Hey guys.

We’ve updated our game Snowball Mania to version 1.2 for Android and iOS and encounter now a problem on some Android devices.
We debugged everything detailed with iPhone and a Nexus 7 Tablet and had no issues.

Today we experienced major problems trying the game on other Android devices (LG Optimus L5 and Samsung Galaxy S i9000).

The game crashes directly at startup. It still works without any problems on e.g. the tablet.

 

It fails on initializing the Main Activity, I’ll attach the logcat output collected on the Samsung Galaxy S with Android 4.0.4

Do you have an idea what the problem could be and why it is only appearing on some devices?
Any help appreciated, this is a major problem as this version is online in the Play Store.

 

Thanks in advance.

Hi Peter,

I could not reconstruct a similar crash, could you please send us the complete log output and a download link to the apk in question to info@felgo.com ?

Thanks,

Alex

[Peter]

It seems as it doesn’t happen every time, the game is starting now on Android, hopefully it doesn’t happen to often to our downloaders.

Maybe you can find out something about it.
Nevertheless thanks for your help.

 

Cheers.

[Peter]

Various other collegues reported the same behaviour till now.

It’s always the same exception.

java.lang.UnsatisfiedLinkError: Couldn't load QtXmlPatterns: findLibrary returned null

 

I hope we can recreate this issue to get more Logcat output.

 

The only change in sources in this update was the integration of the Facebook plugin, I don’t think that QML/Javascript changes brought up this issue.

 

Cheers.

Hi,

we are sorry for that, as already stated the complete log output would be of interest. In the meantime we’ll also try to reconstruct the problem here with our devices. I’ll come back to you later…

Cheers,

Alex

Thanks, are you sure there is no filter set for console output? What’s the output before the exception even occurs?

Cheers,

Alex

[Philipp]

Hi!

You have to keep in mind that this is the internal crash report you can send to the developer as user if your app crashes.

 

We interpret the log output as the following. When initializing the MainActivity the system is not able to find a certain Library:

Caused by: java.lang.UnsatisfiedLinkError: Couldn't load QtXmlPatterns: findLibrary returned null

 

We were however able to create the bug one more time and with root access on the device export the log:

In normal, you should be able to retrieve a full log even without rooting a device. Your assumption is correct, we do however still not get the cause of the crash. Could you please give the following a try.

1. Connect the device for which your game crashes

2. Open a new shell session with the following command (entered in terminal):

adb shell

(If adb is not in your path environment you can find it in Android’s SDK installation dir under Android-SDK/platform-tools/)

3. Perform the following command in the shell session and post us the output:

ls -l /data/data/com.xxmassdeveloper.SnowballMania/lib/

Thanks,

Alex

This output is AFTER the game crashed. After it has crashed further attempts to start the game succeeded.

I’ll try to get the same output before the crash. I’ll be back soon 🙂

BR,

[Peter]

I tried several reinstalls now, uninstalled first, reinstalled and so on…

But the crash did not occur again, seems to be only randomly that sometimes some libraries are not correctly present after installation?

Sounds reasonable. 😉

The output should be the same, as the libraries get copied to this directory after installing the APK. Looks like all libraries are present, the bundled (concerned) library is also fine what I can say from the shasum. We’ll have a look at Google’s mailing lists and try to get a device on which the crash occurs as next steps…

Cheers,

Alex

Hi!

Any progress with this bug?

[AlexFelgo Team]

Sorry, not yet, we are still trying to find a device on which the crash is actually happening here. Did you get any further crash reports (phone models, Android versions)?

Cheers,

Alex

[loma_lis]

Hi!

 

I tried the first time to build my app on android.

 

On Desktop everthing works fine. On Android Phone, it crashes at start.
