Accessing an array shouldn't be all that expensive. If it's accessed through a class or object field, it's going to be slower. For example, this: byte b0, b1; b0 = mMemory.data[0]; b1 = mMemory.data[1]; is not as fast as: byte[] data = mMemory.data; byte b0, b1; b0 = data[0]; b1 = data[1]; Do you have an APK that demonstrates the performance? (We're always looking for a few good benchmarks.) Apple II or C64? --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Android Developers" group.
