Hi,
Downloaded cocos2dx 3.0 alpha0 and tried building hellocpp sample it builds without any errors,after that i opened in eclipse and started running the sample with my android device connected,it started the sample and screen went black for few seconds and then it crashed.Dont know what is the problem if someone can help it will be really nice.
Please copy-paste the logcat output to help debug the issue. Please also tell the device and model on which the sample crashed.
It crashed in htc device,but before deploying to device i tried it in emulator,there also it opens and after few seconds it crashes,i cant give you the log now bcz i am in office. By this evening i will send you the log file,bt if possible you can also check hellocpp sample in the emulator or any android device with cocos2dx 3.0 alpha.As for as i know this version uses native activity for android i dont see any .java files,i am thinking problem exists due to that but i am not sure.Please let me know if you find the solution.
This is the log i am getting in emulator.

Hi I have the same error,
org.cocos2dx.helpcpp libc Fatal sign 11, could you find a fix?
I could solve this, With ndk-stack I could check the problem were the assets.

Where is the asserts? I cannot find the file named elf_file.h
Just wondering, are you trying to run from command line or from eclipse? You need to add the cocos2dx android project to your workspace. That is needed to be able to build and run the project. And what is where “org/cocos2dx/lib/Cocos2dxHelper” and other related classes are defined. This android/eclipse project is in cocos2dx/platform/android.

I have added cocos2d in eclipse and helloWorld can run on device, but the point is black screen and error.

How to solve this problem?thx.
I encountered this problem as well today.
Problem:
- The android project folder (proj.android) doesn’t not contain the java source, which include Cocos2dxHelper
Solution:
- Copy the java source at cocos2d-x/cocos/2d/platform/android/java to proj.anroid/src
Example:
from here:
$ pwd
/cocos2d-x/cocos/2d/platform/android/java
$ ls */*/*/*
Cocos2dxBitmap.java Cocos2dxHelper.java Cocos2dxMusic.java
Cocos2dxEditBoxDialog.java Cocos2dxLocalStorage.java Cocos2dxSound.java
Cocos2dxEditText.java Cocos2dxLuaJavaBridge.java Cocos2dxTypefaces.java
to here:
$ pwd
/cocos2d-x/projects/TestCpp/proj.android/src
$ ls */*/*/*
org/cocos2dx/lib/Cocos2dxBitmap.java org/cocos2dx/lib/Cocos2dxLuaJavaBridge.java
org/cocos2dx/lib/Cocos2dxEditBoxDialog.java org/cocos2dx/lib/Cocos2dxMusic.java
