Will or will be? I am studying Oxford Practice Grammar Book. I have seen this sentence below. Can we use "will be" instead of "will" in this sentence?      The meeting will start at half past seven.
"Will + be + verb -ing)" vs "Will + verb" ? Can someone explain me the constructions (or however they are called) with the "Will + be + verb -ing)" and the "Will + verb" ?
Using "on" vs. "in"? Consider the following sentence:     I am developing an application to be installed on Android.   And this:     This has been a major flaw in Android...   To be clear I am unsure of the usage of "in" vs. "on". When should I use "in" and when to use "on"?
