Android Question MediaPlayer (Skipping / Stuttering)

[Robert Valentino]

It seems my Music App starts and plays clearly only every once in a while

I say once in a while because sometimes it happens twice in a row, then it won't play right for 2 or 3 or up to 5 times then it will.

Is anyone having any problems with MediaPlayer (I am using a Samsung S7 and Galaxy Tablet SM-T580)

Same problem on both.

When it starts up and plays right it plays right forever.
But when it doesn't it doesn't ever.

Just exit restart and see. If bad exit restart and it will eventually start and play right

Sounds like it is Skipping / Stuttering or just out of sync with the speakers (kind of sounds like they are cutting in and out).

I make sure I call Release on the mediaplayers I am using when exiting

This is really starting to drive me crazy. Because i created a simple program that just starts and plays a single track and it starts perfectly every time and plays clearly. So I took my music app and stripped it down to nothing and it still seems to do the same thing.

Just don't even know how to go about debugging something like this.

ANY Help - ANY one

Thanks

Is MediaPlayer a process global variable? Do you initialize it only once when FirstTime = True ?

 

[Robert Valentino]

I have MediaPlayer in a my Service Process_Globals and was doing the Init in my Service_Start have since moved it to Service_Create but still same problem

Should I move MediaPlayer to my Activity?

 

[Erel]

Should I move MediaPlayer to my Activity?

It doesn't matter.
Are there any relevant messages in the unfiltered logs?

Try to reproduce it in a small project and upload it.

This is where I feel so stupid. Every time I unclick the Filter check box on the IDE.

A million messages start scrolling by and they don't ever seem to stop. I just can't catch any meaning full information before they roll of the screen (and out of the list box)

How can I cause these to be written out to a disc file on the PC or at least stop them from happening

Below is a group I caught and it seems like the audio level is being non stop changed (I know I am not looping in a change)
This is just after a startup and my program isn't doing anything just waiting for user input
The second group are with the program running and playing a track normally plays well but sounds like Sh..

The third group has some references to PreVolumne and PreGain makes me wonder if they MediaPlayer is having a problem with MP3Gain files (and all my files have been Mp3Gained)

I surely appreciate the help

Part of this stream I find interesting is that there seems to be a change of PreVolumne / PreGain goint on which might be generating the skipping studdering I am hearing/

All my files have MP3Gain settings (Could this be causing these messages)

I don't like to bump posts, but just wanted say what I have tried.

Reinstalled my Android (using Android-28) and installed JDK jdk1.8.0_191 to see if maybe I had a bad library or something corrupt on my drive.

No changes.

FOUND the problem.

I added a Volume SeekBar in my program and read the last played volume and was setting it on startup

Private Sub sMDB_ButtonBar_SeekBar_ValueChanged(Value As Int, UserChanged As Boolean)
           Log("Main::sMDB_ButtonBar_SeekBar_ValueChanged(" &Value &")  UserChanged:" &UserChanged)
           
                 Starter.gMyPhone.SetVolume(Starter.gMyPhone.VOLUME_MUSIC, Value, False)
           Else
                 Starter.gMyPhone.SetVolume(Starter.gMyPhone.VOLUME_MUSIC, Value, False)               

'               Log("Main::sMDB_ButtonBar_SeekBar_ValueChanged - Setting 2")
'               
'                 sMDB_ButtonBar_SeekBar.Value = Value   '  WHY I WAS DOING THIS I Do not know but this was causing the SeekBar to be called over and over again.
           End If
End Sub
