I am using the below code to download images from server and store the image in the local path,
and then i store that local path in a dictionary.
but when i try to create a sprite using the location stored in dictionary it gives “Fatal signal 11 (SIGSEGV), code 1, fault addr 0x0 in tid 21104 (GLThread 8101)” Error in android and crashes
it works fine in Ios Device
