Android Question Heap Memory Corruption in dlmalloc

[pgargom]

Hi Erel¡
I am developing an app that is executing a loop of html files in a webview. These htmls are stored in a sdcard. This files are loaded in the same webview in this manner:

Activity.RemoveAllViews
                Activity.LoadLayout("Interstitial.bal")
                WebViewInterstitial.LoadUrl("file:///" & File.Combine(File.DirRootExternal, "MuralShopping/Recursos/Proyecto_"&Otros.consultarValorFicheroConfiguracion("idProyecto")&"/Instancias/"&nombreInstancia&"/index.html"))

The app runs ok for 1 hour more or less,but then, when loop was repeated a lot of times correctly, this stop and crash with next error:

GC_CONCURRENT freed 388K, 48% free 6659K/12679K, paused 4ms+7ms
nativeDestroy view: 0x23d44e8
Unknown chromium error: -6

Is WebViewInterstitial a regular WebView?

 

[pgargom]

Yes it is.

Dim WebViewInterstitial As WebView

 

[Erel]

Seems like a bug in Android: https://code.google.com/p/android/issues/detail?id=26183

 

[pgargom]

Then... if this is true... its imposible to do an app that runs for a long time showing differents hmtl files?? (like an digital signage)¿?¿?

I tried to initialize webview component, and seems that app runs for more time... but finally it crash too.

 

[Erel]

The issue is true. You can see it in the link above.

Can you create a simple project that demonstrates it?

 

[pgargom]

I created a simple project where i execute a timer that works with a webview that load a html each 10 seconds and this were the results:

-if html works with an external css file... app crash after 3 hours about.
-if css code is included in html file, app crash too.

but if you works with a simple html that dont needs css code, project works ok and dont crash. And if you consult web pages in a server, like www.google.com, project works ok too.

 

[Erel]

You can try to remove the WebView and create a new one each time.

 

[pgargom]

I did it in my example. I define a new webview each time i load a hmtl file, but app crash too.

Then i tried to run the app, loading files from a http server wich is runnig in another device, but it crash too.

Note: css files contains animations too

 

[pgargom]

are there any way to show this html in the navigator of the device and then return to my application?

 

[Erel]

You can use PhoneIntent.OpenBrowser to open the external browser. If the user later presses on the back key then it will return to your app.

 

[pgargom]

I did it like you say me. But, animations in html only run the first time that it are called. Then, only watch statics html. Are there any way to reload tabs of external browser, or delete it to reload html like news?

Thank you so much¡¡

 

[Erel]

No. You don't have control over the external browser.
