We have been getting a lot of crash reports on google play with the following crash log :

This error only happens for devices with android version 2.3.3-2.3.7. This seems to be a common problem but no one has a solution. Has anyone solved this issue.

Some of the links reporting this problem are :

Couldn't load cocos2dcpp

this is the main application's name. "libcocos2dcpp.so"

you can find this in AndroidManifest.xml

<!-- Tell Cocos2dxActivity the name of our .so -->
    <meta-data android:name="android.app.lib_name"
              android:value="cocos2dcpp" />

also, in proj.android/jni/Android.mk

LOCAL_MODULE_FILENAME := libcocos2dcpp

i guess you changed the module name in Android.mk
