Cocos2dx Android OBB

Cocos2dx Android OBB
0.0 0

#1

Hello,
I am creating a game on Cocos2dx, but its apk size is crossing 150MB.
I want to add file expansion OBB from android studio.

Do anyone have link how to do that for cocos2dx project…

Thank you.

In cocos2d-x (i’ve tested it in 3.16) you only need to put the obb file into the correct folder and remove the Resource folder linking to assets. With that everything work fine.

Android Studio can’t copy the obb while testing, so you have to do it by yourself. I prefer it on the terminal with the command adb push main.X.packageName.obb /sdcard/Android/obb/packageName/ (X -> versionCode and packageName from your game).

Thank you @mars3142 for your reply.
I am trying to do in android studio, i am adding codes from https://gist.github.com/moust/7990925 link…

But while testing when i am putting resource file or .obb file into device OBB folder application is not able to find that file and while opening its crashing.

And while uploading apk with obb file to google play, its not downloading .obb file…

Could you please tel me proper way how can i implement it.

Thank you.

What’s your cocos version? And what’s the packageName, versionCode and OBB-filename?

The PlayStore should download the OBB file, if you install the game from there. If you sideload the APK onto the device you need to download the OBB by yourself.


#5

My cocos version is 3.16, packageName is “com.juegostudios.testIAP”, versionCode is 1,
OBB-file name is “main.1.com.juegostudios.testIAP.obb”.


#6

If you copy this file (and it’s a normal ZIP file) manually, cocos 3.16 should be handle it. I’m sure it worked, because I did it for my project as well, but I didn’t test the PlayStore upload yet. Only manual copy to sdcard.

Do you have Android M (or higher). Does the app have checked the runtime read permission? I read that API 21 to API 23 need this for obb files.


#7

I zipped the resource file and changed its name from resources.zip to main.1.com.juegostudios.testIAP.obb. and copied the folder to Android->obb->packageName(com.juegostudios.testIAP) folder.

and removed resources folder from the Game.

But when i am debugging Game to device api-21 its not finding main.1.com.juegostudios.testIAP.obb, and crashing…

Do i need to do anything else…???


#8

Runtime Permission? What’s the error message in the logcat?


#9

This is the error i am getting


#10

Don’t use upper case filenames. It’s best to use only lower case. Maybe this is the issue.

What’s the structure in the OBB? The file has to be at /CommonBG/ (without resources or something in front of it).


#11

I think its same because i just zipped the resources folder and changed its name to .obb…

Do i need to create a folder and put the resources folder into new folder and change the name of new folder…???


#12

I uploded apk or obb file on google play store, its downloading it, but while starting the app…
