Android problem: cocos2d: CCZ: Failed to uncompress data

cocos2d-x C++
#1

I used expansion file(.obb) in my first coco2d-x3.0 android project, it worked fine in the local test( using adb push …), but now when i download the .obb file from the google play, i have problem with loading assets(encrypted .pvr.ccz),
and sometimes when i remove the app from the background apps and launch it again, it shows just black screen.

I have this message
cocos2d: CCZ: Failed to uncompress data

My texturepacker configuration:

My first customers complain, Please help me!
Thanks.

Any help , please i’m very need it :frowning:

#3

For a start Android doesn’t support .pvr texture files…

#4

@IslandPlaya

but cocos2d-x supports pvr format for android as i know.
and etc1 for ios too.

#5

Is there an error if not using expansion file?
There is a test case in Texture2DTest.cpp using prv ccz too.

#6

Thanks, no without expansion file it worked very good.

#7

May be the path is error.
After downloading, where is pvr.ccz file?
Have you added the path to search path?

#8

No, my path is good, because sometime it works and i load my assets normally, and other times it crashes because the engine is unable to uncompress somme .pvr.ccz( not all and randomly)

#9

After downloading, does .prv.ccz in a normal directory?

#10

Yes, it is, because before i run the app , i mount the .obb file, so it will be like normal directory.

#11

.prv.ccz in .obb? What’s the type of .obb?
Is it a zip file?
I think you should upzip it before using.

#12

.obb is like zip file , but we don’t unzip it ,instead we mount it , after this we can use the mounted file like normal directory (or like unzip file)

#13

You can mount it in you device, but how can you mount it in others? So i suggest you upzip it though i don’t know why mount can not work sometimes.

But if at the end you need to upzip it, why not testing it like this?

#14

because the mount is more simple than the unzip, and when i mount file in the run time the android give me a path of the mounted directory, after this i change my search path to the mounted directory.

#15

Did you mean you mount it by code in runtime?
I haven’t used like this.

#16

yes, in the java side i used code to mount the .obb file and return the path of the mounted file to the cocos2d-x side
