Crash on specific Android Device

Hi, I created a simple app using NGUI and some character animations, it works fine on armv7 devices, but on armv6 devices, there are some crashes, listed below:

samsung GT-B5510 2.3.6 java.lang.RuntimeException: eglSwapBuffers failed: EGL_SUCCESS; samsung GT-I5700 2.1-update1 ANR(Application Not Response) found: keyDispatchingTimedOut;
samsung GT-I9088 2.1-update1 NDK error: fault addr 4eb59000;
samsung GT-S5360 2.3.6 java.lang.RuntimeException: eglSwapBuffers failed: EGL_SUCCESS;
ZTE U880 2.3.7 java.lang.UnsatisfiedLinkError: nativeFile;
ZTE U885 2.3.7 java.lang.UnsatisfiedLinkError: nativeFile;

I used Android 2.2 API Level 8 to build the apk, armv6 with VFP, OpenGL 2.0 and .Net 2.0.
