Android Question Killing previous instance (main)

[peacemaker]

Why such error happened ?
App has many activities, but no StartActivity (Main) specially.

But sometimes when i open another activity - this happens and Main is started again.
Main activity uses OSM lib.

This is not an error. It tells you that two instances of the same activity were created. The first one was then destroyed. It usually happens when you open an activity from a notification.

 

[peacemaker]

Aha, yes, notifications are used, but i did not tap it - it needs to pull out ..... you know.

 

[peacemaker]

Can it be due to CallSub or CallSubDelayed ?

 

[Erel]

Does it cause any issue?

 

[peacemaker]

I have added checking
if IsPaused (Main) = false then Call.......
and, seems, no killing now.... need to check longer.

 

[peacemaker]

No, no luck. I even cannot open well other activities - after some pause - the killing, and Main activity is restarted.

App is used MapView (OSR) lib on the Main. The service woring with a server updates the SQLite db and call

    If IsPaused(Main) = False Then
        CallSubDelayed(Main, "Activity_Resume")
    End If

Where markers of the map are being updated.

 

[Erel]

Note that the code you posted will cause Activity_Resume to run twice. You should use StartActivity if you just want to show the activity.

If you can reproduce the issue in a small project then please upload it.

Why twice ?
I just need to re-draw the Activity (by Activity_Resume) from a service when it's on the display. Not twice :-(

 

[Erel]

CallSubDelayed will first start the activity and then call the target sub.

 

[peacemaker]

So, correct will be

    If IsPaused(Main) = False Then
        CallSub(Main, "Activity_Resume")
    End If

 

[Erel]

My mistake. I didn't read the condition correctly. If the activity is not paused then it will only execute once. Both CallSub and CallSubDelayed will work here.

Hey dude, I got the same behaviour that you described.

Have you fixed? Thanks

 

[Luiz Fernando Orlandini]

Erel, can you help me?
