hi,when i built apk for my android project,it is built successfully.and it works correctly
but in Application Output it is returned:

D/dalvikvm( 1231): GC_CONCURRENT freed 437K, 16% free 2960K/3492K, paused 6ms+4ms, total 247ms

W/EGL_emulation( 1231): eglSurfaceAttrib not implemented
D/        ( 1231): HostConnection::get() New Host Connection established 0xb85d99d8, tid 126

i replied myself.i found problem .when my app is compiled with emulator,this errors is returns when emulators that have the Use Host GPU setting ticked*
if Try turning that off, you'll no longer see those warnings (and the emulator will run horribly, horribly slowly..)
but we have not this warning.
In my think those warnings are harmless. Notice that the "error" is EGL_SUCCESS, which would seem to indicate no error at all!
goodluck
