Basic Android code flow -

lets have 1 main activity called "main", , other sub-activities work , return data. each time main gets called starts sub-activities 1 @ time.

main:

oncreate...{ intent i1 = new intent("com.bla.bla.activity1"); startactivity(i1); //get bundles activity1 , save variables.. intent i2 = new intent("com.bla.bla.activity2"); startactivity(i2); //get bundles activity2 , save variables.. intent i3 = new intent("com.bla.bla.activity3"); startactivity(i2); //get bundles activity1 , save variables.. } 

if understand correctly, activity1 created @ first, , destroyed. code resume , start activity2 or start activity1 again because main activity paused , resumed (assuming don't add onresume/onpause etc..)?

edit:

lets these sub-activities return 1 string each, , each string should saved in 1 individual column of sql entry @ end of main activity. main activity should collect 3 strings, save en entry , destroy itself. work, main activity has resume example @ intent "i2" after intent "i1" has done work , returned string. how result best achieved?

like alex said, wouldn't want that. want use different intents call different activities create flow program. main might lead activity 1, activity 1 leads 2, 3, or 4. if have several activities, can use switch statement determine activity want launch, based on conditions are, or not, met.

hope helps.

edit answer:

if want save variables different activities, want start second activity first, third, second, , on. create data database, can create object, , pass object activity activity, using parcelable interface. within each of activities want use methods save returned data database, see fit.
