how your mobile application is handled by softkeys .

hello friends ,  time of the day is changed and its AM in ma watch and posting or dealing with a interesting topic , these days after a long time , i am dealing or working in mobile applications . so i found something interesting , means something interactive which is used by all of us , in our daily life " how your mobile application is handled by softkeys . "

it is not very hard because we are comfortable with mobile and every day we use our mobile & specially our mobile applications . so what happen when you use your mobile applications and handle it .

so my question or my post is pointing some basic things which are hidden or added in some books , so who is not interested in developing mobile applications can not understand this concept so i tried my best to explain this properly . so friends , if you are interested than please go for JAVA & friends if you are in love with any language than i think you are the happiest person in this person .

so when ever you open some application in your phone ( touch or simple ) than , you will find two options in your screen , and so first how this options are created in your mobile screen and why they are always added at the same place .

now the real topic , comes in the field , please read this image very carefully and understand properly .
