android - Getting Exception: FATAL EXCEPTION: GLThread No configs match configSpec -

i using below code multisampling make smooth edge. below code working on mobile , other mobile getting exception 'no configs match configspec.

please me solve issue.

thanks in advance.

it looks requesting egl config test device doesn't support. not implementations support multisampling, want fall format that's supported on device. fallback format rgb565, , guess it's not supported on of target devices. try rgba8888 or rgba4444 instead, instance:

configspec = new int[] {         egl10.egl_red_size,        8,         egl10.egl_green_size,      8,         egl10.egl_blue_size,       8,         egl10.egl_alpha_size,      8,         egl10.egl_depth_size,      16,         egl10.egl_renderable_type, 4, /* egl_opengl_es2_bit */         egl10.egl_none }; 

as far know, rgba8888 16-bit depth buffer should available in relatively recent gles2 devices.
