4.3 rendering issues

[panzerdev]

the flip doesn't render right anymore. if you have no 4.3 device I can make a video.

[emilsjolander]

I recently saw this problem. I talked to Romain guy on the android team and it sounds like it's a android issue, they were working on a fix ;)

[panzerdev]

Great! I just disabled the upper and lower part of the image for API level 18 for now so it just flips without the card effect. Thx for the support! :-)

[emilsjolander]

i would suggest you use a viewpager on API 18 if at all possible :)

I have same error, but I don't know how to fix it. Please help me, thank you very much !

[emilsjolander]

there is no way to fix it now. I amrewriting some core parts of the library which will be released this or next weekend, hopefully that will help

[hoangpn412]

wait fix bug !

Look foward to your rewrite code.

[emilsjolander]

yeah, the rewrite is almost done. you can have a look in the preloading branch. This however does not fix the 4.3 bug which i will have a hard time fixing. Will look into work arounds

Hey, can you tell me why this app error with android 4.3

[hoangpn412]

Dear emilsjolander,

I downloaded preloading branch and run sample project. But the error in activity_main.xml is: The following classes could not be instantiated:

• se.emilsjolander.flipview.FlipView (Open Class, Show Error Log) See the Error Log (Window > Show View) for more details. Tip: Use View.isInEditMode() in your custom views to skip code when shown in Eclipse

[emilsjolander]

Ok i tested this on 4.4 and it works as expected. Confirming once again that this was an android bug. As 4.3 had fairly low traction i will not try to release a work around. closing issue now

Hi guys,

we fix render right problem changing 2 lines in drawPreviousHalf() and drawNextHalf() methods in FlipView class. Instead of drawChild(canvas, p.v, 0); we change to p.v.draw(canvas); Don't know if it's the right way, but now it works great also under Android 4.3.

Remains a minor problem on API 18: right half glitch after flipping animation ends. Any suggestion?

[hoangpn412]

No, it is not a good solution.

drawChild() ensures that the view is drawn using a hardware layer when supported, So this is not a good solution as this is a must to ensure good performance

Emil Sjölander: can you resolve this problem !

As it's a bug in only 4.3 so i don't feel like putting a lot of time into it. Will look into maybe doing some form of workaround for this version specifically
