what is the export you use to make the APK? this is not a image/performance problem... if crashes is the wrapper......there is no game crashing because a large image...maybe loads more time but never crashes. and if its loaded then its cached and the performance should not be that much affected.
crashing apps usually results from bad wrapping format ... from my experience cordova/intelxdk does this.
try creating different apks using different wrappers and see where it crashes and where not.. if crashes on all then something is wrong with your project... or with jsminifier if you use it on exporting.
also are you using a deprecated exporter?
