Activity?"

Depends on the speed of the device.

To answer your question: it depends.

• Slower/older hardware will take longer to start an Activity than new hardware.
• If the target device is already running a lot of applications then the OS could have to kill them before your app can start, which could cause a delay.
• If you are performing some intensive tasks in your onCreate method then it will take a long time to start, and might not start at all if the OS decides it is taking too long.

you mean in the emulator?? depends on your machines specification, and also on the application size you want to load, in average the first load takes a lot like 1 or 2 minutes it is because it must load all the emulator setting turn the phone configuration on and a bunch stuff more... if the the emulator is on then it should take no more than 10 seconds to actually start your application running.
