It is trying to load a file

  NotifySound.Initialize
  NotifySound.Load(File.DirAssets, "sound-notify.mp3")

and I am sure the file is included

What is status=64 and how to code for this error

[Robert Valentino]

Not sure any of them apply.

I'm just doing an Init and load when the crash occurs.

Wonder if on some devices you can't have multiple mediaplayers defined and loaded.

 

[Robert Valentino]

A friend suggested that I change the name to get rid of the Dash and make it an Underscore.

He says that he has found on some of these "knock off devices" they do not handle thinks like dash's very well.

Never heard that but worth a try.

NOTE: this is not crashing on anything I have but on some unknown device by a user

where are you intializing the mediaplayer?
can you upload a small project that this error can be reproduced?

 

[Robert Valentino]

No. As I said this is not happening on anything I have.

I have the logs turned on and when the system crashes it Emails me the log reports. (I trap it in the Application_Error in my Starter service as send the Email from there)
This happened to some user.

Wish I had more info

BobVal

are you intializing the mediaplayer in the starter service?

 

[Robert Valentino]

Yes

Code works perfectly for over a year now.

I'm going to wait and see what happens. I changed the file name from "sound-notify.mp3" to "sound_notify.mp3" (of course verified it works) and put up a new release

Wish I knew who the user was to tell them to try again.

 

[ilan]

i would suggest you to do 1 test

go to your android settings and then open "developer options"
scroll down to "Apps"
then check "do not keep activities" and also limit background processes (to "no background process")
and try your app on your phone.

the problem is lot of people think that enabling those settings will make their phone run faster and they start changing those settings that can cause problems on your app. that's why i asked if you intialize the mp in starter because if they have enabled those settings starter may not run on background and your activity could not access mp and because on your phone and also on most phones those settings are not enabled then your app works.

i would also suggest you to set mp in process globals in your activity and not in starter service because of this reason.
if you do that you will always have access to your mp because it is set in your activity.

 

[Robert Valentino]

WOW, interesting.

I have the code for all this in a Code Module (it's my GenFuncs class) and have a initialize routine that I call the first time (and YES this is being called the first time from Starter). In the initialize routine I initialize the MediaPlayer(s) - have multiple.

NOTE: Remember this is a Code Module so there is no IsInitialized routine so I created a variable so I could do a

if  cGenFuncs.IsInitialized = false then cGenFuncs.Initialize

So it kind of looks like a Class Module

Sub Process_Globals
  Public  IsInitialized  As Boolean = False

  Dim AlertBeeper  As Beeper
   
  Dim  NotifySound    As MediaPlayer   
  Dim  BowlingSound  As MediaPlayer   
End Sub

#Region Initialize
Public Sub Initialize
  IsInitialized = True
   
  AlertBeeper.Initialize2(500, 500, AlertBeeper.VOLUME_NOTIFICATION)

  NotifySound.Initialize
  NotifySound.Load(File.DirAssets, "sound_notify.mp3")

  BowlingSound.Initialize
  BowlingSound.Load(File.DirAssets, "bowling.mp3")
End Sub
#End Region

Public  Sub BowlingSoundPlay  
       BowlingSound.Position = 0  
       BowlingSound.Play  
End Sub

Public  Sub NotifySoundPlay  
       NotifySound.Position = 0  
       NotifySound.Play  
End Sub

If Starter is not running in the background I have a lot of other problems. I use it to download files, billing manager (get owned products).


I made the changes on my device and tried software runs with no problems.


Is there ANYWAY to check if this is a problem and give the user a ToastMessageShow to Fix their settings.

Do you really think moving MediaPlayers to main is really the necessary

Can u give me the link to your app so i can try to reproduce it? (google play link)

The starter service will run as long as the process is alive, assuming that you haven't explicitly stopped it.

 

[ilan]

Ok after testing i can confirm that the developer option is not the reason for that but i can also confirm that if you have in main activity a process global object that you want to access from a second activity then setting in developer option "do not keep activities" will kill the main activity and you will not be able to access those objects.

i have this problem in one of my apps. people like to play with those developer options and that could cause problems in some apps.
i thought maybe the starter service may also be effected of that but it seems like it is working.
