandora and set volume on connection to car 
(HandsFreeLink is a Johnson Controls product also used in Acura, BMW, etc.).  
Works perfectly.
2. Turn off ignition, Pandora continues to play out of phone speaker.
3.

What is the expected output? What do you see instead?  Should stop.

Please provide any additional information below.
1) Tried Pandora re-start in a2dpvolume and disabling automotive mode in 
Pandora.  No change on either setting (4 combinations).
2) Unlocked phone and watched as I turned of the car's ignition.  Pandora goes 
from playing, to paused, and then back to playing.

I should also note that Stop-App-on-Disconnect is checked in a2dpvolume.  
Thanks!

A few more details...  This car worked perfectly with Pandora using my older 
HTC Incredible (what the Razr replaced).  And the Razr works perfectly 
delivering Pandora with my other car's GoGroove FlexSMART X2 Bluetooth system 
($45 << HandsFreeLink).

Are you saying Pandora would stop correctly with  the HTC?  Is it just on the 
razr that it does not stop?

GoogleCodeExporter commented 9 years ago 
So I think you are saying the Razr works with the GoGroove (I have one of those 
too) and the Incredible works OK witht he Honda but the Razr does not work with 
the Honda.  And, the only thing that does not work (Honda/Razr) is the stop app 
feature.  Please confirm.  If this is correct, then it is something about the 
Honda/Razr combination that is causing the problem.  Are you using the Smart 
Actions app?  I wonder if either the Honda or the Razr toggles the music pause 
and then my app toggles it again which sets it back playing.  Try unchecking 
the "stop app on disconnect" and see what happens.  My app will still try to 
stop the music but it won't try to kill the app.  It should leave Pandora 
active but paused so at least it is not playing.  Let me know how that goes.

I was using the Smart Actions app and have replaced it with a2dpvolume.  Smart 
Actions can start Pandora, if it was running and paused, on connection to the 
HandsFreeLink, but it also could not stop it on disconnect.  With the GoGroove 
it would stop OK, but the start required hitting play on the GoGroove after the 
car connected.  a2dpvolume is a complete solution for the GoGroove, but the 
HandsFreeLink has the problem as noted above.  I will try unchecking "stop app 
on disconnect" tomorrow with the HandsFreeLink.  I think I did give that a try 
today, but I'm not sure.  BTW, the HandsFreeLink has intermittent instability 
problems with recent Motorola phones which use the TI WL 1285C Bluetooth chip 
(e.g. Razr).  Interestingly enough, I could stabilize those problems by not 
copying contact information into the HandsFreeLink.  Sort of the worst kind of 
problem in that it is not frequent enough to deter all users, and distracting 
enough to possibly cause an accident.

Hi Jim, With 2.7.2 I tried turning off "stop app on disconnect" and that did 
not fix the problem between my Razr and HandsFreeLink.  With the phone unlocked 
I see the same playing, paused, playing resumed with Pandora after the ignition 
is turned off.  Might a selectable, say 5 second delay, on the stop action, 
which I assume is a start/pause toggle request, give HandsFreeLink and whatever 
software on the phone is involved, a chance to finish their thing and allow 
a2dpvolume to have the "last word" on play/pause?  Should I try 2.8.1?  Since 
2.7.2 works perfectly with my GoGroove X2, I was a little reluctant to try 
it...  THANKS!!! Jon

Here I will explain how this works.  If you don't know Java coding, you are 
about to learn just a little bit.  It is very similar to many other languages 
and showing you the detail will hopefull help you understand it a bit better so 
we can work threough what might be causing your problems. The first thing I do 
is check to see if music is playing.

{{{if (bt2.hasIntent()) {
            // if music is playing, pause it
            if (am2.isMusicActive()) {
                // first pause the music so it removes the notify icon
                Intent i = new Intent("com.android.music.musicservicecommand");
                i.putExtra("command", "pause");
                sendBroadcast(i);
                // for more stubborn players, try this too...
                Intent downIntent2 = new Intent(Intent.ACTION_MEDIA_BUTTON, null);
                KeyEvent downEvent2 = new KeyEvent(KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_MEDIA_STOP);
                downIntent2.putExtra(Intent.EXTRA_KEY_EVENT, downEvent2);
                sendOrderedBroadcast(downIntent2, null);
            }}}}

The above code checks to see if a package name is associated with the app to 
launch.  If you used a music playlist shortcut, no package name exists. I check 
Pandora shortcuts though and automatically use the right package.  The code 
above will just stop the music be sending the KeyEvent which mimics you 
pressing the stop button on the screen or via a Bluetooth device.  The 
HasIntent function is checking to make sure there is a real package name.  This 
is needed to be able to stop the app.  Once the above is done, the app should 
stop playing the music and remove the notify icon from the notification bar.  
This is required to be able to push it to the background where it can finally 
be stopped.  This next part tries to kill the app.

