If you want to disable the Home, Menu and Back button.There is a way , find the key layout files found in out/target/product/generic/system/usr/keylayout. Open the Generic.kl file and make the below lines comments by adding a #

# key 158 BACK WAKE_DROPPED
# key 172 HOME

Need any further advice , I am here to help:) Referred from Disable hardware keys android rom

you should override the onBackPressed method in your activity

@Override
public void onBackPressed () {
    your code
    super.onBackPressed();
    ...
}

for home button it's depends on which actionBar are u using. take a look at: http://android-developers.blogspot.co.il/2014/10/appcompat-v21-material-design-for-pre.html
