[android-developers] Re: How to handle sequential touches?

You also replied so briefly, if as a non-native English speaker, he
was uncertain how you meant each word, he would not GET that "general
idea".

So I will restate it in a manner that should be more clear: 1) make
each separate touchable thing a separate View 2) write one touch
listener for each View, 3) in that listener, set a boolean variable to
be used as a flag: make that variable a variable of the Activity
containing all the Views; for now, don't think too hard about
lifecycle. Then you can check these flags to see whether or not the
user is selecting in the order you want.

Then, once you have all that working, if you want the app to work
correctly even if the user pauses or runs other apps in between, or
even if the system kills an app, read the online docs on Activity
lifecycle management, e.g., http://developer.android.com/guide/topics/fundamentals/activities.html,
especially "Managing the Activity Lifecycle".