{{{// if we opened a package for this device, try to close it now
            if (bt2.getPname().length() > 3 && bt2.isAppkill()) {
                // also open the home screen to make music app revert to
                // background
                Intent startMain = new Intent(Intent.ACTION_MAIN);
                startMain.addCategory(Intent.CATEGORY_HOME);
                startMain.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                startActivity(startMain);
                // now we can kill the app is asked to

                final String kpackage = bt2.getPname();
                CountDownTimer killTimer = new CountDownTimer(6000, 3000) {
                    @Override
                    public void onFinish() {
                        try {
                            stopApp(kpackage);
                        } catch (Exception e) {
                            e.printStackTrace();
                            Log.e(LOG_TAG, "Error " + e.getMessage());
                        }
                    }

                    @Override
                    public void onTick(long arg0) {

                        if (am2.isMusicActive()) {
                            // first pause the music so it removes the notify icon
                            Intent i = new Intent("com.android.music.musicservicecommand");
                            i.putExtra("command", "pause");
                            sendBroadcast(i);
                            // for more stubborn players, try this too...
                            Intent downIntent2 = new Intent(Intent.ACTION_MEDIA_BUTTON, null);
                            KeyEvent downEvent2 = new KeyEvent(KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_MEDIA_STOP);
                            downIntent2.putExtra(Intent.EXTRA_KEY_EVENT, downEvent2);
                            sendOrderedBroadcast(downIntent2, null);
                        }

                        try {
                            stopApp(kpackage);
                        } catch (Exception e) {
                            e.printStackTrace();
                            Log.e(LOG_TAG, "Error " + e.getMessage());
                        }
                    }
                };
                killTimer.start();

            }
}}}
The first thing I do is open the home screen to force the app (Pandora in this 
case) to the background.  Since Android 2.2, an app cannot kill another app 
unless it is in the background.  Next I create a countdowntimer.  This will run 
the code in the onTick at the interval in the 2nd parameter (3000ms or 3 
seconds in this case).  The timer will call the onFinish piece of code once the 
time expires in the first parameter (6000ms or 6 seconds in this case).  In 
these functions I am calling the code below (stopApp) to stop the app. 

{{{ protected void stopApp(String packageName) {
        Intent mIntent = getPackageManager().getLaunchIntentForPackage(
                packageName);
        if (mIntent != null) {
            try {

                ActivityManager act1 = (ActivityManager) this
                        .getSystemService(ACTIVITY_SERVICE);
                // act1.restartPackage(packageName);
                act1.killBackgroundProcesses(packageName);
                List<ActivityManager.RunningAppProcessInfo> processes;
                processes = act1.getRunningAppProcesses();
                for (ActivityManager.RunningAppProcessInfo info : processes) {
                    for (int i = 0; i < info.pkgList.length; i++) {
                        if (info.pkgList[i].contains(packageName)) {
                            android.os.Process.killProcess(info.pid);
                        }
                    }
                }
            } catch (ActivityNotFoundException err) {
                err.printStackTrace();
                Toast t = Toast.makeText(getApplicationContext(),
                        R.string.app_not_found, Toast.LENGTH_SHORT);
                if (notify)
                    t.show();
            }

        }
    }
}}}
This will hunt down every process (PID) associated with the app and stop them 
one by one.

So, this will first stop music from playing, then push the app to the 
background, then this will try 3 times to kill the app waiting 3 seconds 
between tries.  I hope that helps.  It sounds like in your case the very first 
part does not work.  The app does not see or does not respond to the stop key 
event.  I tested it here and it works fine on Droid 3.  So this makes me wonder 
if HTC has not implemented the stop key functionality in their UI.  Or, maybe 
something is restarting the play.  Or, it is interpreting the stop key as a 
toggle pause but the device you are disconnecting from is also toggling it.  Or 
maybe you have a device that only disconnects one profile but leaves the other 
connected (common actually).  Many Bluetooth car stereos will hold the 
Bluetooth connecting active for many minutes after the key is OFF.  Another 
thought: are you turning OFF Bluetooth before you turn OFF the car?  That would 
cause this issue because I will never see this device disconnect.  Instead I 
will just see Bluetooth become disabled.  You should just keep Bluetooth 
enabled all the time.  It takes very little battery.

Try using the audio jack or power connection features in A2DP Volume as a 
virtual device.  Have it launch Pandora just like you have it configured for 
you car.  See if that works correctly so we can isolate the issue more.  This 
will help determine if it is relate to killing the app or rather related to 
Bluetooth.

More info: I just duplicated your issue on my Xoom.  It has ICS.  It does not 
seem to respond to the music stop either.  Now that I have duplicated it, I can 
work on fixing it and hope the fix for Xoom is the same for other devices too.

