Android Question anr error starting from android 6.0

[Tempomaster]

Hello,

I've had a problem with an anr problem for some time. I can not solve it on my own. This problem only occurs from Android 6.0 . Until Android 5 there are no problems. it would really help if i could get a tip. I send in the plant the ANR log file and the affected java file.

The header for the error means:

executing service gd.tempomaster_pro/.svcoverlayinfo

In the log file is at the bottom:

- waiting to lock an unknown object ? Obviously something is missing.

Best regards,
Gunnar Daehling

android.os.MessageQueue.nativePollOnce - this one might be related to a call to DoEvents or a modal dialog.

 

[Tempomaster]

No DoEvents or a modal dialog. The service uses only sleep(0). In addition, short Wav files are played with the media player.

 

[Tempomaster]

I have used the following commands. Are these allowed?

Try
.
.
.
Catch
    Log("")
End Try

 

[KMatle]

Of course. How big is the code inside try... catch... ? If it's too much code, you get into problems (it's just for a few dedicated lines)

 

[Tempomaster]

Thank you. No, there are only a few lines. I was unsure with log ("").

 

[KMatle]

Log nothing doesn't make sense. Log "lastexeption" (see the syntax when you write try... )

 

[Tempomaster]

thanks, I'll try that.

 

[Erel]

Can you post the code of Service_Create and Service_Start subs in svcoverlayinfo ?

I don't know whether it is related or not but you shouldn't use StringFunctions. Try to remove it and see whether it happens.

Thank you. What kind of replacement is there for it.

Best regards,
Gunnar

 

[DonManfred]

All methods of the stringfunctions lib can be done with b4a commands. No need for a library

 

[Tempomaster]

@manfred

Thank you. I was not aware of that. I still have a lot to learn. But learning with B4A is a lot of fun.

Best regards,
Gunnar

1. I'm not sure that StringFunctions is the cause of this issue. Please report.

2. See the strings video tutorial: http://etp.b4x.com

I have followed your advice. Yesterday I still uploaded version 2.87 Beta. This morning I already got the first record of this mistake. I am very unhappy about it. I had already written in the last sixty days there are no problems with android smaller 6.0 .

Best regards,
Gunnar

Are you able to reproduce it yourself?

 

[Tempomaster]

Are you able to reproduce it yourself?

No. I have never seen the ANR window with me. My smartphone is running on Android 4.2.2. As a second device I use the emulator Nox with Android 5.1. No problem. I can not use the emulators of b4a avd manager. There I can only start the app. For the test of the gps function during a ride, I use the app "Lockito":

https://play.google.com/store/apps/details?id=fr.dvilleneuve.lockito&hl=de

I can not get this interaction working under other emulators.

 

[Tempomaster]

If someone wants to do this test is not a problem. In the app lockito simply set a route in Germany, Austria or Switzerland and let them leave. This app lets the smartphone drive virtually. It's best to drive in a big city like Berlin. There are most roads with information for my app set.

On the homepage of the app I show a demo how the whole thing works:

Users of the app are split into two camps. One group is very satisfied with the app. I have also received good reviews. The other group is complaining about the unstable app. The anr errors may not be signaled by a window. The overlay window simply disappears without comment. This window is generated by the library overlay window by Frédéric Leneuf-Magaud (Informatix).
