• saving android activity state using save instance state 24 answers

i have application : when application starts,one row 3 edittexts created calling method called newproduct().the first of them focused , triggers creation of row of 3 edittexts.so,when last row focused,another row created dynamically. every columns inside different linear layout , gets added new arraylist<edittext>();,one of 3 columns.the values entered put inside string[],again,3 of them every column.

my questions following : 1.how can save on screen orientation changes? when change orientation,the values remain in 2 of rows because 2 rows created @ oncreate( newproduct method called,creates first row, , focused,so creates row).how can tell application create more 2 rows , keep values ?

2.how can make application keep everything,the number of rows , values , whole ui layout when user either exits app or app crashes.what want here when enters app again see state in app left last time.

thanks in advance , have nice day !