More info.  The Xoom does not stop Pandora when using Home Dock but it does 
work properly when using Audio Jack.  Home Dock changes the UI.  That could 
explain the problem.

Hopefully someone can provide some more insight.  I tested on Xoom, Droid 2,

devices.  The Droid 2 and Xoom will not work with the Home Dock mode.  They 
launch OK but will not stop the player.

Hi Jim, I'm not sure how to use a2dpvolume with my Droid Razr headphone jack, 
but I can tell you the headphone jack stops Pandora perfectly if I pull it out 
while playing Pandora after a normal manual start.  My old HTC Incredible had 
no problems with my HandsFreeLink Civic, and I very much missed that until I 
discovered how well a2dpvolume works with a GoGroove X2 and my new Razr.  I 
would be excited to try a bug fix for my Razr/HandsFreeLink/a2dpvolume combo, 
but I am very grateful for your application using my Razr and GoGroove!  
Thanks!  Jon

OK, I think I have it working now.  Tested on Droid2, Droid3, and Xoom.  All 
now close Pandora on disconnect of any device type.  Please test and report any 
issues here.  

One note: Pandora does not like being killed.  It will not relaunch from A2DP 
Volume once it has been killed by it until the device has settled a while.

I set it up so that you don't have to kill Pandora to pause it.  What i do is 
make Pandora thing you just disconnected your headphones.  Pandora looks for 
that to pause the music.

Hi Jim,  Lots of good feedback on 2.8.2:

Mot Droid Razr + Honda Civic HandsFreeLink:
Starts and stops Pandora perfectly!  For me it is perfect!!!
If I leave the phone unlocked when I turn off the ignition, I do see an error 
message saying GoToMeeting has encountered a problem and Android wants me to 
approve stopping it.  I wish there was a low risk way to remove the 
pre-installed apps I don't use.  No remnants of this message if I don't have 
the phone unlocked and look later.

Mot Droid Razr + GoGroove X2:
Does not start Pandora with restart application checked.  Unchecked it works 
perfectly.

THANKS!!!!
Jon

That for testing.  Glad to hear it is all working well.

I don't think that GoToMeeting thing is related to my app.  You can get rid of 
that stuff with a one click root.  Go here for details: 
http://jimroal.blogspot.com/ .  I would wait on the Razr until it gets updated 
to ICS though.  There are many threads on bloatware, forceware, crapware, etc 
on Verizon's forums and other forums.

Hi Jim, Just verified that application restart does not work with the Honda 
HandsFreeLink either, and that choosing a Pandora Radio Station does not seem 
to work beyond starting Pandora and playing whatever was last selected.  
Regardless Iam quite happy and hope these little details help you. Thanks!  Jon
--------
BTW I briefly owned a Samsung Galaxy Nexus with ICS and found it too buggy.  
Maybe the apps and ICS have matured since last December.  I was thinking I 
would not let Verizon update my Razr to ICS when that day came, given 
everything is working well, with a2dpvolume covering the last of my issues...

Original comment by jonfield...@gmail.com on 29 Apr 2012 at 3:08

GoogleCodeExporter commented 9 years ago 
The functionality of restart app is app dependent.  Some work better that way, 
others do not.  The option is there so you can find what works best for the app 
you are using.  It does not work well with Pandora so you should never use it 
with Pandora.  Always leave it unchecked with Pandora.  On other players, it 
does help.

Starting the wrong station is a defect.  I will post a new issue for this one.  
Thanks for letting me know.  I never use Pandora so I don't have these issues.  
That's why it really help to have people like you test and report.  Thanks a 
bunch!

I have ICS on my Xoom and it is not buggy at all.  ICS has been upgraded on the 
Nexus since release too.  I have friends with it and they like it.  If it were 
me I would take the upgrade when it comes.  However, your point is certainly 
valid.  If everything is working well for you, why change.

I launched issue 108 for the Pandora issue.  When I first tested it, I thought 
it did just like you said: opened Pandora to the last station.  However, I 
tried it numerous times since and it always worked correctly, it switched to 
the station I selected.  Make sure you uncheck app restart and retest for this 
problem.  Report results in issue 108 please.

Hi Jim, My phone auto upgraded to 2.8.5 from 2.8.2 and has had problems 
starting and stopping Pandora, with settings that worked fine yesterday with 
2.8.2.  It was only able to start Pandora correctly once today.  All the other 
times Pandora was not running at all, or running paused.  Stopping stopped 
working after I tried a phone reset for starting.  I plan to revert back to the 
older version unless you waive me off from that.  Thanks!  Jon

Strange.  I made no changes to that part of the code between 2.8.2 and 2.8.5.
