Unfortunately App has stopped

cocos2d-x C++
#1

Hello guys, i am using cocos2d-x with eclipse. I’ve got a common problem: my hellocpp can’t last a lot. It crashes and I get the message “Unfortunately app-name has stopped” on emulator. I have read a lot of other topics but I couldn’t fix that.

The emulator is using GPU Host.

I’m using Ubuntu, and if i do “cocos run -p linux” i have the APP running perfectly. It doesn’t work at Android Platform. I’ve tried to install it in my phone, but with no success.

I have the newest version (cocos2d-x-3.0rc1).

The relevant information seems to be : Didn’t find class “org.cocos2dx.cpp.AppActivity”

Do you have that particular class in that particular activity ?

#3

Did you import libcocos2dx project yet, if yes did you import libcocos2dx project from your own project folder (link: [YourProjectFolder]/cocos/2d/platform/android/java). Do not import from source cocos2dx folder.

Hope this help.

#4

First of all, thank you for helping me.
nbthhief, i actually was importing libcocos2dx from cocos2dx folder. So I fixed it, as you said.

Fradow: i have nothing on that class, but it extends Cocos2dxActivity.

Now I get this error on logcat. Trying to solve… :slight_smile:

Hi,

just do this

JniHelper::classloader = cocos2d::JniHelper::getEnv()->NewGlobalRef(_c);

in JinHelper.cpp line 146, the bug fixed!
