android - Will opened database connections still be opened after a "close-all"? -

i found other posts way close activities :

intent intent = new intent(logout.this, mainactivity.class); intent.setflags(intent.flag_activity_clear_top); intent.putextra("exit me", true); startactivity(intent); finish();   if( getintent().getbooleanextra("exit me", false)){     finish();     return; // add prevent doing unnecessary stuffs } 

my question : if there opened database connection in activities , these opened connections closed or not when above code execute ?

just because you've added code activity:

if( getintent().getbooleanextra("exit me", false)){     finish();     return; // add prevent doing unnecessary stuffs } 

no, won't closed automatically. should close connections @ ondestroy method, example, make happen.
