I am a beginner of android programming. I built an application which is working fine.. but when i modify the source code( i mean that activity.xml which is inside layout folder) the output is not getting effected when i run the app second time.. i mean previous output is being displayed eventhough i modify the source code (for ex. adding a new button in source code is not getting effected in output) ..
I AM SURE THAT I SAVED THE FILE BEFORE RUNNING..
this question may seem stupid but i really dont know what's going wrong as i am new to android prog...
