다른 팁
do plz tell me the right emulator specification
I really like the GenyMotion to test my android application. It is much better than Android provides.
Download the Genymotion from here and add the emulator whichever you want later
error msg doesn't support opengles on device
and for the real device make sure your device support the OpenGL ES version 2 which your map required.
For the marker cluster you can read the docs here.
